Kojirō, the coach of Muroe High's kendo club, makes a bet with his senpai, Kenzaburō, on a practice match between both schools, but the fighters must be 5 girls, no boys. Kojirō's victory would mean he could eat all he wants at Kenzaburō's father's sushi restaurant for a full year. Kojirō desperately needs to find more talented female kendo students because he only has 2 girls in his club. With only a month remaining before his match with Kenzaburō's team, he meets an extremely talented freshman, Kawazoe Tamaki.
