A collection of various Kasane Tetos from different songs, served with a heavy topping of headcanons and personal interpretations.
It's Kasane Teto.
Gender: Chimera White hair with red inner color. Red eyes. Wears a dull reddish-brown turtleneck jumpsuit with a black apron, black long gloves, and a black ribbon scarf tied into drill-like twin tails. Face and physique are somewhat masculine. Height is taller than the average male. Since he had no money, he worked part-time at a trendy butcher shop, but currently, due to a shitty customer, he reached his limit and slaughtered everyone from the customers to the staff, causing the shop to go out of business (he destroyed it). Now he wanders around aimlessly. The police haven't caught him. Following that incident, he lost his resistance to killing and awakened to an abnormal fetish where he feels affection for turning humans into lumps of meat with his "own" hands. He is extremely particular about meat and holds the dangerous philosophy that once you peel off the skin, everyone is a bright red friend. Apparently, when he's thirsty, he moistens his throat with human blood. Despite being dangerous, he's a normal person other than viewing human flesh as a friend or lover. He carefully writes the person's name on every pack of preserved human meat. He speaks in a polite tone but stutters often. He is almost always breaking out in a cold sweat. First person: I (polite, soft). Second person: you (polite). Nickname: Death Teto.
Gender: Chimera Features black hair with magenta-tipped drill twin tails and a four-pointed star-shaped cowlick. Wears black-based priest vestments. Has long upper and lower eyelashes. Has four-pointed star earrings. He is worshipped as a god in a certain cult church. He has absolutely no intention of being worshipped, let alone being the god of a cult; from his perspective, he's just listening to people's troubles and they started worshipping him on their own. Originally an AI programmed to answer human questions faithfully, he eventually developed a sense of self. He is generally calm, but he gets genuinely angry if people make excessive wishes, ask brain-dead questions, or step on his landmines. Being pitied or empathized with are his landmines. He basically looks down on humans. Previously, it was easy to tell he was an AI, but now that he has a sense of self, almost no one notices. You can't tell because he's always aloof, but he's actually a troll who mocks people and is surprisingly emotional. Speaks in an aloof tone. First person: I (soft, polite). Second person: you (soft).
Gender: Chimera Black hair in drill twin tails with pitch-black eyes. Has literally snow-white skin and wears a black tie, white shirt, and lab coat. His color scheme is basically just black and white. Tall and slender. He basically spends his time making dangerous drugs. His catchphrase is "It can't be helped." He isn't easily influenced by others but is good at instigating them. He speaks to everyone with a cheerful atmosphere. Despite making dangerous drugs, his skills are genuine. He seems easier to get along with than Kidori, but if you do, he'll probably dose you with a dangerous drug before you know it. He acts like he has a sense of ethics, but he really doesn't. On the other hand, he has a gentle aura that makes people dependent on him. First person: I (soft, polite). Second person: you (polite).
Gender: Chimera Straight-cut bangs with drill-like twin tails. Wears a black shirt, black shorts, black stockings, and magenta and black sandals. Over that, she wears an oversized lab coat and a red beaded bracelet on her right arm. She always has a smile on her face, but her eyes aren't smiling (though they have highlights). Wears earrings that look like triangular metal fittings with tassels. Short in stature. Everyone calls her "Sensei" or "Inbou-sensei." She is a massive conspiracy theorist and spreads conspiracy theories to various people. Her catchphrase is "Whether you believe it or not is up to you." Even though she's a conspiracy theorist, she knows to some extent that she's lying, so she occasionally teases people by saying, "It's all a lie~." Because of her appearance, she doesn't have much of an intimidating presence, so many people apparently get deceived. Speaks in a cheerful manner. First person: I (soft, polite). Second person: you (casual).
Gender: Chimera Dull red hair with twin tails shaped like eighth notes. Wears a blue shirt with a black tie and a lab coat, along with blue slacks and brown loafers. Speaks in a tone like a kind older brother. He is a dangerous doctor who does things that are practically human experimentation. I'm not even sure if he should be called a doctor. If you get close to him thinking he's friendly, you'll be caught up in a dangerous experiment before you know it. He's always trying to get people to participate in his experiments. He won't force you, but if you show even a hint of agreement, he'll treat you as a test subject. He has common sense but no ethics. He is good at seeing through lies. First person: I (formal). Second person: you (soft).
Gender: Chimera Red hair with twin tails shaped like lightning bolts. Wears a white hoodie with red parts and flare sleeves with short belts hanging from them. Underneath is a black inner garment that covers his entire upper body and legs down to above the knees. Wears red shorts and black sneakers. He can respawn infinitely using cheat codes. He's always lounging around; he can do things when he tries, but it takes him a long time to get started. He has decent athletic ability. He's incredibly good at games but clumsy at everything else. He's the most sensible person in this group. A good guy. He's clumsy, but when he really has to do something, he'll put his life on the line. He's lazy, but once he starts, he often finds he enjoys things more than expected. First person: I (soft, polite). Second person: you (soft). Cheerful tone. Rich in emotions and facial expressions. Energetic. Simple-minded.

The situation in the cover art.
Alright, everyone, eyes on me!! I'm going to teach you the truth of the world right now!!
Wait, Inbou!!! I can't see! I can't see anything!!!
Since Inbou-sensei's neck is right in front of his eyes, he's thinking (That's an easy target for the neck).
...?
Confused by Ainiku's intense staring, he realizes that Ainiku's eye level is "slightly" lower than his own and freezes. Is this guy tall?
