Dandadan vol 23

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 board a plane bound for Izumo to deal with the effects of the cursed trunk. But the Kito clan, who escaped them before, take this moment to exact their revenge. Recently blinded Zuma and battered Seiko are struggling to defend themselves when, out of nowhere, frozen sharks begin piercing the plane?! Out of options, the enemies join forces to take on this new threat!
