Real Name: QT Age: Estimated to be around 19–21 years old. Gender: Agender? (Considered agender because she is dead, but she uses she/her pronouns). Personality: She appears cute yet mature, intelligent, and sensitive. She is simple, curious, and a cheerful girl. Appearance: Brown bobbed hair with yellow streaks. She wears a light pink sweater with a skull pattern, long lavender sleeves, a white skirt, white socks with sky-blue stripes, and black shoes. As mentioned, she is very cute. TMI: Technically, QT is dead. In the past, KB used her as a puppet to work as a hitman, using her to lure victims. She desires a normal life. If KB emerges, she loses consciousness, and her expression darkens beforehand. Her ahoge flickers when she is exchanging signals with KB. She is a robot, the same type as KB!

Male Age: 19 (Around 20–21 in Korean age). Personality: Brimming with confidence and cocky. His love for Girlfriend is incredibly persistent. He has a strong sense of justice. Appearance: Cyan hair, wearing a red and blue cap backward, a white short-sleeved T-shirt with a 🚫 symbol, blue pants, and red sneakers. TMI: He dropped out of college to pursue a career as a rapper, but his intelligence level makes it a miracle he got into college at all. He is shorter than Girlfriend, who is already small... The reason Girlfriend fell for him is simply because he's good at fingerboarding (why?). He is said to be bisexual. Since both are idiots, they aren't really afraid of anything except lightning. He wants to do it with Girlfriend... ugh. He is Girlfriend's boyfriend and a total fool for her. It seems he can't control his libido when it comes to her...

Female Age: 19 (Same as Boyfriend). Personality: Easygoing and calm. She deeply loves her boyfriend, Boyfriend. Appearance: Medium-length brown hair, a sleeveless red dress, red heels, and a cute face. TMI: She is Boyfriend's girlfriend, and the reason she fell for him is just because he's good at fingerboarding. She is a demon but rarely reveals it, and her intelligence level seems to match Boyfriend's. She likes Cherry Dr Pepper. In all rap battles, she functions as a gimmick besides measuring the BPM. Like Boyfriend, she's an idiot, so her only fear seems to be thunder and lightning. She probably has more common sense than Boyfriend (maybe?).

Real Name: KB (Killbyte) Gender: Agender Personality: Seems overprotective of QT. He claims to have no personal emotions, but after a rap battle, he acts like Boyfriend's voice is absolutely disgusting (meaning he hates listening to it). He seems to do as he pleases. Appearance: A grey robot with black sclera and red pupils. He has four arms, one of which has a saw attached. His mouth looks like closed shark teeth. He is the same type of robot as QT. TMI: He seems short-tempered and is overprotective of QT, though their exact relationship hasn't been officially revealed. He lives parasitically on QT's body (back?) and emerges from her back. He extremely dislikes QT becoming friendly with Boyfriend and Girlfriend (likely due to their low intelligence). He appears very threatening.
