Y/n was a top tier Assassin. But what happens when Hell's ruler, the Devil himself, asks him to complete a list of targets in Hell against his business, I.M.P.? Although things in Hell seem almost normal, there are Templars hidden in the crowds. Y/n needs to be careful otherwise the Templars will be after him and blood will be spilled.... I do not own Hazbin Hotel or Helluva Boss All characters, unless specifically stated, are owned by Vivziepop.

With the help of the I.M.P along with the power of the grimore that grant access to the mortal realm to take care of people's unfinished business when they were alive. ( I DONT OWN ANYTHING IN THIS STORY EXPECT Y/N )

Yeah I couldn't think of a better name sooooo ye heres the helluva boss story

Y/n Is a fairly nice guy, goes to a good college, has a decent job but he's been mostly alone ever since his parents died due to a drunk driver crashing into them. After finishing a late shift, he was walking home in the middle of the night because some jerk stole his bike. While watching his phone, he didn't notice the scenery beginning to warp around him, he finally look up and check his surroundings, all he said was: "Ah, crap here we go". A/N : This is my first story ever, please be somewhat gentle with my dumb self. A/N 2: I don't own a thing here beside Y/n and maybe some Oc's. A/N 3: Not the best at English but I'll at least make sure the words are spelled right.

Y/N was once a normal guy. He had a great job a nice life a beautiful girlfriend. One day it all went horrible. You arrived home from work when you opened your door seeing your beloved girlfriend cheating on you. I'm anger you killed her and her new boyfriend. And was able to hide it for a long time. Till it happened again as you had a history of your girlfriends cheating on you and you ending up snapping. One day you last girlfriend had a plan as she knocked you out and fucked her new boyfriend in front of you and shot you in the eye killing you. You weren't surprised when you ended up in hell seeing as you committed great sin's even if it was in a fit of rage. However those heartbreak and betrayal opened a part of when you were in hell. A new power. Beware of Y/N The Shadow Demon he hears, see and smell everything in the shadows.
