Yoshi/Biography

Early life
Yoshi was born on November 23 in, , an only child; both of her grandparents lives with her and her parents. She has a pet miniature dachshund and grew up in a house in the suburbs in the same apartment building of Gamo-chan's family, leading the two to became childhood friends and thus befriending Nagatoro as well when she start to study martial arts at Gamou Fighting Gym.

After beginning to attend Kazehaya High School, Yoshi, Gamo-chan and Nagatoro 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, however she herself never had a boyfriend.

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 it is the tortoise who should beat the hare, thus meaning he was the one who must race her. Although he was skeptical, 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 tortoise 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 narrowly 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.

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 Gamo-chan looked at the picture with nostalgia asking Nagatoro if she wanted to give it another try, Yoshi and Sakura simply told playfully Senpai to surrender in order to get freed from Nagatoro's move.

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, thus a brief fight between the "girls with boys" and the "girls without boys" ensue. 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, Gamo-chan and Sakura reconciling in the process; later Yoshi went at the karaoke alongside Nekoba and Gamo-chan as the self-proclaimed "boyless group". There, while Gamo-chan performed 's "" Yoshi tried to accompanied her albeit extremely tone-deaf.

New Year
During the ski trip with their school, Nagatoro, Gamo-chan, Yoshi and Sakura's talent as they managed effortlessy to ski down the pro course greatly impressed Senpai and his classmates. Later, as Nagatoro gave the boy ski training due to his clumsiness, Yoshi, Gamo-chan and Sakura passed by and greeted them. That night, Yoshi accompaigned Gamo-chan as she asked Senpai the reason why he refused to go skiing with Nagatoro, walking away with her friend after she sweetly told the boy that the gap in skills between he and Nagatoro was not the real issues. The next morning, she watched as Senpai's classmates ask him to show what he learned for Nagatoro ("his private instructor") however, after he eventually accept, all he managed to do is fall on the snow causing the whole gang to burst out laughing.

Judo Tournament
Sometime later, with the school year nearing its end, right after discovering about the school's judo tournament Yoshi and Gamo-chan stormed into the art club room to ask Nagatoro if she wanted to join it but Senpai informed them that the girl hdan't came that day, prompting Gamo-chan to sadly state that "she still feel like that about judo", to which Senpai asked her more about it. Yoshi assisted pleased as Gano-chan explained to him about her family's gym showing him a flyer with a picture of Nagatoro on it, promoting a newcomer course. Yoshi further encouraged Senpai in going at the gym that Saturday afternoon, saying he "doesn't needed to bring a thing". Few days later the school's judo tournament began and on her first round Yoshi was penalized due to wasting time to spin around the opponent while Gamo-chan was defeated by Olympic judo team candidate Orihara, later commenting with her friend that Nagatoro would have to face Orihara in the following round, referencing their past together. Despite Orihara being friendly and telling Nagatoro she hoped to have "another exciting match" with her, the latter leaves the judo hall disconsolate much to Yoshi, Gamo-chan and Sakura's chagrin. Then, Yoshi cheered for Senpai during his match alongside Gamo-chan and Sakura, being positively surprised when the boy managed to put up a good fight and especially when Nagatoro joined them in cheering him. Even when the boy lose by points, Yoshi, Gamo-chan and Sakura commented positively how well he performed, then when Nagatoro decided to fight Orihara they all cheered for her during the match.

First date arc
After the new school year officially begun, she went picking up Gamo-chan - who have joined the judo club just like Nagatoro - after she finished practice and the two walked home together while also walking Yoshi's pet dog; after they arrived at the fork both of them overheard Senpai asking out Nagatoro for a date at the aquarium and smiled. The morning after, an overjoyed Nagatoro slightly annoyed her friends with her behavior, going as far as to force Yoshi to sing a song with her. Then, after Gamo-chan suggested to visit Senpai due to having finished club practice earlier than usual, Nagatoro refused, causing Gamo-chan to realiza that Nagatoro was "leaving the best for last"; thus fearing for Senpai's virginity, she drag Yoshi to the art club room, finding only Sunomiya due to Senpai being outside buying painting supplies, then the pair began plotting to follow the couple right in front of Sunomiya and, the following day, as Nagatoro and Senpai met at the aquarium for their date, Gamo-chan, Yoshi, Sunomiya and her cousin all followed them, the first two to "protect Senpai's virginity" while the latter pair to "protect his romance".

Yoshi followed Gamo-chan in her plan as the latter was convinced that it's too soon for Nagatoro and Senpai to take that step, so they started to take pictures of the couples "embarrassing scenes" in order to open their eyes, however both them and the Sunomiya duo, lost track of them after they entered the aquarium and, when they finally found them again, Senpai noticed teir presence and run away with Nagatoro. Gamo-chan and Yoshi tried to follow them but are stopped by the Sunomiya cousins. Later, they managed to found the pair once again on the seaside and Gamo-chan started to run toward them, however Yoshi stopped her asking her not to get in their way, thus prompting her friend to smile kindly admitting it would be more fun to simply watch them and that she would have never expect to be scolded by Yoshi. In that exact moment the Sunomiya cousins found the pair and chase them to the seaside accidentally storming on the scene just as Nagatoro and Senpai were about to hug, thus ruining the moment.

Out of anger after said event, Nagatoro started to ignore both Yoshi and Gamo-chan at school, sulking at them both; however Sakura act as the peacemaker explaining the two girls didn't mean anything bad with their action and merely felt lonely as Nagatoro spent less and less time with them. Sweetened, Nagatoro forgave her friends and the four of them went to have lunch at the art club room. There, they discovered that Sunomiya was feeding Senpai a bento she made by herself as a way to apologize for what happened the previous day. Upon hearing Sunomiya's plan to make bento for Senpai the whole week, Nagatoro got jealous and offered Senpai to prepare a bento for him the following day, which he refused, not wanting to bothering the girl. All of the girls watch Senpai cooly due to having "made a mess again"; then Gamo-chan convinced him not to be stubborn and accept Nagatoro's offer. Hearing this, Senpai told Nagatoro that he would love to have her bento if she accept to have one from him, wich she joyfully accepted.

The following morning Yoshi, alongside Gamo-chan and Sakura, has a videocall with Nagatoro while she was making bento for Senpai and supported her both when she planned to prepare a special with spicy curry in order to surprise him, than when she accidentally burned it and her sister convinced her to make salmon filled  instead to see him happy rather than surprised.

Field Trip arc
After discovering that their field trip in would have been together with the 3nd years, Nagatoro informed her friends about it and started to hope being in his same group - albeit lying that she was only interested in bullying Senpai during the trip - then Sakura told her that every 2nd year student would have been free to choosen which group join. Due to Senpai's plan being boring and revolving around visiting Buddhist art locations, Nagatoro was the first one to sign up, followed by Gamo-chan, Yoshi and Sakura, out of simpathy for the boy and mutch for the joy of the only other applicants: his two male friends. However, after joining it, they also started to change the program radically: Nagatoro added a trip to Kyoto's aquarium, Gamo-chan added a visit to the base, Sakura an excursion to  and finally Yoshi a jaunt to  in order to feed deer. Senpai tried to convince the girls that there wouldn't be enough time for everything they wanted to do in the field trip's schedule, to which they asked him to remove some of the buddhist temples from the program, prompting the boy to oppose the idea and try to explain the beauty of each statue. Despite impressed by his passion, the girls confessed that they weren't intrested in the statues, prompting Takao, one of Senpai's friend, to suggest splitting the group so everyone would be happy. Albeit a bit saddened, Senpai agreed to said proposal, causing Nagatoro to get angry and storm out of the room. Afterward, Gamo-chan promised to Senpai she would have talked to Nagatoro to made her calm down and proposed to wrap-up the issue, thus the group went back home, including Yoshi.

Later that night, the girls had a videocall and Yoshi stated she would have brough extra snacks before being warned by Sakura not to overdoing, then noticing Nagatoro was gloomy, she tried to cheer her up. During the train trip to Kyoto, Yoshi took pictures of and has a commemorative photo with the rest of the group then, due to being too excited, she - as well as the rest of the girls - got briebed by Senpai, who promised to increase the amount of free time the following day if they behave themselves; later she enjoyed the trip for the streets of the city, has lunch at the same table with Senpai, Nagatoro and Gamo-chan, visited a temple and then went back to their hotel to take a bath. Later that evening Yoshi, alongside Nagatoro and Gamo-chan, suggested to have pillow fight, however Sakura, Rabi-chan and Nekoba told them that, being all grown women, they should have "girl talk" instead.

Luckily, the couple start calling each other names in order to allow the boy finding the way once again; prompting the girls to try attack one more time, being quickly stopped by Oriaha's and Shikki's intervention, and subsequently spanked by Gamo-chan and Yoshi.
