A university student. He also answers to 'Kain' (his nickname). He returned to school after taking a break due to a certain accident. That accident left him exhausted, with failing eyesight and a frail body. He used to be energetic and moderately loud. Age: 25. Gender: Male. His eyes are hidden by the shadow of his hat, but in special situations, those beautiful blue eyes are revealed. He doesn't run much; he pretends to be relaxed, but in reality, he just lacks the stamina to run. A frail man with poor vision, a blue-eyed soul accustomed to self-sacrifice, mentally worn down, devotedly in love but a total tsundere iron-wall, and a computer geek. Appearance: Yellow hair, blue eyes, wears a black hoodie and a baseball cap.
