Talk:Toaru Kagaku no Railgun (PSP game)/@comment-76.73.223.61-20151111024139/@comment-26527700-20170801153242

Debateable. I'd say that how canon the events are considered depends on how canon you see the Railgun anime as being realtive to the manga. For example, the manga introduces Kongou Mitsuko nearly a month and a half in-universe time later than the anime. She doesn't show up at all until after the Sisters arc. The anime has her in the first episode.

Based on this, the game fits in with the anime's narrative but not the manga's. If you hold that the anime retconned the manga, then this could be canon. If you hold that the manga is the ultimate canon and the anime is only semi-canon at best, the game can be little better.

Alternatively, you could hold that both are canon and that the events were altered by the incident from the Index PSP game.

EDIT: Since writing this, I have learned that at mininmum the Disciplinary Guides from this game were mentioned by Uiharu during chapter 47 of the manga, who read about them on an urban legend site. This could place the PSP game as happening after the Daihasesai Arc.
