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.
The Characters:
Ichimura Tetsunosuke
Ichimura Tatsunosuke
Okita Soji
Hijikata Toshizo
Yamazaki Susumu
Saito Hajime
Saya (fictional character)
Kitamura Suzu (fictional Character)
Yamanami Keisuke
I think I don't need to post all of the characters :D. Well this will be all. Thank You!
