Koyuki is a normal high school kid with a big problem: he can't stop himself from screaming at his crazy friends. He swears to himself each day that he'll stop, and each day he fails.
I crossed swords with him on the battlefield.
بارزتُه بالسّيف في أرض المعركة
Ich kreuzte einst mit ihm die Klingen
auf dem Schlachtfeld.
Cruzamos espadas en el campo de batalla.
Cruzamos espadas en el campo de batalla.
J’ai croisé le fer avec lui.
Il s’appelle…
Ho incrociato le spade con lui, 
sul campo di battaglia!
Cruzei espadas com ele
no campo de batalha.
Я встречался с ним на поле брани.
