Overall, Higanjima is a very weird case for me. The manga seems like complete garbage, with an inconsistent story, characters and their habits that are incredibly stupid and nonsensical, a repetitive plot (I'm amazed it has over 33 volumes with this plot), and overall questionable writing quality. This would be true if you take this manga seriously, but if not, it's an incredibly charming series. You'll enjoy the author's bizarre fetishes, such as peeing fetish, the various and creepy creature designs, and the memorable characters who, despite being stupid and annoying as fuck, I think the author did a good job of giving them appropriatescreen time even tho they didn't have much character development (except for the protaginist). And then there's the overpower final boss, Miyabi, who I think is quite charming and well-written compared to antogonists in other series. He never dies, simply because... and the author probably doesn't want the reader to know why he's immortal, because he might think that letting him live forever and repeatedly fuck with the protag group is funnier.

As for the story, it's so absurd it's comical, and that's the perfect charm of this series. If you like watching funny train wrecks, you've come to the right place. The storytelling is no different from a gag manga, no matter how much the author tries to make it serious. There's so much of this kind of thing that I don't know how to describe it all. You should probably just read it yourself.

The art is okay and fits the series' tone well. There's not much to say here.

Whether Higanjima is a good series or not, I think it's definitely bad enough to be good.

I'll give it a 7.5/10 because I like its weirdness, and it's amazing that I know the series has multiple sequels and Miyabi is still alive until now.......
