- Author Existence Failure: The original story creator, Sunao Yoshida of Trinity Blood fame, died in July of 2004, so even if it did get released on schedule, he would've been dead for about a year.
- Development Hell: First announced to be in production in 2003, gets released in 2013. TEN YEARS LATER!
- What Could Have Been: In the originally planned 2005 movie, the main characters would've been 3 characters named Mikoto Ikeda, Nene Swarovski, and Hitage, voiced by Ryoko Shintani, Sakura Nogawa, and Yae, respectively. Mai Kadowaki was also to play an unknown role. Incidentally, Chihiro Suzuki, Kosuke Toriumi, and Tomo Saeki, who were also going to be in the original production, still got into the new movie.
