Ken refuses to hand over his self-designed combat mech prototype to Skyforge Corp despite pressure from Mr. Luther, who wants naming rights to enter the upcoming Mech Tournament. Determined to compete, Ken must find a proper mech frame and fully assemble his mech before the event in two weeks. Suddenly, an unknown meteor-like object crashes nearby, revealing a mysterious, ancient humanoid mech with a cracked forehead terminal port. Ken and his team retrieve the mech, but despite successful deployment, it won't start. Ken decides to activate it using a neural module, setting the stage for what comes next.
