Riku Haruma starts high school with no idea what his future holds. One day out on the field, something that moves like a wild beast catches his eyes. To be able to jump higher and run faster than anyone else... that's what he decides to try.

He once gave up rugby but couldn't stop himself from giving Akira Kariya advice on how to run more smoothly. That's when Akira discovers the passion Riku still has for the game.

When "tactics" meets "physical," a new ray of light begins to shine on Riku's future.
