The series follows Sakamoto Takuma, an elite but socially inept gamer who is so powerful in the MMORPG Cross Reverie that other players call him the "Demon Lord". One day, he is suddenly summoned to a fantasy world that mirrors the game, complete with his in-game appearance and overwhelming abilities. Before he can process this, the two girls who summoned him—Rem Galleu, a dark elf, and Shera L. Greenwood, a high elf—attempt to use a slave-binding spell on him, believing him to be a summoned beast. However, the spell backfires, enslaving them to him instead. Despite his immense power, Takuma is awkward and has poor social skills. To navigate this new world and cope with his circumstances, he decides to continue playing the role of the Demon Lord Diablo while trying to find a way to break the slave spell. The story blends action, adventure, comedy, and harem elements, following Diablo as he uses his strength to protect his "slaves" and inspire the world, often while grappling with his own insecurities and the challenges of his new life.
