Gyo (Tokyo Fish Attack!)

The day the fish fought back!


A horrible rotting stench has accompanied Kaori’s trip with her friends for graduation. The source? A fish on mechanical legs. But that fish is a part of a larger issue, as soon enough a nation wide invasion of these creatures is upon them and they’re carrying something far worse than a foul odor.


With Tokyo under siege by these creatures, Kaori cuts her graduation trip short in order to rescue Tadashi, her boyfriend, before he too becomes a victim. But it becomes a daunting task when the city is barely recognisable and there are fish around every corner threatening her own safety.


A biological experiment gone wrong or the simple natural progress of evolution, Kaori might find out a truth she may not want to know in her quest to rescue Tadashi from this pandemic.
