Record of Ragnarok

Oc's from the anime/manga series Record of Ragnarok;

Ragnarok (神ＶＳ人類最終闘争ラグナロク, Ragunaroku) is Mankind's final struggle against the Gods. Explained in the Valhalla Constitution, article No. 62, paragraph 15 of the "super special clause," it is a series of one-on-one showdowns between the Gods and Mankind.

The rules are quite simple. Each side picks thirteen fighters, who will fight one-on-one fights to the death and the winning side is the one that gets seven victories first.

If the Gods win the Ragnarok, Humanity's fate is sealed and it will be extinguished. However, if the Humans win, they will gain the right to live for another 1000 years.
