Hideo Kawamura, an ordinary man with no job, ventured to Tokyo in search of employment. Despite applying to 34 different companies, he failed to even secure an interview. This left him feeling rejected and eventually led to him becoming a recluse, with his parents even cutting off financial support. Eventually, when he had no money left and had given up all hope, he stumbled upon a computer on the street, unwittingly infecting it with the Will.CO21 virus. This computer provided Hideo with a way to enter the Holy Devil Cup martial arts tournament, where the winner could gain ultimate power over the world. Hideo now finds himself among 3,024 participants, including martial artists, soldiers, vampires, and Majin. How will he navigate this twisted competition to come out on top?
