魔族の娘たちと送る乱れた異世界生活

Hiro was sent to another world due to a mistake by a Goddess. As an apology, he was granted a cheat skill that makes him "popular with girls in the other world," but before he knew it, he was surrounded by nothing but "scary girls from the Demon King's army"!! Popular with them, seriously!? A harem comedy filled with enemy characters begins!!
