    Summary

    Your stomach rumbled. Making you move ever so slightly. It was nearing your feeding time anyway. You ever so slightly lifted your head off of your battered arms to give an ice cold glare to the glass window that separated your room to the rest of the asylum. The glare you were currently giving the window was one of those glares that could render a full grown man helpless. You smirked once more at that thought. Though this time, your smirk was plainly visible to the people currently monitoring you from the safety of the other side of the glass window you were currently looking at. That's right. They were safe from you with being on the other side of the glass.

    Things to look out for:
    ~ Blood and gore
    ~ Mentions of violence
    ~ Cannibalistic notions
    ~ Horror topics
    ~ Upcoming intimate scenes

    WARNING: This story is very graphic, and not for the faint of heart! There are mentions of upcoming rape scenes, graphic depictions of violence, profanity, and a whole lot of blood and guts. This is rated M for a reason. If you have not already read the summary for this fanfiction, I highly suggest that you do. You have been warned, read at your own risk. This is geared for mature audiences only.

    Summary

    It's been a year and a half since she left, after the first Genocide run. Sans finds himself every day missing the love of his life, Frisk, more and more. His mind is deteriorating. He has started seeing someone who isn't there. His father. Voices fill his head. Constantly driving him towards the edge. The demon has cut down to completing her genocide runs within 2 weeks. And this has become his life. Fight the Demon, kill the demon, restart and repeat until he dies.

    It wasn't Frisk's fault. She wasn't the one who killed everyone. She wasn't the one who killed all the monsters she'd come to love. But She Killed Herself with Guilt regardless. And it's driving Sans insane.

    We're going to see a new side to the skeleton we love.
