This two-episode OVA returns to Kojou Akatsuki, the Fourth Progenitor vampire, and his sword-shaman observer Yukina Himeragi as the Kingdom of Aldegyr comes to Itogami City for peace talks. Princess La Folia Rihavein arrives with the delegation, and when unknown assailants strike the royal party at that evening's reception, a mysterious woman puts Kojou under a spell and the princess disappears. The original story brings back the first season's cast outside the main TV run.
