ZERO RANK Gates spawn monsters, and the Hunter Association ranks the awakened E to S by their mana output. Kang Ijun is the only person in history to measure ZERO — Rank 0, the weakest hunter alive, working as a porter for E-rank raid teams. But the crystal measures mana — and Ijun's power isn't mana. Every wound he survives changes his body: denser bones, faster nerves, sharper eyes. The Association can't rank adaptation. "The crystal measures what you are. It can't measure what you're becoming."
