The trump card that should've never existed. Alice in borderland. Chishiya x y/n

Y/N is a good person, she sleeps in a lot and hates going to school but is a very smart person. Her mother had died when she was younger and her father is in the hospital on the urge of death so y/n usually spends time alone but she's always cheerful in fact y/n is a very kind person she smiles all the time even when she's mad or crying, she'll smile everyday even though no one sees it since she wears a mask for a reason... but y/n will smile until she dies because her mums last words were " even if your sad mad or someone picks on you smile your way through the pain" was her last words and y/n will keep that promise forever.

One day y/n was in the bathroom just doing girl stuff and all of a sudden the lights goes off and before she knew it the streets were completely empty and no one was found that was until she knew she had to participate in games to survive and return to the original world.

Just saying there will be some parts that aren't true but since there's a y/n in this story which also has powers it will change and the ending will also change so there'll be some different parts that probably never happened, and I get this is also Chishiya x y/n but it will only really happen at the end because it also focusing on the games and y/n herself but hope you enjoy reading this :)
Oh and there will be pictures that I kinda got from demon slayer and jujutsu kaisen like the clothes or the powers....like
Demon slayer= I used clothes and powers in this story
Jujutsu kaison= I used clothes and powers too in this story.

Forgot to mention!! But this whole story is Alice in borderland itself just my style and a y/n in this story so this story basically is a whole spoiler of Alice in borderland season 1. Oh and in this story your niragi's best friend in the past so just saying and now you can go ahead and read this book it's my first one so there will be things I have to do in the future but hope you enjoy it anyway :)
