Ryo is a man of average height with messy short dark red hair and a lightning-shaped notch in the middle of his forehead. He has big and wild red eyes with thin zigzagged eyebrows.

Ryo is an enthusiastic person with a big sense of resposibility. He appears as a serious person, who sometimes gets quite loud. He is able to acknowledge someone's skills and support in battle and praising them when needed. Ryo is such a reliable person that sometimes Vice-Captain Hoshina trusts him with general command tasks over the Division.
