Dandadan, Vol. 18

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?!

The diorama board game that Momo and Zuma cleared to secure their release turns out to be a cursed wicker trunk imprisoning an evil yokai called the Fairy-Tale Card. The yokai possesses Zuma and draws 'Brella Boy's power to its fullest, turning him against Okarun and the others. Momo is seriously injured. Just as all seems lost, Rokuro appears.
