Set in a human-like civilization, Lucas City, a woman by the name of Cherub is evicted from her apartment. She claims to be a higher being (which is [surprisingly] a cherub), yet her landlady refuses to believe her. Cherub travels to the local bank, to withdraw earnest money for her next residency. While she's there, however, a robbery takes place, which the events of turn supernatural. Afterwards, things begin to unfold: truths are revealed, enemies are determined, and alliances are formed.
