Koma

Koma is a demon that lived in a shrine that Isafuyu introduces to Aoi.

Appearance
In Koma's first appearance, he looked like a small bipedal dog with curly hair and a comical face. However, when in battle Koma changes into a more beastly form, looking like a cross between a lion and a dog and standing twice as tall as a human.

Personality
Koma is very perverted and will ask girls their three sizes, he even asked Aoi for her panties in exchange for his assistance. Even when he is in battle he will say lecherous remarks about any girl in the vicinity. He is constantly teasing Aoi which usually earns him a harsh beating from her. He believes if he were to be killed by a cute girl, that would be the ideal way to go.

Akumano Academy Arc
Koma is a demon of the Shicarion Family, which moved to the human world long ago. His people are called purifying gods and have statues dedicated to them at shrines. Koma lived in a shrine on the mountain near the Mapputatsu shrine and would lend his power to local priests for exorcisms.

He assisted Isafuyu with her exorcisms, but only if she would tell him her three sizes. After Isafuyu introduced him to Aoi, so that she might be able to fight demons, he tried this on her and she beat him into submission. Koma struck a deal with her and became her partner. He helps her defeat Agiel in Akumano Academy and accompanies Aoi, Oga, and Beel to Decapitaton Island to train.

Abilities


Koma seems very confident in his own power. He was able to sense Behemoths presence when he appeared at the new school. He is also very fast seeing as he was able to quickly get beside Agiel and knock her down when she was attacking Aoi.

He can lend his power to a human he's made a contract with, for example, imbuing Aoi's wooden sword with demonic wind.

He is also able to conceal himself from those he does not want to see him. He is impossible to see by those with no spiritual awareness. When he appeared before some of the delinquents they could not see him and Furuichi could only see a shimmer.

Vs. Beelzebub
While Aoi and Oga were training to learn Ankokubutō, Koma and Beel had their own fight to find out who is the cutest....ultimately, Koma lost the fight.
