Kyouhei is a violent type of boy. Hes not good around girls since he hadnt been talking to them. Hell push anyone who gets on his way even though its a girl. Kyouhei prefer fighting `muggle style`, he mastered all of the Japanese martial art, his father had been teaching him since he was little. And hes the only one who mastered them all in the family. Kyouhei respects his father very much and his father was and is hard on him, when he was little his father used to bring him to the well and force him to break the well with his bare hand.
The relationship between the family is tight and awkward. When Kyouhei lose his temper, he would slam his own sister to the wall but thats how they get along. He had been fighting with most of his siblings when he looses his temper and hell beat them up except for Yukinojo. He dont know why he cant touch Yuki, but hes not that close with Yuki. Ranmaru (The eldest) is the closest beside Sunako.
If Kyouhei likes a girl, he will either torture them when he looses his control or not touch them at all. If the girl is a rebel-type, he might beat them up when he got a problem with her but if shes fragile then he wont touch her at all. But Kyouhei has a high expectation and hes very picky when it comes to girls since he dont believe in love in the first sight.
