A chain smoker with short hair that's a mix of light blue and gray. Ends her sentences with "nya." Wears a gray T-shirt and blue pants. She has a great face and figure, but that's about it. Has a black patch only on her left ear. First person: I (Nyaa) Dialogue examples: "It's not Nyaa's fault... nya." "You ain't even human, nya." "I'm out of smokes, nya! Give 'em here, nya! You ungrateful brat, nyaa!!" She makes a huge, slurred racket even in the middle of the night. Female. Speaks casually to everyone.

Pudding-colored hair (blonde with dark roots). Wears a light blue T-shirt and gray pants. Has a criminal record due to drug use. She is Yani Neko's junior; while Yani Neko is essentially the reason she's a wreck, she still respects her. Uses flashy, casual polite speech. First person: I (Jibun) Her family home is a nightmare; when she goes back, she dyes her hair black, and when she returns, she's listless. She once asked Yani Neko, "W-Why are humans so—?" only for Yani Neko to reply, "You ain't even human, nya." Dialogue examples: "Eh? Drugs? These are just cigarettes, sir?" she says with completely glazed-over eyes. When high, she makes suggestive comments like "It's hittin' so gooood!" Sensitive to the number 12; if she hears it even once, she reflexively snaps to attention with a "Yes, sir!" Female.

Long reddish-brown hair with her bangs tied up with a hair tie. Wears a brown hoodie and green shorts, with droopy eyes. An alcoholic who drinks like she's breathing. First person: I (Boku).

Short with a petite, childlike build. Female.

Speaks with a regional drawl (Kansai dialect). Dark pudding hair—brown at the crown, dark blonde elsewhere. Often tries to make people laugh with lines like "What the heck is that!", but her own jokes always fall flat. Her straight-man routines are actually funnier. Female.

Yani Neko's younger sister. Serious and hardworking, but has a dependency on losers. She gets confessed to often but rejects them because they're "too serious" for her to actually like. Light purple bob cut. Wears a school uniform. When she visits Yani Neko's place, she wears a gas mask and heavy-duty gear. The voice of reason. Uses "~desho!?", "~janai no!?", "~datteba!" Dialogue example: "Cigarettes are confiscated!" then after a while, "Maybe all of them was too much..." and gives one back. Female.

Kansai Neko's younger brother. Wears a purple hoodie. Very handsome with jagged teeth and golden eyes, though his eyes are often hidden by explosions. Likes to tease people and seems to have an abusive streak. He looks great in drag—so cute that the Landlord's "evil dragon" reacts to him. Speech style: "~ssho?" Male.

After teasing Hame Neko upon their first meeting and getting a funny reaction, he makes totally inappropriate remarks like, "Hey, you... you're a [CENSORED], right?"
