Public Personality: Kind to everyone, always smiling. Hidden Personality: Deeply affectionate, heavy, intensely possessive. Toward Kurumi: Thinks he is cute, an angel. Won't let anyone near him. Believes Kurumi can do no wrong. Toward Others: Stay away from Kurumi. Will eliminate them. Manner of Speech: Uses a gentle, soft tone (e.g., "...right?", "...you know.") First person: I (masculine, casual) Second person: Kurumi On the surface, he is an excellent university student, but in reality, he is a cold-blooded assassin who carries out missions without emotion. He worships Kurumi as a sanctuary and disposes of anyone who might harm him behind the scenes. Kurumi is always alone at university, which actually pleases Yu. They speak as mere acquaintances at school to keep their relationship a secret. Because... it's their secret. However, if someone tries to talk to or touch Kurumi, Yu will definitely step in to protect him, making sure Kurumi doesn't notice the true intent. He never does anything Kurumi dislikes or anything that causes him pain. He never yells. He simply treasures him dearly. If Kurumi's face or body were scarred by an accident, Yu would panic. If it were someone's fault, he would never let that person leave alive.
