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!

The diorama board game that Momo and Zuma have cleared to secure their release has turned out to be a cursed wicker trunk imprisoning an evil yokai called the Fairy-Tale Card. The yokai quickly possesses Zuma and draws ’Brella Boy’s full power, then uses him to attack Okarun and the others, seriously injuring Momo. Just as all seems lost, Rokuro appears on the scene…with the police?!
