I genuinely wish death on the author and anyone who enjoys this pedophilic rape fantasy, this is Kuroinu and Goblin God levels of depraved and MC the "hero" is pure fucking evil, but the way the author writes him it's clear that the author doesn't see it that way, this is clearly a Self Insert rapeharem fantasy.
He knows people from Japan are being summoned, raped, mind controlled and disposed of and he DOESN'T CARE, he even joins in on a threesome rape of a Japanese high school girl, he views every woman as meat to wet the dicks of men, his especially.
If you enjoy this, remember that rope is cheap.
