"Angel Fall" (御使堕し(エンゼルフォール) Enzeru Fōru?, lit. "Fallen Messenger") is the 15th episode of the Toaru Majutsu no Index anime series and the first episode of the Angel Fall Arc. It was broadcast on January 8, 2009, and was directed and storyboarded by Nakatsu Tamaki, and the script written by Minikami Seishi. The opening theme masterpiece, does not replace PSI-Missing during this episode, and is later moved for episode 17. This mistake is later rectified in the DVD and BD releases of the anime.
