Koukin Shuuyu

Koukin Shuuyu is a captain of Nanyo Academy. He is an A Rank Fighter, with a strong penchant for leadership. He primarily serves as a strategist, though occasionally will step up to fill the role of field commander if needed.

Appearance
Koukin is a boy of average height with a frail build. He has messy black hair which hangs down to his shoulders. He is fairly handsome, though not as much as some of the other Nanyo captains, often leading him to be overlooked.

Personality
Koukin is a shy, reserved person. He tends to avoid being dragged into fights, and prefers to adopt a more cautious, wait and see approach to his problems. He can be coaxed out of this mentality by a serious or immediate threat. When this happens, he is much more decisive, and will strike with as much force as necessary to mitigate the threat.

Sonsaku Hakafu
Koukin and Hakafu are cousins. Since they were little, Koukin has been instructed to protect Hakafu, a duty which he takes seriously. They live together in Koukin's house, along with Hakafu's mother. Koukin is very fond of Hakafu, despite her insistence on teasing him, and ignoring him when he tries to keep her from engaging in stupid activities.

Shimei Ryomou
Koukin and Ryomou get along rather well, despite a rocky start. They originally struggled to see eye to eye, but as Hakafu won Ryomou over, they also started to get closer, and became friends as a result. Koukin has a lot of respect of Ryomou's abilities, as well as faith in her to execute almost any plan that the captains concoct.

Gakushuu
Koukin and Gakushuu are good friends. They had a rocky start with the way that Hakafu picked a fight with Gakushuu, but became close as it became apparent Hakafu would assume leadership, and Gakushuu came to respect her abilities, while needing someone to help keep her under control. Since Hakafu did take leadership their friendship has only grown, as has the necessity of their parternship.

Hiroki Akiyama
Koukin is mildly suspicious of Hiroki. They interact regularly, as Hiroki comes to him for instructions quite often. They get along with each other well, but Koukin finds Hiroki's tendency to go around Hakafu a bit unsettling, and worries that he's scheming something.

Hitomi Yamaguchi
Koukin has mixed feelings towards Hitomi. He gets dragged into social gatherings with her often enough that he is familiar with her presence, and has come to enjoy spending time with her. Despite this, he's not entirely sure what to make of her. He's aware of her manipulative nature, but his gut tells him she's trustworthy.This conflict makes it difficult for him to work out how to treat her.

Shun Mori
Koukin has a decent amount of respect for Shun as a fighter. He appreciates the value of his fighting style, and personally headhunted him to be a captain. He doesn't interact with Shun much outside of work however, as Shun is a bit too awkward for his tastes.

Hanae Nakano
Koukin gets along well with Hanae. He appreciates how simple she is to understand and work with, and the reliability with which she performs when given tasks within her capabilities.
