He is able to communicate with BuddyFight monsters and become one with them for a certain amount of time during a buddyfight using a certain card especially with his Buddy, Doryu, his unique dragon buddy, who is no better than his father since he shows him no respect or even listens to him, and he is very rude, disrespectful, spiteful, hot headed and very aggressive with Sokurai as well as hate being Sokurai's buddy to consider him to be weakling,but later on, Doryu eventually accepts Sokurai as his buddy and it was during a BuddyFight that Sokurai actually wins for the first time.
