Myriad lives in a world of Personas. While some people are born with Personas, Myriad isn't...but what's this? She has powers suddenly? She finds herself living in a city she has never been before and being told that she is different than the average Persona wielder. After losing her mother, her closest relative, things change for the poor girl. Follow Myriad through her life of trauma, excitement, depression, and finding herself a new family. Of wonder. Of strangeness. Of music.

After an apocalypse in the unspecified "City X", outskirts of the city have become contaminated. People kill and steal to get their way. Kiri is different, though. She is living in a position where she decided to be innovative with her surroundings. Though the rain may be acidic, Kiri finds ways to make her life meaningful. Little does she know how much innovation, particularly with water, will help her.
