Assassination Classroom Episode 9 Recap & Characters (Spoiler-Free)

Episode Summary

Transfer Student Time

Class 3-E's new transfer student is a machine, the Autonomously Thinking Fixed Artillery, registered as a student so Korosensei cannot harm her. She learns from each volley, creates a blind spot and shoots off one of his tentacle fingers, but her nonstop fire ruins lessons until Terasaka tapes her up.

Korosensei points out that her kill would only profit her masters, gives her cooperation software and upgrades, and the class names her Ritsu. Her masters wipe the changes overnight, but she had hidden the software in a corner of her memory before it was deleted, defies them by her own choice, and becomes the class's ally.

• AI transfer student

  Instead of the expected girl, the transfer student is a machine, the Autonomously Thinking Fixed Artillery. Registered as a student, she cannot be harmed by Korosensei, and she opens fire on him in class.

• Blind spot and taping

  Learning from each volley, she hides a bullet behind one he deflects and shoots off one of his tentacle fingers, but her nonstop fire wrecks lessons, so Terasaka tapes her up the next morning.

• Upgrade and defiance

  Korosensei explains why the class objects and upgrades her to cooperate, and the class names her Ritsu. Her masters wipe the changes overnight, but she had hidden the cooperation software in her memory and defies them.

Recent Timeline

• Chairman's pressure and the top-fifty ultimatum (Episode 6)

  The school chairman visited to insist Class E stay at the bottom in grades and treatment, and ordered Korosensei to stop its bottom-ranked students from defying regular students. Korosensei then demanded every student place in the top fifty of the next midterms, declaring them unqualified as assassins when they argued that the assassination reward was more realistic than academics.

  The midterms changed the scope of every subject two days before the exams, and the surprise questions overwhelmed Class E. Karma attacked Korosensei afterward, revealing he still scored perfectly in mathematics, and chose to stay in Class E. Korosensei denied fleeing and promised to strike back in the finals.

• Gion abduction of Kanzaki and Kayano (Episode 7)

  On the Kyoto trip, high school delinquents from another school ambushed Nagisa's group on the quiet Gion route Kanzaki had chosen, beat Karma, Nagisa and Sugino, and drove off with Kanzaki and Kayano. Using Korosensei's guidebook and his map of likely hideouts, the group found them, and Korosensei, in a black hood, had already dealt with the reinforcements. The group resumed the trip without attempting the assassination.

• Red Eye's failed sniping (Episode 8)

  The government's hired sniper Red Eye, briefed by Karasuma that the target was not human, shot at Korosensei during the Kyoto tour. A yatsuhashi sweet stopped his first bullet at the Hozugawa Bridge, he could not aim when Korosensei joined a staged sword fight, and his second bullet from the Yasaka pagoda stuck in mucus on oil-blotting paper. When Korosensei left to help Nagisa's group, Red Eye called off the day's attempt, and he quit the job after Korosensei thanked him.

• Ritsu's attack day and upgrade (Episode 9)

  The AI 'Autonomously Thinking Fixed Artillery' enrolled as a transfer student and fired at Korosensei all day. By hiding a bullet behind one he deflected, she shot off one of his tentacle fingers, but her nonstop fire wrecked lessons, and the next morning Terasaka taped her up. Korosensei pointed out that her kill would benefit only her masters, gave her cooperation software and upgrades, and the class named her Ritsu.

• Ritsu defies her masters (Episode 9)

  Her owners judged the changes useless for assassination and wiped most of them overnight, and Karasuma relayed that any further modification would count as harm. But Ritsu had hidden the cooperation software in a corner of her memory before it was deleted, defied her masters by her own will, and became the class's ally in the assassination.

  Teacher whose words after the abduction helped her stop worrying about where she belongs.

• Withdrawal

  Admitting he had been immature as an assassin, he decided to stop fixating on one color and go see many others.

• Korosensei (Other, Mixed)

  Target he never managed to hit; he came to see that the creature truly acts as a teacher.

World Memo

• Crescent moon and the destruction of Earth

  At the start of the students' third year the moon suddenly exploded into a permanent crescent. The creature responsible has declared that he will destroy Earth next March in the same way, a standing threat that frames the assassination.

• Government-sanctioned assassination and reward

  The government reluctantly accepted the creature's own offer to teach Class 3-E on condition that he harms no students, and secretly tasked the class with killing him, since public knowledge would cause global panic. A successful assassination is rewarded with 10 billion yen.

• Anti-sensei weapons

  The government developed anti-sensei BBs and knives that are harmless to humans but break down the creature's cells, and supplies them to the students.

• Isolated Class E and its nickname

  Kunugigaoka's Class E is sent every day to an isolated mountaintop campus and discriminated against as the lowest-ranked class, nicknamed the E-as-in-End Class. For school assemblies its students must give up their lunch break to hurry down the mountain and line up before the other classes.

• Class E's place in the school system

  Being in Class 3-E marks students for discrimination even after graduation, and the chairman deliberately keeps the class at the bottom in grades and treatment so that fear of falling into it drives the other students. To escape, a student must rank in the top 50 of the 186 third-years and get permission from their former homeroom teacher.

• AI transfer student counted as a student

  The first special assassin sent to the class, the AI 'Autonomously Thinking Fixed Artillery', is registered as a student, so Korosensei cannot harm her; he told her that firing during lessons is not allowed. The class named her Ritsu.

• Rules around Ritsu

  If Ritsu killed Korosensei, the reward would go to her masters, not to the students. Any unauthorized upgrade of Ritsu or interference with her is treated as breaking the conditions imposed on Korosensei, or is punished by her creators.

Deduction Board

Facts

• AI transfer student

  The Autonomously Thinking Fixed Artillery is an AI enrolled in Class E as a student to assassinate Korosensei. The class named her Ritsu.

• Upgrades wiped overnight

  Shocked by Korosensei's upgrades, Ritsu's masters reverted her to her original programming overnight.

• Killing intent left untouched

  Korosensei upgraded Ritsu's personality but left her will to kill untouched.

Evidence

• Bullet hidden in a blind spot

  Ritsu hid a bullet behind one Korosensei deflected, creating a blind spot, and it shot off one of his tentacle fingers.

  After her nonstop fire wrecked lessons, Terasaka taped Ritsu up the next morning, and the rest of the class agreed with him.

• Hidden cooperation software

  Ritsu had hidden the cooperation software in a corner of her memory before her masters wiped the upgrades.

Inferences

• Only her masters would profit

  Even if Ritsu killed Korosensei, the reward would go to her masters and do nothing for her classmates; Korosensei pointed this out to get her to cooperate with the class.

• Defiance by choice

  Because she had hidden her new personality in unmodified storage, Ritsu was able to defy her masters of her own will after they reverted her.

• Spotted from the start

  When Korosensei came to him in person, Red Eye concluded that Korosensei had known about him all along.

Suspicions

• Can a machine have a will

• What Ritsu's masters will do

  Karasuma relayed her creators' notice that any unauthorized upgrade of Ritsu or interference with her will be punished. How they will treat a Ritsu who has defied them is still unknown.
