Nabari no Ou - S01

Fourteen-year-old Rokujou Miharu is quiet, indifferent, and a little mischievous. He possesses the "Shinrabanshou," a hidden technique coveted by ninja clans who seek to rule the land of Nabari. His classmate Kouichi Aizawa and English teacher Thobari Durandal Kumohira-both secretly ninjas of the Banten clan-swear to protect him from the constant threats. Miharu, still disinterested, tries to refuse their offer to join their ninja "club," but after relentless attacks, he has no choice but to accept for his own survival. As he reluctantly becomes involved, Miharu edges closer to his fate as Nabari’s ruler.
