In a world where parkour is more than just an art-it's survival, competition, and ambition-Renji Arata finds himself pulled into a high-stakes underground scene. Once a promising gymnast, a tragic injury and abandonment by his family forced him to survive in the streets, leaving behind his former dreams. But when the enigmatic Zeto Hagajima recruits him into a fierce parkour team, Renji is given a second chance.

The competition is brutal. Speed, strategy, and instinct define who rises and who falls. In this world, every participant possesses a Dual Core Ability-a balance between Instinct and Momentum, shaping their unique parkour style. But beyond that, there is something greater, Zero Shift, a state where instinct and movement merge into an unparalleled flow.

With rival teams, intense elimination battles, and shifting terrains designed to break the weak, Renji must push past his limits. He doesn't aim to be the best-only to prove he belongs among the greatest.

But in a sport where one wrong step means losing everything, can Renji truly rise again?
