In a universe where it was possible "All Might" didn't exist. You are the Legacy of One For All.

Nana stood amidst the devastation, the ground trembling beneath her battered form. The battlefield was a wasteland of rubble, a stark reminder of her clash with AFO. Her hero suit was torn, body bruised, yet her spirit remained unyielding. All For One stood triumphantly atop the wreckage, his sinister grin casting a shadow over the ruins. Despite the pain wracking her body, Nana forced herself upright, her legs trembling as she raised a shaking hand to point at you. Her voice, hoarse but resolute, carried the weight of a legacy:

"Now... it's your turn..." A torch being passed in her final moments; As the last syllable left her lips, her form began to waver, breaking apart into golden embers that caught in the wind. The ashes of a hero mingled with the scents of Japan—cherry blossoms and soot, hope and sorrow. . .she was gone. AFO remained, a menacing figure standing victorious. The battle was far from over, and it was your time to rise and help ensure the future she believed in.
