Humanity's third in Ragnarok.
Kojiro Sasaki's a famous swordsman from Japan, known as "History's Greatest Loser".

The story begins when the gods call a convention to decide whether to let humanity live or die, and settle on destroying humanity. But a lone valkyrie puts forward a suggestion to let the gods and humanity fight one last battle, as a last hope for humanity's continued survival. 13 gods will fight against 13 human champions in one-on-one battles to decide whether humanity lives or dies.


7 million years of human civilization is coming to an end…
 
Every thousand years, all the gods of the world gather in heaven to attend the Conference of Mankind Survival. The gods agree to end to mankind due to their foolish acts, but before the final verdict is made, Brunhild, the eldest of the 13 valkyrie sisters, makes an objection.
 
“To spice things up, why don’t you test the humans?”
 
She proposes that the all-powerful gods face off in one-on-one battles against the strongest champions from human history — during a final struggle known as “Ragnarok.” The first team to win 7 out of 13 battles will be declared the winner, but it seems almost impossible for humans to win against the gods. 
 
Although the gods sneer at her declaration, Brunhild provokes them further:
 
“Are you chickening out?”
 
Her words hit the gods’ nerves, and, enraged, they accept her proposal. Now, Brunhild and her sisters must choose humanity’s 13 champions in a desperate battle for survival. Will humans surpass gods and prevent humanity’s ultimate end? The eschatological battles between heaven and earth finally begins!

In a shocking turn of events, humanity has won its first battle in the Ragnarök tournament—a series of 13 fights that will decide the fate of mankind. Zeus, the head of gods, sends the demigod Heracles for the next round to avenge the humiliated Greek pantheon. To face this hero loved by gods and humans alike, the Valkyrie Brunhilde decides to use Heracles' complete moral opposite: the infamous serial killer Jack the Ripper—leaving human beings unsure who they should support.
 
Meanwhile, tensions begin to rise between various divine pantheons, and rumors of a traitor jeopardize the unity of those who want to annihilate humanity. As the line between friend and foe becomes blurred, Brunhilde will do everything she can to make her machinations successful.
