Yuu, a plain and exhausted office worker stuck in a soul-crushing black company, dies and is reincarnated as a young girl with horns. To her surprise, she encounters Ajisai, a beautiful beast-woman, and ends up “sharing her soul” with her… through a deep, passionate kiss!

Even as her life force is being drained, Yuu feels a nervous thrill around the alluring Ajisai and a growing sense of fulfillment in being able to give herself to someone else. As for Ajisai, who initially saw Yuu as nothing more than a meal, she slowly begins to open her heart.
