Talk:Toaru Kagaku no Railgun OVA/@comment-2249936-20130227154732/@comment-49.145.95.79-20130227161151

The summer in the anime universe of Index and Railgun is seemingly extended for covenience's sake so original stories can be fit with ease without utterly ruining the timeline. This is the reason why the anime has the OVA, the Poltergeist Arc, and the storyline for the Toaru Kagaku no Railgun PSP game. Furthermore, the Index Arc in the anime adaptations is moved further into the timeline, as such, necessitating for two blackouts caused by Mikoto.

The OVA happens most likely after the Level Upper Arc and before the Index Arc and Poltergeist Arc.
