Nice. I've been reading it weekly from almost the start of it. It has some weird parts like the balls thing lol, but overall it's awesome.
Yeah, "schlong" and "golden nuts" fixation is a little weird, but I guess the author was too tired of the usual culprits such as souls, hearts, and to lesser extent eyes. Since most of the manga is a wild ride, I let it slide, like ok, they're looking for a part of Okarun powers, how exactly this works is a running gag, but whatever, the main idea is to get them back. I also like plots where the heroes of the story screw up and spend the rest of the story fixing their mistakes, because it almost always results in great character development. So yeah, there's no big epic goal like becoming a Pirate King, but fixing what you broke with your own hands due to ignorance is closer to reality. Dandadan is not only a manga about crazy world full of evil spirits and aliens, it's also a manga about growing up, developing relationships, owning to your mistakes, overcoming obstacles. It's both surreal and something everyone can relate to.
