The story follows I.M.P. (Immediate Murder Professionals), a murder company in Hell.[5][6] The members are Blitzo (pronounced "Blitz"), the owner of the company, Millie and Moxxie, a married imp couple, and Loona, a hellhound who is Blitzo's daughter. Blitzo also has a tricky relationship with Stolas, a demon prince. Stolas has a book called a grimoire, which I.M.P. uses to do their job, because it allows them to access the human world.[7][8][9]

The series takes place in the same universe as Hazbin Hotel, but with different characters and stories.[10][11][12]


  • Blitzo (voiced by Brandon Rogers): The boss of I.M.P. He is shown to have trouble making friends. He was born into a circus, but he caused a fire that destroyed it and made the people in the circus hate him.
  • Moxxie (voiced by Richard Horvitz): The weapons expert of I.M.P. He is shy and sometimes does not like killing. He is married to Millie.
  • Millie (voiced by Vivian Nixon): The fighter of I.M.P. She likes to speak freely. She is married to Moxxie.
  • Loona (voiced by Erica Lindbeck): The receptionist of I.M.P. She is very rude, and does not respect the people in her life. She is Blitzo's adopted daughter.
  • Stolas (voiced by Bryce Pinkham): A demon prince. He owns a book called a grimoire, which can create a portal to the human world. He is in love with Blitzo, and does not understand why Blitzo does not love him back. He has a daughter named Octavia, and an ex-wife named Stella. Stella wants to murder Stolas because he cheated on her with Blitzo.
  • Striker (voiced by Edward Bosco): An imp assassin. He has tried to kill Blitzo and Stolas several times, but failed every time.
  • Fizzarolli (voiced by Alex Brightman): A famous imp performer, who works at a club called Ozzie's. He is dating Asmodeus, the prince of Lust. He and Blitzo were childhood friends, but after Blitzo caused a fire that destroyed the circus and injured Fizzarolli, he hated Blitzo. The two eventually make up and become friends again.
