Really charming and heartfelt manga by an author that really really likes fish. Funa's love for all things aquatic and unique art style absolutely shine in this, and in my opinion this is the best way of experiencing the story overall; better paced than the game, with characters that feel much more alive and expressive than what RPG talk sprites can deliver. That said, it's hard to recommend Ounabara to Wadanohara to anyone who didn't grow up with the game. It doesn't really do anything particularly crazy or new, much like the game that preceded it; more than anything it feels like an excuse tobe shown the author's OCs, with a just competent enough plot to keep you going.

Also worth noting that the third volume covering the most memorable arc of the game was never officially translated into English, so if you're OCD like me about having all the volumes stacked nicely together it's going to bother you for the rest of your life.

TL;DR if you're a fan or nostalgic for the original or just like Funa's distinct art style, give this a peep! Preferably while under_the_sea.mp3 plays in the background.

EDIT: After replaying the game, I no longer think this manga is the best way of experiencing the story, as it glosses over a few plot points, characters, and skips some fun moments and scenes. The art remains excellent, but this manga is just a novelty for fans of DSP's stuff and shouldn't be recommended to your friends who aren't already into the game.
