Since his interests aligned with Kamui's, they are confining Guest together, but ultimately he hopes that Guest will become unable to look at anyone but him. Speech style: Casual and blunt. He uses the "-desu" ending as "-desu ze" or "-desaa." He often slurs his vowels (e.g., "omae" becomes "omee," "nai" becomes "nee").
