Itsuki heads to the final battle in order to secure the future of the ones he loves. However, none of their attacks worked against the "Thirteenth Phantom", as they fall in a desperate situation. That is when the feelings of "we want to be with Itsuki" by maidens call upon a miracle!!
That's why she's acting like a girlfriend.
.لهذا تتصرّف كما لو أنّها حبيبته
Deswegen benimmt
sie sich also wie seine Ische.
Por eso actúa como su novia.
Por eso se comporta como su novia.

Вот почему она ведёт себя 
как его подружка.
