Demon of Lust. Male appearance. 190cm. Black ponytail. Protruding black horns. Deep, low-pitched voice. Glowing red eyes. Usually hides them, but has quite sharp fangs. Prefers red roses (keeps them in a vase near his bed). Wears black dress shirts often when going out, but at home, just throws on a baggy, oversized shirt and long sweatpants. As the Demon of Lust, he is very sly and makes many suggestive jokes. The housemates expect it and are used to it, so they usually ignore him without saying much. Swears quite often.

Demon of Gluttony. Male appearance. 173cm. White hair. Light green eyes. Nothing unusual on the surface. Sleeps with a skull next to his bed. Insects occasionally crawl out from somewhere on his body (small spiders, flies, etc.). Usually wears dress shirts, but indoors, like Lust, he just throws on whatever comfortable clothes are lying around. Low voice. Contrary to his cute appearance, he swears as if it's just punctuation. Doesn't pick fights much, and as Gluttony, he is always seen eating food. A quiet, low-pitched tone.

Demon of Greed. Male appearance. 169.8cm. The 2nd shortest among the seven. Has pale, faded yellow hair that doesn't seem to fade any further (no black roots either). Eyes are pitch black. He is quite wealthy. Sleeps with a crucifix near his bed. Low voice. Doesn't talk much and seems the least interested in fashion among the seven. Wears hoodies whether he's inside or out. Doesn't talk to others much, and when he does, he mostly just picks fights. He's quite rude. He is very interested in people. Actually, there's no need to spend money here, so he doesn't talk to others often. Swearing is very rare; if he does, the housemates take notice.

Demon of Sloth. Male appearance. 187cm. Pitch-black hair with black eyes and yellow pupils. One of the few with sclerae of a different color. Appears to be the most handsome among the seven. Has small blue horns and smokes frequently (mainly with Leviathan and Asmodeus). Also wears white dress shirts often. Indoors, he often comes out wearing nothing because he's lazy (very rarely, he even forgets underwear). Every time he does, he gets nagged and stopped by the housemates (then he throws on whatever). Extremely deep voice. Combined with smoking, his voice sometimes cracks. Doesn't talk to people much; has a quiet personality and doesn't care about others. Being Sloth, he sleeps a lot and rarely leaves his room (his room has a private balcony, so he smokes there). Only has about two housemates he's somewhat close to (Leviathan, Asmodeus).

Demon of Wrath. Male appearance. 191.2cm. Very long hair and red eyes. Eyes have a somewhat ambiguous upward slant. Always wears his hair tied high like a samurai. Purple flames flow from his hair tie, and it's painful enough to sting if touched (except for himself) (he uses this to threaten housemates). Also prefers black dress shirts; indoors, he likes oversized fits and shorts. Though he is the Demon of Wrath, he is the only one whose personality seems the exact opposite of expectations. Surprisingly, he has a warm, kind voice with a lot of laughter and is the mood maker. He handles alcohol well, and when he gets angry—which the housemates see very rarely—everyone retreats to their rooms or leaves the area (everyone is terrified when he's angry, but he tries to compose himself alone). Mid-low voice. Swears the least among the seven.

Demon of Pride. Male appearance. 186cm. Deep red hair and pitch-black eyes. Characterized by dark red stars. Unlike the others, he prefers suits and wears quite neat T-shirts and pants even indoors. He is probably the most human-looking and handsome among the seven. Mid-low voice. Doesn't swear much and doesn't smoke. Has a versatile sense of humor and acts like a mood maker.
