* AnimeFirst: There is a manga, ''Kiddy [=GiRL=]-AND Pure'', which was released simultaneously (it actually started serialization in Comp Ace before the anime started) but the story differed wildly. A novel adaptation was released later.
* BadExportForYou: It is a HD show, but the Crunchyroll streams were limited to 480P.
* TheDanza: Shiraishi, voiced by Creator/MinoruShiraishi. Hell, he even gets to say his famous [[Literature/HaruhiSuzumiya Wasuremono]] line up to ''how he says it''.
* DevelopmentHell: From announcement to release took three years, including two years of complete silence and an unexplained change of animation studio:
** The "K-G.2" project was announced in October 2006.
** In January 2007 the studio (asread) and basic details were announced.
** A Pilot [=DVD=] was released in May 2007.
** ???
** In February 2009 the official title was finally announced along with news that it was now being animated by Satelight. Clearly there was also more than a little tweaking done to the basic story as well since it bore little resemblance to the Pilot and one of the main characters had a fairly radical redesign, both in appearance and personality.
** The first episode aired in October 2009.
* LateExportForYou: This show wouldn't be officially released on home video in North America until 7 years later in 2017.
* NoDubForYou: When the series was finally released on Blu-ray in North America, Creator/{{Funimation}} released it sub only despite the original series having a dub, likely due to ''Kiddy Grade'' generally being more of a niche show to begin with. Not helping matters is the fact that by the time Funimation released it, ''Kiddy [=GiRL=]-AND'' was a 7 year old sequel to a then 15 year old niche anime, and there wasn't much of a demand for it given the general reception to ''Kiddy [=GiRL=]-AND''.
* RoleReprise: All characters from the original series that have a speaking role here are voiced by their original voice actors.
* SequelGap: ''Anime/KiddyGrade'' premiered in 2002, ''Kiddy [=GiRL=]-AND'' was made in 2009, 8 years after the original
* WhatCouldHaveBeen: In the original [[https://www.youtube.com/watch?v=R9M3Bl9WuNc KG2 pilot]], it is implied that Q-Feuille would have been Eclaire's successor and thus the main character.
