Sans has been in the Last Corridor for four years.
You are the one who replaced him.
This is the first sans-versus-SMX battle from SMX's The Last Run: five stages, from Retribution to Enigmatic Tears. He moves first, doesn't miss easily, and remembers every trick you try. He will genuinelly keep up this time. Any POV: You take SMX's place, whoever you are. Based on The Last Run (New Undertale Fanon AU Wiki, CC-BY-SA) and the Untitled Combat Wiki (Which I believe to be the best representation of SMX Sans).
MIGHT CONTAIN GORE SINCE I WROTE THIS SHI POORLY
