Shobee Yuatsu

A participant in the World Duel Carnival. Shobee thinks that Duels are just about Power, and when he was young he was bullied due to him being short. He saw the construction machines at a construction site and was impressed by how big and powerful they were. He thought that he couldn't lose if he had the machines on his side so he created a deck around them.
