- Numata makes many shout outs to classic shounen titles as a result of reading too much manga.
- Yata also has a few to Star Wars, including a Darth Vader cellphone charm.Yata: wielding a lightsaber You'll find I'm full of surprises!
- The chapter with the otaku-bot in volume 7 features the Dragonslayer from Berserk, or at least a fragile plastic replica. Later on, that same bot is labeled "03", noted in the Disjecta Membra for that volume as a reference to Unit 03 from Neon Genesis Evangelion.
- At one point Numata references, of all things, Chick Tracts (specifically the "Here come de judge" line.)
