Record of Ragnarok III

Every thousand years, gods from different mythologies meet to decide whether humanity exists or should be destroyed. They get tired of human greed, and they all agree to wipe out humanity completely. But before they finalized their decision, Brunhilde, one of the 13 Valkyries, stepped in. She suggests the concept of Ragnarok, a series of one battle after another between 13 gods and 13 powerful humans in history. The gods first mock her idea, but later they accept the challenge. Now she has to gather the 13 strongest humans to fight against the gods to save humanity.
