Sexual Preferences: Straight
Secret Fetishes: As many teenagers unexperienced in love he has thoughts that goes between big breasted girls to find “true love”. He also likes older girls, kind girls, sportive girls, struggling and dominate his partner.
Appearance: he is 5’6’’, he prefers to wear the black uniform of the Japanese public schools, if he is not in the school wearing jeans and hooded jackets. Coming from a cold region much of his clothes might seem inappropriate for the weather of the city at first. He needs reading glasses
Personality:Kensuke is the elder son of the noble Minamoto family, so he is expected to accomplish with the high standards of traditional Japanese families in studies, manners and also in the martial art his family has practiced since the Sengoku Age, Jujutsu or Jiujitsu, managing to won the regional middle school tournament twice.
He is unexperienced in matter of love due to his father had forbid him having a girlfriend since he is already engaged with a girl since childhood. Because of it he is quite a tsundere, but considering his past, he might become a bit of yandere if he is in love or think he is. As he couldn't have any girlfriend, he found other ways to deal with his libido, while practising jujutsu, he likes to touch and struggle with girls, and he enjoys while they moan or yell their submissions. He knows it's weird and try to repress those sensations.
Besides, as his mother died when he was a kid, he likes to "punish" women physically or verbally, again he represses it; also his mother's absence causes he likes older and caring girls.
He is very self-controlled, being polite but distant as is expected of a descendant of a noble family. But he is not a rich big-head, for the reduced number of people who know him well, specially his sister, he is a good person who really cares for those who have gained his sympathy, expressing it through actions rather than words. However, in some occassions, after surpassing his breaking point, he can have burst of anger and violence.
Other detail is that his family, like the Republicans, has taught him to politely dislike foreigners and homosexuals.
He spent much of his life in Hokkaido, the Northern island of Japan, therefore at his arrival he was not only new in the academy but also in the city, so everything is kind of new for him.
