With Chastille's birthday quickly approaching, Barbatos is at his wits' end and goes to his friend for advice. However, at the exact moment, the bewitching Archdemon Eligor appears to recruit him. Shortly thereafter, Chastille witnesses Barbatos spending time with a gorgeous woman and decides to secretly tail them. Tremendously misunderstanding what she sees, she can no longer suppress her own feelings.

"That man is mine! Get your hands off him!"

It's finally time for Chastille and Barbatos to take center stage in this volume of Elf Bride!
