The Morose Mononokean Season 1 Episode 8

The Wait

Zenko arranges for Yahiko to help around the temple while he stays with her. Ashiya is relieved, but he soon runs into another yokai. The bird yokai Jomatsu is concerned for his heartbroken mistress Princess Anmo, who withdrew into an egg shell she made and hasn't come out for a long time. Jomatsu has been searching for the Mononokean so he can return to the Underworld with Princess Anmo still inside her egg.
