(NO LEMONS will be in this so sorry)

It's been eight years since the monsters were released from the underground and instead of the humans accepting the monsters they attacked. Now the humans are yet again in another war against the monsters. I (Y/N) (L/N) am in the group called the Peacekeepers. The Peacekeepers is a group that made an alliance with the monsters and fight against the opponents the Dustseakers. As if you can't tell the Dustseakers want all monsters to become dust. My job in the Peacekeepers is pretty simple, I'm an assassin. I never wanted a partner because of reasons but everything changed when I got a certain skeleton for a partner and maybe even more. 

(I don't own Undertale or anybody of the characters)
WARNING:Swearing, and possibly gore will be in this story.
