At the end of Gamera 3:Revenge of iris we are given a HUGE plothole. All we know is a flock of Gyaos are heading towards Japan. In the Gamera 2016 - 2017 reboot trailer. We see a flock of Gyaos attacking a city. Is it possible that Gamera 2016 - 2017 is a direct sequel to Gamera 3? And could the new kaiju be related to it?
