- Actor Allusion: This is not the first time that Chris Patton played the role of an Otaku.
- Defictionalization: Believe it or not, the eroge made in the story was later made into a tie-in videogame, with a story by the author himself.
- Keep Circulating the Tapes: The manga and light novel were licensed by Tokyopop. The manga sold reasonably well, but fell out of print after TP shut down, was not rescued by anyone, and volumes are increasingly difficult to find even on the used market. The novel had only a small print run, and tends to command a ridiculously high price on the rare occasion it appears on retail/auction sites.
- The anime, by contrast, is much easier to find, especially if you're in the USA, since Funimation uploaded the entire thing onto its website (and for non-Americans there are... other methods).
- Name's the Same: No, it's not the TV network NHK.note
- Reality Subtext: See Author Avatar. Also, Chris Patton (who played Satou in the dub) has struggled with anxiety problems for most of his life, which likely helped him in the role. His performance in the dub has been highly praised by critics.
