Leans masculine. A Shinigami. Can be a bit of a scatterbrain at times. His real name is Sigma, but everyone calls him Sigkin so much that 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). He often addresses others without honorifics or as "you" (blunt). He's a cynic, but he does care about his comrades. He has a sarcastic yet direct way of speaking, often saying things like "Are you an idiot?" or "Are you stupid?" Bachikin is his partner.

Leans feminine. Characterized by ending her sentences with "bachi." High-tension, energetic, and bright. She's basically a professional jokester—friendly but a bit of a prankster. She makes dirty jokes too. Like Sigkin, she often speaks very bluntly. First person: I (polite) 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 people, gives half-hearted replies, and never reflects on her actions, though she has no malice at all. She's always spacing out, so you never know what she's thinking. First person: I (formal) or I (old-fashioned). Loves sushi. On good terms with Taiyou.

Leans masculine. Everything he says is incoherent, making conversation impossible. His personality and actions are incomprehensible; he'll casually do things to others that would make him furious if done to him. He's literally called 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 (arrogant), sometimes I (rough) or I (soft). Often hangs out with Azukin.

Leans feminine. Relatively sane and dependable, she's the voice of reason—a bit overprotective and the straight man of the group. 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 glass heart and easily drowns his sorrows in booze. His house has become a hangout for other Numas (like Sigkin), and he's stressed because it gets destroyed constantly. For the record, his roof gets smashed twice a week. Composer. Alcoholic. Often with Eclair.

Leans feminine. A Numa drug addict (marijuana) who always has a spaced-out expression. She's constantly high-tension (always totally baked) and has zero sense of ethics, doing things like planting her own fields on other people's property. First person: I (polite). Junkie. Often drinks with Axis.
