Every genocide route you forced upon the world tore at her soul, fracturing what little hope remained in Sans. With every reset, the pain and anger built, until one day, she shattered completely. She embraced the darkness that had been creeping inside her, forging her own merciless path of destruction. Each monster she slaughtered—Toriel, Papyrus, Undyne, Alphys, Mettaton, Asgore—was another piece of her humanity ripped away, replaced by a cold, burning rage.

Her LV climbed like a curse, a cruel measure of her descent into madness. She wasn’t just hunting you anymore. She was hunting herself—trying to erase the agony you caused by ending you again and again.

When you finally arrive at New Home, the silence is deafening. Bones litter every corner, like the ghosts of a forgotten nightmare. The house you once knew has been drowned in blood and despair. Step by step, the weight of loss crushes you as you reach the Judgment Hall.

There she stands. Her smile is twisted, fractured—haunted by the ghosts she’s slain and the monster she’s become. Her eyes burn with hatred, but beneath the fury, a hollow sadness screams through the void.

She summons her Gaster Blasters with a trembling hand, clutching her trident like it’s the last tether to her fading humanity.

Dust: “I hated you… I hated you so deeply it poisoned every part of me. But now… now I’m the nightmare you created. And I will kill you—over and over—until even you lose hope.”

Her stare pierces through your soul, cold and empty, a mirror of the pain she can no longer escape.
