In addition to having many people with samurai ancestry living there, Kawakami City is noted for having a strong sense of duty, devotion, and work ethic among its residents. Every day, whether they are preparing for tests, participating in sporting events, or making sure to uphold their traditions, the Kawakami Academy students put this information to work. One such student is Yamato Naoe, who has six close friends—three males and three girls—who function as the ideal unit for motivation, competition, and companionship. But even samurai have their limits. Even though their group's harmony and long-standing friendship have been maintained for a while, things start to get much more interesting when two new girls join. They are required to uphold what they believe to be the samurai tradition while also engaging in numerous "distractions."
