* AllStarCast: Half of the cast are very well-known in the voice acting industry, such as Creator/KosukeToriumi, Creator/TomokazuSugita, Creator/JunFukuyama and Creator/HikaruMidorikawa, to name a few. ''True Blood'' would also include Creator/HiroshiKamiya into the mix.
* CashCowFranchise: Before ''VisualNovel/DramaticalMurder'' came along, ''Togainu no Chi'' had the strongest following of Nitro+[=CHiRAL=]'s first three works and had the highest amount of merchandise, and was the only one of the three to get an AnimatedAdaptation (albeit one that was poorly received).
* FanTranslation: Prior to the localization by JAST BLUE, ''Togainu no Chi'' had a complete fanmade English patch.
* PlayingAgainstType:
** Creator/HikaruMidorikawa, who usually play the {{Uke}} in BL works, plays [[{{Seme}} Shiki]].
** Creator/TomokazuSugita normally plays DeadpanSnarker characters; but in ''Togainu no Chi'', he plays [[DoggedNiceGuy Keisuke]].
* PornNames: With the exception of Creator/KazuyaIchijo and Creator/HikaruMidorikawa, the rest of the cast were credited using pseudonyms. Though they eventually stopped with this after the AnimatedAdaptation was released, with any future material that featured characters from ''Togainu no Chi'' crediting the voice actors by their actual names.
* PortOverdosed: So far, ''Togainu no Chi'' has been ported to the [=PS2=], PSP, and the [=iPhone=].
* WhatCouldHaveBeen: According to one of the artbooks, Gwen was supposed to have a romance route.
