Eris Seifort

Eris Seifort is a key supporting character in the Berserk of Gluttony anime adaptation. She is the bearer of the Mortal Sin Skill known as Lust (a powerful ability that allows her to charm or influence others, including people of any gender or even monsters on a large scale).

She is portrayed as the Queen of the royal capital Seifort (the central kingdom where much of the story unfolds). Eris first appears prominently later in the series (around Episode 9), where she encounters the protagonist Fate Graphite after he unlocks his Gluttony skill. She has knowledge of the Deadly Sins skills, has connections to past events and characters (including Myne), and follows or monitors Fate due to his abilities.

In the anime, she's depicted as a mysterious, elegant, and somewhat enigmatic woman with blue hair, who plays a significant role in revealing deeper lore about the world, the "Hate" force tied to suffering and monster creation, and the broader implications of the Sin skills. Her motivations tie into protecting or shaping the kingdom's future, sometimes through morally complex decisions.

(She's voiced by Hitomi Sekine in Japanese.)
