Dandadan, Vol. 15

Now that the alien invasion has been thwarted, Okarun and the others start a research club with the goal of finding his missing family jewel. As they get the club running, they can't shake their suspicion of their assigned advisor, Mr. Sanjo, whom none of them can quite remember meeting before. Soon after, Okarun's class rep reveals that ever since she picked up a strange gold ball, he's started to look like a handsome vampire.
