Celestine Baudelaire

Celestine Baudelaire (often called "Celes") is a supporting character in How NOT to Summon a Demon Lord (Isekai Maou to Shoukan Shoujo no Dorei Majutsu).

She serves as the head of the Mage's Association in the city of Faltra, where she is responsible for maintaining the magical barrier that protects the city from demonic threats. She's one of the few people aware of certain secrets early on, such as aspects of Rem Galleu's background.

Celestine is depicted as a beautiful, mature woman with long blue hair (sometimes described with purple tones in adaptations) and a gentle, composed demeanor that carries a soft, almost child-like openness at times. She has a calm and reasonable personality, showing open-mindedness and trust once someone proves themselves (like Diablo after he defends the city). She initially views Diablo with suspicion due to the circumstances of his arrival and the slave collars on Rem and Shera.

She appears from early in the series (starting in episode 1 of the anime) and plays a supportive role in Faltra-related events. Voiced by Sayaka Senbongi (Japanese) and Marissa Lenti (English dub).
