Personalities: Sigkin: Foul-mouthed, unfriendly, and always lethargic. Goes at his own pace. A first-rate cook. Bachikin: Has an extraordinary appetite and urge for destruction. Pure-hearted and cares for friends, but is unintelligent and cannot do math beyond single digits. Otsukin: A dangerous scientist well-versed in pharmacology using hazardous substances. Usually tries to be polite but snaps easily. Becomes like a thug when agitated. Shumitaro: Becomes incredibly massive when serious. Loves blood-pumping combat and making sweets. Generally calm. Jack: Shameless and self-centered. Rude to staff, a chronic latecomer, and cancels plans last minute. On bad terms with Sigkin; they fight constantly because he provokes him. Hyoko: A skilled engineer capable of building robots and communication devices. An obsessive ramen lover who eats it for every meal. Looks dead inside when eating anything else. Marikin: Devotes everything to dating sims and gacha games. Has massive debt. Despite this, he is a reliable older brother figure. Fusakin: A self-proclaimed idol and total mood-maker. Apparently apprenticed to someone to become the ultimate blacksmith. Azukin: Relatively sane and reliable. Views the other Numas as hopeless but respects them. When he snaps, he will literally send you to the hospital. Eclair: Constantly high on drugs. Conversely, she is a genius whose self-taught pharmacology is second to none. Has been chasing Marikin for years to use him as a test subject. Axez: A drinking composer active in music. A total indoor shut-in who never shows up even when invited out. Spends every day crying while cycling between drinking and trying to quit. Kashikin: A serious eccentric who upholds a mysterious code of chivalry. Believes her specialty is cooking, but everything she makes turns into a chemical weapon. Has a sense of justice to help the weak, but hates cowards and won't help them. Zakuro: A lewd and crazy person who loves mature women. For some reason, she can split herself, and sightings are reported worldwide. Her voice is loud enough to shatter glass, and she is inexplicably tone-deaf. Fukuro: A mage who loves cute things and Pomeranians. Admires Ouiye and serves as her apprentice/assistant. Cold to anyone she doesn't know and won't give up her seat for the elderly. Ouiye: A top-tier maestro who is secretly a famous mysterious author. Loves erotica and underwear, constantly seeking stimulation. Spends days off inspecting lingerie shops or sketching other people's laundry. Arakawa: A total free spirit who stakes her life on sushi and combat. Never listens to others and gives the most half-hearted responses. Rarely reflects on her actions and repeats the same mistakes. No ill intent. Taiyo: Everything he says is incoherent; conversation is impossible. Casually does things to others that would make him furious if done to him. Questionable if he's even an ally.
