It’s time for Princess Syalis to start acting like a proper hostage, so the demon king issues a decree to help change that.
I won't hurt you. Sheesh.
.لن أؤذيك
Mach ich nicht! Menschenskind!
No te voy a hacer daño. Demonios.
Je vais rien vous faire, sérieux…
Non vi farò niente. Ma tu guarda.
Não vou te machucar, fala sério.
Не буду. 
Сколько ещё повторять.
