need some help for the idea for the story

A 19 year old boy with a bad past is about to end it all when a portal opens up below him and he ends up in hell in the helluva boss world and is still alive and meets a hitman group called I.M.P which helps him and he changes them from their murderous ways and change them to kindness to change hell for the better and to have faith in God

Also I do not own any of the images or characters from Helluva Boss or Hazbin Hotel
