A very unexpected addition to the anime tradition where adolescence is represented through literal body transformation and guided by innermost urges and desires of the flesh, but this time turning into... a very actual critique of the politics of hate via biblical apocalypse?
Fear & desire turn into hate for the outgroup, and Anime, as a genre, keeps surprising me by being one of the artforms more directly engaged with the world's climate during the resurgence of the extreme right.
That being said, about the series: great animation, and it takes such a dark turn during the end stretch that it gets downright nightmarish, including a couple of the more disturbing deaths in the genre. Very horny & profoundly hopeless. Kind of wish I could've spent more time at the end of the world, though.
