Kawamura mainly relies on the , a very powerful maneuver that uses 120% of an arm's strength, but puts a lot of strain on his arm. He copies it from Fudomine's Tetsu Ishida, who learned it from his brother, Gin. Kawamura lowers the risk of the shot by using a , which decreases the power. He can use either while jumping to make the , which is hard to return. He later develops the , which is a regular Hadoukyuu performed during an extremely fast dash. It strengthens the shot by focusing all the momentum on the wrist, but it can break the wrist if overused. During his match against Gin, he develops a "Final Hadoukyuu" that, because he accidentally hit with racket frame instead of the gut, the ball vibrates, and thus has power far exceeding Gin's strongest Hadoukyuu, breaking the latter's wrist.
