In the lawless "Stray Dog Capital" of Yasaka during Japan's Warring States period, the wandering samurai Hiro recruits six warriors to confront the mysterious Kagura. Among them is Takahiro, a young but experienced archer. He joins dual-sword wielder Atsushi, lone wolf Makidai, ninjas Matsu and Usa, and bandit leader Akira, forming a group of seven combating antagonistic forces encroaching from across the sea. Takahiro's archery skills provide crucial tactical support within the team during their battles against these sinister threats.
