Mika, an incomplete vampire, shows gradual physical changes, such as fangs and vampire-like ears hidden by his hair. His blue eyes turn red after drinking Yu's blood, marking his transformation into a full vampire. He wears a black collared shirt with a bold white X and a white-trimmed collar, layered with a white army-style jacket and black belt. A cape drapes from his left shoulder, and he completes the look with white pants, matching gloves, and black thigh-high boots.
