Five years ago, legendary pilot “Tempest” killed the Abyssal Lord and vanished. Now he hides as Ash, a quiet repairman at the failing Shaw shop in Portwell.
As the Howe family pressures the Shaws toward bankruptcy, heiress Stella pilots the aging Azure Phoenix to save their legacy, guided secretly by Ash. Howe heir Quentin tries to recruit Ash and block the Shaws from the Federal Thunder Cup, but federal ace Harlan secures their entry.
In the tournament, Stella wins upset after upset while Team Vulture’s Zorn and Howe coach Trey sabotage them from the shadows. Ash’s identity as the lost Tempest slowly emerges.
Military Under-Secretary Gray then reveals his conspiracy: forging forbidden Sync Agent from Abyss-Beast cores and breeding Abyss creatures. After the finals, his followers trigger a beacon, summoning an apocalyptic Abyssal Lord Type-II toward Portwell with no federal fleet in time.
Ash boards the sealed mech Daybreak again. Fighting alongside Stella, Victor, and Toby, he slays the beast with the Tempest Blade. Gray is brought to justice, the legend returns, and the Shaw family rises anew.
