How Not to Summon a Demon Lord

Takuma Sakamoto, a skilled but socially reclusive gamer, has an unusual reputation in the MMORPG Cross Reverie due to his exceptional character, Diablo. As Diablo, he effortlessly defeats opponents, but his true self remains isolated from gaming communities. However, when a summoning spell transports him to a world resembling Cross Reverie, Takuma finds himself in Diablo's body. Two girls, Rem Galeu and Shera L. Greenwood, attempt to subjugate him using an Enslavement Ritual, but the spell unexpectedly turns them into his slaves.
