Differences in Adaptation

  • The anime didn't adapt the part when Mikoto first considers asking Shokuhou Misaki to fix Kamijou Touma's memory loss problem, but quickly dismisses the idea since she isn't on good enough terms with her, and Mikoto did not want to end up in the "Queen's" debt. Mikoto also did not like the idea of trusting the health of a friend to someone she has an indirect rivalry with.

Animation Trivia

  • After Tsuchimikado and Touma agreed to split up and Saigo began chasing the latter, Saigo's model of him chasing after Touma is simply an enlarged version of him from the distance. As such, Saigo looks blurry and of poor quality.
  • When Isahaya walks back to Tatemiya, he is closing and opening the scissors he is holding over and over again. However, the scissors are animated only once while the scissors can be heared opening and closing twice afterwards.
  • As Misaka goes down the stairs thinking about Touma's amnesia, the animation of her going downstairs is just her cel being moved up and down as the background cel is moved behind her.
  • After Touma orders Index to clean the bathroom, he looks at Itsuwa continue cooking. Itsuwa is off-model.
  • When Maika barges into Touma's apartment and says she smells something, her mouth doesn't move.
