Trivia

 * Though the content itself does not change, several visuals of the ending theme video displayed during the end of an episode has been edited, and has been used beginning on the 9th episode of the second season of the anime until it's replacement by the new ending theme. These changes are mostly notably Touma's face and Index's walk animation near the end.
