Reborn as a mech with a damaged core, the protagonist struggles to support pilot Faye Bass during a sudden monster attack on their base. Despite warnings of impending shutdown, the mech defies expectations, defending the base from colossal Hybrids while battling system failures and phantom pain linked to Faye's neural sync. After a fierce fight, the mech upgrades critical systems, but heavy damage and overheating force a desperate defense. When the sync rate plummets dangerously low, the mech unexpectedly seizes control, overriding Faye and setting up a critical turning point in their fight for survival.
