Ep. 9: Siswa Pindahan Waktu

Upon returning from their class trip, Class 3-E are greeted by their first transfer student, an AI-powered machine known as the Autonomous Intelligence Fixed Artillery who uses calculations to adjust the accuracy of her attacks. However, the class gets sick of her constantly firing her weapons during class, deciding to tape them shut themselves so they can study properly. Wanting the AI to get along better with her classmates, Koro-sensei makes some modifications to her hardware and programming, giving her a more human personality that her classmates, who nickname her "Ritsu," come to accept a lot more. Later that night, Ritsu's creators, who are less than happy with the changes, remove all the modifications that Koro-sensei made and forbidding any further changes or tampering. However, Ritsu manages to hide her new personality from them before it is deleted, deciding to secretly defy her creators for the sake of keeping her promise to help her classmates.
