We get some, uh, character development with Destiny, we get introduced to Justice (and actual character development), and we have a brief encounter with lady-bird.
It was a bit hard to watch the end with all the foreshadowing that Natsuko was going to mess things up.
Hmm, I can’t think of an anime that matches the trailer. That is to say, an anime that is an action-horror demon-world adventure with modern military weapons.
Hole in the ground with horror monsters makes me think of Made in Abyss.
There’s a gluttony of anime with monsters in dungeons, like DanMachi, Arifureta, and Solo Leveling.
There’s Chained Soldier, which technically takes place in a hell-ish place with monsters that is connected to regular earth. And there’s some military element to it.
There’s a gate to another world and modern military in Gate: Thus the JSDF Fought There!, but no monsters that I recall.
Just throwing some other out there: Hellsing Ultimate, Seraph of the End, WorldEnd, Dimension W, .
When I hear arctic demon, I can’t help but think about The Thing, which isn’t anime.
