Under Ninja

Ninjas, once thought to have vanished, resurface in post–Pacific War Japan and quietly embed themselves throughout society. Rumored to number around 200,000, they operate from the shadows, carrying out covert missions while infiltrating both government bodies and private organizations.

Kurou Kumogakure is one of them—an unmotivated 17-year-old who drifts through life in a shabby apartment and is dismissed as a deadbeat, even accused of swiping beer from a neighbor. That listless image masks something far more dangerous, and it’s tested when Kurou receives orders to go undercover at a nearby high school—an assignment that quickly proves more complicated than it first appears.
