Musashi chcąc dotrzymać słowa danemu Kojiro, pilnie trenował... w Szkole Górniczej. Czy takie nauki pozwolą im założyć Drużynę Bushi = Zabójców Oni?

Musashi and Kojiro try to tackle the powerful Kishin that has appeared, but will the two of them really be able to stand up to the class of oni that has dominated Hinomoto for over a hundred years?

With the arrival of the Takeda Bushi band, Musashi is desperate to defeat the Kishin before they can.

Musashi and Kojiro's journey runs immediately into trouble when a mysterious girl steals their vehicle.

Musashi and Kojiro are forced to find a way to escape the Kosameda Castle prison, while Tsumugi is trapped between her desire to protect her friends and the commands of her domineering father.

Tsumugi struggles with deciding what to do next, and Musashi encounters a mysterious, and unhinged, Bushi in black.

Musashi and Kojiro are out to obtain the Kitetsu Blades they'll need to fight oni, but a mysterious ritual involving the mystical swords might prove to be an unexpected hurdle.

Shiro offers to help Musashi overcome his difficulties with Kitetsu Blades and get stronger, but can he be trusted?

As Shiro preys on the other Bushi who have gathered to hunt a Kishin, Musashi has to find a way to escape the lava pit and help his friends.

Musashi, Kojiro, and Tsugumi face off against Nanao and Shiro, and their only hope for victory might be the mysterious entity inside of Musashi.

The Obsidian Goddess tells Musashi that she will be going back to sleep inside of him and no matter what foes he faces, he must not die. Because he is her vessel and because Jisai died before they were able to finish what they started. Musashi wonders what that has to do with Jisai, but the Goddess doesn't have time to explain and decides to show Musashi how she fights in the material world.

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...

After volunteering to take part in a duel for the leadership of his unit, Musashi is confronted with a grim reality.

Musashi's troubles in the Shimazu Unit seem to get worse and worse, with accusations of desertion and espionage thrown his way. At least he can turn to the gentle Michiru to take his side... or can he?

With the connection between Musashi and Michiru, the location of the Goddess Obsidian ends up being discovered by Yataro, who immediately warns the Black Dogs, and the group assembles a strategy to recover her.

Two of the Obsidian Eight are assaulting the Uesugi castle with Yamata no Orochi, while a third member kidnaps Musashi and tries to convince Michiru to kill him.

Battle lines are drawn, with the Obsidian Brotherhood out to defend Yamata no Orochi and capture the Obsidian Goddess, while Musashi works with the Uesugi Band to slay the Kishin and rescue his friends.

Naoe Kanetatsu of the Uesugi Bushi is facing off against Inukawa Seiroku of the Obsidian Eight. But how can he hope to defeat someone whose power seems to be inflicting physical trauma at will?

Shiro's unique powers are enough to overwhelm an entire group of Bushi by himself. Does Naotora really stand a chance?

It's up to Musashi's squad to defeat Yataro, but the Shimazu siblings heading up their assault don't seem to be on the same page anymore.

The struggle to keep the white serpent from empowering Yamata no Orochi becomes desperate, as the truth behind the friction among the Shimazu brothers is revealed.

When everything seemed to have ended with the death of Orochi, the bushi discovered that in reality the fight had only begun.

Musashi tried to save Michiru desperately while the young man's feelings seemed to resigned to his death, something that the young bushi was not willing to accept.
