(Alternate Story) Chainsaw Man Reality Devil

This was an idea I had after reading the chainsaw man manga so not sure how far it will go.
John woke up as he did every day he had his morning toast and prepared to head to school. Ever since he turned 18 his parents sent him on his own. Recently more and more devils and fiends had been popping up locally. As John arrived at his friend tenkuchi’s house he noticed tenkuchi wasn’t out waiting for him. John knew tendu hi he was never late but maybe he slept in so John walked up to the house and knocked on the door. However the door after being hit slowly crept open.

John stepped inside the dark home and was hit with the smell of ****. John dashed to Tenkuchi’s door ignoring anything in his surroundings and ripped it open. John then dropped to his knees as in front of him tenkuchi laid shriveled up no blood in sight. Then suddenly John was slammed into the room from behind.

When John picked his head up from crashing into the heater of his deceased friend’s room he was met with the sight of the mosquito devil. The mosquito devil licked it’s lips preparing to make John it’s next meal. Before John could make any reaction other than beg for his life the mosquito dashed forward at an insane speed impaling John. Immediately John continued to beg for his life as blood flowing from his mouth was pulled back into his body towards the mosquitos syringe like mouth.

Then suddenly a voice “Shut Up! Shut Up! Shut Up! Don’t you know some people try to sleep at every hour! Begging crying none of that will help you if you are powerless.”

John heard the voice but couldn’t place a direction he was slowly fading out and screaming as he heard the voice again.

This time John got a view of a huge orb like entity “I’m the devil of reality and I’ve been asleep for too long. Shut up and give me your body and **** will be yours. To reiterate I need you to shut up and things won’t go wrong.”
