* AnimeFirst: Manga adaptation by Ryou Akizuki.
* KeepCirculatingTheTapes: After Creator/{{Geneon}} went under, this series has yet to re-enter print, and it doesn't help that the box sets are expensive. Though the individual [=DVDs=] can be obtained cheap.
* RelationshipVoiceActor: This isn't the only time Creator/MichelleRuff played a character that is so good that the character played by Creator/JulieAnnTaylor attempted to challenge her [[spoiler:which almost got her killed]], and [[{{Manga/Bleach}} Rukia and Lirin are just like that]].
* WhatCouldHaveBeen: The third part of the series was intended to explain Kouta's abilities in greater detail.
