The scene flashes back to two months earlier, where an unemployed high-school dropout named Kurō Kumogakure is given a modern ninja hoodie along with orders to infiltrate a local high school. After helping out his neighbor Kawado, and giving her some beer that he stole from another neighbor named Ōno, she agrees to pose as his mother to enroll him in the school. Meanwhile, a Russian man loudly tries to meet a ninja on his own. 2 "I Want to Be a Ninja" Transliteration: "Watashi wa Ninja ni Naritai" (Japanese: 私は忍者になりたい) Taiji Kanawashi Keiichirō Ōchi Satoshi Kuwabara October 13, 2023 (2023-10-13) In the present, Kuro continues his duel with a high school girl from an opposing school. Back in July, the Russian man finds a torii scrawled on a utility pole with a message nearby warning people not to piss in public or their dicks will be cut off. The Russian's handler tells him to find and infiltrate a ninja clan in order to keep his baby daughter alive. Thinking the message is a ninja code, he begins to cut off the dicks of anyone pissing outside nearby. However, he starts to build a reputation as the Nerima Slasher, especially after a failed attempt to attack a gross man who turns out to have real ninja skills and a fake dick. Kuro is then given the assignment by Kato to find this Nerima Slasher and take him out. As a young girl manages to find the Russian hiding under a shrine, Kato and Sasama talk about the current state of ninja affairs. 3 "Boobs: So Close, Yet So Far" Transliteration: "Oppai wa Chikakute Tōi Sonzai" (Japanese: オッパイは近くて遠い存在) Mie Matsushima Keiichirō Ōchi Satoshi Kuwabara October 20, 2023 (2023-10-20) In the present, Kuro injures his opponent's arm by slamming it into a railing, while one of his teammates attacks her gyaru allies. Back in July, Kuro set a trap for Kawado's bra thief, only to find it was a high school boy. After covering for him, Kuro deputizes the boy to help him find the Nerima Slasher, and the boy later hands the task to a little girl at his apartment block in exchange for letting her fly his drone. Some time later, the girl finds the Russian man and takes him to her apartment, then shows him to the boy to play with the drone. The boy then tells Kuro, but the message goes out to multiple ninja in the area, who all converge on the same apartment block to take out the Russian man. 4 "Do You Know What the Ninja Code Says?" Transliteration: "Shinobi no Okite wa Wakatteiruna?" (Japanese: 忍びの掟は分かっているな？) Satoru Yamashita Keiichirō Ōchi Wataru Chihara October 27, 2023 (2023-10-27) In the present, the ninja successfully neutralize their rivals while Shion tries to make up with their leader in the nurse's office. Back in July, the Russian man manages to fight off two ninja opponents and steal the kei car of an abusive father, sparing him at the last minute when the little girl at the apartments cries out. However, the Russian man is knocked out by an invisible Kuro, and then escorted to a meeting with more senior ninja. Sasama takes off his suit and reveals his true form to be that of a skinnier woman. The ninja send a couple assassins to rescue the Russian's daughter and kill his handler, informing him that they have recruited him into their foreign affairs division. 5 "Kumogakure Is Within the Top 10 Common Family Names in Japan (Lying)" Transliteration: "Kumogakure wa Nippon de Oi Myōji Rankingu Ichi Zero iinai（Uso）" (Japanese: 雲隠は日本で多い名字ランキング１０位以内（嘘）) Shintarō Matsui Keiichirō Ōchi Igumikyia, Satoshi Kuwabara November 3, 2023 (2023-11-03) Kuro takes the entrance exam to enter the high school for his mission, with Shion's sending him coded test answers using colored grains of rice stuck between the floorboards. However, his classmate Noguchi, who is there to take a make-up exam herself, notices the rice and alerts the teacher, forcing Kuro to take drastic measures to pass the test before his plan is ruined. Afterwards, Kuro invites Noguchi to his home to meet his "mother" Kawado, where they watch a bloody show from the Ninja Broadcast Company. The next day, Kuro heads to school with Eita and Noguchi. After a strange encounter with the school Director, Kuro helps Eita deal with some bullies. 6 "The Lid on This Hellish Cauldron Has Come Off" Transliteration: "Jigoku no Kama no Futa ga Ima Hiraitayo" (Japanese: 地獄の釜の蓋がいま開いたよ) 蟹久保朱眞 Keiichirō Ōchi Satoshi Kuwabara November 10, 2023 (2023-11-10) 7 "Meow Meow, Meow Meow, Meow Meow Meow Meow Meow?"
