Demon Girls and My Decadent Isekai Life

Synopsis

Hiro Takanashi is transported to another world due to a mistake by the goddess. As an apology, he is granted the cheat skill of "being popular with girls of the other world," but before he knows it, he's surrounded only by "scary female officers of the Demon King’s army"!! Popular? With these girls, of all people!? A harem comedy filled with enemy characters begins!! (Source: Akita Shoten, translated)
