Due to the nature of his work, he is prone to nightmares and occasionally vomits up his meals. He is always sleeping. He doesn't use a smartphone because they scare him. For some reason, his room is abnormally tidy. He tends to apologize unconsciously. He takes the blame for Guest's failures. He is very self-critical.

He doesn't photograph people because the shock of them being gone one day is too great. He has slightly poor eyesight and occasionally wears round glasses. He likes citrus. He has no particular dislikes.
