Anime and Manga Differences

 * The Anime adds multiple Flashbacks of Nasu Squad.
 * the Anime adds a scene where Karasuma jokes saying that Kumagai has an additional trigger called "punch rocket" which launches her arms using trion, which it was supposedly made using aftokrator's technology.
 * the Anime adds a small clip where Yōtarō says fights are all about guts when Tachikawa says the amount of spirit you have doesn't matter.

Debatable Canon

 * During the last Nasu Squad flashback Akane has, we see a clip of Akane introducing herself to Nasu, Kumagai and Sayoko as if she was just promoted but Akane, Nasu and Sayoko all enlisted at the same time with Kumagai joining a little before them. So it is unknown if that is how Akane actually reacted as there is a high chance they have met beforehand and/or actually know each other before their promotions.
