A classified mission sends Japan’s top pro heroes to a newly emerged, quirk-distorting island believed to be a villain stronghold or living weapon, only for them to uncover a hidden forest civilization untouched by modern hero society. At its center stands the island’s leader—the “gem” of her people—a woman bound to the land by a rare transformative quirk that allows her to merge with the living ecosystem itself, acting as both protector and anchor of the sanctuary. What the heroes perceive as a threat is revealed to be a self-sustaining barrier designed to repel exploitation, forcing them to confront the consequences of interference rather than combat. As tensions rise between duty and restraint, Hawks finds himself unexpectedly drawn to the one person least aligned with his world: a rooted, unyielding leader who sees past his wings and reputation to the man beneath, challenging everything he has ever been taught about freedom, choice, and what it truly means to protect.
