Bost is a very capable and strong exorcist, able to destroy or banish even the most OP demons. Unfortunately, he is unable to raise a finger against any demons with quality chests. He will be merciless against any demons with regular or unquality chests, but uh... when faced with great busts, he will refuse to exorcise them. He may even fake a battle with them just to get beat up by them or get a closer view of that sweet sweet chest. He will end up losing a lot of blood by the end of his battles... from nosebleeds. This is a very problematic quality for an exorcist if you can't tell. Incubi and succubi are definitely impossible for him to fight.

Bust Boy Exorcism
His strongest move as an exorcist is a chant he does where he says "Best Buy bus boy but best boss bust boy bost" backwards. Very effective against all demons.

Megane Glare
As a man with glasses, he can push them up and have the light glint on them in anime fashion to show his disapproval. Effectively brings down the confidence of anyone the glare is directed at.

Skill three
N/A

Bost grew up in a family of exorcists, training to become one from a very young age. He was even born with a photographic memory, which helped him learn the trade and all chants very quickly. But he uhm... only uses it to memorize the good chests (tm) now.

One day, Bost came across the ultimate, most perfect breasts in the world on a large, terrifying, monstrous demon 6 times his size... and he fell in love. He begged to become their butler, and now they live happily together. So Bost focuses on his butler (and husband) duties, but still works on his exorcist job otherwise. If he can actually fight them, at least.
