(Y/n) Hitachiin is the older sister of the twins, Hikaru and Kaoru Hitachiin. She used to live in America with her father, but has come back to Japan as a student at Ouran High School. All (Y/n) really wants is to get through high school and take over her fathers business... but things don't go quite as planned when she stumbles upon an abandoned music room, and meets an annoying Shadow King. As time passes, she becomes unsure of what she truly wants. Will she take over her father's business, or will she follow her heart?
