"For just one day, I want to become human and dance with them at the bon festival dance." Ashiya and Zenko bring yokai Keshi to the Mononokean where they work together with Abeno to disguise her as a human so they can enjoy the Bon festival dance together. After granting Keshi's wish and sending her back to the Underworld, Abeno collapses from exhaustion and falls asleep. Abeno had just finished a job for the Executive, which he kept secret from Ashiya. Believing it's his own fault Abeno pushed himself beyond his limits, Ashiya feels responsible and worries for Abeno's wellbeing.

Yahiko came to the annual festival in high school after Zenko. Haruitsuki takes him out to a mountain to play hide and seek, because Yahiko plays pranks. And then, he gets a clue to Sakae from Yahiko.
