Gameplay
Visual novel or "adventure game" elements are retained in the game, similar to the previous games, featuring sprites with limited animation, and text presented under the screen indicating their dialogue. There are apparently different sets of sprites for characters also different sprites for characters and interfaces during gameplay, moreover, some of the sprites are animated, instead of the usual static sprites found in the previous games.

Story
The game scenario is written by Kamachi, and is split in four stories: "Magic (Surface)", "Magic (Hidden)", "Science (Surface)", and "Science (Hidden)", with each story having a different protagonist. According to Dengeki Daioh magazine, it is also a lead in to the Toaru Majutsu no Index Movie, and introduces new characters to it. Kamachi personally wrote the "Magic (Surface)", while the other routes were discussed with him by the developers, referring to the route as the traditional "magician infiltrating Academy City," story. The story occurs before the Daihasei Festival Arc (Index).

The game takes place a few days "before the miracle began," referencing the movie's title. The game begins at their respective routes of the Science Side and the Magic Side, but later intertwine at a certain point. It is shown that there is a new magic cabal, The Gate of the Gods Come from the Heavens, among other things, like a Social networking service in Academy City, a contest, and a mysterious artifact known as The Ceremonial Fire of Agni.

Development
Early development of the game had the storyline revolve around Toaru Majutsu no Index exclusively, which what Bandai wanted initially. However, since the story of the game wasn't finished yet, and the fact that Kamachi's story for the movie included a lead in bit that didn't fit in the movie but Kazuma Miki didn't want to just throw it away. From that point on, the game had elements from Toaru Kagaku no Railgun added into it.
