The Definitive Technique: The Z Triangle!.Raimon are getting ready to play their next big opponent - Kidokawa Seishuu, which just happens to be Gouenji's old school. Certain members of that team still carry a grudge against him and will stop at nothing to get their revenge. This results into a practice match with the Mukata triplets vs Endou. Unfortunately, Endou doesn't stand a chance against Triangle Z! Will Raimon lose at this rate?
