Sans x Marinette x Underswap Toriel

Sans was fighting the kid in another genocide route when a portal opened and sucked Sans inside Sans wakes up in a security office and explores to find the Fnaf robots but one has an eye on him and the same can be said for him will they admit their feelings or will he die on the 5th night?Or with new powers is he going to be able to ally with new allies or die to Insane Ink and no one steal my OCS only if I give you permission to. Or with the powers of the Insanity souls will Nightmare Freddy join Insanity Ink or join his brother Shattered X. ( Plot twist right there) Different au than my first book but similarities between both of them can be found. There are other ships like

Dream killer x siren trio of Equestria or Dream killer x Dust

Oh and none of the pictures are mine
