I Get Stronger by Getting Hit

Trainee prison guard Nox awakens a System making him stronger by getting hit after a D-class Anomaly attack. Taking damage allows him to stack defense, resistance, and abilities. He provokes Anomalies, subjugating B-class and A-class ones. Finding them too weak, Nox refuses a transfer. He joins The Capture Division with Lee, heading to the Barrens to hunt high-level Anomalies. He defeats S-class and SS-class enemies, learning talents like replication and insect control.
