Tsukino Usagi is a 14 year old high school student who is as kind-hearted as she is ditzy. She is known as a cry-baby who is only concerned with all the things normal teenagers are troubled by: getting good grades in school, chasing boys, and watching her figure despite her ferocious appetite.
However all of that changes when she encounters a talking black cat named Luna who reveals that she is not as normal as she thinks and has bigger things to worry about than the annoying but handsome guy she can't seem to stop running into who insists on calling her meatball head. Luna gives Usagi the power to transform into a Sailor Soldier, a warrior against the dark forces of evil, and Usagi must overcome her childish ways to take on the responsibility of becoming Sailor Moon.
