Imprisoned Guardian [Naruto]

Emily Fuma, a young 12-year-old girl, who was known especially for her pale, flawless, ivory face, small distinguishing features, cerulean blue eyes and sunny yellow hair, and her talents in ninjutsu and genjutsu, apparently, is the last of her clan. Although she uses a happy facade in order to hide her loneliness, oblivious to that her guardian was imprisoned. It appears in her mind from time to time, and now she gets stuck in a team with a dunce, a somehow useless kunoichi, and a emotionless guy who doesn't care about anything, and last, but not the least, a perverted silver-haired, but powerful sensei. Will this be her new family, or will she join the Dark side?
