Bio: A once normal girl that was "Created" and is now a Creepypasta. Sanity is sometimes a insane killing machine, but is mostly a calm murder in the night. At beginning, she was just a normal girl named Sanis, living with her sister and aunt. Her teacher had to move and was replaced with a new one. She always had this odd and uncomfortable around the teacher. Soon, students from her class and her neighborhood. After many disappearances, Sanis deiced to investigate and find out about this, but soon, gets caught. After she woke up, she found herself, on a table, being towed, by the person who's being kidnapping people, into another room. As she was being taken into the other room, the person tells her how he kidnaps people and turns them into animals. The person turns out to be her teacher. Later, she was attached to a heart-meter and was injected with this half-finished serum. She screamed then blacked out. The heart-meter beats rapidly then stops. The teacher thought she was dead and unstrapped her from the heart-meter and the table. Seconds after that, she woke up and killed him in blind. After seeing what she had done, she ran away from that place, then blacked out again in a wood. The next day, Sanis woke up and saw her " new parts ". Later, she was named Sanity because she's a insane killer who's sanity quickly returns after the death of her victim or something. Sometimes she will turn into her insane side ( Which is more powerful than her normal side.).
