The Miyoshi brothers have powerful regenerative capabilities.  They say that taking life is offering salvation, and in them Shungiku sees his own younger self.  Oooka, who knows the old Shungiku, is doubtful he can win the battle.
I can't imagine Koikawa-dono losing 
any more than I can Mugai-dono!
¡Pensar que Koikawa-dono pierda,
Pensar que Koikawa-dono 
no puede ganar una pelea
Eu não consigo imaginar nem o
 Koikawa-dono nem Mugai-dono, perdendo!
