Record of Ragnarok

Record of Ragnarok begins when the gods gather for their thousand-year Conference of Mankind Survival and decide that humanity should be destroyed. Brunhild, eldest of the thirteen Valkyrie sisters, challenges that verdict by proposing Ragnarok: thirteen one-on-one battles between gods and the strongest champions in human history. The first side to win seven matches determines humanity's fate, leaving Brunhild and her sisters to assemble thirteen fighters capable of defying the gods.
