Hehe, since this is my favorite anime, I'll be posting something abot it. This is all about Tetsunosuke Ichimura (a real character), he would like to take revenge to the Choshuu Clan who killed his parents.
He said to himself that he need to be stronger so he might fulfill it. He was with his elder brother Tatsunasuke Ichimura, who later becomes the Shinsengumi's bookkeeper. That's maybe the reason why he choose the Shinsengumi.
Saya (fictional character)
Kitamura Suzu (fictional Character)
I think I don't need to post all of the characters :D. Well this will be all. Thank You!
