Isekai Maou to Shoukan Shoujo no Dorei Majutsu

How Not to Summon a Demon Lord thrusts Takuma Sakamoto into the fantasy MMORPG Cross Reverie, where his character, the Demon King Diablo, stands unrivaled as the owner of the game's rarest artifacts and a player level no one else can match. In the real world, however, Takuma is a shut-in whose confidence ends when face-to-face conversation begins, and that contrast becomes impossible to ignore once he is suddenly summoned into a realm that closely resembles the game and forced to wear Diablo's fearsome appearance. There, he meets the two girls responsible for the summoning: Rem Galeu, a petite Pantherian adventurer, and Shera L. Greenwood, a busty Elf summoner. Their attempt to carry out an Enslavement Ritual backfires, turning the spell against them and binding the pair to Takuma instead. With an awkward new household, a dangerous reputation to uphold, and no easy way to break the contract, Takuma must learn to navigate this unfamiliar world while playing the role of the Demon King.
