Actor Allusion: The English dub created one by casting Spike Spencer, the English voice of Shinji Ikari, as Takuma, who protests that he doesn't want to climb into a giant mecha and is told that he mustn't run away.
The Danza: Yukari, the AI in Kurz's Arm Slave, is voiced by Yukari Tamura. This also partly crosses with Comic Book Fantasy Casting, since the original novels noted that Kurz intentionally modeled the AI on "a popular Japanese idol", even providing voice samples.
Too Soon: The name of Sōsuke Sagara's "home" country (Afghanistan) was changed in the anime and translation to a fictional country (Helmajistan).
Likewise, the second half of Fumoffu episode 1, in which Sōsuke (fakes) kidnapping a young boy to use as leverage against thugs who kidnapped Kaname, never aired on Japanese TV due to a string of kidnapping cases at the time.
