[Machine Translation] Death to traitors. Dissonance runs through the huge ninja organization "NIN"! A modern-day ninja tale by Kengo Hanazawa of "I Am a Hero" fame! A ninja attack incident broke out in Nerima Ward. Suzuki, a ninja, and Pure Ai, an elementary school student, are targeted by the attackers, but they realize that the attackers have a personal connection with Suzuki in the past, and they dare to let him live in this place. Later, the culprit is clad in a fully transparent Marishiten, leading to the suspicion of Onikobe and Chunin Kato, both of whom had been overseas shinobi, by NIN. Meanwhile, Kumogakure Kuro senses a battle with a powerful enemy that will take place on the day of the attack on the Yankee High School, and quietly prepares for it.
