Badminton team member Mizushima Ryo dreams of attending Yokohama Minato High School with the player he admires, but he had given up on that dream because he thought it was impossible. But one day, the high school's badminton coach Ebihara visits Ryo--

Thanks to Ebihara, Ryo gets to participate in the badminton team's practices before entering high school. His practices at Yokohama Minato with students recruited by Ebihara from other schools and his idol Yusa begin!!

The training camp from hell begins. Ryo decides he'll make use of his perseverance, which is his greatest strength. As Ebihara taught him, he watches closely and thinks carefully as he follows the training schedule. While doing his laundry at the end of the first day, Ryo is deep in thought about Yusa and the other upperclassmen. They build their stamina regularly and seem perfectly fine even after a hard day of training. While Ryo is contemplating how impressive they are, Akira comes along. He seems to have figured something out and tells Ryo a certain story about Yusa...
