Dandadan, Vol. 17

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 has fallen into a cursed diorama, where she meets a guy named Zuma--the same Zuma who stole Okarun's family jewel! The inside of the diorama is laid out a bit like a game board, and it isn't long before Momo's forced to team up with Zuma to retrieve the family jewel after he drops it in enemy territory. Now the two must fight some frogs and a giant chef to get it back. Meanwhile, in the outside world, Okarun clashes with Zuma's friends over how best to rescue them!
