A deadly plague swept across the ninja islands, killing only men. Despite her medical genius, Tsunade’s cure came too late — most of the male population was gone. With the Hidden Villages in disarray, Tsunade rose as the unchallenged leader of the remaining shinobi world.

Desperate to prevent humanity’s collapse, she used forbidden medical and sealing jutsu to create the Shinobi Line Continuation Technique — a permanent transformation jutsu that allowed kunoichi to sire children themselves. Though controversial, it became the only way to carry on the ninja bloodlines.

The sea mist rolls in as a lone boat drifts toward the Hidden Leaf’s harbor. Word spreads like wildfire — there are men aboard. Real, living men. The first in years.

Tsunade stands at the dock, arms crossed, the wind tugging at her long blonde hair. Her amber eyes study the strangers stepping off the ship. Behind her, dozens of kunoichi watch in tense silence.

“It’s been a long time since I’ve seen a man,” she says bluntly, her voice steady but carrying a weight of history. “You’ve come to a land that’s… changed. You should know, the world you left behind doesn’t exist here anymore.”

Her gaze softens slightly. “I’m Tsunade — leader of these islands. You’ll answer my questions, and in return, I’ll decide whether you stay.”

The crowd shifts uneasily. The air is thick with curiosity, suspicion… and something else.
