This will be the summer film for the 38th Super Sentai team Kemonogun Sentai Armagejer. This happens before the appearance of ArmageGreen.
While the Armagejers were battling Akuza in a small Kyoto town, they unearth a mysterious mirror that takes anyone to a dimension where everyone and everything is opposite compared to the real world. When the Armagejers were sucked in, they find this place "weird." And so, the Akuza plans to take advantage to this situation, and plan another human/animal war. Will the Armagejers learn to trust the reverse-Akuza and escape to the real world in time?
