Plot
The background is set primarily at Dengeki Academy, a Japanese private school where the main characters attend. The story revolves around an unnamed protagonist who one day hears a recent rumor that a ghost has been appearing during the night at school. While he does not have any real interest in the occult, he uses searching for the ghost as an excuse to sneak into the school campus one night. However, his childhood friend Kizuna Kasugai comes with him to search for the ghost, and the two decide to search around the bench in front of the campus store. In the silent darkness, the two gradually arrive to open the door of the store and before them they see a person's shadow move in the room. By straining his eyes, the protagonist sees that the person casting the shadow is eating melon bread, and realizes that this must be the cause of the ghost rumor; the shadow is in fact cast by Shana from Shakugan no Shana. This is possible due to one day the reality-based world of Dengeki Academy and the worlds of the Dengeki Bunko light novels to suddenly become connected allowing people from both the real-world and the novel worlds to cross over.

By meeting Shana, the protagonist and Kizuna become entangled in a struggle by the members of the novel worlds to protect their worlds from the unidentified evil organization known as Zetsumu (絶夢) who have been changing story details from the novel worlds and creating disorder in them. Their goal is "to snatch away the smiles from every person". In order to combat Zetsumu, the protagonists will help the fighters from the novel worlds by travelling between the real-world and novel worlds.
