"Your mine. No one else can have you." I don't own Maid-Sama or any of the characters

Light has a goal of making the world a better place by killing off all the evildoers using his Death Note but what if a girl is also in the possession of a Death Note with a similar goal in mind? Cold-hearted (y/n) is out seeking mayhem and lets no one get in her way. So what happens when she comes across a couple of boys who make her go soft? With so many secrets, will (y/n) side with justice or love? ~Reader's POV / first person~ ~ highest rank : #1 deathnote / #2 Lawliet
