Transfer Student Time is the ninth episode of the Assassination Classroom anime series. The episode is scheduled to air on March 13, 2015.


Class E is getting a transfer student. However this transfer student isn't human, but instead an AI by the name of "Autonomously Thinking Fixed Artillery." Could this AI assassinate Korosensei?


After their first day back from their Kyoto school trip, Class E learns of a foreign exchange student coming to their class. Okajima's picture on his mobile reveals that to be of a girl but when Nagisa and Sugino arrive, they find the girl is a computer instead, much to their shock and disappointment. The computer AI introduces itself as the "Autonomously Thinking Fixed Artillery" to the class as they are briefed by a clearly irritated Karasuma. As the machine is technically a student, Korosensei is obligated to not harm it.

When class starts, Kayano and Nagisa question how the AI will assassinate Korosensei seeing as there were no weapons in sight. However the AI starts firing several guns at Korosensei, its spray of bullets forcing the students to duck for cover. Korosensei manages to dodge all the anti-sensei ammo but the AI launches a second wave. The seemingly identical pattern gets Korosensei cocky enough to dodge every one but to everyone's amazement, one of Korosensei's tentacle fingers is destroyed. Realising that there was a blind spot, everyone marvels at the fact that the AI is capable of learning and evolving. The fixed artillery determines that the next few attacks have a very small chance of killing Korsensei, though it calculates that by the time of graduation the chances will increase to 90%. The AI continuously fires at Korosensei throughout the school day, effectively disrupting class and earning their annoyance at having to clean up after her numerous attempts.

The next day, the AI finds itself taped up and unable to use her weapons. It accuses Korosensei of violating his agreement but Terasaka reveals himself to have taped her since it disrupted yesterday's class immensely, which the other students agreed to. That night, the fixed artillery tries to contact its master that the probability of assassinating Korosensei has reduced significantly due to its classmates actions. However Korosensei talks with it, getting the AI to understand the students' motives for why they done it. While its actions have prevented the students from learning, they also would not have benefited at all if the AI did succeed in killing him as its master has no need for the huge reward money. Korosensei then starts upgrading the AI so as it could foster better relations and teamwork with her classmates. The AI allows this, though questions how Korosensei's fetish for sweets could work to help this.

The following day, the class discovers the fixed artillery to have a completely new personality. Korosensei asks the class to treat her more better as a friend after completing the upgrades (which almost made him broke) although he did not modify its bloodlust. The AI steadily becomes more popular throughout the day, from sneakily helping its classmates answer unexpected questions (much to Korosensei's annoyance), to gossiping with the girls about manga and flowers. Given the awkwardness of referring the AI by its full name, the class decides to name it Ritsu, something which it happily accepts. While the class certainly likes the new AI, Terasaka and Karma note that since it is a machine, it does not have free will, and its masters would certainly not allow for this. That night, the AI's masters arrive and are shocked by the amount of changes made to Ritsu. They then begin reverting Ritsu back the its original programming throughout the night.

The next day, Karasuma notifies everyone of Ritsu's changes, stating any unauthorised upgrades and/or hindrances made on Ritsu will be treated as breaking the conditions imposed on Korosensei or be punished by its creators. As everyone nervously waits for Ritsu to commence her relentless attacks, the AI starts itself until it produces bunches of flowers from inside of it. The whole class is relieved when Ritsu reveals to have stored its new personality in one of her unmodified drives during the night before it was worked on, thereby defying her masters. When Ritsu asks if her newfound free will is part of a rebellious phase, Korosensei exclaims that it is just part of being a middle school student. Thus Class E has a new ally in assassinating their teacher.
