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 has fallen into a cursed diorama laid out like a giant game board, where she meets Zuma, the same alien who stole Okarun's family jewel. They team up to retrieve it after Zuma drops it in enemy territory, fighting 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.
