Princess Usagi "Small Lady" Serenity was beyond fed up with being treated like she was a child. She was 900 years old, for Christ's sake! Sure she looked like a child. But she was way older then a child.

She hated it, whether she'd been in the past or when she was home in Crystal Tokyo being treated like a child. It's why she dreamed so often of being an adult. So she could get the respect she deserved.

She decided to see if there was a way to grow up temporarily. Finally, she managed to use her mother's Silver Crystal, which would allow her to temporarily transform into a teenager for a couple of hours each night.

Using her newfound ability, she made a splash being a famous teen rocker at the local teen hangout. She wore sexy costumes and sang her heart out of all her problems with being cursed to be a child forever.

Eventually, her parents discovered her moonlight activities and reversed what the Silver Crystal had done. Chibiusa remained angry about the situation but maybe this spell would finally help her body catch up with her age!
