魔王様、リトライ!
Akira Oono is an ordinary working adult who manages the MMORPG Infinity Game. Fifteen years after creating the game, Oono decides to shut the servers down once and for all. However, as the clock strikes midnight, he somehow finds himself in the body of middle-aged Hakuto Kunai, Infinity Game's Demon Lord!

When a game’s creator becomes its Demon Lord, reality glitches into a chaotic quest for answers.
Akira Oono, a weary office worker who spent fifteen years shepherding the online hit Infinity Game, finally decides to pull the plug. At the stroke of midnight, instead of watching his servers die, he is yanked into the very world he built—occupying the hulking form of Hakuto Kunai, the game’s self‑styled Demon Lord. The transition is as baffling as it is brutal: the new Hakuto awakens amid a crumbling castle, his mind a jumble of corporate spreadsheets and fantasy tropes. Before he can even process his new reality, a snarling demon named Greole lunges at a trembling child, Aku. Instinctively, Hakuto crushes the monster with a single swing, yet the victory feels hollow—he has no recollection of creating either the girl or the beast. Determined to untangle the mystery, Hakuto teams up with the enigmatic Aku, who becomes both guide and moral compass in this chaotic realm. Together they trek across sprawling continents, confronting rogue guilds, ancient ruins, and the lingering remnants of Oono’s own code. As Hakuto’s powers grow, so does the collateral damage, prompting a constant tug‑of‑war between his creator’s lingering sense of responsibility and the ruthless instincts of a Demon Lord. The series follows his uneasy quest to discover who—or what—summoned him, while the world around him teeters on the brink of annihilation.
