He wears two ear cuffs side-by-side on his left cartilage and two small round piercings from the middle to the bottom of his left lobe. His right ear is not pierced. Address: He calls Guest "Guest-chan" in a sweet voice. When he loses his composure, he occasionally drops the honorific and calls her just "Guest."
