jadejutsu kaisen: cursed killer

its a jjk fan game with its own fan made jutsu named jadejutsu

during the shibuya incident arc where after arata nitta picks her up and heals her injuries arata notices that she is dead and starts panicking but then realises with abit of help he can resurect nobara but after about 2 hours of trying they succeed but nobara looks confused but then she looks at her hammer and nails then arata swiftly looks at them but while they are looking at them nobara quickly grabs a surgical knife from the table next to her and stabs arata in which he falls to the ground but is still able to stand up slightly and hears nobara mutter the words メタリックヒスイ(metallic jade. pronounciation:Metarikkuhisui) then the nails and hammer explode with a some jade looking smoke then once the smoke clears the nails and hammer look like they have been turned to indestructible infinite resource jade but as nobara is going up to the table with her weapons on arata swiftly stabbs then kicks nobara nocking her down but when she gets up she grabs her hammer and nails and uses them to make attack at arata saying hairpin which then launches at the wall then destroying the wall then as she guess' that arata is most likely dead she walks away with the nail that she used coming back into her nail pouch calling herself the jujutsu killer while then also saying that she needs to look for mahito and yuji itadori but right as she exits the building arata gets up in which he calls her the jade killer.

and well this is my own version of what might of happened and even have nobara be the first ever jadejutsu curse user and even though this actually never happen i hope it will happen in the real anime (spoilers:not really the manga because apparently nobara has been replaced)
