Confusing is the 5th episode of the anime.
Ichiko wants to take Yumemi to the amusement park to try to take her mind off of the floating islands only she can see. When Yumemi, Ichiko, and Suzume are helping out at Takeshi's shrine, Yumemi finds a large rock near the shrine which reacts to her touch, enabling her to get closer to Munto for an instant, but is then repelled. Yumemi continues to have visions of Munto's past, and Ichiko worries about her well being. The day they go to the amusement park, the day starts off well but later when they are eating lunch Yumemi starts acting strange and suddenly something falls from the sky causing a huge explosion.
