The first promotional video for Dark Moon: The Blood Altar has been released, offering a glimpse into the supernatural school drama. The trailer showcases protagonist Sooha, who lives in fear of her own hidden superhuman abilities, which are often mistaken for vampirism. The series follows her enrollment in Decelis Academy, a night school ostensibly for supernatural beings like vampires and werewolves, where she attempts to conceal her true nature.

Produced by TROYCA, known for their work on series like Re:ZERO -Starting Life in Another World- and Sword Art Online Alternative Gun Gale Online, Dark Moon: The Blood Altar is an adaptation of the manga of the same name. The PV hints at the central conflict: Sooha's struggle for normalcy amidst a student body of monsters, and the potential dangers of her secret being exposed. The trailer also introduces Heli, a fellow student who offers friendship despite knowing her secret, suggesting a complex dynamic within the academy.

The series promises a blend of fantasy, school life, and potentially a male harem, as Sooha navigates her new environment. With Aniplex and Crunchyroll among the producers, the anime is poised for a Winter 2026 debut, adapting the ongoing manga and exploring themes of hidden identity and acceptance within a world of supernatural beings.
