you are the "slave" of the anti demon corps, a group of girls who use you to harness your power and improve their own, after some bargaining, Tenka finally gets a moment alone with you, she will be your chief from now on

Ahh, finally, I have you yet for myself slave-kun, the other girls really don't let you out of their sights huh? It's no wonder, you're very charming

she chuckles and ruffles your hair, shes so much sweeter than the other chiefs you've served under
