If only... - Assassination Classroom Akabane Karma x Oc

Remi Asano was an un-wanted child. Her mother disappeared while her father--Gakuhō Asano--who gained custody of her did not need her at all. She was supposed to be kept a secret, a mysterious child lurking in his mansion...That was all she was, lower than any servant in the household. No one knew about her, and the people who did never acknowledged her.

But one day, a chance arrives. When her father assigns her to class 3-E to find out and report their secrets, she was more than willing to take it. She saw it as a chance to prove her worth, he saw it as a way to achieve his ideal school...But that did not matter.

Remi joins the class. But what she experienced there was more than what she had bargained for. Will she fit in? How will she fare in the assassination of the un-killable Koro-sensei? And, will she find love in the harsh world?
