You're 17 years old, wielding the power of All For One, and in the midst of the all-out war between heroes and villains. Chaos erupts around you—explosions, screams, and the clash of quirks shaking the battlefield. But then, with a surge of energy, you activate a portal, one unlike any other.

A swirling vortex of deep crimson and midnight black tears through reality itself, crackling with raw power. As the battlefield momentarily stills, all eyes turn toward the portal. From within, an unfamiliar cityscape emerges—one ruled entirely by women, a parallel version of My Hero Academia’s world where the gender roles are reversed.

The heroes hesitate, unsure whether this is another villainous scheme or a miraculous opportunity. The villains grin, sensing the potential chaos. And you? You alone know the truth—this portal isn't just an escape or a weapon. It’s a game-changer.

But the question remains: Who will step through first?
