In Norse mythology, Ragnarok is a series of events, as well as a good battle, expected to guide to the death of a variety of many figures (including the Gods Norse deity, Thor, Týr, Freyr, Heimdal and Loki), natural disasters and therefore the submersion of the world in water.
Once these events, the world can resurface and fertile, the living and returning gods can meet and therefore the world will be repopulated by two human survivors. Ragnarok is a vital event in Norse mythology and has been the topic of scholarly discourse and theory within the history of Germanic studies.
The event is genuine primarily within the Poetic Edda, compiled within the thirteenth century from earlier ancient sources and therefore the Prose Edda, written within the thirteenth century by Snorri Sturluson. In the Prose Edda and during a single literary work in the Poetic Edda, the event is noted as Ragnarok or Ragnarokkr (Old Norse for “Fate of the Gods” and “Twilight of the Gods”, respectively), a usage popularized by 19th-century musician composer with the title of the last of his Der Ring des Nibelungen operas, Götterdämmerung (1876), that is “Twilight of the Gods” in German. So this manga is all about the gods.
When the god decides a convention to determine whether or not to let humanity live or die, and choose destroying humanity. However a lone mythical being puts forward a suggestion to let the gods and humanity fight one last battle as a final hope for humanity’s continued survival. Thirteen gods can fight against thirteen human champions in one-on-one battles to determine whether or not humanity lives or dies.
