Rokudo manages to reach the roof and attempts to stop Ranna from hurting Otohime. When he does, he's forced to confront a question he's been avoiding all along: What if she doesn't want to stop?
I have to get stronger. 
I have to win with my own strength!
!علي أن أصبح أقوى. علي الفوز بقوتي
Ich muss stark werden!
Je dois devenir fort,
quoi qu’il en coûte.
Devo diventare più forte.
Eu tenho que ficar mais forte.
