SHIBUYA GOLDFISH IN A NUTSHELL: This series is High School of the Dead but with flying goldfish instead of zombies (and a little less fanservice).
I'm three volumes in, and this is a great "turn your brain off and let the bizarre story wash over you" kind of read. Easy to follow, not a lot of plot, just "survive the giant goldfish who now fly through the air and hunger for human flesh." That's it; that's the manga! Nothing more, nothing less.
Does this series have depth? Nah!
Is it funny? Sometimes!
Is it fanservicey? Also sometimes!
Is that art all right? Yeah, mostly!
Will zombie-story fans like this? Yeah, probably!
Is there action? Yeah, and some of it is even good!
Does it make sense? Nah, not really, but I don't really want it to, so that's OK!
If you wanna read a story about goldfish eating people (complete with a body horror and gore), read this! If you don't, then don't! The story is exactly what it says on the tin. You can and should judge this book by its cover. And in this case, that's perfectly all right.
