A land under the hill

Nobel, she was a nobel, how did she end up as a nobel? one minute she was being interrogated by the police and the next she was being shipped off to japan saying she is a child of a noble family, the hitachiin family. She will be attending school with her brothers, who by the way made them triplets, at Ouran Academy. The catch though? she has fractured memories of her time before the streets. Are they real? are they fake? and what about the shadow she keeps seeing?
