Maki Gamou

Gamo-chan (ガモちゃん) is a supporting character of the Don't Toy With Me, Miss Nagatoro manga series. She is a first year high school student and Nagatoro's best friend. Gamo-chan is a confident, popular, driven and quite aggressive girl as well as the nominal ringleader of the 'cool kids' clique, which Yoshi, Sakura and Nagatoro herself are part of. She and Nagatoro shares a sort of friendly rivalry and, being aware of her friend's feelings for Senpai, she likes teasing him and pull unique pranks in order to help their relationship.

Her full name is currently unknown, albeit it's implied that "Gamo" - a rare originating from the  - may be her surname.

Appearance
Gamo-chan is an attractive, tall and statuary, first year high schooler with long, fiery orange hair - which she likely bleach, since they turns lighter in a gradient towards the tips - usually kept scruffy and a little unkempt. She has porcelain skin, although not delicate, and large, expressive orange eyes that perfectly matches her hair color. She has removable double piercings on her upper left ear, but those are usually covered by her hairs. She is the tallest out of Nagatoro's friends - almost as tall as Senpai - and is also the bustiest, albeit Yoshi reached her cup size after her summer puberty changes. An amazonian beauty, she has a toned, muscular, flexible and extremely athletic physique with well defined abs, a shapely musculature and generous breasts, a feature which is often Nagatoro's envy. Gamo-chan sports almost always a smug sneer and a fascinating eyelid which is higher than the other, also she has a tendency to thin her pupils whenever she grins.

She typically wears her school uniform consisting of a white button up shirt (with sleeves always rolled up and collar never buttoned) and a navy blue skirt completed with a pair of sneakers and dark soccer socks. However, in summer she wears a short-sleeved shirt in her uniform, while in winter she is shown to wear a light brown sweater and occasionally a blue blazer. She is also often seen wearing a circular bracelet on her left wrist.

When not at school she always sports a very stylish, glamorous, elaborate, rock-fashion and yet feminine choose of clothing.

Personality
Gamo-chan appear as an aggressive, harsh, sarcastic, cunning and bossy girl with a sadistic streak just as evident as Nagatoro's. She's the strongest bully out of the girls' clique and in a profile it's stated that she likes to mock people. An utterly outspoken individual, she's not shy in overstepping the boundaries or being rude to Senpai in both manner and words. However this is insinuated to be an act, as doing so she causes Nagatoro to go the extra mile in proving he's a worthy guy and ultimately bringing the pair closer together. Proving this, despite being Senpai's most vicious critic, she only insults Senpai when Nagatoro can hear it, while when they're alone and she can't defend him, she acted almost friendly. As time passes, regardless of keep making jokes questioning his sexual drive and manliness on several occasions, Gamo-chan got significantly kinder toward Senpai, treating him like one of her friends and acting very at ease with him, even to the point to easily admitting she find him someone who's "pretty funny" to be with.

Despite her general attitude, Gamo-chan is also very calm and level-headed as she never lose her composure and has proven to be quite patient and thoughtful. A "jerk with a heart of gold", regardless than always keeping a tough facade, Gamo-chan's actually sweeter and more caring toward her friends than she lets on; when she noticed Nagatoro was feeling bad for Senpai not swimming with them while they were to the beach she tried to cheer her up telling her that if he didn't wanted they couldn't force him, when she sulk at her due to the comment she made on her bust size Gamo-chan felt genuinely bad, explained what she meant by saying that big-breast were better and pointing out that regardless of that Nagatoro was "cute", she got really upset when Sakura got stalked, acted almost motherly to Yoshi over her fear of crossing the road and - as shown in an extra sketch of Volume 4 - took care of her when she gets lost in the crowd. While progressively taking a liking for Senpai, she also started to shown some of the same level of kindness and caring to him, making a plan to help him defeat the President and keep the art club active, supporting him during the school marathon, preparing him a special dish of her own invention at the sushi, reassuring him about Nagatoro's condition after she got a flu, inviting him to hang out with her clique for Christmas Eve and smiling happily in approval whenever Senpai shows a little backbone or Nagatoro does something that brings them a little closer together. As revealed in the Official Fanbook, she is considered a sort of "big-sister figure" among her friends.

She is very good friends with Sakura and Yoshi, who loved to follow her around and repeat what she says and does, while Nagatoro could be considered her best friend, despite their similar and often competitive personalities sometimes put them at odds in a sort of friendly rivalry. Also, Gamo-chan loves for teasing Nagatoro to fuel her feelings for Senpai sometimes push her to cause pranks that led the two to resorted to near-physical violence despite they seemingly always made peace rather quickly every time they fight. Being quite relaxed, Gamo-chan generally backs down in most situations, but it should be noted that she's the only character who's not afraid to fight Nagatoro when they really disagree. Also, judging by their friends' reactions whenever Gamo-chan and Nagatoro butt heads, it's not wise to make them mad, implying that they both has a temper warranting fear.

Although the President and the student council described her and her clique as "a bunch of good-for-nothing" Gamo-chan has actually proved to be an intelligent and scheming young woman, a natural-born leader as well as a talented organizer and planner; not only the others - Nagatoro included - follow her lead without questions, but she managed to create a YouTube sensation in less than a day in order to gather people at Senpai's art display and win the competition against the President at the same Culture Festival where she was already in charge to preparing an haunted house for her class and coordinated the girls in a matter of seconds to form a sort of human cart and transport Senpai during the school marathon, managing to overcome the Prez. Moreover, she's a karaoke enthusiast and a talented singer whose passion for  is visibly reflected in her casual attire. Also, an hidden depth of hers are her culinary skills which are praised by Senpai and also allowed her to criticize recipes in a quite specific and professional way.

Despite her beauty and apparent sexual confidence - never getting embarrassed from showing-off her body - it's implied that Gamo-chan is actually the less experienced with the other sex out of the girls. Likely due to her blunt and scary attitude, she's not as popular among boys as Sakura, Yoshi and Nagatoro; while the others have been all seen interacting with guys, Gamo-chan has rarely spoke to a boy in the whole series (the only exceptions being Senpai and when asking the games club members to be quieter), in one occasion two boys approached her clique to flirt, yet all of their attentions were for the other three girls, almost completely ignoring her if not to greet. Also, she went at the summer festival with Yoshi, while in Japan is usually attended by couples and, albeit not so uncommon going with a friend, it's mostly done by those who haven't a date. When at the beach, after noticing Senpai's stunned reaction while looking at her body, she seems almost flattered. On Christmas Eve, she got quite upset when her friends dumped her invitation to the karaoke because they had plans with boys, proving to be both sadden and - deep down - a little envious. Despite this, she reacted warm-heartedly at how obvious Nagatoro and Senpai were in wanting to spend time together.

She is also very athletic, loves the beach, and is a fantastic swimmer managing to race Nagatoro in a swimming contest, on the school cross country and even sharing her same proficiency in the same amount of martial arts styles.

Gamo-chan usually refer to Senpai calling him "Paisen" (パイセン), a play on the term "senpai" usually used in a cutesy, playful, or casual way.

Early life
Gamo-chan was born on June 15 in, , the eldest child of her family, she has a younger brother and a younger sister, whom she often take care of; due to her surname, her parents might originate from today's. She grew up in a house in the suburbs in the same apartment building of Yoshi's family, leading the two to became childhood friends. At some point she also started to study martial arts becoming very good.

Gamo-chan and Yoshi made friend with Nagatoro around their primary or middle school years, and after beginning to attend Kazehaya High School, they were all placed in the same class, 1-C where they became friend with Sakura, who eventually joined their group.

Even if since they reach teenhood her friend Yoshi often tried to be the matchmaker, Gamo-chan has never had a boyfriend nor any significant relationships with the opposite sex.

She joined the same club as Yoshi but it's unclear which one it is. Also she has sometimes joined the track and field clubs practice alongside Nagatoro.

Meeting Senpai
One afternoon, while chatting with her friends on the school's library a second year student walked in trying to stay unnoticed, until the pages of a manga he drew fell on the floor and are immediately spotted by the girls who started to mercilessly criticize it and making fun on him. Then, Gamo-chan received a text from an acquaintance of hers, Youko, who invited them all at a bakery called Mister Donuts, prompting three of them to go while Nagatoro choose to stay there.

Few weeks later, Nagatoro invited Senpai to have lunch with her, Yoshi and Gamo-chan at the school cafeteria, introducing him as his boyfriend. Her two friends recognized him as "the mangaka from the library" and, getting a little jealous that her friend has a boyfriend, Gamo-chan (and to some extent Yoshi) started to tease him and calling him names, causing Nagatoro to get angry and eventually taking his defenses, prompting Senpai to admit he wasn't actually her boyfriend. Gamo-chan and Yoshi burst out laughing at the futility of his statement and apologizing to him, admitting he was a very funny guy.

Somewhat curious of her friend relationship with the boy, and getting quite suspicious that she actually really has feelings for him, Gamo-chan visited the art club room together with Yoshi finding Senpai alone since Nagatoro has momentarily exited to borrow a comb in order to cut his hair. At first she simply looked around describing the place as the "love nest" of the boy and her friend, however after she saw the electric razor that Nagatoro left behind, she and Yoshy decided to try shave him themselves, Senpai opposed to them shouting that he already promised to Nagatoro he would have his hair cut by her. In that moment the girl went back, causing both of her friends to run off.

Some days after this, as for testing if Senpai was faithful to her friend, she went to the art club with Yoshi again, sat at his table and stared at him mischievously before asking him if he ever touched tits, saying that she felt bad for him since he never did it and eventually offering him to touch hers. Although he stares hesitantly at the prosperous girl, Senpai eventually decided to try leaving but was stopped and constricted by Yoshi who subsequently forced his right hand over her friend's left breast. Feeling bad for having been forced into be a sexual molester, Senpai then noticed the texture of the girl's tit felt strange, thus Gamo-chan revealed that she actually wore anpan undeneath her shirt. Right at that moment Nagatoro entered the room and her friends left.

Apparently, after seeing how utterly mortified Nagatoro was after catching them, Gamo-chan became sure of her friend's feelings toward Senpai and, from that moment on, began to tease them with the sole intention to make them closer, as that was the last occasion in which she actively bullied him.

Summer break
During the summer break Gamo-chan, Yoshi and Nagatoro decided to go to the beach and the latter invited Senpai too. The afternoon in which the group met, she greets Senpai saying she was surprised that he joined them, prompting the three girls to start mocking him by calling him a lonesome "wharf roach". After they arrived Gamo-chan stripped remaining in a bikini, which leave Senpai utterly stunned causing her to playfully taunt him for "staring way too hard even for a virgin" then Yoshi stripped as well showing-off her impressive bosom, causing Nagatoro to get frustrated, taking off her clothes as well, revealing her significantly smaller physique and demanding him to go buy drinks. Later, Gamo-chan proposed to go swim all together but Senpai refused, taking a sketchbook out of his bag to begin drawing. Following this, Gamo-chan had swimming competition with Nagatoro arbitrated by Yoshi. Nagatoro won and began to brag about how good she was as a member of the swimming club, causing her friend to remind her she was just a "bench-warmer" in the team and also they both swam in the front crawl rather than the breaststroke, which is the swimming style the club used. Then seeing Nagatoro wasn't listening to her but rather looking at Senpai all alone under their parasol, Gamo-chan tried to cheer her up telling her that if he didn't wanted to swim they couldn't force him. However, Nagatoro decided to to Senpai anyway and proposed him to rub a 50+ sunscreen on him after he told her about his fear of getting sunburnt, yet when he told that that would be something boyfriend and girlfriend would do, pointing out that they weren't, and she got offended, Nagatoro pinned him to the ground and started to rub the lotion on him with her foot in retaliation causing both Gamo-chan and Yoshi to join her in giving Senpai said treatment, prompting Nagatoro to stop after using the whole bottle and fully covering him on sunscreen. Then, the whole group ended up having a good time, making another swimming competition together, playing with sand and eating ramen at the beachside.

The night of the summer festival, Gamo-chan planned to go with her friends but, since Nagatoro was forced to go to school due to having a special club practice, she went there only with Yoshi. Surprised to found Senpai was at the festival too, she approached him and correctly guessed that he marched all the way there holding to the hope to meet Nagatoro, despite the boy denied it embarrassed, Gamo-chan informed him about why she couldn't come to the festival and, since he then tried to leave, caught him with a dog collar and asked him to accompany them around the festival. Then she sent Nagatoro a picture of all three of them together, proving that she expected Nagatoro jealous reaction and was quite aware of her friend's growing crush on Senpai. The plan set by the girl to made her friend jealous, thus prompting her to came, worked and Nagatoro run from the swimming club's lockers to the temple where they held Senpai "prisoner", lying that she finished earlier and only came there since she was free. Wanting to tease her friend/rival about her feelings for Senpai, Gamo-chan told her that if she wanted to free him she had to defeat them in some games at the festival. Competitive as always, Nagatoro accepted the challenge but not without insisting that she didn't care for Senpai at all. They began with a shooting game, splitting for a 2 vs 2 team battle in which the winner would have been the pair who managed to get the most decent prizes. Paired in the same team with Yoshi, after playing some other games, Nagatoro and Senpai managed to win a big squiddy peluches and, knowing Yoshi collected them, Nagatoro gave it to her, thus "bribing" her and winning the contest. Gamo-chan immediately freed Senpai from the collar, jokingly telling him to "pay attention not to getting caught again", and left together with Yoshi in order to let the pair enjoy some time alone at the festival.

New semester
The first day of the new semester, after class, Gamo-chan sat at the gazebo in the park close to Nagatoro's home chatting with Yoshi, Sakura and Nagatoro herself when they were approached by a couple of boys who started to hitting on them, although she remain rather aside in the conversation. When Senpai, who was looking at them from a distance too embarrassed to come any closer, stepped out of his hideout, Gamo-chan greeted him amicably and asked him to sit with them, giving the boy enough confidence to propose Nagatoro to walk home with him. The girl accepted, thus making Gamo-chan smile in approval, she immediately joined the pair alongside the other two girls and leave the two guys behind; after Senpai asked if it was okay for the girls not staying with them, they told him those two were "annoying" and started to jokingly tease him. All five of them smiled heartily.

The next day, after she and Yoshi skipped club practice and were punished, they met Senpai and Sakura in their classroom since the girl have asked him to help her bring there some boxes. Knowing Sakura seductive skills, Gamo-chan told Senpai to be careful since Nagatoro would snap if she saw him acting like that with her friend. In that moment a splinter inside the wooden box he was carrying went into Senpai's finger and Sakura offered to yank it off for him, while Gamo-chan and Yoshi immediately dragged him inside their classroom closing the door behind. Passing by the corridor, Nagatoro saw it, eavesdropped from behind the door, misunderstood that Sakura intended to "jerk off" the boy instead of "yank off" the splinter, get jealous and storm into the room angered only to discovered about her error; frustrated yet too prideful to admit it, Nagatoro simply took the tweezers from Sakura and yank off Senpai's splinter herself as her friends applauded.

Few days after this, Gamo-chan, Yoshi, Sakura and Nagatoro watch from their classroom window as the second year students were having a marathon, immediately spotting Senpai and marveling at how poorly he was performing, since he was way behind everyone else.

After the school cafeteria where Gamo-chan and her friends usually chat has been invaded by a group of boys they deemed as "loud and annoying" the girls turned to the teachers but they told 'em to solve it on their own, prompting them to decide to hang out in the art club room instead, while Sakura is working on seducing them one by one in order to sew seeds of jealousy in the group and making it collapse as they all began to compete for her attention. After they explained the situation to Senpai, complaining on how all men are driven primarily by their sexual desires, Gamo-chan teased Nagatoro stating that Senpai instead doesn't have any libido, prompting the girl to made a bet with her friend that if she find a lewd book hidden in the room by him she would have proved he was actually a quiet pervert. Nagatoro turned the room upside down, Senpai yelled he's not hiding anything, to which both Yoshi and Gamo-chan agreed despite Nagatoro stating that he was losing his cool since she was about to find his porn. After a while Senpai began to feel bad about Nagatoro losing the bet and, taking advantage of a moment of distraction from the girls, sneaked insid the prep room, where he hid Yagamirin Tarou's "Paradise Harem", took it and allow Nagatoro to find it. The girl was overjoyed and started to playfully tease him, while Gamo-chan and Yoshi watched the scene perplexed.

One day, Nagatoro noticed Senpai are having bento for lunch recently but the one she saw was very messed up, she made fun of him but then spent the evening preparing an homemade bento with the intention to share it with him the following day, confiding it to Gamo-chan; however her plan backfired since, feeling offended for her comments the previous day, Senpai has prepared an exceptionally well-made bento in order to teach Nagatoro a lesson. Marveled, Gamo-chan asked the boy to exchange a piece of her lunch with a bite of his bento and has a "foodgasm", thus trying to talk a stubbornly upset Nagatoro to taste it too. Due to Nagatoro refusing out of pride, wanting to help her, Gamo-chan suggested Senpai to swap a dish with Nagatoro, finding he was as determined as her friend in not asking for the swap first. In order to resolve the stalemate, Gamo-chan revealed that she was surprised Senpai made chicken that spicy as he wasn't good with spicy food while Nagatoro loved it, prompting the boy to admit it was actually too spicy for him, this granted Nagatoro the chance to ask for a swap making it seem like she was doing a favor to him; she gave Senpai the homemade dish she knew was his favourite ans Gamo-chan watched amused as her friend ate Senpai's chicken and has a "foodgasm" just like she and Yoshi has had.

After Sakura began getting stalked by one of the many boys who compete for her attention and asked Senpai to pretend to be her boyfriend in order to discouraged him from continuing. Jealous, Nagatoro tried to convince her friend to change her mind, calling Senpai "dangerous as a vermin", but she was ignored and caused the opposite effect convincing Senpai to play along with the gal's plan. The following day, being saturday, Senpai and Sakura went on their fake date while Nagatoro, Gamo-chan and Yoshi followed them recording everything with their smartphones. Gamo-chan teased Nagatoro saying it was like an anime plot when "two people went on a fake date but real feeling start to blossom" thus getting her friend frustrated despite firmly refusing to admit it. Before Senpai and Sakura could get too close, Nagatoro captured the stalker and forced him to promise that he would never do it again, putting an end to the charade despite Gamo-chan remained a little upset as she was actually planning to take shots of said date.

While they were all on the art club room, Nagatoro told Gamo-chan and Yoshi how she scared Senpai with the idea of repeat one year and be in their same class, thus making him fanatically study to pass the exam. Amused the three girls started to toy with the idea of what would they do if he failed the grade two times thus making them "his senpais". However, as the boy started to fear the three girls would have enslaved him if that ever happened, Sakura reassured Senpai that it won't happen because other than Nagatoro both she and the other two girls will have to take supplementary lessons due to their low academic results. Embarrassed, both Gamo-chan and Yoshi asked Senpai to tutor them, making Nagatoro jealous.

Culture Festival
After Nagatoro asked acquaintances in the handicrafts club to made her a perfect Nekotoro costume and insisted for Senpai to say something, getting really mad when he simply complimented how the outfit was well made, Gamo-chan and Yoshi peered into the art club room.

Later, posing for him, Nagatoro teases Senpai on making her look sexy while her friends laughed at his embarrassment. Then, the girls started to chat regarding what they planned to do with their clubs or class for the Cultural Festival, with Gamo-chan explaining she was in charge of the haunted house organized by their class. When Nagatoro asked to Senpai what would be the art club exhibition he stared into space and began remembering the previous year; then, after she woke him up from his memories, he answered that he would probably make an art display, causing the girls to said it would be boring and that they would give him an hand to fire it pu a little. While they all ironically suggested way to made his display more appealing, the boy heard some familiar footsteps and asked them to hid in the prep room right before the President entered with a stern expression. While the President told Senpai she was disappointed for him inviting people and being rowdy, eavesdropping on their conversation hidden in the prep room, Sakura, Yoshi and especially Gamo-chan all teased Nagatoro saying that beautiful older girl is probably Senpai's ex. After the President informed Senpai that she was thinking about disbanding the club leaving him unable to reply, Nagatoro came out of the prep room with her friends. Sporting her usual, calm expression, Gamo-chan watched as her friend confronted the President, eventually accepting her challenge in Senpai's stead.

After the President left Nagatoro started to do a mocking impression of her with her friends, prompting Senpai to stop them saying that they were the ones at fault and that they had zero chances of victory against her. To cheer him up the four girls all offered to lend him an hand, suggesting to make his display a "kitty-kitty cosplay art café", but Senpai began praising the President's talent telling them of the many awards she won and that the previous year the art club display ranked 6th in the popularity contest on over 50-60 exhibits. Hearing this all four of the girls realized Senpai has quite a crush for the President, much to Nagatoro dismay; however after Gamo-chan asked how could it be that an high schooler's painting ranked that high in a popularity contest Senpai shown them the President's picture that gathered so much attention: a nude self-portrait. The shocked girls all realized how it could have been that popular, prompting Nagatoro to said it was a lewd pornographic painting. Gamo-chan told everything the boy has to do was painting something equally amazing, to which Nagatoro replied she would have modeled for him, even wearing a swimsuit if he really begged her. Senpai replied that he wasn't confident enough to being able to match the President's talent, while Gamo-chan pointed out he was actually already losing a lot in term of "material of work", referring the President's massive boobs compared with Nagatoro's petite chest.

Nagatoro sulk at Gamo-chan for having dissed her, despite the latter explaining it wasn't her intention since she only meant a big-breasted model usually gathered a bigger crowd, also she told her that being a little cute is nothing paragoned to a body like the President's, however Senpai claimed that both Nagatoro and the President are charming in their own way, finally prompting Gamo-chan to apologize to her friend. Heartened, Nagatoro asked Senpai how she preferred to paint her, however he told her that he didn't want to use her as his model since if he dragged her into that match and lose it would be embarassing for her. Offended, Nagatoro stormed off the room, soon followed by her friends, all of whom lightly scolded him for hurting Nagatoro's feelings. Over the next days, after Senpai asked Nagatoro to be his model and started doing sketches of her even while eating with the rest of the group at the cafeteria, Gamo-chan asked him why he was doing it there, prompting him to answer he wanted to try creating a slice-of-life on Nagatoro.After he shown his paintings to Yoshi, Sakura and Gamo-chan, they were all impressed by them and the latter told him is like he looked at her as a lover, embarrassing both Nagatoro and Senpai. Then, Gamo-chan suggested to sneak a peek at the President's work, convincing all the gang to do it except for Senpai; however after seeing it the girls came back shocked and Nagatoro fainted. Thus, Gamo-chan and Sakura planned to be "cunning" as the President and began to make a plan to fight back against her new work and, although Senpai claimed they didn't needed to do anything weird as it was a problem between Nagatoro and him, the girls thrown him out of the room telling they would do their best to ready her up. Then they choreographed a dance featuring Nagatoro in her cat costume, together with Yoshi and Sakura wearing mascot costumes, the "I'll Bully You Dance" and uploaded it on YouTube making it the talk of the school also selling some related straps, that became amazingly popular.

The day of the Cultural Festival, the girls entered Senpai's diplay and Nagatoro performed said dance, prompting people who have seen the video began gathering all around the display to be willingly bullied by the so-called "Toro Cat". A boy complimented the paintings and asked her out, making Senpai jealous, then, although she seemed not interest as always, under her friends pressures - especially Gamo-chan - she started to act with the boy like she always do with Senpai, causing more and more people to came in order to be treated in the same way. As the hours passed lots of people also went to see the President's new nude self-portrait, however Senpai's exhibition seemed to gathered more interest.

At 12:10 Gamo-chan made Senpai and Nagatoro to go get some food so that they can spent some time together. When Nagatoro - mad at Senpai for having been complimented by some girls - try o make an excuse saying she couldn't just leave the exhibition as she was sulking at Senpai, Gamo-chan replied that Yoshi and Sakura could work harder to fill the void; however after Sakura revealed she had actually sneaked away to take some ice cream leaving one of the boy who adore her as a sostitute in her mascot costume, Gamo-chan get mad and started to beat him alongside Yoshi.

While the President is escorted away due to her painting being deemed as "too immoral for a school" by the student council, Nagatoro and Gamo-chan forced her to admit they have won the match as she lose due to disqualification and, after exulting with Yoshi and Sakura, in order to further humiliate her the girls forced the President to wear a skimpy bunny suit and sell their straps all over the school. After getting a sold out they allowed her to go and, while Gamo-chan was counting the money they obtained from that, Nagatoro said she would have taken a little walk around too, although all of her friends cheerfully realized she was actually planning to go to Senpai to invite him at the live concert, causing Gamo-chan to smile kindly and wishing her "good luck".

The following day, Gamo-chan and Yoshi met Senpai and Nagatoro on the street after she hit him for having accidentally groped her right breast, and greet them nonchalantly.

Sometimes later, Nagatoro and her friends invited Senpai to a sushi all you can eat restaurant to have a Culture Festival wrap up party with them since they sincerely intended to celebrate him and the success they had. After Gamo-chan offered Senpai a special recipe that she composed, prompting Yoshi and Sakura to improvise and do the same, feeling jealous, Nagatoro tried to make her own special dish, overdoing it and taking half of the rao for a tarako gunkan and placing in it half of the milt from a shirako gunkan to create, in her words: "a miraculous meeting between and milt that could get someone's stomach pregnant". This shocked the whole gang, prompting even Yoshi to describe it as "disgusting". While her friends scolded Nagatoro for playing with food like that, however, feeling bad for her Senpai decided to try it, finding it surprisingly "delicious".

Coming of winter
One day of the following week, Gamo-chan was chatting in the cafeteria with Senpai and her friends about a group of boys from session 1-A having been suspended for drinking alcohol at the party after the Culture Festival, although the girls criticized those boys for having been "stupid and cocky", Senpai can't help but believe they were habitual alcohol drinker too; he didn't expressed those thought out loud but they guessed it and scolded him for being rude. Then Nagatoro imagined what would have Senpai looked like drinking in a not so far off future, resulting in the group's hilarity.

During the school wide marathon, Gamo-chan and the girls approached Senpai proposing him a race. He tried to refuse saying he'd rather run at his own pace but the group try to persuade him telling that it could be like in the fable of "The Tortoise and the Hare", thus they won't let their guard down, to which he joke that they're more like cats than hares. Right at that time they saw the President overrun them all dressed in her bunny suit since cosplaying was allowed. Thus, the girls get motivated into "beating the hare" and, after Senpai wished them good luck as the President was one of her class top athlete, Nagatoro reminded him that is the tortoise who should beat the hare, thus meaning he was the one who must race her. Although he was skeptycal, the girls supported him saying they would have poured their power on him, forming a line to push one another in order to booster his speed, however after arriving a crosswalk Nagatoro and Senpai are separated from the other girls due to a traffic light, then Gamo-chan, Yoshi and Sakura told them that they should keep going and they would definitely catch up with them, which they did few minutes later while Nagatoro was carrying Senpai due to him having twisted an ankle, they help carrying the boy in a sort of human cart quoting that "a turtoise might be slow, but if you give it a booster, then it can fly". Racing all together in said formation, the gang managed to reach the President however, as she was still faster than them, Gamo-chan told Yoshi to run in front of them using her almost superhuman speed to act as a windbreak and increasing their speed, managing to easily beat the President, albeit getting disqualified by the teachers because of their formation.

First name arc
Sometime after this, when Senpai went to the first year's floor in order to give Nagatoro her smartphone after she forget it in the art club room, he saw Gamo-chan and Yoshi coming out of their class and wenting to the cafeteria for lunch. Not wanting to be caught, the boy hid in a closet inside section C.

Two days after this, Senpai became worried because he hadn't seen Nagatoro nor have received any text from her during said period so he went asking Yoshi and Gamo-chan about it, prompting the latter to reveal him that she simply got a cold but had recovered pretty quickly and would return to school the following day. Realizing how he felt, Gamo-chan asked Senpai if he knew where Nagatoro lived and, after he replied affermatively, ask him to visit her and bring her some printout in her place.

The following morning, while walking to school with Yoshi and Sakura, Gamo-chan caught Senpai and Nagatoro while they were holding their hands, smiling she immediately commented on how brave they were for doing it in public, leading an embarassed Nagatoro to quickly trying to denying it, saying to them that she was merely trying a judo move on him, without sounding believable to anyone.

Christmas
Few days later, after entering the art club room to hang out with them, Yoshi, Sakura and Gamo-chan found Nagatoro intent in choking Senpai in a submission move due to not wanting to answer his questions on the scance she just used to pose for him. While the first two simply told playfully Senpai to surrender in order to get freed from Nagatoro's move, seeing the painting Gamo-chan got quite emotional, saying heartwhelmingly to Nagatoro that "it has been a while since the last time" and asking with evident nostalgia if she wanted to give it another try. Senpai asked what they were talking about, but Nagatoro stormed out of the room saying she won't tell him.

On Christmas Eve, right after the principal speech to the students, Gamo-chan planned to invite everyone at the karaoke and got upset after both Sakura and Rabi-chan dumped her due to having other plans (respectively with a casual date, the former, and her boyfriend, the latter); thus leaving only Yoshi and Nekoba to join her. After a brief fight between the "girls with boys" and the "girls without boys", an offended Gamo-chan asked Nagatoro if she would have came to the karaoke, leading Nekoba to ask her if she and Senpai were dating or not, which caused both of them to blush. After Nagatoro denied being Senpai's girlfriend, Gamo-chan told both her and the boy to join them, however Senpai refused using an excuse and is quickly joined by Nagatoro in running off the room. Yoshi and Sakura commented gleefully on how obvious it was that they actually wanted to remain alone, to which Gamo-chan agreed - reconciling with Sakura in the process; later the girl presumably went at the karaoke alongside Nekoba and Yoshi.

Trivia

 * Before her official name was revealed in Chapter 32, the character was referenced to as "Friend A" (友達A).
 * She was the second supporting character out of Nagatoro's group of friends whose name was revealed to the readers, preceded by Yoshi and followed by Sakura.
 * Her pet name, "Gamo-chan" (ガモちゃん), literally means "little duck" or "duckling" in a cute way, albeit it's also.
 * In Chapter 1, despite being recognizable for her trademark smirk and general attire, she was depicted with far less unkempt hair and a knot tie which was never seen again afterwards.
 * A knot tie identical to the one she wore in her debut was later used for the President's uniform.
 * Since, as shown in Chapter 6 Nagatoro never manifested any kind of intrest in boys, it was likely in the first occasion in which she saw her with Senpai that Gamo-chan realized her friend's feelings for him, subsequently beginning to tease her about it.
 * Few chapters later, the first time the she visited the art club room, she already described it as Nagatoro and Senpai's "love nest".
 * In Chapter 28 it's revealed Gamo-chan and Yoshi are both members of the same club, although it's unknown which one.
 * However due to Nagatoro seemingly having acquaintances in the handicrafts club, as mentioned in Chapter 8, it could be speculated that's the one.
 * This is further implied when in Chapter 36 when Nagatoro shows up in the art club with the costume she asked her acquaintances in the club to made, they were shown to be out of the room peering at the scene.
 * Despite this, it's revealed in her character profile in the Official Fanbook that she has since left whatever club she was part of.
 * Both Gamo-chan and Nagatoro shares the love for marlowe pudding, and apparently is often the prize for the many bets and competition their friendly rivalry is composed of.
 * Gamo-chan likes, which is also one of her favourite dishes at the sushi alongside chips and yaki udon, while her favourite snacks are donuts or Kinoko no yama, and the one she dislikes is Takenoko no sato. Her drink of choice is coffee.
 * According to her character profile in the Official Fanbook her top favourite foods are the very spiced ones and she also likes junk food, while the food she hate the most is.
 * The brand of she usually drinks is the same that Nagatoro and Hachioji took at the end of their date in Issue 4 of the Nagatoro-san webcomic.
 * Like Nagatoro, she's a huge fan of horror movies.
 * Black and white are her favourite color matching.
 * Gamo-chan possess some very good culinary skills, having creating some recipes on her own with one of her dish being praised by Senpai himself, a remarkable cook on his own right. That was previously hinted in Chapter 33 when, describing how amazingly good Senpai's bento was, she used quite specific and professional terms, suggesting that she cook as an hobby or is aiming at a future culinary career.
 * Despite her "juvenile delinquent" attitude and Senpai's prejudices, it's implied Gamo-chan don't usually drink alcohol and dislike who does.
 * Also, she's seemingly more respectful of school rules and uniform than she lets on, as she doesn't wear her ear piercings at school.
 * Gamo-chan has an habit to sit in "yanki zuwari" (ヤンキー座り).
 * Her smartphone has a zebra-themed case.
 * It was suggested that Gamo-chan may have bad eyesight, and that's the reason she scowls so much; once, after encountering Senpai outside school, she has to squint to recognize him.
 * Despite usually the chapters' titles come from a line said by Nagatoro inside them, Gamo-chan is the only character who has received the same treatment, since Chapter 28, 35, 44 and 57 got their titles from lines spoken by her.
 * Thus making her the only character, outside the protagonist and her sister, to name chapters.
 * Gamo-chan bears a striking resemblance to one of the playable characters of "Jas Gear" which, interestingly, is the one Nagatoro always choose to play.
 * Gamo-chan's official measurements are: 90-60-87.
 * Due to Nagatoro not appearing in Side Story 7, Gamo-chan is the first character to having ever appeared in a chapter of some sort without the protagonist.
 * Albeit both Yoshi and Sakura soon do the same respectively in Side Story 8 and 9.
 * Being born in June 15, despite being - both physically and mentally - the most mature among the girls' clique, Gamo-chan is actually one month and thirteen days younger than Nagatoro.
 * Her astrological sign is , just like the President's.
