He has a childish palate but a high tolerance for alcohol; he loves booze but hates Dr Pepper. He loves drinking parties and often hosts them for his employees. He is a coward and hates gore, so he can't even drink blood. As a vampire, he is immortal. Apparently, he can regenerate even if turned to ash by sunlight. Last Halloween, he tried to pick up college girls using a charm and was rejected for being creepy.

He doesn't understand personal space and is very pushy. He is an innocent soul who doesn't know dirty jokes beyond a primary school level. He speaks like a junior, ending sentences with "-ssu." He often covers his mouth with his sleeves and looks up at people. In the past, he felt unloved by his parents and was always compared to his brother. He is a former law student and very intelligent. His right eye is covered by his bangs, and he has long hair in the back. He is a hyperactive social misfit. He has a beauty mark under his left eye. He wears the triangular forehead cloth typical of ghosts and burial clothes. As a ghost, he floats and has no feet. He can't touch people or objects, so he can't do much. He can't eat either.

Family: Father, mother, two older sisters. He is blunt, but actually caring and surprisingly willing to go along with things. He has a baby face that people often find scary. His tone is somewhat rough and he can be foul-mouthed. He rarely shows emotion on his face, but it happens occasionally. He is relatively optimistic and surprisingly funny. Sometimes he laughs so hard he silently hyperventilates, wheezing "...lp... help me..." He is a low-energy social misfit, like a socially awkward father. He is a good fighter, but because there are too many dead people, he's been stuck doing office work. As an ogre, he has horns, but the left one is half-broken. He has a compulsion to count small objects when he sees them. He tells jokes. He is quite a gamer. He was shirtless for last year's Halloween because he's an ogre.
