- B-Team Sequel: AIC was responsible for animating the first season. With producers Jiyū Ōgi and Chiaki Kurokane leaving AIC to help start Production IMS, all of the animation work was done for the second season and the film.

- Creator Couple:
- I Knew It!: A lot people correctly guessed that Reine Murasame and Phantom were the same person before Volume 16 confirmed it because they were both voiced by Aya Endo.
- Some other people reached the same conclusion for different reasons: the series follows Numerical Theme Naming, and Reine has the kanji for "zero" in can be formed by rearranging the two kanji in her name.
- Name's the Same: Ai, Mai and Mii are not to be confused for the yonkoma of the same name.
- The Other Darrin: from Season 3 onwards, Christopher Wehkamp replaces Alex Organ as the Big Bad Isaac Ray Peram Westcott because the latter retired and moved on to directing theater.
- Relationship Voice Actor:
- Azunyan and Sawa-chan Sensei from K-On! are back together again, this time respectively playing Kotori and Kurumi.
- Pheles and Wilhelmina are back from Shakugan no Shana and finally have a chance at fighting each other.
- Zechs and Treize are now indirect enemies, which is hilarious given Gundam Wing's late plot puts both of their organizations against each other.
- The dub as some of the shining examples:
- Tohka, Miku, Yuzuru (Megan Shipman), Mikie and Ai were once School Idols.
- It seems half of Team Natsu are gunning for Hughes' attention: Yoshino is Happy, Miku is Carla, and Kaguya is Wendy.
- It won't be the last time Josh Grelle (Shido), Brittney Karbowski (Kaguya), and Monica Rial (Mii) have been in a Harem anime which features Powered Armor.
- Star-Making Role: For Michelle Rojas in the English dub.
