Disclaimer: I do not own Ouran High School Host Club in any way, shape, or form.

Closing the door to the last library in the school, I sighed. Haruhi wasn't in there, either. Where the heck is that girl?, I thought as I walked through the quiet halls of Ouran Academy. The libraries were full and too loud, and I know she must be looking for a place to study.. But we need to head home already, or dad is going to throw a fit... I sighed and continued walking then paused when I ended up in front of music room 3. I stared at the door for a moment. It looks like an abandoned music room, but I already know better than to believe that... But did Haruhi...? I stood there for another moment, deliberating on whether I should go in or not. With a sigh then a deep breath, I warily pushed the door open and was met with rose petals flowing through the door, then I saw the Host Club.

"What do you know," one of the red-haired twins started.

"We finally got a girl instead of a boy.~", the other twin finished.

"She must be a commoner, too, though, she isn't wearing a school uniform, either." Hikaru said.

Instead of a boy...? Well, Haruhi did dress like one today on accident... "For your information, I could easily afford my own uniform, but there's no way in hell I'd be caught dead in those hideous dresses!"Then I heard a gasp and the tall blonde haired boy with purple-ish eyes popped up in front of my face, causing me to jump back a step. "Oh, Nica~! You finally accepted my request to come and check out my Host Club~!"

"Not even in your dreams, Tamaki. I'm here looking for someone." I replied, giving the blonde haired prince a slightly annoyed look.

"Ah, yes, I take it you're looking for Haruhi then, Nica?", asked the tall, dark haired boy with glasses who happened to be none other than Kyoya Ootori. I nodded, "Yes, I am, I suppose that means Haruhi really did stumble upon this place?"

"That's correct, Haruhi was here and broke a very expensive vase, so will be working it off here as a host until it is paid off."

I sighed. Classic Haruhi, being the clumsy mess she is, getting in trouble with men like this. "Well, how much longer will this take today? We need to go home before our dad starts to freak out."

"Of course. Hikaru, Kaoru, go and fetch Haruhi for us."

"Right!", the twins said in unison before running off. I gasped as my arm was suddenly glomped and I was spun around a few times before regaining my balance and focusing on the small blonde-haired boy. "Nica-chan! Do you wanna come have some cake with me and Usa-chan while you wait!?" I blinked then smiled kindly. "Sure, I would love to, Hunny-Senpai..", I replied and then was dragged off to a small table filled with all kinds of cakes and sat down with the senior and watched with a smile as he talked animatedly while stuffing his face with cake.

~Meanwhile...~

Tamaki continued to stare as Nica sat eating cake and chatting with Hunny. "Mm... Kyoya, is it just me, or does she look a lot like our Haruhi?" Kyoya glanced up from his laptop and over at the 'King', as he liked to be called, before pushing up his glasses and continuing to work. "I would assume so, seeing as she is Haruhi's sister." The blonde's eyes widened as he swung around to stare at the Shadow King. "She's Haruhi's sister!? I didn't even know Haruhi had a sister!"

"Honestly, Tamaki, I'm shocked you haven't noticed the resemblance sooner." At this, Tamaki went into his little depressed corner and poked at a mushroom.

~Back to Nica and Hunny~

I was listening to Hunny-Senpai's story about some dream he had when a tall and mysterious looking boy walked up and sat down next to him. Upon seeing the other boy, Hunny brightened up even more, if that's even possible, and proceeded to hope onto the taller boys back. "Takashi! Look look, Nica came to visit the Host Club like Tama-chan has been talking about getting her to do!"

"Hm.", was the only reply from Mori-Senpai and he nodded a hello to me. I smiled at the two, "So, is practice still on for tomorrow?"

"Of course, Nica-chan! The dojo is always open for you!", Hunny replied happily.

I smiled again. "Great, I'll see you guys then. I have to grab Haruhi and hurry home." As if on cue, the twins burst back into the room, dragging a disgruntled brunette between them. "Here he is~!", they yelled in unison, unceremoniously dropping Haruhi onto the floor.

"Ouch! Hey, you didn't have to drag me off like that, ya know!" I rolled my eyes and helped her up, dragging her toward the door while doing so. "You can complain later! Come on, we're gonna be late and not have time to fix dinner tonight!"

"Alright, alright, I'm coming!"

The Host Club watched as the two girls ran off together. The twins looked over at Kyoya, who was currently writing in his black notebook. "So, Kyoya-Senpai,", Hikaru said.

"Who was that girl and why was she looking for Haruhi?", Kaoru finished.

Kyoya glanced over at the twins. "That," he said, while pushing up his glasses again. "Would be Haruhi's twin sister, Nica, who happens to have managed to skip a grade upon entering Ouran so is in my and Tamaki's classes." The whole club just stared at him in shock, save for Mori and Hunny.

"Haruhi has a twin?!", the twins and Tamaki echoed in harmony.

"Wait, so... HARUHI IS A GIRL!?", Tamaki screeched.

Kyoya sighed. "Honestly Tamaki, it took you this long to figure that out? You may be more hopeless than I originally thought."

Hunny looked down at them from his perch on Mori's shoulders. "Nica-chan comes by the dojo all the time to train with us! She's actually really good!"

The twins looked up at Hunny. "Oh really?", Hikaru asked. Kaoru looked over at Kyoya while Hunny and Hikaru talked about how a girl of that stature be good at martial arts. "Kyoya-Senpai, how was it she was able to skip a grade when Haruhi didn't?"

"Hm? Oh, that would be because she's taking the more advanced drama class, so they decided to put her into a higher class to avoid conflicts when making her schedule."

"It's still kinda hard to believe that she's Haruhi's twin. I guess that's what Haruhi must look like if she actually ever dressed like a girl and grew her hair out..."

"Hn. I have a feeling we may be seeing a lot more of Nica if Haruhi stays in the Host Club."
