They're identical, but only on the surface.
Emi is rebellious, outgoing, athletic and has a horrid temper. Eri is quiet, booksmart, and easy-going, if not a little gloomy. The twin sisters have gotten used to depending on only each other. Using the excuse of it being "better" for their studies, they haven't lived in the main house since they were quiet young, and as a result, rule themselves. When Emi's wild nature results in her "choosing" to leave Lobelia, the girls transfer to Ouran for a fresh start.
Unfortunately, this fresh start becomes entrenched with a horror from their past, bogged down with the return of their estranged brother, and a bit wild when combined with a host of new friends.
Whether its good, or bad, as the horror grows stronger, so do their friendships. If one good thing comes out of this adventure-- it would be that they're no longer in it alone.
**This is a rewrite of Double Trouble**
For their whole lives, the world was only split up into two types of people: them and everyone else. Hikaru and Kaoru Hitachiin have only relied on each other for the time they have been alive. When they met the school's chairman's son, Tamaki Suoh, they only thought he was crazy; but still got them to join his new club. That was when Kaoru met him. Unknowingly, Tamaki's best friend, also the vice-president of the brand new Host Club, had Kaoru's mind spinning and reeling over new feelings that he had never felt before. Will Kaoru even allow for someone to enter his own world that consisted of only him and his brother? How will he respond to these new emotions? How will Hikaru react to this new development?
