King of Nabari

Rokujou Miharu, a 14-year-old high school student, possesses the powerful hijutsu "Shinrabanshou" technique, a highly sought-after skill in the ninja world of Nabari. This has made Miharu a target for various ninja clans seeking to claim his ability for themselves. To protect Miharu, his classmates Kouichi and English teacher Kumohira, who are secretly from the Banten clan, try to convince him to join their group. Miharu initially rejects their offer, but eventually accepts their invitation in order to ensure his safety.
