Ashiya's friends Saga and Fushimi invite Ashiya and Abeno on the photography club's overnight trip. Since the incident with the Executive, Ashiya has been able to detect yokai at a distance. However, he still hasn't mastered that skill, so Abeno uses the overnight trip to develop Ashiya's detection ability. Yahiko is invited along to help, but a prank he pulls on Ashiya draws out another one of his latent powers!

"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.
