Yōsuke Hirata

Yōsuke Hirata is one of the top students in class 1-D and a member of the Soccer Club. His excellent grades are worthy of being in an upper class; however he ended up in D-Class for reasons yet to be explained. He is situated on the leftmost seat in the second row, next to where his 'girlfriend', Kei Karuizawa is seated.

Appearance
Yōsuke is a young man of average height with blonde hair and brown eyes. He is often seen wearing the standard school uniform but when outside of school he wore a striped shirt when he and Kei ran into Suzune over summer break.

Personality
Yosuke is very friendly around people, and rarely gets mad. His warm nature has led to the majority of the class to recognize him as a class representative. He obtained the trust of the class while attracting the attention of several girls, most notably Kei Karuizawa. He accepted a relationship with her to help prevent any sort of bullying that might come to Kei, as she was afraid of what happened when she was in middle school repeating again. This goal seems to have been achieved.

Hirata has a trusting side to him, as shown when he covered for Kiyotaka Ayanokōji after he found Karuizawa's underwear on him, believing his explanation of not being the thief as he wouldn't do such a thing, despite not knowing him well or having evidence to prove otherwise.

He has an adept leadership ability as shown in the survival test where he managed to get everyone to come to common ground after a brief argument over provision and points.

Despite all the positive qualities he displays in his class, he can be quite shaken up, as shown when he became horrified after the survival book was burned and was so stunned that he couldn't understand what caused this to happened. He only snapped out of it when he heard Ayanokōji stating his class was asking for help as he gave them orders.

Physical Abilities
Yōsuke hasn't been shown to do much in terms of physical strength or brute force, but he has mentioned that he plays every sport imaginable and tried out for the school soccer club.

Academic Abilities
Yōsuke has demonstrated decent grades good enough to get him into the upper classes, but currently unknown factors led to him being put in Class D.

Intellectual Abilities
Yōsuke has demonstrated that he possesses quite a talent in leading others, becoming one of Class D's central figures and class representatives. He further proved this going into the special island survival test, using sound strategies to rack up as much points as possible for his class. It is shown that when things go wrong he is not above cracking under the pressure, but can quickly recover when people assure him that he is needed to be calm and collected.

Plot
In the anime's debut, Yōsuke, like the other first years, listened in to the speech given by Manabu Horikita, the Student Council President welcoming them to the Advanced Nurturing High School. While waiting for their teacher to begin the classes that day, he asked everyone in class 1-D to introduce themselves, starting off stating how he played every sport imaginable and wanting to apply for the soccer club, while also hoping to get along with everyone else.

Other people followed his lead, introducing themselves in turn until Ken Sudō cut in with his remarks of how childish it was before Sae Chabashira walked in and started class. Of course like the rest of his class he was surprised at their initial 100,000 points, but was of course confused why they didn't receive any next month, prompting Sae to give out a further explanation of the points system and why D-class is seen as being D-Class.

At the start of Episode 2 of the anime Yōsuke was seen hanging with his class at the pool, getting especially close with Kei Karuizawa.

For most episodes after that he is often seen in the background or associating with Kei as shown they were seen together talking to Suzune Horikita before Kei drags him away.

During the school cruise, Yōsuke meets Kiyotaka on the cruise and tries to make conversation before revealing needed his ship in talking to Suzune to get her to speak to him as he needed her for representative matters.

Along with his class, Yōsuke and his class were told the purpose of the cruise was to ready them for a survival test which would last for a week. Once the ship stopped at a Deserted Island, Yosuke together with his class 1-D classmates, discussing how to moderately use their S-Points for their mutual benefit.

When Kei's underwear is stolen, Yōsuke searches the boys for them and when searching Kiyotaka, he finds the underwear on him (after Ike placed them on him). Not wanting any further problems, he covers for him, to the latter's surprise. In the evening, Kiyotaka questioned his covering for him as Yōsuke reveals he knew it was the underwear and asks if he was the one who did but Kiyotaka denies it as Yōsuke accepts knowing he wouldn't do such a thing.

The next day, the girls want the boys to separate from them though Yōsuke tries to dissuade them he agrees with their choice. Since he is well known for being kind and trusting, the girls put him on guard duty as Suzune stepped in stating since Yōsuke is still a boy he needed to be watched as well. The girls acknowledged her point but had no idea of who to pick as most of the boys were lecherous as Suzune nominated Kiyotaka as another guard to work and watch Yōsuke. This decision was accepted by Yōsuke who tried to lift the spirits of Kiyotaka after he complained about being a last resort.

When the camp faces a problem after the survival book is burned, Yōsuke is left in disbelief as he breaks down unable to process why misfortune is befalling the camp as he left deaf to the pleas of his class. He is snapped out of it by Kiyotaka and orders his class into shelter to brace the storm going on.

Before the test ended, Kiyotaka gave Yōsuke the news of Ibuki and Suzune withdrawing as he sunk into despair at the class failing. Kiyotaka soon gave Yōsuke a paper holding the names of the other class leaders while giving Suzune credit. His actions allowed the class to succeed and relieved Yōsuke who had no idea of Kiyotaka's role.
