Ep. 4: Keima confronts Tsukiyo and Vulcanus while Nora reveals the infiltration plot to Haqua.

Keima visits the library to read Shiori’s story under surveillance. Nora confronts Haqua about Kanon. Keima encounters Luna, who is revealed to be Vulcanus, warning him away from Tsukiyo. He approaches Tsukiyo to hide Vulcanus, unaware she controls objects. Both Tsukiyo and Vulcanus are angry about his infidelity, but he reminds Tsukiyo of their promise. She kisses him due to pity for his injury, causing her to grow wings. Nora informs Haqua that Vintage has infiltrated spirit hunters and the search for goddesses is a trap. Diana and Vulcanus combine powers to remove a cursed dagger, while Apollo liquefies Kanon’s body for preservation. Haqua confesses feelings for Keima but is interrupted by Diana. Diana is jealous that Vulcanus regained wings while she has not, despite Tenri loving Keima longer. Keima calms her, leading Diana to realize her hatred blocks her power restoration. She attempts acceptance, and Diana’s wings appear as Tenri leaves.
