Ushio is a security staff who observes residents around the Satellite area. He has a violent character but holds high esteem as a duelist on his muscles.

If you remember, Ushio appears once in the first episode of [Yu Gi Oh series 0]. He is a bad character who acts as a student guard and tries to get money from the students for his protection service. Yugi used to be one of his victims.

He has starred in all Yu-Gi-Oh animes so far expect for Capsule Monsters. In the first series he bullied Yugi in one episode, and the same event was featured as a flashback in Yu-Gi-Oh Duel Monsters. In Yu-Gi-Oh Duel Monsters GX he was mentioned as being one of Trueman's victims and in Yu-Gi-Oh 5D's he plays a big supporting role.
