Oh, Yoo Ji Hyuk! That name takes me back. He's the lead from 'The S-Classes That I Raised', right? Calling him just a 'protagonist' feels too small. He's this guy who gets regressed back to his pre-Awakening days, but instead of going the typical solo-power-leveling route, his entire game plan revolves around raising and nurturing other S-Class hunters. It's a wild pivot.
He's less of a frontline fighter and more of a strategist, a guardian, and frankly, a master manipulator with a heart of gold. His power is weirdly support-based, letting him grow the potential of others, which flips the whole 'overpowered lone wolf' trope on its head. The tension comes from him knowing a future apocalypse is coming and having to carefully manage these incredibly powerful, often unstable, personalities to prevent it. The dynamic isn't about him being the strongest in the room; it's about him being the one who makes the strongest, and the psychological toll that takes is fascinating.
What really gets me is the parent/mentor vibe. He's constantly balancing care with calculation, and seeing these godlike hunters rely on him for guidance is such a satisfying power dynamic. It's a niche I didn't know I needed filled.
