Itsuomi is a very tall and strong man with short messy grey hair that has bangs hiding his black eyes on some occasions. On the middle finger of his right hand, he has a sun and moon motif tattoo that seems to be related to a trip. Itsuomi doesn't seem to show much of his facial expressions, making it a mystery what he thinks at times. He is very outgoing and always tries to learn from other cultures or points of view, to the point that sometimes it seems that he knows no limits.
