- Anime First: The manga adaptation was published a few days before the end of the anime series.
- Blooper: The English dub accidentally keeps a hilarious outtake in the official track for episode 18 when Fakir looks at a pile of papers, where he says he'll write a letter to the President. The Japanese version had him stay silent.
- DVD Commentary: Included in the North American and Australian releases of the show. Some are of the voice actors (and are usually goofy), but others include the staff that wrote the dub explaining some of the references in the show and choices they made during translation. One even explains how the packaging was designed!
- Fan Nickname:
- Fakir's often called Fail Knight by fans.
- Guitar Ninjas: anything which is unexpectedly and incredibly epic, though most often used in reference to the second season of the series itself.
- Mytho's tendency to have plot-relevant conversations with Fakir while wearing nothing but a nightshirt has resulted in him being christened the Pantsless Wonder.

- Portmanteau Couple Name:
- Real-Place Background: Gold Crown Town is heavily based on Nördlingen, a town in the south of Germany, known for its old buildings and almost fully intact city wall. Many local sightings make a regular appearance, like the town's church tower, statues, bridges and the water mill. The pizzeria appearing regularly is based on a real-life restaurant, and the town's five wall gates play an important role during the show's last act.
