Listen...Chopper~

A man~even if...even...encounters...a strong enemy that might kill him...can't fall... Next

Even if the opponent is... an enemy that cannot be defeated even if he dies...! Men...sometimes you absolutely can't escape...a fight...! Especially...especially when...the partner's dream...is laughed at! !
