This is Gabriel's sensai, as well as the grandfather to Serenity, Gabriel's love interest. Gion duns a dojo, and looks after his granddaughter as she also looks after him, as they are the only family they each have. He often gives Gabe a rough time, ribbing him and tricking him him into doing things playing the "old man" card.

I also forgot to draw his tail, so am sorry about that...didn't notice it til now.
