The devil and the girl's story is one of distorted sensuality and beauty. Yoshino, who wasn't featured in the main plot when she was eighteen, is presented with a life-changing opportunity to make one wish come true for a price upon making a contract with Belial, the devil. A kiss, rife with consideration, entangles their tongues as Yoshino turns 18. Belial's perspective depicts the transition from parents to man and woman in a recorded tale.
