The ninja organization in Japan, which once flourished, was dismantled by the GHQ after the Pacific War and disappeared. However, the ninja still exist in secret, and it is said that there are 200,000 of them living in Japan today, hiding and working in the dark in the public and private sectors and in all kinds of organizations. While some of the elite ninja work behind the scenes in national level conflicts, the ninja at the end of the line are often unable to find work. One of them, Kuro Kumogakure, who is living the life of a NEET, receives a serious "ninja assignment," an order from his superiors to infiltrate a high school with the latest equipment.
