Shuumatsu no Walküre III

The story keeps moving forward in the third season, where all the gods of Greek, Norse, and Hindu myths come together after a thousand years to make a big decision about human fate. All tired of human selfishness, they choose to wipe out humans. When they are about to finalize their decision, Brunhilde, one of the 13 Valkyries of Valhalla, interrupts to rescue mankind. She suggests the Ragnarök idea, where 13 mighty human warriors fight 13 gods in a solo battle. First, gods make fun of this concept, but she carefully uses their pride to accept this. Now, Brunhilde needs to pick the strongest humans across history and lead them to victory before their ultimate end.
