Nabari no Ou

Miharu Rokujou is asked by his classmate, Kouichi, to join the school nindou club. After refusing, Miharu is asked by his English teacher, Kumohira, to join the club. Although the two look like a student and teacher, theres more to Kouichi and Kumohira then meets the eye.

Miharu and the others arrive when the Fuuma village is under attack. Although the group takes out a couple of the enemy ninja, they are easily defeated by the strongest of the group. Will Miharu have to use his hijutsu to save himself and everyone else?

Finally back in Banten, Miharu, Kouichi and Raimei destroy Bantens ninja skill books. Later, trouble arises when Miharus teacher and former Kairoushuu member Masami Yamase appears. Kouichi and Raimei come to his rescue, but when Raimei finds out that he knows of a person shes after, can she kill him?

Yae Oda, the leader of Togakushi, arrives in Banten, with Katou Sourou. They have a unique offer for Miharu and his group. In exchange for assassinating the CEO of a company that does more then it says, Yae will give them Togakushis kinjutsusho. Its pretty much useless to her as she already knows how to use it, and even demonstrates this on everyone. But when she uses her kinjutsu on Miharu, the Shinrabanshou proves more then a match for Yaes kinjutsu.

A murder brings Raimei closer to finding Raikō. Aizawa is dispatched to stop Raimei from doing anything drastic. Miharu stays with Kumohira while his aunt is away. Meanwhile, the Kairōshū gathers. Yoite begins to show signs of his life force leaking due to Kira. He quickly leaves to find Miharu. Miharu asks Kumohira about the secrets he is unwilling to tell and reveals he will use the Shinrabanshō to help Yoite. An unknown woman finds Yoite unconscious near Kumohiras house. Raimei arrives at a garden where Raikō attacks her.

Raimei, released from the hospital, wants to retrieve the Black Gamon. She and the group encounter Gau, a member of Kairōshū. At Raimeis home, he tells her the truth about the day Raikō killed the Shimizu. Raimei returns to the site of their fight and, after seeing Raikō there, demands her sword back. During the ensuing battle, Raikō, about to finish Raimei off, accidentally slashes Gau, who jumped between them. Later, the siblings are seen in the hospital where Gau is being treated. Raikō returns White Gamon to where it belongs.

Representatives of Kairōshū and Banten reach Alya academy located in the Kouga village to discuss the future of the world of Nabari and are welcomed by the students of the academy since the leader of the village is on his deathbed. Secretly, everyone is just behind the Kouga kinjutsu scroll. Thobari is unable to understand why Miharu has defected to Kairōshū. The students of the academy attack the Kairōshū and Banten ninja at night.

Miharu tries to save Yoite, but Thobari doesnt approve of his using the Shinrabanshō and knocks him unconscious. Aizwa, seemingly immortal, rescues everyone. Before dying, the headmaster entrusts the kinjutsu scroll to Shijima who in turn gives it to Miharu.

Yukimi visits Hanabusa to search for Thobari. Upon finding she does not know anything, he eventually leaves. The next day, Raimei visits Kouichi, telling him she is helping Miharu obtain the kinjustsu Engetsurin. The pair are suddenly attacked by Yukimi. To prevent Yukimi from finding Thobari, Raimei leads him to the school. Unfortunately, Thobari is there. Thobari attacks both ninja, but Yoite stops Yukimi from fighting back. After a while, Yukimi decides to retreat and Yoite develops a high fever and is found to have discoloration and scars on his hands. Thobari then disappears completely. Hattori suspects Yoite and Miharu will rebel and moves on to the next step. Yoite and Miharu leave Hanabusas home.

Yukimi recalls how he met Yoite, while Gau and Raikou, along with Miharu visit Yukimi. Gau thanks Yoite, and he ends up staying with Yukimi. After, They both leave, looking For Oba, while it shows the Intelligence group."

Off in a room somewhere, Yoite wakes up to find himself bound and drugged, but is unaware of where he is. Back at the Kairoushuu hotel, Ichiki, the leader of the Tattegami, tells Hattori how Yae continues to ask about the annihilation of the Togakushi clan, but still will not answer their questions despite all the ninja techniques and medication they’ve used on her. Hattori decides to confront Yae to get her cooperation. Meanwhile, Raiko and Gau help Miharu and Yoite escape from the Tattegami.

Having brought Yoite and Miharu to Hattori, Yukimi uses the excuse of making the two repent to cover what he did. While Hattori explains how he convinced Yoite to learn the Kira, Raiko finds Ichiki, but before he can do anything he is attacked by Shiranui, the squad leader of the Tattegami. Elsewhere, Kouichi, Raimei, and Gau are attacked by the Kairoushuu ninja. Raiko injures Shiranui, and attempts to attack Yukimi. However, Hattori kills Raiko. Raimei and Gau leave Kouichi to fight off the Kairoushuu ninja, only to find out that Raiko is dead.

After killing Hattori, Yoite goes into a state of insanity and destroys Hattoris body with his Kira. Meanwhile the Shinra Banshou convinces Miharu to use her powers which results in him growing many times his normal size. Right as things are looking grim, Asahi, Miharus deceased mother, appears before Miharu in his mind and asks him to suppress the Shinra Banshou. Many days later, Miharu wakes up in a hospital bed safe and sound, only to find out that Yoite has gone missing. Miharu sets out to find, with Tobaris guidance, and ends up at a chapel.
