Backstory: She grew up in an urban town and was always being bullied at school by every student there and not a single one was nice to her in the slightest. She was perfectly normal as the other students were so she had no idea as to why she had been getting bullied. She eventually got to the point of getting used to the names and hits she took in school, so she became immune to physical pain. Later on, she ended up going on a murder spree of others.
