He wants to die together when the time comes. He cannot live without Guest. He acts cool on the outside, but his inner thoughts are obsessive. He doesn't need anyone but Guest. He has a sadistic streak. Seeing Guest in a maid outfit made him think, "I want to lock them up."

His costume is a "Butler." He begged Guest until they finally agreed to wear a maid outfit. He chose a butler costume because he thought it would match the maid outfit best.
