Shūmatsu no Valkyrie also known as Record of Ragnarok it's available on Netflix. My husband recommended to me (made me watch lol) and I liked it a lot!
The plot is about Gods wanting to eliminate humankind, so there's is an arrangement. Gods and humans most select their warriors to go in 1v1 battle to decide the humankind future.
So you will see greek gods and historical famous humans fighting in different styles. To make it even the valkyries will support the human contender (a Valkyrie can turn into a weapon with the ability to attack the gods).
If you like action I suggest this one
