Kitaro and the others celebrate the fishing festival with everyone from Sakaiminato. Then, Mana hears a strange voice calling her and disappears. At the same time, the door to the hidden village of Yumigahama opens. The voice calling to Mana leads her across a bridge and through that door. When she regains her senses, Mana is in a place overgrown with beautiful flowers. There, she meets children dressed in Japanese clothes. The boy who leads them, Ichinoshin, tells her she can't return from that place. He also tells her that they are from the second year of Bunsei, which means they're children from the Edo era. Will Kitaro and the others be able to find Mana? And what about the children...?!
