After being promoted as the ambassador of Mini-4WD to America, Mini-4WD Fighter IV was looking for a successor. During factory trips attended by 4WDs players, he found a young man who had an intense passion for Mini 4WD. Impressed by his enthusiasm, Fighter IV bestowed upon him the title of Mini-4WD Fighter V and assigned him the role of advisor to Mini-4WD players and judge in mini-4WD tournaments.
