Third POV:
It was late at night and here Y/n is currently watching her favorite anime called Demon Slayer while reading The Promised Neverland manga.
"I wonder if they could have a crossover, it would be great. I mean these two animes have demons in it." Y/n sighed.
When you finished watching Demon Slayer and reading The Promised Neverland manga Y/n started to feel sleepy. She closed her laptop and headed to go to her bed to get some sleep.
"I wonder if my wish would come true..." Y/n said drifting to sleep.
What Y/n didn't know that her wish would come true but with a twist.
Y/N opened her eyes to see darkness, she was walking around to see if anyone is there.
"Hello! Is anyone there?" You asked still walking around.
You stopped walking and saw a light. You walk over there and you heard a voice.
"What is your wish, my child?" A voice said.
"My wish? I wish for (something you want)" You said.
"Very well... Who is your favorite character on Demon Slayer?"
'My favorite character?' You said in your head. 'Shinobu? Mitsuri? Kanao? Ah! I know it's...'
"(Your favorite character) " You said.
"Ok child, I'll turn you into Nezuko Kamado" The voice said.
'Wait- this wasn't part of the deal!'
"What-" You were cut off by a bright light and your body is glowing. Then you open your eyes to see that you look like Nezuko.
"Woah! I became like Nezuko!" You said with a shock expression.
"Now child, I'm going to bring you to the anime The Promised Neverland. Good luck" The voice said and the light was gone.
"Wait! Come back here! I have a lot of questions to ask-" Soon you blacked out.
"Welcome to The Promised Neverland Y/N L/N"
"Good luck on your journey"
