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, there's more to Kouichi and Kumohira then meets the eye.

Now a part of the nindou club, Miharu continues his indifferent ways and doesn't really participate in training. Much to Kouichi's and Kumohira's disappointment. When a girl samurai named Raimei Shimizu comes to see if Miharu would be a good ruler of Nabari, she finds it hard to believe that Miharu is the one she is looking for.

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?

After chasing Yoite off, Kotarou has the remaining Fuuma ninja treat the wounded while he makes up causes of death for the dead. Thanks to the Fuuma ninja, Miharu's group is treated of their injuries and even Kumohira is saved. Later, after everyone has gathered before Kotarou, Miharu learns of the past of the Shinrabanshou and what will happen to the user if it is removed.

Finally back in Banten, Miharu, Kouichi and Raimei destroy Banten's ninja skill books. Later, trouble arises when Miharu's 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 she's after, can she kill him?

After regaining consciousness Raimei and Kouichi begin searching for Miharu. After not being able to find him, they seek out Kumohira, who has just arrived in Banten. Although Kumohira wants to search for Miharu immediately, Kouichi points out how he and Raimei are still alive, so Miharu is too. Elsewhere, Miharu learns Yoite's wish that only Miharu can grant him.
