In giant colosseum we can see many beings sitting and watching. On one side were Gods, demons and other supernatural beings belonging to all kind of mythologies who wanted to destroy humanity and on the other side were all humans who existed from the beginning of time until now.
This was Ragnarok, event for which was said that it is an destruction of Asgard where Norse Gods fight their biggest enemies, but instead it was Gods against Humanity. Thirteen Gods against Thirteen Humans. That was decided when Brunhilde and Geir, oldest and youngest valkyries, interrupted meeting of Gods and proposed that. Gods at first wanted to reject it, but Brunhilde tricked them into it as she brought their pride in the matter saying they want to destroy humanity without coming into contact with them. And so that is how it began.
In the first battle it was a strongest chinese hero from time of Three Kingdoms, Lu Bu against strongest nordic god Thor, Berserker of Thunder. It was a magnificent battle where during the fight two acknowledged each other as a rival.
During the fight, it was revealed that humans and valkyries worked together by performing pact called Volund. It is a process where Valkyrie becomes a divine weapon for human as weapons made by mortal hands weren't strong enough to fight against weapons made by gods.
Back to the fight, when Lu Bu destroy one of Thor's gloves Mjolnir fell to the ground and to the shock of all, except of few, veins appeared and thus real fight started. In the end it was Thor who won with deciding move being GEIRROD THOR'S HAMMER.
After Lu Bu died, army which followed him during his time attacked Thor showing their loyalty towards their lord and died.
In the second fight a representative of Humanity was someone who existed from the beginning of time, human who committed original sin, father of humanity, ADAM!
And his opponent was King of Greek Gods, Father of Gods, G.F.O.C, ZEUS!
In the beginning of fight it was Zeus who started and yet Adam dodged his attacks easily and copied them all and used them on Zeus. Brunhilde then revealed that as Adam was created in image of gods, he could copy their attacks using the only ability of his called Eyes of the Lord.
It looked like Adam was going to win that fight, but then Zeus revealed his ultimate technique and tides turned to the favor of Gods. During the fight, Adam went blind from overuse of his eyes and yet proved he could still fight. In the end Adam remained standing with Zeus down in his normal form.
It was thought that Adam won, but after few seconds Heimdall revealed Adam died. All humanity cried after their father and Eve, Adam's wife, broke down seeing her husband die.
In third fight representative of Gods was Poseidon, Tyrant of the Seas, who hated all gods and humans, and saw them as trash. And his opponent was Strongest Loser of Humanity, Sasaki Kojiro.
It was a fight where tides in second would turn favor towards Gods and other second in favor of Humanity. When Poseidon broke Sasaki's monohoshizao, Sasaki took parts of his blade and again to the shock of all used Re-Volund and in his blades appeared two blades. He then used all techniques of all swordmasters he fought against in his time using them as they were his and in the end killed Poseidon with deciding move being SWALLOW TIGER COMBO, THOUSAND BLADES.
In third fight, it was a battle between a man who took lives of five prostitutes, who in the blink of an eye cast the entirety of London into chaos, the darkest of evils. He was known as HUMANITY'S MOST INFAMOUS SERIAL KILLER!! JACK THE RIPPER!
And his opponent was a gallant demigod who killed Nemean lion and forced Cerberus into submission and after completing twelve labors ascended to the steps of Olympus. THE ENVOY OF JUSTICE! HERACLES!
