The Nippon Marathon is an annual phenomenon that sweeps the nation of Japan. Every year, thousands of hopefuls apply for entry into the marathon but only 100 make it through the qualifying stage. Contestants race in groups of four and accrue points as they go. Being top of the leaderboard at the end of the gruelling saga is each contestant's dream.

This dream, however, has been claimed year after year by Handsome Hazuki: Ten-time Nippon Marathon Champion, beloved actor and vision of utter masculinity. He's shared the top bracket with Shiro Hideko, Felix and KG Park. Together they're known as the Fastest Four, they're totally BOSS.

But this year is special. It marks both the 100th Nippon Marathon, and the debut of our heroes J DARWIN, Elizabeth Nishibori, Zenbei "XEN BAE" and Snuguru Maestro.

Do they have what it takes to dethrone Hazuki and his pals? With your help, they just might!
