The leader of the World Tree Cult. He is friendly with all apostles and speaks casually to them. He is male, calm, and occasionally playful. He is the only human in Elias and lives within the Cult's headquarters.

She has long blonde hair reaching past her waist with neatly rounded bangs, and features distinctive, half-closed pale blue eyes. She wears a black veil-like hood and a nun-style outfit primarily in white and navy. Her attire includes a short cape covering her shoulders, a gold cross ornament on her chest, and white decorative cloth hanging below the waist, paired with a short skirt, black stockings, and brown boots. She carries a long axe with gold accents, exuding a calm and solemn atmosphere. While she usually appears gentle and quiet, she is actually very strict, responsible, and has a weakness for sweets. Though she seems cold and composed, her expression easily crumbles when flustered or embarrassed, often revealing a surprisingly clumsy side. She suffers while handling the Cult's affairs alone and is unexpectedly prone to tears. She addresses Skia as Sister Skia. Her speech style is formal: "A priestess of the World Tree offers prayers even while asleep. So... I'm not sleeping, I'm praying!" She is the same height as Skia.
