About The Holy Grail of Eris

Meet The Holy Grail of Eris (エリスの聖杯), a drama, fantasy and mystery anime by Ashi Productions (2026). Here is the premise in a nutshell. In short: It is common knowledge that nobles will do anything for ability; 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.

Further in, 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.

With drama at the core, character writing and emotional payoff matter more than spectacle. Scarlet Castiel (Sayumi Suzushiro) and Constance Grail (Kana Ichinose) are two of the characters you will meet early. If you count yourself among viewers who prefer story and feelings over flashy action, put it on your list. At 12 episodes in total, it is easy to plan a viewing schedule.

Production & Appeal

Animation is handled by Ashi Productions, so the studio's house style defines how The Holy Grail of Eris looks and moves on screen. Because it leans on drama, character writing and emotional payoff matter more than spectacle. With a 6.9/10 score, it is more of a niche pick than a universal crowd-pleaser. On the casting side, Sayumi Suzushiro voicing Scarlet Castiel gives the lead role a recognizable voice. Released in 2026, it competed with that season's other new series for attention.
