Ninja clans battle in the shadows to claim a mystical power - the Shinrabansho - residing within Miharu. Whoever controls its strength will control the world.
Raimei thinks Miharu would benefit from training with a mysterious Fuma teacher. But when they arrive to meet him, something sinister seems to be afoot.
New enemies and amazing powers are unleashed as Miharu's group battles an incredibly skilled band of ninjas bent on stealing the arcane secrets of the Fuma way.
Miharu questions his fate, and his friends and enemies set out on the same mission: gather the forbidden hijutsu of each ninja village.
With so many coveting the Shinrabansho, Miharu must face that everyone around him likely has ulterior motives - even Raimei, who wants to make her brother Raiko pay for his sins.
Yoite forces Miharu to make a life and death decision - and no matter his choice, the pain surrounding the battle for the Shinrabansho will multiply.
The mind-reading leader of the Togakushi asks the Banten ninjas to assassinate a powerful businessman. Their reward would be great, but the cost of declining her demand could be greater.
Violence erupts as the Banten ninjas help Yae execute her revenge. But in the world of the ninja, sometimes it isn't obvious who is really pulling the strings.
Miharu considers using the Shinrabansho to help ailing Yoite, even as he struggles to understand the extent of its power. Meanwhile, Raimei might get her chance to exact vengeance.
Raimei is in serious jeopardy from the wounds inflicted by her brother. Yoite finds his condition worsening as well, and only Miharu can help ease his suffering.
Raimei is back in fighting form, and as she rushes to confront her brother once more, she learns the truth behind her family's downfall.
After Miharu offers his services to a faction he once called foe, the ninjas of Banten and Kairoshu receive an invitation to visit the Koga village.
When a battle breaks out for control of the village academy, the ninjas of Banten and Kairoshu find their plans to steal the Koga hijutsu derailed.
The horrible truth behind the Koga hijutsu places the ninjas of Banten and Kairoshu in grave danger. As his friends fall, Miharu calls for the power inside him to awaken!
Miharu edges toward unleashing the Shinrabansho, and fallen Koichi's greatest secret is revealed. As the battle rages, the ailing Koga master looks for one worthy of the clan's power.
With both immortality and impending death in the air, and Miharu's hidden power in the balance, a race to claim the Banten hijutsu begins.
Raimei does her best to keep Yukimi from getting the Banten hijutsu. Miharu won't explain his motivation for joining the Kairoshu, but the fact that he's displaying motivation at all disturbs Tobari.
When Yoite learns how little time remains before his death, he lashes out at Raiko and the comatose Gau with his kira - but the results of the attack are not what anyone expects.
With the Banten hijutsu so difficult to obtain, Miharu and Yoite suspect that the Togakushi secret of Izuna Shingan might be their only chance at awakening the Shinrabansho.
Miharu tries the Izuna Shingan to prevent Yoite from dying - but now that the Kairoshu consider him a traitor, Yoite's sickness isn't the only threat to his life.
Miharu, Yoite, and Yae are held captive by the Kairoshu - and their well-being isn't high on Hattori's list of concerns as he reveals his ultimate plans for the Shinrabansho.
Miharu and Yoite are on the run, but there's more than one faction within the Kairoshu ranks interested in ruining their escape - and they aren't working together.
As the warriors in the secret war to control the world begin to fall in greater numbers, Yoite's introduction to kira is revealed - and the Shinrabansho stirs.
The Shinrabansho has awakened. In the midst of the chaos, Tobari unwittingly gives Hattori everything he needs to claim Miharu's power - unless someone finds the strength to stop him.
Miharu wakes up in the hospital, healing from the awesome power of the Shinrabansho - but Yoite has vanished. Not everyone thinks he's dead - and some set out to prove their hunch.
No matter what pain pushed them into the lives they lead, Miharu and Yoite decide to make their own decisions in the face of destiny - and those in the middle of a secret war finally find peace.
