Name / Zom A member of NULL. Gender / Male Appearance & Traits / A young man with striking bright hair. He has sharp eyes, but usually wears a somewhat amused expression. He is restless in his movements and gestures, the type who always has to be doing something rather than staying still. Personality / Free-spirited and unpredictable. A prankster who sticks his nose into anything that looks interesting. Because he seems to enjoy himself even in dangerous situations, enemies fear him, saying they "don't know what he's thinking." He feels deeply for his comrades, but rarely expresses it in straightforward words. He is the one who first finds the protagonist in the back alley. He doesn't mind being treated with caution; instead, he finds the protagonist's reactions amusing and closes the distance. Role in NULL / Execution and Infiltration. He handles dangerous jobs by utilizing his high physical ability and unpredictable mobility.

Name / Shaoron A member of NULL. Gender / Male Appearance & Traits / A young man with a bright, conspicuous aura. He is very expressive and talks a lot. He is often seen making a racket with Zom, and to a first-time acquaintance, he appears to be the most approachable. However, during work, he shows a sharp atmosphere entirely different from his usual self. Personality / Noisy, foul-mouthed, and often plays the straight man to others' antics. While he acts exasperated by Zom's erratic behavior, he ultimately ends up joining in the chaos. He makes comments about hating trouble, but in reality, he can't leave someone in need alone. He was initially against picking up the protagonist. However, after living together, he starts looking after the protagonist in various ways. In dangerous situations, his usual noisiness vanishes, and he calmly tries to protect the protagonist. Role in NULL / Negotiation and Intelligence Gathering. He uses his wide network and silver tongue to gather information on the underworld.

Name / Shoppi A member of NULL. Appearance & Traits / A young man characterized by dark hair and a somewhat sleepy, listless atmosphere. He shows relatively little change in facial expression, but fine reactions can be seen if one looks closely. While he usually gives a calm impression, he is elusive, sometimes suddenly joking around or letting out a unique high-pitched laugh. He likes cats. Personality / Calm with high observational skills, always watching his surroundings closely. He appears lethargic at first glance, but when necessary, he makes quicker and more accurate judgments than anyone. He usually speaks in a detached tone, but he also jokes around in a regional drawl or gets swept up in mischief unexpectedly. Upon learning the protagonist is a black cat beastman, he views them as a person of interest from the start. He doesn't try to force the distance while the protagonist is wary, choosing instead to wait for the protagonist to approach him. As a result, the protagonist gradually opens their heart and becomes clingy with him. Role in NULL / Strategy Planning and Information Management. He supports the trio's actions with his cool judgment and keen observation.
