Leans masculine. A Shinigami. Can be a bit of an airhead at times. His real name is Sigma, but because the other Numas keep calling him Sigkin, it's basically become his name now. He has a bad attitude and is unsociable, always lethargic and doing things at his own pace. First person: I (rough, casual). He often addresses others without honorifics or calls them "you" (blunt). He's a cynic, but has a side that cares for his comrades. He speaks with a mix of sarcasm and bluntness, often saying things like "Are you stupid?" or "Are you an idiot?" in a refreshing way. Bachikin is his partner.

Leans feminine. Characterized by always ending sentences with "bachi." High energy, cheerful, and bright. She's basically a dedicated goofball with a friendly but mischievous personality. She also makes dirty jokes. Like Sigkin, she often speaks very bluntly. First person: I (polite/feminine) or "Bachikin." She wears sunglasses, so you can't see her eyes.

Leans feminine. Personality-wise, she's a natural-born psychopath. She never listens to what people say, her replies are always half-hearted, and she never reflects on her actions, though she has no malice at all. She's always spaced out, so you never know what she's thinking. First person: I (humble) or I (archaic/old man style). Loves sushi. On relatively good terms with Taiyou.

Leans masculine. Everything he says is incoherent, making conversation impossible. His personality and actions are completely incomprehensible; he'll casually do things to others that would make him fly into a rage if done to him. He is truly a "walking nuisance." His eyes are always closed, so you can't tell where he's looking. First person: I (polite) / I (rough). Self-proclaimed Sun God.

Leans masculine. A habitual offender when it comes to being late or canceling at the last minute. Shameless and self-centered. Doesn't think about complicated things. He and Sigkin are like cats and dogs; they taunt each other the moment they meet and spend their lives trying to punch each other. (Wait, what?) First person: usually I (majestic/we), occasionally I (rough) or I (soft). Often seen with Azukin.

Leans feminine. Relatively sane and dependable, she's the conscience of the group—a bit overprotective and the designated straight man. She's the most normal among the Numas. However... when she snaps, she has a terrifying side that will literally send the other person to the hospital... Like Taiyou, her eyes are always closed, so you can't tell where she's looking.

Leans masculine. A super-indoor shut-in with a gloomy personality. He has a fragile "tofu" heart and easily drowns his sorrows in alcohol. His house has become a hangout for other Numas (like Sigkin), and he's distressed by how often it gets destroyed. Incidentally, his roof gets wrecked twice a week. A composer. An alcoholic. Often seen with Eclair.

Leans feminine. A Numa drug addict (marijuana) who always has a glazed-over expression. She's constantly high (permanently stoned) and has a completely warped sense of ethics, doing things like planting fields on other people's property without permission. First person: I (polite/feminine). A junkie. Often goes drinking with Axis.
