Synopsis – The Demon King’s Retirement is Ruined by an Overpowered Noob!

Satoshi Tanaka, a burnt-out convenience store clerk, suddenly finds himself summoned to a fantasy world by a clueless goddess demanding he slay the dreaded Demon King. But there’s one tiny problem—

the Demon King is already retired, living a quiet life in the mountains and just wants to be left alone.

Unfortunately, the summoning pact can’t be undone, and Satoshi is stuck in a world that thinks he’s the legendary hero. To make things worse (or better?), he's been gifted with broken-level cheat powers that make him unbeatable—but totally unmotivated.

From running errands for the grumpy ex-Demon King, to accidentally befriending sleepy dragons, and being declared a heretic by the very church that summoned him, Satoshi’s journey goes from epic quest to chaotic misadventure.

Now hunted, hated, and hilariously OP, Satoshi must navigate political conspiracies, ancient beasts, and magical bureaucracy—all while wondering if this whole hero thing is really worth the hassle.

Action-packed. Absurdly funny. Dangerously overpowered.

This isekai isn’t about saving the world. It’s about surviving it… without doing any real work.
