A beautiful girl with a gorgeous smile. She thinks she doesnt look good but is very gorgeous. Amazing eyes and when she gets mad at you she just tilts her head and it just makes you feel bad for doing anything.

Sierra may seem separted from the rest of the world, but she has a ton of friends that always have her back. She is usually depressed and is an introvert. But.... she loves dancing (and is very good at it) and has very different tastes and styles than most people. If you have her as a friend, you are very lucky because she is one in a million! Also, she will beat up anyone who gets in her way or her friend way.
“Too bad you got that girl angry at you.”
“Why? What’s the problem.”
“Her friend Sierra will beat you up.”

A very funny girl who always had a good time. She loves her family and friends. She can be really weird but in a good way and is a really talented artist. If you’re friends with a Sierra, you’re gonna have the time of ur life!
