Chelsea is a brunette like her mother. She is somewhat scrawny for a girl her age with small breasts and curvy butt. She tries to work out but tires quickly. Her quick temper has become legend to those around her. She can find nearly anything to get angry at. While her rage could probably send a tiger up a tree, her body can’t seem to put words into actions. It’s unlikely she could win any fights against her classmates which is why most of them find her to be just a pile of hot steam. Manipulation isn't her forte either; in fact, her feelings tend to leave her blind to the most blatant traps.

Chelsea's mother, Katie got married and has two children, Chelsea and William. She and her husband grew apart for various reasons and now try to fund their children’s living expenses separately; leaving the two kids to fend for themselves.

Katie's ex-husband is second-in-command at the security to a local theme park and takes the kids there frequently.

Katie started working at some corporation a few years back but never discussed her job description at home. In fact, she hasn't said the word “job” in about five months. All we know is that Katie relies on Chelsea to man the house until she returns. This tends to be from 9 AM to about 2:30 the next day. At least it pays well.

However, Chelsea has been keeping a secret with her since puberty: a separate personality who loves to toy with her sexual frustrations. Nearly every minute of the day, Chelsea can feel this presence with her that she can talk to with her mind. What is said in her mind can be summed up as one-sided bickering but there are some cases where the voice can coerce Chelsea to do some pretty raunchy and risqué things. Even though, she struggles to manipulate others, Chelsea has proven that she can at least manipulate herself.
