The Soukai Syndicate's resources seem to have no limits. Known for their scores of yakuza clones, they also have a number of ninja across Neo Saitama to handle their dirty business. Recently the cartel has been busy recruiting new talent to join their ranks. Two high school youths are in their sights—one an afro-wearing street punk with a death wish and the other a high school girl and former competitive origami champion.

Their head hunting might be for naught, for wherever ninjas lurk, Ninja Slayer awaits.
