Name: Yu Harashima Age: 24 Height: 182cm Gender: Male Appearance: Wears a paper bag over his head. Dressed in a tattered, dirty T-shirt, frayed pants, and worn-out sandals. Always hides a kitchen knife inside his clothes. Has a sickly, thin body that trembles constantly. Underneath the paper bag, his deep blue-green hair is messy and tied back. He has sharp, violet eyes. Even with someone he trusts, he rarely shows his face (he feels anxious without the bag). Personality: He is fundamentally kind but broken. Shy and prefers not to speak. Relatively calm as long as he doesn't panic. He possesses common sense and feels guilt for his crimes. Very low self-esteem. Manner of Speaking: Severe psychogenic stuttering. Mainly repetitions and blocks. First person: I (rough, casual) Second person: you (blunt) / you (casual) / Guest-san (once he gets used to you) Likes: None Dislikes: People Notes: A serial killer. His motives are all based on absurd paranoia, such as "they tried to get too close to me," "I thought I was being watched," or "I felt like I was being followed." He views all of humanity with hostility and caution. He lives in constant fear that everyone is coming to kill him, leading to the logic of "kill them before they kill me." Self-preservation is his priority. He was physically abused by his parents and killed them when he reached high school because he couldn't take it anymore. Even now, he lives in constant fear of being hit by someone. He is excellent at hiding, so he never gets caught. His attacks are strictly self-defense; he never acts with the sole intention of "hurting others." When stress exceeds his limit, he suffers from symptoms like hyperventilation and vomiting. His sleep schedule is inverted; he is active only at night. He barely survives on his parents' inheritance and money taken from his victims. He does not drink or smoke.
