Hana Sunomiya/Biography

Early life
Hana was born in, , into the Sunomiya family and has an older cousin, Sana who looks almost identical to her. Sharing her cousin's passion for arts, during her middle school years, she joined the school's art club, meeting Naoto Hachiouji and developing a great respect for him.

Beginning high school
After she began attending Kazehaya High School, the girl immediately went to the art club room, accidentally interrupting a conversation between Senpai and Nagatoro and asking to join the club. After Senpai introduced the two girls to one another, Nagatoro gets unnerved to be introduced only by her surname, grade, and sometimes harsh manners, while Sunomiya, having heard the word "kiss" while in the hallway and seeing how they interacted with one another, asked if they were dating, which Senpai quickly denied much to Nagatoro's chagrin; then the boy explained to Sunomiya that sometimes Nagatoro modeled for him the previous year, but now she won't have that much time as she has club activity. Hearing this, Sunomiya realized that the club doesn't have any other members and thus she and Senpai would have been alone in the club room; despite Nagatoro trying to have the girl change her mind from joining the club, telling her she would have caught Senpai's wriggly motions, Sunomiya stated to be able to find beauty in all eccentric things. Right at that moment, Gamo-chan entered the room to go to judo practice with Nagatoro and, seeing her friend saddened, teased her, asking Senpai if he was "switching girls". This embarrassed him, leading him to explain to her that he and Nagatoro were simply trying their best separately. Then Sunomiya reassured Nagatoro to leave Senpai in her care and stripped saying she was ready to pose for him in the nude rather than in a simple swimsuit. Outraged, Nagatoro told Sunomiya to put her clothes on again, commenting that she's just like the former President, to which Senpai pointed out that she's the President's cousin. Later, Senpai showed his recent paintings to Sunomiya and she told him they seemed more colorful than the ones he did in middle school, guessing it was because of his new model, which she described as a goddess. The boy denied it stating Nagatoro was more like a demon, to which Sunomiya asked why he did so many paintings of her if that was the case, which led the boy to admit he enjoyed painting Nagatoro. Understanding the situation, Sunomiya quoted her cousin who said "Love is something one must seek out and take", and thus told Senpai that he must ask out Nagatoro on a date.

First date arc
However, the boy quickly repelled her suggestion, stating that Nagatoro would have never accepted to go on a date with him, and all it would have resulted from that would have been the boy getting bullied again by her. She then apologized for not being able to advise him better due to her inexperience regarding love. Senpai then apologized in turn for troubling her about this, to which she answered that she didn't mind. Later, as they were leaving the school, Senpai noticed it was getting dark and asked Sunomiya if she had informed her family, to which she replied that someone would be picking her up; right at that moment, her older cousin appeared, riding a motorbike. The elder Sunomiya greeted the boy, asking him if he was alright because she could sense something was troubling him. The younger Sunomiya quickly explained the situation to her cousin despite Senpai's embarrassment, thus prompting the older cousin to tell Senpai he should follow his heart. The cousins then drove away and left Senpai alone with his thoughts, with the younger Sunomiya riding in the sidecar of her cousin's motorbike.

The morning after, Senpai thanked Sunomiya for the advice she gave to him and told her about having invited Nagatoro to the aquarium, leading the latter to happily congratulate him; then the boy left the art club room early to go buy painting supplies, leaving Sunomiya alone when Gamo-chan and Yoshi went there looking for him. At first, the girl thought they were just a pair of delinquents, but after they introduced themselves as friends of Senpai and Nagatoro, she revealed to them that he got out earlier. Then, she heard the pair plotting and understood it as them trying to get in the way of the date itself; therefore, 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".

The Sunomiya cousins tailed Gamo-chan and Yoshi to prevent them from doing anything during Senpai and Nagatoro's date; however, all of them lost track of the couple after they entered the aquarium and, when they finally found them again, Senpai noticed their presence and ran away with Nagatoro. Gamo-chan and Yoshi tried to follow them but are stopped by the Sunomiya cousins; however they managed to escape them, so the two cousins eventually found both girls at the seaside and chased them, accidentally storming on the scene just as Nagatoro and Senpai were about to hug, thus ruining the moment.

The following day Sunomiya brought Senpai a bento she made by herself and fed him as a way to apologize for what happened on his date with Nagatoro, and they were caught by the girls. 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, however, the boy refused, stating that she would have morning training the following day and it would be too much trouble if she would have spent the evening cooking for him. Disheartened, Nagatoro agreed, while all of the girls watch Senpai coolly 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 would accept to have one from him, which she joyfully accepted. The following morning, Sunomiya and her cousin both have a video call with Senpai and suggested he treat making his bento like a food battle with Nagatoro, but the boy refused.

The following day, after Senpai had lunch with Nagatoro, Sunomiya came into the room and advised the boy to "keep up his guard" as he was "swimming into the open ocean" and thus "water filled with sharks".

Field Trip arc
After Senpai has the first meeting about the schedule of the field trip he was appointed to lead and Sunomiya found him somewhat sad in the art club room, she asked him what happened and he explained the problem he had in making everyone happy with the program, causing the girl to angrily state that there was no way to reach an understanding with "those fiendish spawns of hell", however, Senpai replied that splitting was the only way and Sakura, who came back and overheard them, calmly explained to him that the real reason because Nagatoro got mad was that she was looking forward to enjoying the trip with him. After hearing this, Senpai asked Sunomiya to help him make a simplified version of the trip's program, which she eagerly accepted.

When the boy came back from the trip, Sunomiya greeted him and received some he bought her as a souvenir. The girl promptly asked him if there had been any progress with his romance, leading Senpai to admit that he finally realized his feelings, to which she gladly replied that he needed to confess to Nagatoro. A few days later, hearing from Senpai that he planned to confess to Nagatoro only after becoming "worthy", Sunomiya pointed out that by then, feeling neglected, the girl could have fallen for another guy; however seeing the boy frightened at the idea, she then decided to "instruct him in the techniques of love", using romance manga due to her own lack of first-hand experience, eventually suggesting him to grab Nagatoro's hand in order to see if their feelings were mutual.

Nude modeling arc
The day after Senpai went to a class trial for Kainan Art Preparation School, she was in the art club with him painting still life when her older cousin stormed in (under Nagatoro's request), reassuring him regarding his art skills and offering to teach him a secret technique to overcome anxiety while drawing; the boy eagerly accepted, to which she revealed said method is "repeated exposure to the shocks of overwhelming art" by doing nude sketching, thus stripping naked; shocking everyone else even Sunomiya. Then, as Nagatoro stormed in, scolding her cousin for stripping and the latter explaining that nudity is nothing to be ashamed of and that nude painting is one of the pillars of arts she, alongside Senpai, agreed with her. Thus, she watched as the disagreement between the two girls escalated until they decided to have a nude modeling challenge, later leaving the school alongside her cousin, wishing both Senpai and Nagatoro good luck.

Training camp arc
A few days later, after complimenting him for wanting to do both the cram school and the art club, Sunomiya asked Senpai about his plan to confess to Nagatoro, to which he ultimately stated that he wanted to do after achieving a goal of some sort. Then, noticing he will have the mock exam at the end of the month, she suggested for him to aim at gaining first place in it, to which he ultimately agreed. Right at that moment, the former President stormed in, taking her clothes off and claiming that she wanted to help him by holding a special training camp for him in the following day. Hearing that, Sunomiya started to strip as well, claiming that she would help him too; however, after Nagatoro came into the room, the trio explained what was happening and that they were going to have a training camp. After Senpai accepted the Sunomiya girls' offer in order to improve himself, Nagatoro blushed happily but claimed that seeing him getting so mature made her feel a little lonely and walked out of the room causing the boy to chase her while she and her cousin commented that judo and art clubs would have had training camps in the same days, calling it a sign of destiny.

On the first day of the training camp, her cousin arranged for them to have it together with the judo club, so they went to the same place as them and Sunomiya introduces herself to the judo club members, before watching Nagatoro and Senpai happily greet one another. Later on the group travelled to the, where they started their training camp in a meeting room rented by the former President, who explained that the majority of private universities split practical and theorical in 6:4 for their entrance exames, thus having Senpai concentrating on study while Sunomiya on sketches. At the end of the first day of training camp, while exiting the training room's building, Sunomiya was approached by Gamo-chan, who asked for her help due to having in mind something regarding "love". After Gamo-chan explained to her that Nagatoro had closed herself off from the world to run in circle around the town in a sort of spartan self-training, and told her their plan of making the girl interact with Senpai in order to stop, Sunomiya allied with them - despite some minor skepticism - and, while Yoshi, Sakura and Gamo-chan monitored Nagatoro's position, she kept Senpai into the meeting room in order to have him exiting the building in the right time. Gamo-chan's plan seemed to work until, at the last time, Taiga and Misaki spot Senpai and asked him to join them in playing Uno and have a little chat, however the boy ultimately refused after sensing Nagatoro outside and instead go to the with her. Later, while celebrating their plan success, Sunomiya, Gamo-chan, Yoshi and Sakura realized that the onsen is actually mixed-gender. A discussion ensue if Nagatoro and Senpai would have "gone wild" or not, even considering to go checking on them, before Gamo-chan stated it would be inapropriate and to let them their privacy and freedom to act on their own free will; however right at that moment Misaki and Taiga - having overheard them - entered the room menacingly asking what were they saying. Then, she assisted at the sparring matches between Taiga and Gamo-chan, resulting in the latter eventually scoring a point and convincing the Nagatoro siblings not to get in the way of Senpai and Nagatoro.

The following day, seeing Senpai happy she stated to be glad everything went fine and jokingly called him "gross" quoting Nagatoro; then as her cousin invited Senpai to have lunch with them, she smiled happily after the boy decided to go with Nagatoro instead.

On the last day of training camp, she complimented Senpai for having pass their simulated mock exam alongside her cousin and, later, after the responsibles officially annunced the end of training camp, she is happy to have been given free time for the rest of the day to go enjoying the city. However, shortly after, she noticed that Gamo-chan, Sakura and Yoshi were planning to follow Nagatoro and Senpai on their date, thus getting angry and informing her cousing, however she calm down after Taiga intervened and joined them on going sailing.

Kainan's Big Four
After the training camp, she made friend with Gamo-chan and the two happily began to share gossip on the relationship between Nagatoro and Senpai to one another.
