Level 0 Demon King Becomes an Adventurer in Another World #005

The strongest demon king comes to power as an adventurer in another world in this action isekai manga!

Ishuto was the strongest demon king in the Dark Continent until he was defeated by the heroes. But instead of dying, he reincarnated into another world as a young man, while still keeping his powers. “I will start from scratch in this world and this time it’ll be mine!”. The elite adventurer Airis was charmed by Ishuto’s strength and became his guardian so he could enter the adventurer training school, but due to his otherworldly powers, he graduated the very first day, receiving the unprecedented title of “level 0”. He’s a maverick with demon king powers that no one can rival!
