A young boy named Rudo lives in the slums of a wealthy society among the "tribesfolk" population who descended from criminals exiled by society. Rudo detests the upper class' wastefulness as they often dump anything deemed trash, including criminals, into a massive dump site below the town known as "The Pit". Rudo was told by his foster father, Regto, that his biological father was dumped into The Pit for a crime before he was born. One day, after rummaging through a dump site, Rudo returns home to find Regto dead. Apprehended at the scene, Rudo is immediately charged with murder despite his innocence, due to his status as a tribesman. Unable to escape his fate, Rudo swears revenge upon the people, and is dumped into The Pit. After being dumped into The Pit, Rudo awakens to find himself disoriented in a foul-smelling, endless landscape of trash. Rudo is then attacked by large beasts made of trash, and fends them off until he is rescued by a man named Enjin. The man explains to Rudo that he is in fact not underground, but has fallen to the surface from "The Sphere". After testing him and awakening his power as a "Giver", Enjin invites Rudo to join him as a "Cleaner". Enjin explains that the Cleaners are an organization of Givers who use the power of unique weapons known as "vital instruments" to hunt the trash beasts which attacked him. Rudo reluctantly accepts Enjin's offer to join the Cleaners, so long as it helps accomplish his goal of returning to The Sphere and enacting revenge on those who dumped him into The Pit.
In the hyper-policed, sterile metropolis of Vector City, a totalitarian regime known as the Vector United Authority (VUA) rules with an iron fist. Led by the charismatic but corrupt Director Gordon Vane, the "rotten adults" of the city are systematically siphoning the city's underground Ley Line energy, draining the vibrant culture, memories, and very souls out of historic neighborhoods and transforming them into lifeless, grey corporate blocks. Zack Ridge, a normal 16-year-old high school kid just trying to survive his classes and get home to his loving parents. Zack's life is completely shattered when Director Vane personally frames him for a brutal assault he didn't commit, using the VUA's absolute media gaslighting networks to broadcast his face citywide as a dangerous delinquent. On the run from the hyper-aggressive Paranormal Police and automated H.O.U.N.D. Drones, Zack is rescued by Professor Sprocket Locke, an old-school, eccentric mechanic who runs a neighborhood parcel shop called Sprocket Express as a secret front for an underground rebellion. Recognizing the fire and defiance in the kia, Sprocket clamps a blocky, industrial prototype onto Zack's arm: The Spectral Gauntlet. Powered by Zack's internal fury, the gauntlet taps into the city's supernatural currents, supercharging his Vector-Drive Inline Skates with physics-defying speed and kinetic energy. Joined by his fast-talking, comic-relief best friend Felix "Flea" Greene and a cool, mysterious Japanese transfer student named Haruka "Haru" Sakamori, they officially form The Ground-Line Riot. Operating right under the noses of the corrupt adults, the crew takes on high-stakes, high-velocity delivery runs for Sprocket Express to smuggle vital data and rebel tech. By mastering supersonic rail-grinds, wall-rides off skyscrapers, and momentum-fueled kinetic strikes, these rebellious kids are determined to shatter the VUA's monochrome illusions, restore the vibrant color to their streets, and put an end to Director Vane's oppressive machine once and for all!
