In the shadows of this modern world, ninjas fight for control of an ancient technique which holds untold strength. This coveted power dwells within apathetic
Miharu, a fact the guy really couldn’t care less about – until the clashing rival clans bring their battle to him.
Now Miharu struggles to understand the mystery buried in his soul, and must choose a side if he hopes to survive. But when conflict is waged in secret, and lethal ninjas hide in plain sight, friend and foe prove difficult to tell apart.
Silent, apathetic, yet mischievous, 14-year-old Rokujou Miharu is the bearer of the hijutsu, “Shinrabanshou,” a powerful technique many ninja clans desire to possess to become the ruler of Nabari. Fellow classmate Kouichi and his English teacher Kumohira are both secretly Banten clan ninjas, pledging themselves to protect Miharu from his many attackers. Keeping apathetic, Miharu attempts to reject their invitation to join their ninja “club.” However, after numerous attacks, he finds no choice but to join their group as a means for his survival. Slowly, Miharu takes a step closer to becoming the ruler of Nabari.
There are two worlds which exist side by side – the ordinary surface world of the humans and the secret world of ninjas called Nabari. Within this secret world, the opposing ninja groups are fighting over who should possess the ultimate power known as Shinra Banshou. Enter Miharu Rokujou, a high-school student who lives a carefree life and likes to keep himself to himself. Unfortunately for Miharu, his carefree life is about to be over, because within him is hidden the ultimate power and there is no end of evil minions ready to kidnap him for it! Miharu’s only chance of survival is to embrace this mystic world and become the King of Nabari himself. With the help of his new ninja friends, Kouichi, Shimizu, and Kumohira, can he come to grips with his powers or will he fall prey to his many enemies instead?
