This year's 14th issue of Shogakukan 's Big Comic Spirits magazine is announcing on Monday that an anime adaptation of Junji Ito 's Gyo horror manga has been green-lit.

In the story, strange, legged fish appear in Okinawa in southern Japan, and the creatures portend a horrific change for the animal life in the area. Tadashi and and his girlfriend Kaori find themselves trapped on an island, facing a fate worse than death.

Viz Media published the two volumes of the manga in North America. Ito also created the Tomie and Uzumaki manga, and both inspired live-action horror films.
