Aoi "Blu" Kudo-- one of the only humans to ever compete against numerous beastmen (anthromorphs) in a fictional racing association called "The HEADRUSH World Series". Alongside him is the current 8 time champion herself -- Tethys Spritzamas. Gone through a ton of bad stuff, she's hardly has sympathy for anyone but herself.

Blu has the '01 Skyline z-tune, and Tethys has her '26 Corvette ZR1X "Pikes Peak".
