- Ending Aversion: Many people are frustrated because CLAMP never revealed the reason why Akira had two mothers or why his father left them (or, for that matter, why are his mothers so crazy).
- Just Here for Godzilla: The manga is one of CLAMP's most obscure works, and is mostly read as a curiosity by CLAMP School Detectives fans who want to know more about Akira's backstory. Otherwise, it's generally agreed to be a pretty intrascendent manga.
- Squick: A romance between a nine- and five-year-old is treated as Serious Business.
