Takuma was just another awkward gamer, but a twist of fate sees him summoned to another world–in the body of a demon lord! And no one’s more terrified of the prospect than Takuma himself. He may have power, but he’s in way over his head. So he decides to pretend to be the monster he looks like, and accidentally winds up with a pair of gorgeous slaves: a voluptuous elf and cat girl. It’s not what any of them wanted, but they’ll have to figure out how to work together if they want to survive! (Source: Seven Seas Entertainment)
