Lolita°C is a fictional personality that appears in the manga, novel, and live-action television series MPD Psycho, originally written by Eiji Ōtsuka and illustrated by Shōu Tajima. She is introduced as a girl who believes that the world is composed of literature and that everything can be understood through stories. Over the course of the narrative, she dies six times and becomes a digital existence, a ghost-like entity that exists within data networks. She is described as an eternal girl and is closely tied to the fictional counterculture musician Lucy Monostone, performing Lucy's songs and acting as a vessel for her legacy. Lolita°C composes her own song titles and lyrics, and her music is used as a means of psychologically influencing people, a trait that aligns with the series' themes of identity manipulation and conspiracy. Her personality is literary, ethereal, and detached, reflecting her nature as a digitized consciousness that transcends physical death. She interacts with other characters through telephone lines, the internet, and recorded media, and her existence serves as a bridge between the real world and the programmed personalities created by the Gakuso organization. Her role deepens as the series explores the connections between Lucy Monostone, the barcode phenomenon, and the true nature of the multiple personalities. Lolita°C's development traces her transformation from a mortal girl into a persistent digital presence, and she remains a recurring symbol of the intersection between art, technology, and psychological control.
