-Chapter one-

At Ouran private high school academy; Everything was at its' normal routine especially with the academy's own host club. Each host club member were doing their normal routine of club activities and entertaining their customers. But then our lovable twins, Kaoru and Hikaru, decided to get Tamaki mad again for the millionth time. When they saw the club's hidden princess walking by and they started their plans.

"Hey Haruhi, Can you do something for us?"

Hikaru asked as he put his arm around Kaoru's shoulder and Kaoru doing the same to him. As Haruhi turn towards the twins and replied.

"Like what, exactly?"

Kaoru replied, instead of Hikaru, to Haruhi.

"Modeling our mother's new lingerie line."

Haruhi just looks at Kaoru and Hikaru, who were smiling like Cheshire the cat, with apathetic/deadpan expression. She was about to say something to them when Tamaki started chasing and yelling at the twins.

"Quit corrupting my little girl, you twin devils!"

While this was going on, no one was really pay attention to the doors when they were open by a twelve year old girl. she walked into the room, while closing the doors, and saw what was going on. Haruhi just sighs at the chase that was going on when she notice the pre-teen standing at the door. She walks towards the girl and about to greet her when the girl asked a question.

"Are they always like this?"

Haruhi got a pretty good look at the pre-teen before replying back. The pre-teen had long wavy milk chocolate brown hair ( three inches above her waist), average height, light skin tone, and she had two different colored eyes (right eye is green and left eye is blue).

(A/N: The pre-teen is wearing a black t-shirt with a neon green and yellow stars on it, blue jeans, and purple converse shoes.)

"It's pretty much normal for them to be like that everyday."

"I thought that host clubs were suppose to be serious and business like."

"They are... but we're a bit different type of host club though."

"I'm Haku, by the way."

"Fujioka Haruhi. Nice to meet you, Haku-san"

"Nice to meet you too, Haruhi-sempai."

Both of them shook each other's hand then continued to watch Tamaki chasing the twins. Haruhi was about to ask Haku on why she was there for but Haku wasn't next to her anymore. Kyoya was focus on his black folder, mostly checking the host club's expanses and income. (A/N: I wasn't sure if it was a black notebook or folder that Kyoya always had with him.) When he heard a familiar voice that took his focus away from the black folder.

"Kyoya~~~"

"Haku, What are you doing here?"

"Well...I wanted to see the host club and your friends that you told me about. Plus I wanted to see you as well, Onii-chan."

Haku hugged Kyoya by the waist while smiling at him and Kyoya returned the hug back to her, smiling. Everyone, in the club room, stopped what they were doing and became quiet in shock while just stared at the two before shouting.

"Onii-chan!?"

Kyoya and Haku saw everyone's stare while they could tell that everyone was still in shock. Kyoya decided to introduce his imouto to everyone because he knew that it was going to happen sooner or later.

"Everyone, I like to introduce you to my imouto, Haku."

"Nice to meet you all."
