Humanity tries to develop a revolutionary new energy source, accidentally tears open a hole to new dimensions and spreads an "Evolutionary Field" across the planet. With the exception of humanity, both animals and AI rapidly evolve together, eventually merging into a new being, dubbed BRAI, that rips Man a new one. Walling themselves into heavily fortified megacities, the remnants of humanity fight back with shitty ineffectual CGI mechs as they desperately attempt to stave off the inevitable.
Feels like the unholy fusion of God Eater and Kabaneri then slammed into the mecha genre, but with not nearly the budget of either. It's still pretty interesting though, and it's created by the dude behind Macross, Escaflowne, Aquarion, and other favorites, so it's bound to be at least average.
