Capella Emerada Lugunica

Capella Emerada Lugunica is a Sin Archbishop of the Witch Cult in Re:Zero − Starting Life in Another World, representing the sin of Lust. She is also known as "Mother" (or "Mama") among her followers and controls a network of "children" (including assassins like Elsa and Meili in earlier arcs).

Her true appearance and even gender are unknown due to her Authority of Lust, which grants her the power to freely transform and reshape the bodies of herself and others (turning people into animals, monsters, different humans, or even healing/regenerating from severe damage). She most commonly appears as a petite teenage girl with short golden hair, crimson red eyes, and a revealing outfit.

Capella has an extremely narcissistic, sadistic, and twisted personality — she believes the entire world exists solely to love and worship her alone, viewing others as worthless "meat bags" unless they adore her. She's one of the major antagonists, particularly prominent in Arc 5 (adapted in Season 3 of the anime).
