* {{Abandonware}}: The ultimate fate of the series after Nyu Media's closure in 2022 and Upgrade abandoning the series in 2023.
* ActorAllusion: Lugh Ciel's theme is called White Beelzebub and one of her attacks is named Despell Counter Excelion, in addition to attacks with "star" in the name. All of these point to the Franchise/LyricalNanoha franchise, specifically the title character Nanoha Takamachi, who is nicknamed the "White Devil", has attack spells called Excelion Buster and Starlight Breaker (not to mention the prominent start in her franchise's logo), and is also voiced by Creator/YukariTamura.
* KeepCirculatingTheTapes: Months after the game shifted publishing rights from Nyu Media to Upgrade, the latter went on to delist the series and their respective digital soundtracks at the start of 2023 since they could not give the rights back to FLAT and Tennen-Sozai when both doujin circles went under many years ago. Even before the Steam delisting, the series was slowly being delisted from other online distributors such as Gamersgate, DESURA, and even Nyu Media's own website. The only way these can be played currently is through hunting down a download of the games and their soundtracks elsewhere. On the flipside, the English versions of these games are also DRM-agnostic, even with the Steam version.
* ChannelHop: The Western publishing rights for the trilogy were transferred from Nyu Media to Upgrade with the former's closure in the Summer of 2022. The new ownership didn't last very long since Upgrade would later delist the entire series due to not being able to give the rights back to the original developers.
