Long thought to have vanished, ninjas resurfaced in modern Japan after the Pacific conflict. Rumors say about two hundred thousand of these lethal operatives now carry out clandestine missions, penetrating a large share of the country's public and private sectors. Within this cadre is Kurou Kumogakure, who usually lingers in a shabby flat with little drive to pursue anything. Many label him a hopeless drifter who merely pilfers beer from the neighbor. Yet the seventeen‑year‑old may prove far more perilous than his slack appearance implies. Kurou's concealed skill is challenged when he receives a fresh assignment to infiltrate a nearby high school, though the task holds twists beyond his expectation. The mission will test his resolve and force him to confront the shadows of his own past, revealing a destiny he imagined.
