Beautiful and distorted sensual story of the devil and the girl. Yoshino, who wasn't drawn in the main story when she was 18 years old. The contract with the devil Belial "will pay one price and one wish will come true" will change when Yoshino reaches the age of 18. A kiss that entangles the tongue as a consideration. A record that depicts the time when it changed from parents to men and women from the perspective of Belial.
