## Trivia

* Hyperdimension Sephira was originally a roleplay that started in mid to late 2015 on a site called Anispace. The original roleplay had handled its plot somewhat differently and had many more characters including those from Star Wars. Those characters were removed and were either set to appear in another series, to appear in a later arc, or removed entirely.
* Characters like Shizuki. Inori and Sayuki were conceptulized before Sephira but was never used or introduced in anything else before.
* Sephira was originally to be a Neptunia/Date a Live Crossover
* Shirou Emiya was to be the protagonist of the Nep/DAL crossover as a third entry into the discontinued Sword of Origin Series.
* As of late September of 2018, Sephira was announced to get a redux after the release of 5 episodes/chapters. This is partly due to the creator's discontent with how he handled a few of the episodes. The Sephira redux would be very different from the first five episodes currently released and would introduce a new villain, replacing Thane Schwarzer.
* Even though the redux was stated it would not change what was already planned for the rest of the series going forward by much, it does call the future of the *Nemesis Imperitive* arc into question, as its main antagonist is connected to Thane Schwarzer.
