Love is just a word until someone gives it meaning~ Karma X Reader

(Y/N) is Ryoma Terrasaka's twin sister. What happens when (Y/N) gets moved down to E Class?
Ryoma is more genuine with his twin. You are seductive, ill-mannered, smart, tough and is genuinely adorable.
You are just shorter than Nagisa so your twin is twice your size but you still protect him.
You don't obey rules and you want to kill that octopus at all costs. For Ryoma and somebody else...
(Y/N) has a sibling complex and is only really used to her brother since their parents left them.
You are both 16.
