Sylvie

Sylvie is a supporting character in How NOT to Summon a Demon Lord (also known as Isekai Maou to Shoukan Shoujo no Dorei Majutsu).

She serves as the Guildmaster of the Adventurer's Guild in Faltra City, handling quests, commissions, and adventurer support.

As a Grasswalker (a rabbit-like demi-human race), she has a petite, youthful appearance with rabbit ears and a tail, short pink hair, and typically wears a revealing, thin outfit with ornaments that exposes her midriff.

Despite her cute and seemingly young look, her actual age is unknown (and she's implied to be much older/more experienced than she appears), with hints in the story that she was involved in major events like being one of the heroes who fought against a Demon Lord decades ago.

She's cheerful, helpful to the protagonists (especially Diablo's group), and has a playful side—sometimes meddling in romantic matters by encouraging pairings or setting up situations to make things more "energetic."
