- Author Existence Failure: It's unknown if Takeshi Shudō ever actually did work on the planned third volume, and with his death in 2010, we may never know what he had intended.
- Early Draft Tie-In: The books essentially contain Shudo's semi-official headcanons on the universe and his wants for the anime, which go against most of what is actually depicted in the final product even the early episodes (for example, the samurai from episode 4 of the original series is replaced with a generic bug catcher and ten-year olds are still treated like kids in the anime).
- Keep Circulating the Tapes: The series is an obscure duo of Japanese-only light novels. They've never been rereleased and most likely never will be.
- No Export for You: The novels only came out in Japan.
