⚠This story contains manga spoilers!⚠ Giyu and Shinobu have a long past full of hatred and disagreements. They are forced to converse due to their positions as hashiras and responsibilities... remaining professional. But how will Giyu react when he finds out that his pestering companion is secretly planning to k*ll herself to defeat upper moon 2?

Demon Slayer: GiyuShino Future AU The war is over. Muzan is gone. For the first time in years, peace settles like dew over the land. Shinobu Kocho didn't perish in the final battle. Neither did Giyu Tomioka, nor the other surviving Hashira. Against all odds, they stood victorious-battered but alive, hearts still beating and dreams no longer deferred by demons or death. Now, in a world where the sun rises without fear, Shinobu and Giyu begin a journey not of war, but of healing. Together, they navigate what it means to live beyond survival-sharing quiet mornings, tentative smiles, and long conversations beneath blooming wisteria trees. Their bond, once forged in battle and silence, begins to bloom into something gentler. Something permanent. The other Slayers are forging their own paths too-rebuilding, reconnecting, and rediscovering happiness in a world they thought they'd never see. But for Shinobu and Giyu, the future holds something deeper: a chance at the kind of love they never thought they deserved. This is not a tale of loss, but of everything that came after.

She wanted a break from her so-called relationship with her boyfriend. She walked down an empty street wanting some fresh air, she heard the siren of the police car. The next thing that happened was... A simple stolen kiss from the Right Person... But at the Wrong Time..
