A series of short stories in the world of Toaru Majutsu no Index organized into chapters featuring Kanzaki Kaori as the protagonist, going around the world and space doing missions for the Church of Necessary Evil, however, there is more than meets the eye as each incident is connected.

One chapter was bundled with each limited edition release of the Toaru Kagaku no Railgun anime DVD and BDs, with all of them together being equivalent to a single normal Toaru Majutsu no Index volume

Mu Chun, who woke up after a burst of dizziness, didn’t know whether he had entered another personality or another universe.

The eldest daughter of the lawyer family told Mu Chun that he was the most promising inheritor of the school of psychoanalysis and the most gifted therapist.

This era is also very strange. All kinds of physical and mental diseases can be seen everywhere, such as mania, insomnia, dysfunction, persecutory delusions, transvestism… emerge one after another, but the treatment methods stay in the era of psychoanalysis.

Mu Chun just wanted to keep her own law and order, earn money to support her family, and coax the eldest lady to go home to become a lawyer, while she was dawdling in the community hospital.

The eldest lady stalked him to become the greatest therapist.
