The most brilliant, beautiful girl who was to ever walk the earth. The mere ground that she walks upon sprouts beautiful flowers in which life is able to thrive. She is more commonly known as an angel sent from heaven and is most of the time a blessing upon everyone she comes in contact with.

but if you happen to get on her bad side, she will destroy you.
