Trivia / Ninja Nonsense

• Keep Circulating the Tapes: The manga. The first three volumes can be nabbed without too much trouble, but the fourth volume was cancelled.
• Otaku O'Clock: The show was meant to be watched by men who had nothing to do late at night.
• What Could Have Been: As said on the main page, Word of God had planned for "Dark Shinobu" from the opening credits to actually appear in the series and be a Knight of Cerebus, but limited budget and no further episodes made her nothing more than a Bait-and-Switch moment to make the show seem like it'd be more serious than it really is.
