A nerd must fight powerful spirits and aliens all vying for the secret power of his family jewel, so who better to fight alongside him than his high school crush and a spirit granny?!

Momo Ayase and Okarun are on opposite sides of the paranormal spectrum regarding what they’ll believe in and what they won’t. Their quest to prove each other wrong leads them down a path of secret crushes and paranormal battles they’ll have to participate in to believe!

Momo and the others have succeeded in escaping the cursed trunk and defeating the Fairy-Tale Card, but because Momo ate the sweets inside the trunk, she has shrunk to the size of a fairy! While her grandma looks for a way to return her to her previous size, Momo heads back to school in her new, tinier form. It’s there that she hits on the idea to research fairies in the library, and once there, she spots…a pygmy?!
