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?
And you wanted this to happen, 
so don't start complaining.
.وأردت أن يحدث هذا، لذا لا تبدأ بالشكوى
Du wolltest es so,
also beschwer dich nicht.
Tú te lo buscaste,
así que no te quejes.
Tú te lo has buscado,
así que no te quejes.
Tu l’as cherché,
il ne faudra pas venir pleurer !
Hai chiesto tu questo scontro... 
Non avrai niente di cui lamentarti, immagino.
Você pediu por esta briga,
não pode reclamar!
Ты сам напросился на эту драку,
так что не жалуйся!
