How Not to Summon a Demon Lord

In the MMORPG Cross Reverie, the feared Demon King Diablo reigns supreme, armed with the rarest gear and an unbeatable level. Behind that intimidating avatar is Takuma Sakamoto, a socially awkward shut-in who lives for the game. Everything changes when a summoning spell pulls him into another world—one that looks a lot like Cross Reverie—and he arrives wearing Diablo’s face.

He’s met by the two summoners responsible: Rem Galeu, a small Pantherian adventurer, and Shera L. Greenwood, an elf with powerful magic. Their attempt to bind him with an Enslavement Ritual goes wrong, leaving them tied to him instead. Keeping up Diablo’s domineering persona, Takuma travels with the pair as they search for a way to break the contract, all while he tries to navigate life as the “Demon King” in a very real fantasy world.
