Trivia / Abunai Sisters

• Creator Backlash: Production I.G. seems to be ashamed of this series, as it has not been rereleased after its 2009 premiere.
• Keep Circulating the Tapes: Only the first two episodes aired on TV, with the rest being released on DVD; even then, the soundtrack apart from the intro is pitched up, though a version in the correct pitch exists. Said DVD is long out of print, and not many copies were printed.
• One-Book Author: Leni Char (who voices Hokuroda) has no other credits on her IMDb page.
• Reality Subtext: Supposedly, the inspiration for the show came when the Kano sisters showed up an at event (overseas) and found no one knew who they were.
• Short-Runners: Ten episodes were made, with only the first two airing. The whole series is ten episodes long.
