TalixTale(Sans AU/Undertale)

A long time ago in a universe where a skeleton named Sans lived with Their older brother named Papyrus in small house that's falling apart by the second. Papyrus works in a cafe while being a royal guard and Sans helping time to time but Sans has his stand. Yes Sans and Papyrus are poor but not very poor where they have fight to survive. Sans hates humans to the point where they can't stand humans. A fallen human keeps on trying to fight Sans but after over 11,097 times of rests the fallen human named Chara gave up and tries to be friends with Papyrus and Sans but knowing Sans they don't believe that Chara has fully given up.

And he was right because Chara has killed Papyrus and attempted to murder them but failed. Leaving Sans while a chunk of their skull taken off and making Sans' Soul come out of his chest permanently. Sans stood up and use the last bit of their power to summon a gaster blaster to kill Chara before passing out while Papyrus' scurf in his hand. After Sans passes out Chara of course dies from the gaster blaster and turns in to a ghost to haunt Sans.

A few days later Sans woke up in the hospital with doctor Toriel checking over them. Doctor Toriel was glad to see Sans awake but looks at him with a sadden look before telling them about Papyrus and Chara. Of course Sans didn't care for Chara but broke down crying for the lost of his older brother. Nurse Undyne looks at Sans before speaking to them. Sans looks at nurse Undyne and Undyne told Sans that he can live with her. Sans smiles little before nodding accepting Undyne's offer.
