0.0000001% Demon Lord

Demon King Astrea tasked 72 worthy Demon Lords with destroying the world. Demon Lords--a title only given to those who passed Astrea’s test. Each was given powers befitting their title. Kharos, the ruler of madness and greed, was no exception. But his granted power was less than satisfactory. He received the power of "Gacha"—a luck-based ability with an abysmal pull rate. With this power, Kharos must do his best to engulf the world with madness and greed!
