* RelationshipVoiceActor: Creator/AmandaWinnLee (Rally), Kimberly Yates (May), and Creator/TiffanyGrant (Becky) were ADV's most common female PowerTrio in the early nineties, showing up in ''Anime/BurnUp'' and ''Anime/DevilHunterYohko''.
* UnintentionalPeriodPiece: The series clearly happens in TheNineties, not only cause the fashions and hairstyles... but also because the animation recreated Chicago with incredible, accuracy, to the point many Chicago fans of the series can identify the specific time-period the anime was made by certain key features, most notably the construction scaffolding that surrounded the Field Museum of Natural History during that building's renovation.
* WordOfGay: According to Sonoda, Rally is a celibate lesbian. Kinda got [[http://gunsmithcats.livejournal.com/14606.html confirmed]], too.
