A seemingly cheerful girl who isn't aware of her life as a murderer...
Rosenna has a problem that even she doesn't know of. Doctors have never diagnosed it. They've never noticed. If you were to walk up to Rosenna during a regular school day, you'd see a sweet, innocent girl who is quick to smile and greet you. That is the part of her that everyone in school knows, the part that the teachers and her parent and the students know. The part of her that Rosenna herself knows. But deep inside her mind, Rosenna has another part. A different personality that is tired of being ignored. This personality is vicious, unpredictable, reckless, and crazed. This part of Rosenna is dangerous and out for blood, and now that it's gotten some, it only wants more....
Part One: Rosenna carries the average school supplies, pencils, erasers, notebooks, and textbooks. Nothing entirely special, other than a silver ring that her Grammy gave her on her birthday.
Part Two: This part of Rosenna is very literally a psychotic. This part, which, when Rosenna was little and her Part Two was just an imaginary friend, was called "Matty" carries a nice hunting knife stolen from the basement. With a hooked end for gutting. So far, it's been used once. According to Matty, it works quite beautifully....
Rosenna was born on December sixth, 1995. She grew up as an only child, even though she had had a twin brother who died at an early age. Her parents grieved for a while, but felt that they were lucky that their other child survived, which gave made them spoil her a little bit, but were still strict enough that she wasn't rotten. Around the age of four and five, Rosenna had gotten into the habit of talking to what they thought was her imaginary friend, whom she called Matty. Nobody was really concerned, because it wasn't uncommon among young children. As she got older, she got better. Or so they thought.it turned out Matty wasn't imaginary at all. Rosenna had an undiagnosed mental condition. Multiple Personality Disorder. Fortunately, it wasn't much of a problem, except sometimes Rosenna would go into a "mood" where she would be rather mean and snappish, which was direguarded as just teenage angst, the only thing taken as abnormal is that afterwards, she would never remember what happened when she came out of it. This began to happen more and more often. Suddenly, one day in school, a boy made Rosenna angry while Matty was in the dominant position. Later that night, Rosenna killed him. Later on, she didn't remember any of it, and cried when she heard the boy was missing, praying for his safe return, not even aware that she was the killer herself.
