* ActingForTwo:
** Ritsu Takarada and Jun Samukawa, as well as the younger Shu Ouma, are voiced by Creator/MinamiTsuda.
** The younger Gai Tsutsugami and Miyabi Herikawa are both voiced by Creator/AkenoWatanabe.
** Inori Yuzuriha and Mana Ouma are both voiced by Creator/AiKayano in Japanese and Creator/AlexisTipton in English. This makes sense later on [[spoiler:when you find out that Inori is a clone of Mana, so it would make no sense at all if they had different voice actors]].
* AnimeFirst: Started as an anime original, then adapted into written materials.
* ChannelHop: After ''Guilty Crown'' first aired on Creator/FujiTV, reruns aired on Fuji TV Two from November 2012 to February 2013.
* CreatorCouple: Creator/TerriDoty, who voiced the younger Gai in the English dub, is married to Stephen Hoff, who was the ADR engineer.
* {{Defictionalization}}: Supercell assumes the name Egoist whenever Chelly is doing vocals. [[http://www.egoist-inori.jp/ Yes, it's more or less a real band under an actual label.]]
* DirectedByCastMember: Besides directing the English dub, Creator/ColleenClinkenbeard was one of the additional voices.
* NonSingingVoice: Creator/AiKayano voices Inori, but does not do the singing voice for her character, even though she has done songs for other anime she's been in. Instead, Chelly of Egoist does Inori's singing voice.
* NoExportForYou: The manga version, ''Lost Christmas'' visual novel (including the OVA), ''Princess of Deadpool'' and ''Dancing Endlaves'' did not have an overseas release. However, the ''Lost Christmas'' visual novel received a fan translation in 2016.
* WrittenByCastMember: Creator/PatrickSeitz, the English voice of Dan Eagleman, wrote the scripts for episodes 7, 8, 13, 15, 17 and 19.
