After Sailor moon hit her head in battle, she's been having memory relapses, or so she thought. What if Serenity's personality untied itself from Serena's and is now almost 'possessing' Serena, trying to find Endymion? Throw Sailor V into the mix, claiming she's the moon princess and you've got chaos. (full summary inside)

Serenity Lily Potter is Harry's twin. She grew up with a father and a brother. Their mother had passed and their father blamed her. She was brought up in misery and pain, mentally. She lost all of her friends but one because of her father, only to find out that her father isn't her father. At age 14, Serenity goes to Hogwarts to find a future she never imagined.
