Affinity: Chaos

Affinity: Chaos follows Grey, a kid written off by everyone because he has no elemental affinity—until it’s revealed he has one for Chaos, a rare and unstable element no one really understands. It’s a classic underdog story: he trains hard, takes hits, and earns his place step by step. The fights are unpredictable, the friendships feel real, and while the writing starts rough, it improves over time. Nothing groundbreaking, but a solid, satisfying read if you’re in the mood for something straightforward and rewarding.

I really enjoyed reading this novel a long time ago, but the rate of chapters coming out is excruciating so I recommend stacking chapters so you aren't waiting eternally like me 😭

I haven't come across a similar power level name system that's only just the humans. All in all this is story is good just wish there will be more chapters in a week
