Description[edit | edit source]
Sixth grade elementary school students Kazuki, Taichi, and Sunny have a "wish" they really want to make it come true. The boys pray earnestly with their hands at the shrine. Then, suddenly, the wish-granting "Ghost Book" resonates with them and gives them a test. Guided by the magic of the Ghost Book, the boys and their homeroom teacher, Ms. Yohko, wander into a different world where ghosts live. The five try to escape from the world through trial and error. It seems that by catching the ghosts and completing the Ghost Book, their wishes will come true and they will be able to escape from this world. Thus, the five work together to challenge the scary ghosts. What are the boys' wish that they really want to make it come true?
