[TOMT] japanese horror film, 2010s

so i can remember what the plot was but not the name of the movie and i want to rewatch it 😭 spoilers for the movie. i know it’s probably a 2010s film and i’m like 90% sure its japanese. takes place in a private all girls school. it was horror or suspense depending on how you look at it, it was on Netflix when I watched it!

so basically the plot starts of with this sick girl who is moved into a private school and she has basically replaced a girl who recently “moved away” so everyone lowkey hates her except one girl who’s nice to her

after some bullying, the head mistress starts giving her medication for her illness but it works way to well, like now she can do a long jump and land 12ft away. and this not only makes the other girls jealous but also like wtf???

so turns out the head mistress is actually a scientist for the koreans and has been turning girls into weapons that she sells off. so the two girls decide they need to leave asap, and they try but one is caught by the head mistress and put into a tank in her lab. the girl who jumped super far freaks tf out and goes on a murder spree to find her friend, after killing everyone she finds her friend in the tank and breaks her out. sadly the girl is dead already but she takes her body and leaves.
