Ivy was born.. Different. She was quieter than other kids. She was emotionless. She felt broken and empty inside. Her last bit of happiness died after her brother.. Well... Died..
She never felt anything. She was a common target of bullying due to her disorder. Its kind of like a curse.. One kid from each brach of the family had a problem with them. Ivy was unfortunately the kid who had a horrible disorder. She never understood what was wrong with her, even when her parents tried to explain. She felt as if she was just alone, and no one cared for her.
After something similar to what happened with Ayano Aishi happened, she became obsessed with the person she bumped into. That is what turned her into a yandere. However, the last two sentences were what happened when she was in highschool. She is about 7 right then..
