## Trivia

* Sekigahara's story was inspired by the science fiction films *Total Recall* and *Solaris*. It also took inspiration from the episode titled "Demon with a Glass Hand" from the American TV series *The Outer Limits*, although it underwent some changes.
* Writer Watanabe Kouji has stated that his favorite scene in the game takes place within Sekigahara's last event, Event No. 281: Piercing Ambition. He proclaims this to be a scene that will leave a mark in the history of science fiction.
* Ei does not appear in the ending cutscene that happens while the credits are rolling.
* Because Iori Fuyusaka's story was originally intended to be more like a shoujo manga, with Sekigahara deciding whether he was interested in Iori Fuyusaka or Ryoko Shinonome, the way he refers to Shinonome is very inconsistent, as that is a remnant of that original idea.
* In the epilogue, Iori Fuyusaka refers to Sekigahara as あの人 (*ano hito*) ("that person"), which is commonly used by a married woman to refer to her husband.
* While it was not shown on-screen, George Kamitani says that Sekigahara would've returned to see Fluffy one last time in order to get shot with the Magical Gun.
* Sekigahara's school uniform not having any buttons was from the developers originally thinking of Sakura High School having different uniforms in the 2060s.
