- Unfortunate Implications -   [dead link] (NSFW) An odd plate number called 2MBOUT had made some Korean bloggers apeshit insane, because the letters 2MB stand for South Korean President Lee Myung Bak and hinted that he sucked and must go. However, Rideback is animated by a famous South Korean studio called DR Movie, so it is suggested that someone in the staff have deliberately inserted this. DR Movie denies this, of course, but someone who is ethnic Korean at Madhouse had probably tampered with the animation, or so the theory goes. It doesn't help that the voice behind Tamayo is a citizen of South Korea herself and she's also in the cast of an anime that made South Korean nationalists crazy.
