Episode Description:
Keima arrives at the library whereupon Shiori allows him to read her story while being watched. Meanwhile, Nora discovers Kanon and demands an explanation from Haqua. In the library Keima discovers that Luna, Tsukiyo's doll, is Vulcanus who warns Keima never to approach Tsukiyo again. Attempting to stop Vulcanus from being discovered, he approaches Tsukiyo not realizing she is in fact truly Vulcanus controlling objects. With both Vulcanus and Tsukiyo mad at Keima for cheating on her, he makes Tsukiyo remember the promise he made to her. Succumbing to her pity for his injury, Tsukiyo kisses Keima whereupon she grows wings. Nora explains to Haqua that Vintage have infiltrated the spirit hunters and the search order for the goddesses is a plot to capture them. Reunited, Diana and Vulcanus combine their powers to remove the cursed dagger but Apollo turns Kanon's body into a liquid state as a preservation measure. After making a deal with Nora to help them, Haqua expresses her feelings for Keima only to be interrupted by Diana. Diana is angry that Vulcanus manage to regain her wings while she hasn't despite Tenri having loved Keima longer. After Keima calms her, Diana realizes her hatred for Keima is preventing the restoration of her powers and tries to accept him. As Tenri heads home, Diana's wings appear.
