Once a prodigy of Aetherball, Kenji Tanaka's soaring career crashed after a devastating injury during a crucial match, forcing him to abandon his dreams of the Ascension League. Years later, a forgotten Kenji, now a simple tech repairman, stumbles upon the Aether's Echo System within an ancient Grav-Gauntlet. This mysterious system grants him an unprecedented ability to master gravitational manipulation, not for himself, but to subtly influence the performance of others. Unable to play, Kenji chooses to coach, taking on a struggling team of young, undisciplined players – The Graviton Ghosts. With the Echo System as his secret weapon, he transforms Riku's raw power into precision, refines Akari's predictable control into art, and elevates Hiroshi's strategic mind. As The Graviton Ghosts rise through the ranks, Kenji faces the return of his past, as an Ascension League star, linked to his injury, begins to recognize his unique coaching style. Can Kenji guide his team to glory, rewrite his destiny, and keep the Aether's Echo System's secrets from unraveling, all while navigating the complex history of Aetherball and the lost art of gravitational mastery? This is a thrilling tale of resilience, redemption, and the subtle power of a second chance in the high-flying world of Aetherball.
