It is common knowledge that nobles will do anything for power; lying, manipulation, and extortion are the usual tactics. However, one family is exempt from this generalization: House Grail, whose main tenets are truth and integrity. The youngest daughter, Constance Grail, is just as moral as the rest of her family, believing in always doing the right thing and helping those in need.
However, these ideals do not help her when her fiancé cheats on her with another woman. Framed by his lover in the hope of her downfall, Constance has no one to hear her pleas for justice. Everyone turns a blind eye, save for one—the spirit of the infamous Scarlett Castiel—who possesses Constance and turns the tables on her accuser. However, this aid does not come without a price.
Ten years ago, Scarlett was executed for the attempted murder of Princess Cecilia. But this was actually a setup; as blunt and harsh as Scarlett could be, she would never stoop so low as to use poison. She has no idea who orchestrated her incrimination, but Scarlett demands that Constance—as the only one who can see her—help her exact revenge on all those who wronged her!

Where it came from
The Holy Grail of Eris is a 2026 television series produced by Ashi Productions, based on the light novel series by Kujira Tokiwa. The project was initiated to adapt the popular 'villainess' subgenre of fantasy literature, focusing on a narrative of political intrigue and supernatural mystery. The production was designed to leverage Ashi Productions' signature animation style, emphasizing atmospheric lighting and detailed character portraits to distinguish the series from standard isekai fare.
The design and aesthetic direction aimed to evoke a sense of refined, gothic elegance, mirroring the series' focus on courtly drama and historical weight. Upon its release, the series received notable attention for its high-fidelity art style and its departure from the more comedic tropes of its contemporary genre peers. Critics generally praised the visual composition, which was intended to ground the magical elements of the narrative in a more somber, tactile reality.
