“We pledge to uphold sportsmanship and fight to the death with honor!” 42-year-old salaryman Akihiko Ago wakes up to find his world completely transformed. It’s still modern-day Japan… except now, a deadly sport known as D-Sports—where slaughter is not only allowed but glorified—has taken the nation by storm. The rules are simple: Lose? You're killed. Break the rules? You're killed. Akihiko is still unaware that he’s about to be thrown into this insane competition. The first event? D-500 Meter Dash. Let the absurd death-match sports festival begin!
