アンダーニンジャ
Once believed to be extinct, ninjas have reappeared in contemporary Japan following the Pacific War. With a headcount rumored to be two hundred thousand, these deadly assassins are now tasked with covert operations, infiltrating a significant portion of the nation's public and private institutions in the process. Among these ninjas is Kurou Kumogakure, who often spends his days in a run-down apartment with no motivation to do much of anything. Some might consider him a useless vagrant who does...
A seemingly lazy 17-year-old ninja undertakes dangerous infiltration missions in contemporary Japan, revealing a hidden world of assassins embedded in society. The seinen tone brings grittier action and moral complexity than typical shonen fare.
