My Magic Works Only When I Talk Nonsense

When an ordinary office worker wakes up in a fantasy world, he expects cheat skills or divine blessings. Instead, he discovers the most absurd gift: his magic only works when he spouts complete nonsense.
Want fireballs? He has to claim volcanoes are powered by off-key opera. Want lightning? He insists mismatched socks attract thunder. The more ridiculous the lie, the stronger the spell.
Armed with sarcasm and shameless imagination, he turns deadly battles into comedy sketches—yet somehow keeps winning. As kingdoms fall and the Demon Lord rises, the fate of the world may depend on the biggest clown of them all.
