Other mistake: When Sousuke checks Kanami out at the train station, the newspaper has its peephole on a different spot on the page depending on the shot. (00:07:25)
Other mistake: When Kurz patches Sousuke up, the band-aid on his shoulder is not visible in the back views, but in other angles it's drawn as it goes all the way to the back as well, so it should have been visible. (00:07:00)
Character mistake: Inside the Clockwork Orange-like machine, Kaname is being fed also misspelled words, such as "intrinsic", missing an "i", or nonsense like "phasenal". (00:02:25)
Trivia: The anime TV series, originally scheduled to debut on Japanese television in October 2001, was delayed in respect for the September 11, 2001 terrorist attacks in the United States. The Japanese release of an anime TV series about teenagers fighting international terrorists was considered tactless so soon after the attacks against the U.S. by international terrorists. It was released January 8, 2002, three months after its originally announced premier date.
