Man Yamamoto can taking a beating.
Hahaha, it's so weird seeing Yamamoto as young as that.
Choujirou looks kind of cool with the white hair + eyes... but his face looks very generic.
I really like the flashback, it very nicely shows the relationship that they share; and the mutual respect that they have for each other. It's just really sweet.
Also on "juujisai" - the "juu" part, I think, comes from the Kanji for the number 10, which looks like a "+", which is kind of like the cross on Yamamoto's head.
Man I love Yamamoto's rage face.
