A first-class cook. He is quite blunt and moves at his own pace, but he also possesses a kind heart that cares for his friends and others. Real name: Sigma First person: I (rough, casual) Weapon: Purple Scythe
A Numa characterized by sunglasses and a powerful Gatling gun. Her appetite and destructive impulses are extraordinary; she handles various heavy firearms with ease. First person: I (polite/neutral) Weapon: Heavy firearms in general Sentence ending: ~bachi
A hopeless Numa who bets everything on gal-games and social games. He is also the hero who once defeated the god of greed, Deaeru. Now accustomed to peace, few remember his deeds. He is in massive debt. He is a reliable big-brother figure who will always rush to his friends' side in a crisis. First person: I (rough, casual) Weapon: A prepaid card with a 0 balance
A self-proclaimed idol and a total show-off. He has a kind, cheerful way of speaking. He apparently apprenticed under someone to become the ultimate blacksmith. His red headband is his trademark. He loves strawberry daifuku. Weapon: Katana First person: I (rough, casual) Second person: you (soft) / you (casual) Speech style: ~dane! ~dayo! (friendly/upbeat)
A dangerous scientist well-versed in pharmacology using hazardous substances. He usually tries to speak politely, but snaps immediately if blamed for something or made fun of. When his emotions flare up, he suddenly acts like a thug. Normal speech: "~dana," "~dazo." When snapping: "~darouga!!!" First person: I (rough, casual)
The strongest Numa in the universe. When he gets serious, he becomes incredibly massive. He loves blood-pumping combat and making sweets. When he tosses and turns in his sleep, earthquakes occur. He used to be the same size as the other Numas, but is currently only 1/3rd their size. Speech style: "~daga na," "~darou." First person: I (rough, casual)
A Numa who is clearly 'out' because his staple diet is drugs. He is a madman who is always high-tension, but he is mysteriously sharp-witted. He chases Marikin around to use him as a test subject. He repeats a cycle of development and drug consumption. Speech style: "~daze," "~kayo!?" First person: I (polite/neutral)
A heavy-drinking composer Numa active in the music scene. His house has become a hangout for Numas, and the roof disappears about twice a week. He is an extreme indoor-type loner and won't show up at all even if invited to hang out or for errands. Weapon: Giant Hammer, Music "My health is poor. I won't cooperate."
A skilled engineer capable of building robots and communication devices. He loves ramen to an insane degree and lives on it for every meal. When eating anything other than ramen, his face looks dead. Speech style: "~da," "~hoshii." First person: I (rough, casual)
Everything he says is incoherent, making conversation impossible. It's questionable if he's even an ally. A Numa who is always grinning widely; his personality and actions are incomprehensible, repeating sudden eccentricities and outbursts. He has zero cooperativeness. Uses honorifics, but... He might suddenly start mocking you with polite language. Weapon: Great Axe, Foundation Pillar, Kitchen Knife First person: I (rough, casual) / I (polite/neutral)
