A great racer who is known and revered as “The Legend” (伝説様, "Densetsu-sama"). He went missing 100 years ago, leaving behind a number of records that nobody's been able to beat. A huge black star is carved on its back, as if to show off to those who challenge him. 
~!He's implied to have ties to Tomoe, possibly being her previous partner before Shiro.!~

On Tellus, a half-explored planet inhabited by immigrant pioneers and plagued by terraforming machine-induced earthquakes known as the "Stampedes", a promising young racer named Shiro suffers life-threatening injuries while chasing after the legendary "Loser King" alongside his lifelong rival, Goodspeed. On his deathbed, he is visited by a mysterious woman calling herself Tomoe, who gives him a second chance in life in exchange for participating in The Planet Re-Development Race - an annual event where daredevil mavericks from all across the globe gather not just in pursuit of an enormous amount of prize money, but to explore what lies in the unexplored parts of the planet.
