Animation Trivia


Comparison of Misaka Mikoto's phonecall.
Top: Scene from the Comiket 94 PV. Bottom: Scene from the episode.

  • The scene where Misaka Mikoto tells Touma via phone that Academy City has intervened in Avignon is taken from a scene from the PV of the Toaru Majutsu no Index III anime shown Comiket 94. However, instead of daytime, the scene in the episode proper is accurately shown to be nighttime due to the different timezones.
  • The brief fantasy scene showing Index being the reason for Touma is taken from episode 4 of the first season of the Toaru Majutsu no Index anime.
