Roman listened intensively, his eyes locked onto Freya's as he absorbed every word. He questioned whether, after reaching S rank, there would be other stages or not, but Echo Freya only smiled enigmatically, saying that he should reach S rank first, and then he would know.
"Forming the core is a crucial step in your development, Roman," Freya emphasized, her voice filled with a sense of urgency. "As a half-Nymph, your body lacks the natural connection to nature that full Nymphs possess. This core will serve as a substitute, allowing you to harness and control your powers more effectively."
