Once every millennium, the gods assemble to decide if humanity is worthy of its continued existence or if it should be destroyed! When the verdict is destruction, the final battle between the gods and mortal heroes will decide the survival or extinction of the human race--a battle known as Ragnarok!

Round 4 of Ragnarok has ended in a shocking win for humanity: Jack the Ripper stands victorious over the mighty Heracles. With the score now tied, the gods are absolutely determined not to let humanity get ahead. Raring to go since the start, Shiva, the Destroyer, finally gets his chance to enter the Valhalla arena. Brunhilde also doesn't want to give up the opportunity to take the lead and calls upon the unbridled strength of the greatest (and horniest) sumo wrestler in history, Raiden Tameemon!
