I don't own Ouran High School Host Club.

The sister of Hikaru and Kaoru Hitachiin

"Right everyone! I have our theme for the Summer dance!" announced Tamaki, in his usual over enthusiastic way.

"And what could it possibly be this year?" asked Kyoya, not actually interested but wondering how much it could cost.

"Its..." Tamaki paused for dramatic effect "... A Beach Party!"

Haruhi raised her eyebrow "Isn't it at the beach though?" she asked

"Yes, of course"

"So its not a theme is it. Its just a normal beach party."

"... but this beach party is going to have live music and a buffet table!"

Haruhi couldn't be bothered to hold up her side of the argument.

Kyoya was already adding up the cost on his calculator (Adding on obvious extras like hiring the band, stage and lights, etc.) He pushed his glasses up his nose. "Hikaru, Kaoru, is your sister's band still together?"

They thought about it "It should be, but we haven't seen her since mother's birthday last year so we're not really sure. Why?" they said in usion,

"I was wondering if you could ask her to preform at this years summer dance." he said

Hikaru and Kaoru looked at each other and back at Kyoya "She should be fine with it."

"Wait... you mean Tanisuki, the girl who used to meet Kaoru and Hikaru after school?" asked Tamaki

"Yes,"

"Oooooh she's cute!" chimed Hunni, "Isn't she Mori?"

"... I guess so..."

***

Kaoru dialed Tanisuki's number and put it on speaker phone. After several moments of the dial tone there was a click of it being answered.

"Yo," said a girls voice

"Hey Tani!" they called in return

"Hey bruv! how you been?" when they spoke at the same time she didn't bother to seperate them as two people she just refered to them as one person.

"Fine."

"So you want a favour of me don't you? There has to be some reason for your call,"

"Yes, we were wondering if you're free in four weeks time?"

"Oooooh, I don't know, Its a bit short noticed... hold on... what day?"

"Saturday till sunday."

"... I might be able to squeeze you in somewhere... hold on isn't that the week of the summer dance? Kyoya wants me to preform doesn't he? and he wants some kind of discount cus' you're family? Am I right?"

"Spot on, so can you?

There was silence on the line for a while "... weeeeeeell... I'd have to speek to Lee but... I can work something out... tell Kyoya to call me tomorrow... what?" she called to someone on her end "okay guys I've got to go now, bye!" she hung up,

***Three weeks later***

Haruhi looked round the music room at the other hosts, who all had clients today. For some reason thursdays weren't very busy and even the more popular hosts (such as Tamaki and Hunni) only had a few bookings. There was a knock at the door, which was odd, people normally just came straight in. Tamaki excused himself from the two girls at his table and strolled over to the door, throwing it open.

"Hello and welcome to Ouran High School's..." he was cut off by a girl pushing past him, completely ignoring the fact that he was there.

"Tani!" shouted Hikaru and Kaoru, jumping up from their table and rushing over to hug her.

"Its been too god damned long." she said, wrapping her arms round both of them "Good lord you've grown!" she held the both at arms length. They were as tall as her.

This girl looked like a female version of the twins. Haruhi guessed that this was their older sister. "She doesn't look much older." Haruhi muttered to no one in particular.

"Actually Miss. Hitachiin is the came age a Mori, but her father didn't want her attending a school with boys so she recieved her education from the best private tutors money can buy." said Kyoya who was standing next to her.
