Chillin' in My 30s After Getting Fired From the Demon King's Army - S01

For more than 30 years, Dariel served loyally in the Demon King's army, raised by Granbarza, one of the Four Heavenly Generals. But since Dariel has no magical potential at all, Granbarza's son Bashbarza sees him as nothing but a disgrace, and fires him right after taking over his father's position as general. With no home and no job, Dariel wanders the forests, where he comes across a human girl named Malika fleeing from a monster. After he steps in to help her, she invites him to stay in her village in return. There, he learns that the reason he has zero aptitude for magic as a demon is that he is actually human. But Dariel is no ordinary human. With potential that far surpasses even heroes, he may soon be drawn into the endless conflict between humans and demons, fighting against the race he once called allies.
