Record of Ragnarok 25 (Japanese Edition) by Shinya Umemura

In the ultimate showdown between gods and humanity, the fate of mankind hangs by a thread! The gods have decided to wipe out humans after millennia of disappointment, but the Valkyries step in with a desperate plan: the Ragnarok--a brutal 13-vs-13 tournament where legendary human warriors (like Adam, Lu Bu, and Jack the Ripper) battle the mightiest gods (Zeus, Thor, Poseidon, Buddha, and more) in one-on-one deathmatches. Epic fights, insane powers, and shocking twists decide if humanity gets another 1,000 years to live!
