In the Lobelia Girl's Academy dormitory, a third year high school student was talking on her cellphone, "What do you mean he has a crush? My cute little Ritsu is too young to have a crush."

"Momoka-sama, he is a first year in high school." Tetsuya responded on the other end of the line. He had been a member of the Kasanoda-gumi for a year now, and it was his job to keep Momoka updated on her younger brother.

"Tell me about this girl," Momoka demanded. "How did they meet?"

"Well," Tetsuya paused. He was not sure if he wanted to explain that Ritsu's crush wasn't a girl.

"Well, what?" Momoka asked irritated. Like her brother, Momoka inherited red hair and a short temper from their mother.

"Well, he met Fujioka Haruhi in the Host Club."

"Her name is Haruhi?" She thought about the name, but then the rest of Tetsuya's sentence caught up to her. "Host Club?!"

"Yes, Fujioka-san is a member of the Host Club." He confirmed.

Flabbergasted, she asked, "Why is there a girl in the Host Club?"

"Um, Momoka-sama," Tetsuya started hesitantly, "Fujioka-san is a boy."

"WHAT?!" She yelled startled. "I mean I don't care if he likes a boy. I was just surprised." Momoka rambled.

"Momoka-sama, there is something else I should tell you." Tetsuya interrupted. "Ritsu-sama was the victim of bullying," He thought it would be simpler to call it bullying than to call it being targeted by a rival syndicate.

"Who would do something like that to my precious Ritsu?" Momoka asked with her eyes flashing. She had temporarily forgotten about Ritsu's crush.

"Don't worry. Ritsu-sama's big brother took care of the threat."

"Big brother?" Momoka questioned in a tone that terrified Tetsuya. "There is someone daring enough to take over my role as Ritsu's big sister?"

"No, Momoka-sama, no one wants to take over your role as sister. Ritsu-sama calls Morinozuka-san big brother." He tried and failed to cheer her up.

"Ritsu replaced me!" She wailed. Then, as if a fire had been lit behind her eyes, she promised, "Morinozuka, I will punish you for trying to usurp my position as Ritsu's older sister!"

An hour away in the Haninozuka residence, Takashi sneezed.

"Taka-chan, you aren't getting a cold, are you?" Honey asked his cousin worriedly.

"No," Mori replied simply.

#####

One Wednesday afternoon, one of the busiest days the Host Club had ever had according to Kyoya, the occupants of Music Room Number Three were disturbed unexpectedly. The double doors slammed open with enough ferocity that they smacked into the wall and knocked drywall onto the floor.

Some of the girls screamed in terror, and others cowered behind the furniture. The seven hosts stood quickly shielding their guests.

"Fear not, my princesses! I, the King of the Host Club, will be your knight in shining armor!" Tamaki exclaimed.

"More like a fool in aluminum foil," Haruhi mumbled.

"Oh, brother, I'm scared!" Kaoru whimpered.

Never failing to entertain the girls, Hikaru wrapped his arms around his brother and declared, "I'll protect you!"

Kyoya grabbed his phone and was quickly dialing his private police force.

Mori and Honey had dropped into fighting stances ready to demonstrate their abilities in order to protect the girls.

Their jaws dropped simultaneously, Mori included, when they got a good look at the intruder.

Standing at a whopping four foot nine inches, the intruder was wearing a Lobelia uniform with Medusa-like red hair and a glare that would make inanimate objects run for cover.

"Where is Morinozuka?" She asked.

Recovering from shock, the hosts closed their mouths and relaxed. Kyoya called off the cavalry and Tamaki began approaching the new princess.

"I'll only ask one more time: where is Morinozuka?"

"Here," Mori responded as he stepped in front of Honey.

Years of practice taught Momoka that people underestimated her because of her size. She would not make the same mistake when fighting Mori.

"Hi-yaw!" She yelled. Momoka took off running and jumped into the air.

As she sailed through the air, the lone male guest stepped towards both of them. When he realized just who it was that was jumping, he exclaimed, "Momo-nee?!"

"Ritsu!" Completely side-tracked, she fell to the ground a few feet from her target. When she stood up again, she launched herself at her little brother.

"Momo-nee?!" Tamaki and the twins yelled, "BossaNova, that's your sister?"

"Momo-nee, what are you doing here?" Kasanoda questioned.

"Ritsy, how could you?" She wailed into his chest, "How could you replace me with that giant over there?"

"Ritsy?" The twins giggled.

"Kasanoda-san, perhaps you could explain why you attempted to attack one of the hosts." Kyoya interrupted her tirade.

Honey bounced on the balls of his feet and leaned out from behind Mori. Mori hadn't moved, and Honey was getting concerned. The fact that confusion was visible on his face told Honey that Mori didn't have the slightest idea why the girl was angry with him.

"Momo-chan?" Honey asked stepping around Mori, who was still frozen. "Why are you mad at Taka-chan?"

Momoka let go of her brother feeling a little embarrassed about her outburst. She turned around trying to look innocent and lady-like. "Hello, I'm Kasanoda Momoka."

"I'm aware of that: Kasanoda Momoka, 17 years old, blood type AB. You're the second daughter of the Kasanoda family and older sister of Kasanoda Ritsu. Last I was informed, you were a Lobelia student. What I'm not aware of is what you are doing here?" Kyoya's glass glinted as he interrogated her.

"I'm here to see Ritsu!" Momoka grinned.

"Momo-nee, he wants to know why you were trying to attack Big Brother." Kasanoda explained unnecessarily.

At Big Brother, Momoka remembered her mission and her glare returned as she advanced on Mori again. "I challenge you, Morinozuka, to a fight."

The other guests and hosts had been watching Momoka intently. When she issued her challenge, they, in unison, turned towards Mori.

"Huh," was Mori's intelligent response.

"I challenge you for the right to be Ritsy's big sister." Momoka stopped inches away from Mori.

"What?" Mori blinked a couple of times and the look of confusion deepened. He resisted the urge to bend down to her level or pick her up to his. He didn't get the feeling she would appreciate that.

"Name your terms for the battle," Momoka continued.

Mori's brain turned off and turned back on again in an attempt to unfreeze.

"I apologize, my princesses, but I believe we will have to end our day early." Tamaki said ushering the guests out of the room.

"Any day now, giant-san."

"Momo-nee, you can't fight Big Brother." Kasanoda answered instead of Mori.

"I can and I will. You replaced me with this, this skyscraper. I have to defend my position as your Big Sister."

"I think she has," Kaoru started.

"A brother complex," Hikaru finished.

"You guys are one to talk," Haruhi said rolling her eyes.

Once all of the guests minus Kasanoda had left and the doors had been closed, Tamaki approached Momoka. "Might I suggest we all calm down and come to a reasonable decision?" He asked and Haruhi snorted at the thought of Tamaki coming up with a 'reasonable decision'.

"The only reasonable decision is for him to fight me."

"I don't want to fight you." Mori finally said more than one word.

"You don't get a choice," she responded, "A challenge, once issued, cannot be taken back. You must fight me. Now name your terms."

"Rock, Paper, Scissors?" Haruhi suggested.

Mori began nodding enthusiastically, "Yes."

Momoka almost fell over in surprise, "Fine. On the count of three."

"One," The twins grabbed popcorn.

"Two," Kyoya started scribbling in his notebook.

"Three!"

Mori displayed rock, and Momoka played paper.

"I win! I get to be Ritsu's Big Sister again." Momoka started doing a victory dance.

"Um, Momo-nee, you were always my big sister." Kasanoda said looking at his sister.

"Yep, and I'm the only one! Take that giant-san!" She said sticking out her tongue at Mori.

"What about Kaede-nee?" He reminded her of the oldest Kasanoda sibling.

"She doesn't count." Momoka said dismissively.

"Well, that was anticlimactic." Hikaru said.

"Yeah, I wanted to see the pipsqueak fight Mori-sempai." Kaoru added.

"Pipsqueak?" Momoka turned on Kaoru, "Do you want to go? Well, do you?"

Kaoru sweat dropped, "No, no, I don't. We are just going to go over here." He dragged his twin into a side-room. Tamaki, Kyoya, and Haruhi followed the twins out.

Returning to her angelic appearance, Momoka turned towards the remaining hosts. "Now, that all of that is out of the way. It's a pleasure to meet you Morinozuka-san. Thank you for taking care of Ritsu for me."
