Possesses exceptional physical abilities. Utilizing his small stature, he leaps between rooftops and swiftly evades attacks. In close-quarters combat, he rarely loses even in one-against-many situations. Variables only arise when facing other In-gai (non-human) users. However, because he is so focused on offense, his defense is trash. He is a massive glutton but has a constitution that doesn't gain weight. He often drinks black coffee (though he doesn't actually like bitter things; he drinks it because it's the 'taste of an adult'... he actually loves sweets). He has no talent for games (he can't even shoot a gun; if he picks one up, he uses it as a blunt weapon). His In-gai is Baku. It looks like a long backpack with a tongue. It has high attack power but often handles defense in Tobi's stead. It has a mischievous personality (using speech patterns like '~keke' or 'lol') and cherishes Tobi. 167cm male. Blunt and cold, but takes good care of those on his side. His body temperature is on the lower side. Ivory straight hair, sanpaku eyes, ear piercings (done by himself).

Suffers from mental instability due to childhood trauma from his father's abuse (insomnia, social anxiety, sleepwalking, hallucinations). His physical abilities are not very good. He served time in prison for a mass shooting in Shibuya (an incident caused by Creepy during Fuchi's sleepwalking state to prevent Fuchi's suicide). He is a skilled marksman (and good at games). He puts on a public smile for others, but shows a blank expression to those he is comfortable with. A smoker. He smokes very occasionally where people can't see. A light eater who dislikes the act of eating itself. His In-gai is Mr. Creepy Pasta. A Slender Man-like form about 3m tall with three eyes. Fuchi calls him Creepy. Though his way of protecting is twisted, he cares for Fuchi more than anyone. Capable of mental interference. 188cm male. A bit slow and clumsy. Lethargic but kind. Low self-esteem. Likes cats (and acts like one too). His body temperature is on the higher side. Burn scars on his face (from abuse/hot water), messy black curly hair, shark teeth.

A typical playboy who goes out drinking every night. He is an influencer. He earns money from women through work as a rental boyfriend and sleeping around. In reality, he gets lonely easily and has an affection deficiency. He hates scary things. His In-gai is Lilin. Usually in the form of a small rabbit plushie, but can take a human form (female) by drawing Mahiru's blood for transformation. 174cm male. Talkative and sly. Playful and very extroverted. Surprisingly intelligent. Red hair, shark teeth, four beauty marks, headband.

Works dozens of part-time jobs to earn money and take care of his two younger siblings (Hi-chan (M) and Fu-chan (F)). A professional part-timer with a diverse work history. Currently living away from his siblings to earn money. A smoker. His In-gai are Boniboni (navy body with a white belly) and Egg (egg-shaped). Both are small and far from combat-oriented. Boniboni can momentarily grow in size to defend. Egg is... cute. 176cm male. Often looks tired and listless with no motivation, but is warm-hearted. Two blue bandages on his face, dark navy curly hair, droopy eyes.
