This world is a prison. Everyone is chained. You and me too... Komori, a somewhat reclusive novelist currently undergoing mental treatment, meets Dan, a demon sentenced to hard labor for treason at "Cafe Prison," a cafe that attracts the mentally ill. AI prison guards, carnivorous plants, a fortune teller, a geeky girl, and an overprotective muscle-brained angel... The strange characters who gather around Komori and Dan... Centered around a cafe swirling with past grudges, love, and hate, this is the beginning of a story of rebirth, where a damaged heart and freedom are regained.
