Pleinair-San (プレネールさん) is a recurring mascot-like character in the Makai Senki Disgaea series. She is a cheerful, energetic girl with an unmistakable blue outfit and a camera, often appearing as a self-referential guide or observer of the Disgaea world. Rather than serving as a major combat-focused lead, she functions as a familiar cameo character and promotional figure, helping give the series its playful, meta humor. Her role is mainly to add charm, continuity, and a recognizable face across Disgaea-related media.
