- Better Than It Sounds: Incestuous siblings try to escape their abusive family (which is also the wizard mafia), ponder the flaws of their country's education system, and try not to cause the apocalypse.
- Jossed: Because Kokoa had the features of both Shiba siblings or even directly looked like a loli version of Tatsuya, many fans thought she was the daughter of Tatsuya and Miyuki, or even his clone.
- Fan Nickname:
- "Japanese DragonProudSky" for Tatsuya in the Chinese ACG community.
- Jesus-sama - Also Tatsuya because of his "resurrection" ability and divine allusions in work.
- The Mime - Mikihiko for those who can't remember his name.
- Boobs - Mizuki. Again, an Inherently Funny Word for those who can't remember her name.
- No Dub for You: Aniplex USA didn't dub the series for its North American release because of the fiasco involving the anime's fanbase.
- Take That, Audience!: In one of the arcs, the author introduces Minoru Kudou, a genetically modified mage who was born from the parents who were full siblings. And although he is also incredibly beautiful and strong in magic, like Miyuki, incest has made his genes unstable, and his health is extremely weak. The story of the character looks rather embarrassing, as at that time none of the fans of Miyuki-Tatsuya knew about her gene modifications. Moreover, since Mamoru was also modified, it becomes pretty scary for the offspring of Shiba siblings.
