Yoshi

"Hilarious!"

- Yoshi's catchphrase

Yoshi (ヨッシー) is a supporting character of the Don't Toy With Me, Miss Nagatoro manga series. She is a first year high school student and one of Nagatoro's friend. Yoshi is a simple-minded and somewhat childlike air-headed girl as well as a sort of sidekick within the 'cool kids' clique, which Gamo-chan, Sakura and Nagatoro herself are part of. She usually imitate or repeat her friends gestures or last words and follows around Gamo-chan, helping whatever schemes she has in mind, especially teasing Senpai.

Her surname is currently unknown.

Appearance
Yoshi is an attractive, average stature, first year high schooler with long, dirty-blonde hair pinned back in tight pigtails, with a distinctive curly cowlick right on the top of her head. She has milky skin - only slightly darker than Senpai's -, and large, somewhat absent-looking hazel eyes. Both of her lobes are pierced, and she always wears stud pearl-like earrings. She was the second tallest out of Nagatoro friends, until Sakura reached her height, albeit they are both several inches below Gamo-chan; however at the beginning of the story Yoshi was just a couple of inches taller than Nagatoro and had a very modest bust size, yet during the summer she underwent some puberty changes that at first made her taller and then turned her physique from skinny to curvy - with a slight hint of chubbyness - earning her the biggest bosom among her clique, though this has some consequences as she often appear slightly hunched over due to the weight, albeit she remained impressively athletic. Yoshi usually sports a vacant open-mouthed cat smile that signifies her lack of intelligence, and her pigtails fly up whenever she's surprised or excited.

She typically wears her school uniform consisting of a white button up shirt (with loose sleeves and the collar never buttoned) and a navy blue skirt completed with a pair of sneakers and light 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. She is also always seen wearing a spare hair tie as a bracelet on her right wrist.

When not at school her wardrobe consists of t-shirt, shorts and sneakers/sandals, meaning, she's not one to groom herself.

Personality
Yoshi appear as an energetic, enthusiastic and willing individual with a childlike and simple-minded attitude, she's prone to talk in a loud, spontaneous, manner and has an habit to mimic other character's actions as well as repeating the last word they said like a parrot. Generally speaking, she's seen as only a tag along to Gamo-chan and doesn't seem to have a personality of her own; however her antics are less mischievous than that of her friends and she's much more of an openly sweet person who doesn't enjoy inflict pain or mock the others but rather does what the other girls do due to. Her loyalty and affection toward her friends is such that she is thrown into panic and confusion whenever Gamo-chan and Nagatoro butt heads because she's equally close to both of them, sometimes she even try to be the peacemaker between the two.

Described as "a natural airhead", Yoshi display an evident lack of intelligence, is not particularly bright and always absent-minded; often needing to have explained even the most obvious things, failing in understand something even if repeated more than once or even, as shown in an extra sketch of Volume 4, getting lost very frequently in crowded places. She is ranked as the lowest among her clique for academic skills. Her character profile refer to her as a "" implying she could actually have some kind of intellectual disability. Regardless of this, many of her quirks seems to came for a deep insecurity as whenever asked what she wanted to do, Yoshi defer to Gamo-chan or Nagatoro for guidance, further proving her lack of confidence, she's also very fearful and easily impressionable, getting scared every time Nagatoro scold her, when they confronted the President and even admitting to be afraid of crossing the road when the traffic light is blinky.

She is very popular among boys, even more than Gamo-chan and Nagatoro, and is often seen flirting with them or being approached by guys with flirting intentions. Due to this, Yoshi often try to act as the matchmaker for her friends, planning various double dates. She is more socially-driven than any of her friends.

Her hidden depths are her love for animals, dogs in particular, and being extremely physically affectionate, tending to extern her affections to others with frequent hugs and caresses which, combined with a very low sense of personal space, prompt her to have an obsession to touch Senpai's hair due to how fluffy they are. Also she is implied to be a closet, being a fan of ', managing to identify the Fusion Dance from ', and often mentioning genre movie actors such as or Junji Inagawa, beside actually really apreciating Senpai's manga.

She is also extremely athletic, loves the beach, and is likely the most physically performing out of all her friends, having proven to be capable of almost inhuman feats such as possessing enough strength to constrict someone with one hand, or running at such an amazing speed to act as a windbreak. Also, she has an impressive eyesight and remarkable observation skills.

Yoshi is the most gluttonous of the girls' group, and ate everything regardless of it's unhealthiness. In most of the background scenes depicting her she is shown eating something.

Yoshi usually refer to Senpai calling him "Sense" (センセ), as short for "Manga no Sensei" (漫画の先生).

Early life
Yoshi was born in, no information about her family are given. She grew up in a house in the suburbs right in the same neighborhood of Nagatoro and has a pet miniature dachshund.

Yoshi made friend with Nagatoro and Gamo-chan 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.

Being very popular among boys, since they reach teenhood Yoshi often tried to be the matchmaker for her friends, without any results.

She joined the same club as Gamo-chan but it's unclear which one it is.

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, though Yoshi actually liked it a lot. 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, including Yoshi, to go while Nagatoro choose to stay there.

Sometime after this, Yoshi organized a get together with two boys to introduce them to Nagatoro, hoping to find her a boyfriend, however her friend cannot bring herself to like any of them, even saying to Yoshi that "boys are boring" and scolding her for having do something similar again despite she asked her not to doing it more than once.

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-cnhan and Yoshi burst out laughing at the futility of his statement and apologizing to him, admitting he was a very funny guy.

Yoshi followed Gamo-chan after the latter, suspicious that Nagatoro actually really has feelings for the boy, visited the art club room together finding Senpai alone since Nagatoro has momentarily exited to borrow a comb in order to cut his hair. At first she simply looked around, however after Gamo-chan 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, Gamo-chan 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 and 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 caughting them, Gamo-chan became sure of her friend's feelings toward Senpai and, from that moment on, both she and Yoshi started to teasing him instead of bullying.

Summer break
During the summer break Yoshi, Gamo-chan and Nagatoro decided to go to the beach and the latter invited Senpai too. The afternoon in which the group met, being surprised that he joined them, 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 and Nagatoro had swimming competition arbitrated by Yoshi. Then, due to Nagatoro feeling bad for Senpai all alone under their parasol, she 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 Yoshi and Gamo-chan 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, since Nagatoro was forced to go to school due to having a special club practice, Yoshi went there only with Gamo-chan. Surprised to found Senpai was at the festival too, she approached him and, after her friend correctly guessed that he marched all the way there holding to the hope to meet Nagatoro, she complimented him for having been brave, despite the boy denied it embarrassed. Then the two informed him about why Nagatoro couldn't come to the festival and, since he then tried to leave, they caught him with a dog collar and asked him to accompany them around the festival. Then Gamo-chan 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. Gamo-chan's plan to made Nagatoro jealous, thus prompting her to came, worked and Nagatoro run from the swimmin 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 Gamo-chan, after playing some other games, Nagatoro and Senpai managed to win a big squiddy peluches and, knowing Yoshi collected them, her friend 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, Yoshi sat at the gazebo in the park close to Nagatoro's home chatting with Gamo-chan, Sakura and Nagatoro herself when they were approached by a couple of boys who started to hitting on them. 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, being immediately joined by the rest of her friends, who then 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 Gamo-chan 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. Then, a splinter inside the wooden box he was carrying went into Senpai's finger and Sakura offered to yank it off for him, while Yoshi and Gamo-chan 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, Yoshi, Gamo-chan, Sakura and Nagatoro watch from their classroom window as the second year students were having a marathon, immediately she spotted Senpai and the gang marveled at how poorly he was performing, since he was way behind everyone else.

After the school cafeteria where Yoshi 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 caused by Yoshi, who after having found a bare-breasted female bust asked if it counted as lewd, he sneaked inside 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, 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, Yoshi 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, Gamo-chan helped resolve the stalemate, revealing 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 Yoshi watched amused as her friend ate Senpai's chicken and has a "foodgasm" just like she and Gamo-chan 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 that real feeling could blossom between them, 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.

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 frantically 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 Yoshi and Gamo-chan 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, Yoshi and Gamo-chan 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 Yoshi explaining she would help Gamo-chan in preparing 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 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 a frightened expression, Yoshi 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 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. That made Yoshi get panicked, knowing Nagatoro would have been offended by it.

After Nagatoro sulk at Gamo-chan for having dissed her, Yoshi assisted the latter in explaining why it wasn't her intention to offend her, then Senpai claimed that both Nagatoro and the President are charming in their own way, finally prompting Gamo-chan to apologize to her friend, eventually easing Yoshi too. 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 embarrassing 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 grup at the cafeteria, saying 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. This seem to be the moment in which even Yoshi had the confirmation of the feelings between the two. Then, the girls sneak a peek at the President's work and, after seeing it, they 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, Yoshi thrown him out of the room telling they would do their best to ready her up. Then the girls 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 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 saying that Yoshi and Sakura could work harder to fill the void until she came back; however after Sakura revealed she had actually sneaked away to take some ice cream leaving one of the boy who adore her as a substitute in her mascot costume, Yoshi get mad and started to beat him alongside Gamo-chan.

After 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 exulted with Yoshi and Sakura. Then, 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, when Nagatoro said she would have taken a little walk around too, all of her friends cheerfully realized she was actually planning to go to Senpai to invite him at the live concert and wished her "good luck".

The following day, Yoshi and Gamo-chan 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, Yoshi 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, Yoshi 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 since Yoshi was too afraid to cross the road. Then Yoshi, Gamo-chan 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 Gamo-chan and Sakura, Yoshi caught Senpai and Nagatoro while they were holding their hands, she 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, including the usually clueless Yoshi.
