----------------------------------------------------

You twisted under Sans magical attack. Spitting blood at his face when it splattered you laughed at him. Chara had taken ahold of you, and there was nothing he could do but, attempt to stop you from coming any further. You were once so beautiful, and bright now just a disgusting human who wants to kill everyone on sight or on the command of your new so-called friend.

"FIGHT ME!" You screamed at him, as he rose his shaking hand to you sending your body flying to a wall just beside him. When your body went limp he could hear you crying as you reset to your save. You wanted this to end, though he knew you had given up like he did a long time ago. He couldn't afford to give up anymore. As he stared at your lifeless (e/c) eyes that began to have black goo form at the corners falling down your face he quickly turned away putting a hand over his teeth to prevent him from gagging. You honestly looked like some horrible abomination that should be eradicated. Looking up at you he saw your hand clench the blade tightly as you threw your hand back blood splattered onto the walls in a lined pattern. Did he really do all of this just to die? Again, and again whenever you hit reset you did the same route making him suffer again, and again. Sometimes sparing everyone or, if it bored you killing every single person he loved till the last monster child in the underground. You even killed Flowey, sure the weed was annoying, but even he'd let them live in misery by letting him live.

Looking up he saw you running at him he kept dodging over, and over again until sweat beaded off his bones. He was growing tired, and weak you were beginning to learn his pattern. So, he tried changing it around. Nothing worked he knew you'd kill him until he saw you freeze gasp in pain.

"S...sans.." you said extending your hand to him, "K... kill me.." it didn't take you telling him twice to send bones that speared every part of your body with holes. Though again you kept coming back, you began trying to end your own life just to have Chara revive you. You were done with fighting you didn't want to kill anyone anymore. They weren't having it though, Chara wasn't going to let you just go and disappear oh no they wanted you to suffer. So they made you watch as they tried to strike down your best friend the one you held so dear.

"Oh god (Y/n) grow up, you want this comedian as dead as I do!" They said.

"T.. THAT'S NOT TRUE" You yelled back at them as they swiped at Sans.

"Not true don't make me laugh, so you killing everyone he loved wasn't because you were bored?" They laughed, "You're so pathetic." Sans tried changing up his fight several times nothing was working, and he knew his life was going to end soon. As Chara turned around Sans shot his hand high in the air making them go stiff as bones pierced them lifting them high off the ground.

"Get dunked on you megalomaniac." He muttered as he twisted his wrist to try, and ease the pain. You looked at him banging on the glass as you cried why did you do this. You were so sorry, and you didn't know what to do.

"What you should do is just die!" Chara said tackling you to the ground in the black void that you both shared. They slammed you down wrapping their hands around your neck as your soul floated above your body.

"Kiddo?" Sans let his voice ring out as he extended his hand to your soul he began examining it curiously. Two buttons showed behind him, SAVE or RESET. He blinked at them not being able to process what was going on, "So the brats soul was the key?" He chuckled.

Chara lifted their head glaring at Sans in rage, "Give that back you comedian!" They screamed as you tried to crawl away equaling in Chara stomping on your chest. "Look what you did!" They screamed stomping on your stomach now as Sans watched for a while before he flung them off.

"Alright, playtime is over, since I'm in control now neither one of you is getting a happy ending for a second chance." Your smile fell as Chara tried to attack him only to fail, "I mean sure you killed everyone, but.." he tapped his jaw, "This shouldn't be in the hands of such a small child." He grinned, "Right (Y/n)?" Kneeling down to your fallen form he brushed the hair from your face, "Seyah in hell doll." He stood up waving before he slammed his fist onto the RESET button.

You were dead, and Chara was nowhere to be seen. The game was played like normal you never existed ever again.
