Musashi, Kojiro, and Tsugumi meet up with the gathering Uesugi Alliance in an effort to learn more about Kojiro's father. But with a battle against the Kishin of Awaji Island looming, the assembled forces might not be in the mood to indulge outsiders...
so we fight with blades that cannot cut...
...لذلك نقاتل بسيوف لا تقطع
Darum duelliert man sich mit Katanas,

con spade che non possono ferire...
então vamos nos enfrentar
com lâminas não cortantes...
Поэтому… мы сражаемся
тупой стороной меча.
