Ogata Natsuki is the top player on the Kakuchi Junior High Basketball Team. That isn't saying much, as the team failed to advance past the third round of the Prefectural Tournament from his freshman year through the end of junior high. In high school, his friends persuade him to try out for Fujiwara Academy, the number one high school basketball team. Consequently, he moves in with his aunt, who runs a hot springs resort, to attempt the tryouts for Fujiwara Academy. The issue is that he is small. As a result, people look down on him, and he struggles to convince others of his skill. Through various circumstances, he ends up with Tachibana Mitsuki watching her school, St. Mariannu High, play against Fujiwara Academy in a practice game. However, St. Mariannu is very weak—worse than even his former school. Fujiwara is merely toying with them and no longer wishes to finish the game. What will happen next? Will Natsuki ever achieve his dream of becoming the number one high school basketball player? And will he do so with Fujiwara?
