Don't sleep on this. This is REALLY unique to the point that I can't really make any sort of prediction on what will happen cuz the premise is just THAT fresh. What the hell do you even expect from this kind of premise?
From the chapters I've read so far, it doesn't disappoint. It feels so fun watching these guys just... catch fish. A subject I had no interest or any idea of.
Edit: It is SUCH A FUCKING SHAME that this lasted so short. I could tell that the author had SO MUCH MORE planned out, but it was forced to end on such a sudden note. If the side characters got some more character development like Haruna did, this would easily be one of the best manga I would've ever read. But sadly, that's not the case here.
