Lucifer thought it was about time he helped you get revenge on those people, whom treated you badly. That's the whole reason you sold your soul anyways, and he was willing to give that chance once again. When he went to the overworld, going to the Halloween party(that the people were in college were), walking into a random room. He started making the ritual, the pentagram in the middle of it flashing a brief moment of cherry red.

He smirked, now he knew you were more then ready to take revenge. He then made his out the room, to the stage in the middle of the house. He started to sing the song that was the way you could find the place to go to, and to distract all the partying people in the party rn.He started to smirk evilly as he strung the strings on his guitar, getting ready to sing.

♪"There was this girl, the most beautiful in the world. She had the boys in town wrapped under her finger, ohh."♪

He chuckled into the microphone softly as he saw you wave to him in the background, having your blood stained knife ready as you slowly danced with some random people.

♪"She's a motherfvcking killer queen, she sold her soul at 17. A beautiful and broken mess...She'll fill your heart with kerosene. And light you up 'til you can't breathe."♪

He continued singing, trying to distract everyone as you slowly locked all the doors and windows. He also saw as you stabbed the cake, taking a bite of it. He tried to not laugh tho.

♪"She's the one and only, KILLER QUEEN!"♪ He still continued to playing his guitar as you brutally stabbed everyone to death, one by one. He laughed into the mic as he saw you again take a bite of cake before stabbing the last person.
