Chidaruma
Chidaruma is the most powerful devil in hell as well as leader of the devils. He is the devil that discovered En as a child and brought him back to the human world.
Personality
Chidaruma is one of the sillier characters in the series, often carrying out ridiculous and frivolous things merely to stifle his boredom. Some examples of his past antics would be dropping bird poop he collected on various magic users, messing around with En and the growth of his mushrooms, and even annoying some of the other devils. He sleeps quite often, regardless of the lack of need to sleep, merely because he likes doing it, going so far as to rip off his horns and tongue just to make himself sleep even more comfortably.
