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?
It was your strength that allowed Himawari 
Ranna's true nature to come to the surface.
.فقوّتك هي التي سمحت لطبيعة هيماواري رانّا الحقيقية أن تظهر
Weil du stark warst,
Tu sei forte,
Foi a sua força que permitiu que a verdadeira
natureza de Himawari Ranna viesse à tona.
