Trivia: Mayo Chiki!
- Relationship Voice Actor: Almost all of the voice actors have been in the To Aru universe:
- Subaru as Index, Jiro as Shiage, Kureha as Erii, Usami as Lucia, Nakuru as Hyouka, and Nagare as Kihara.
- Kanade and Kureha have been together many times before: Mairu and Anri, Yui and Tenshi, Izumo and Shiemi, Karen and Nadeko, Akeru and Yuuka, Tatiana and Holly, Sunao and Potemayo, Ganessa and Lana, and Akane and Kagari.
- Karen and Tsukihi of the Fire Sisters in Bakemonogatari are now master (Kanade) and servant (Subaru) respectively, with Nadeko (as Kureha) having a crush on the latter.
- Too Hot for TV: As expected, the Blu-ray release of this series ups the fanservice, although Barbie Doll Anatomy appears to still be in effect.
