Demons and humans have been enemies for a long time. Their castles are far apart, and relations are strained. However, there are both kind and cruel individuals on both sides. Satoru Gojo, the demon king, abducted the human princess, Anon, intending to use her as a hostage. However, she’s a troublemaker who repeatedly escapes her prison cell, only to return on her own. She possesses powerful magic but chooses not to use it against her captors. Over time, Satoru and the other demons grow attached to her. She explores the castle, decorates her cell with stolen items, and interacts playfully with the demons. Satoru, despite his position, finds himself captivated by her and acts more like a devoted companion than a captor. He often finds her in unexpected places, and while he playfully scolds her, he never truly punishes her severely. He wonders about her actions and enjoys her company.
