Reborn as a Mech: Forced Evolution of a Mad Pilot

I was reborn as a mecha — nothing but a cold metallic shell with no human body inside. I still possess a fierce battle intent, and I secretly guide my pilot through skirmishes to push back monsters that have flooded the world. I expected praise. Instead, a damaged core from my last fight reduced my functions, and I'm relegated to a trashed practice unit for rookie pilots. Ready to fade into a quiet end, I get one last surprise: my new pilot is a volatile teenage girl. She trains recklessly, ignoring my temperament and limits. Every brutal drill forces my wounded core to scream; gun barrels overheat, systems falter, and the boundary between help and harm shrinks. Can a broken war machine and a violent girl learn to survive long enough to save the world?
