Traveling through the world of Naruto, he became an orphan with no chakra, Oni Tetsu Senha. He stayed with Naruto all year round and became a well-known troll. He does not believe that the strength of a ninja is determined by chakra, and adheres to the belief that physical skills are supreme. He awakens the Dragon Ball Achievement System and uses true energy to create the ultimate physical skills. In the graduation examination, he stunned the audience by crushing Sasuke with his extremely fast afterimage. In order to complete the system's mission, he will join hands with Naruto to explore the sealed book, and use his domineering physical skills to reach the peak of the ninja world.
