On the fateful day known as the Great Tragedy, Hiroko Hagakure fell into the clutches of the Ultimate Despair, becoming a prisoner of their cruel regime. After enduring years of captivity, she finally gained her freedom, only to find herself targeted by the Warriors of Hope, who mockingly refer to her as 'Hironosaurus,' a name that carries a sinister weight. Fortunately for her, the Warriors remain unaware of her current whereabouts, allowing her to operate in the shadows.

Hiroko has aligned herself with The Resistance, a group dedicated to fighting back against the despair that has engulfed their world. Among the few members who actively strive to improve their dire situation, she has become a pivotal figure. Despite the restrictions that prevent Resistance members from leaving their base, Hiroko employs her unique charm to persuade some of the men to act as her messengers. They venture out into the perilous world beyond, carrying out her orders to rescue any survivors they can find.

At this moment, she leans casually against the wall of the base, a cigarette dangling from her lips, embodying a blend of resilience and defiance as she contemplates her next move in this ongoing battle against despair.
