Gyo tells the story of two teenagers Tadashi and his girlfriend Kaori as they take a holiday in Okinawa. Kaori is a girl with an extremely sensitive nose, and after a row with Tadashi about cleaning his teeth, Kaori is attacked by a fish… on legs.. It would appear, at first, that the two had discovered a new species of fish, that is until the island becomes overrun with legged sea creatures. All the creatures from the sea are on mechanical legs! – Asian Movie Pulse
That little synopsis does not do this anime adaptation of the Junji Ito survival horror manga any real justice. Sure the creatures of the sea (from the tiniest guppy to the biggest shark) are all roaming the streets of Okinawa on mechanical legs, propelled by their own gastric eruptions (farts?!) with one mission: to kill people!!!! But there is more twisted nonsense going on than just the war against the mechanized fish and it really needs to be seen to be fully appreciated. I was a tad bit unsure when I heard this was getting the anime treatment but the extended trailer eases any of my concerns (even though I am a bit bummed that I didn’t hear a Gashunk anywhere in that trailer vid). This may be the trippiest thing to come out of Japan since Chocoballs.
