Summary : Amu is Ikuto's younger sister while Ikuto is 3 years older than her. Ikuto has always been in love with her but couldn't tell her knowing she doesn't feel the same thing. A new school they go to would probably lead to fanboys, fangirls, stalkers and mayhem. What is Ikuto to do?

Kumi : Yo my readers!

Ikuto : We're here for another story and it involves as Amu-koi being my sister.

Amu : Yay no Ikuto being my lover!

Kumi : *sigh* Amu, Amu, Amu... In the end, Ikuto would always be your lover *smirks*

Ikuto : *smirks*

Amu : *pouts*

Kumi : I know that I still have other stories to update and I will! But heck the idea of brother/sister love is too tempting for me :3

Amu : Wait what about Utau?

Kumi : She's your (you and Ikuto's) cousin but is not in love with Ikuto. Now neko, do the disclaimer!

Ikuto : Kumi does not own Shugo Chara, if she did, Amu wouldn't be denying her feelings for me. ;)

~Chapter 1 : New Boarding School~

Ikuto was in his room, packing up his stuff for his new school. To be honest, he wasn't really sure going to an actual school instead of being home schooled was a good idea. Sure he could make new friends and get a girlfriend. But no, he doesn't want a girlfriend. The reason he doesn't want a girlfriend is because he was in love with his sister, Hinamori Amu.

Her last name isn't the same as his because his parents decided it. His sister is one year younger than him and she has natural and unique hair he has ever seen. It was bubblegum pink and it at first shocked his parents because they both didn't have pink hair nor could they have any relatives that had pink hair so it was a mystery. She had cute honey orbs that were mesmerizing as much as his and it showed pure innocence.

When he was packing, he could still remember what had happened a few minutes ago with the family.

-Flashback-

"Why did you need us for Otou-san?" Ikuto asked in an irritated tone. He was having so much fun teasing Amu just now in her room until Aruto had called them down.

"You two are going to Seiyo High's boarding school." he simply stated.

Amu was beyond shock and it showed while Ikuto was keeping a blank face but inside he was just as shocked as her.

"What do you mean Otou-san?" Amu asked.

"Like I said my dear Amu, you and Ikuto are going to a boarding school." Aruto smiled at her.

"But why?" Ikuto asked with a still irritated tone. Amu knew well that his brother was getting irritated.

Aruto sighed, "We can't have you two in the house always and not have any friends. It's good to get more experienced in our world and you two have been homeschooled for too long."

They have always been homeschooled since Amu turned 5 years old.

"I have friends already and Amu has Utau to play with." And me he thought.

"I know Ikuto but it might be fun for both of you to try. You can come home in the school holidays and weekends if you want." Aruto said.

Ikuto was pondering if they should be home only during school holidays or when it was weekends. He looked over at Amu who was also thinking the same thing as him. Then an idea came in his head.

"Do I get the same room as Amu?" he asked and Amu quickly looked up at her brother and gave him a glare which he knew of course but ignored it.

Aruto nodded his head, "So agree yes?"

Ikuto nodded his head and looked over at Amu who was still glaring at him. As much as Ikuto would like to smirk at her, he couldn't let anyone know him too well. Amu looked back at Aruto, she sighed then nodded her head.

-End of flashback-

As long as Amu is in the same room as him and not some other students, he's as good to go.

"This could be fun." He said and smirked.

In Amu's room,

She knew her brother was not like any other older brothers in the world. Sure older brothers do tease their younger sisters but the way Ikuto teases her is different. When he teases her, she would stutter and blush like crazy. She has always found her brother perverted and annoying and sometimes could be labeled as a midnight blue cat.

Anyways she was just packing up her bags and thought over what it would be like in a real school.

Would she make friends? Would she get bullied? Would she have a boyfriend?

She blushed when she thought she could get a boyfriend. She shooked her head and said to herself, I'm not that pretty. Heck I bet there is a lot of other prettier girls than me.

To Amu she was just an average girl who had pink hair. To others, she's a hottie! Which includes her brother thinking that way too. Her hair reached below her shoulders and she mostly keeps partial of her hair up in an X clip.

She thought back to what Ikuto said about them sharing a room. It's not like they had when they were younger but she knew how perverted her brother is to her so she had to make sure to stash her underwear safely away from him.

Next Day, (This is Sunday)

"Welcome to Seiyo High, I'm Yukari Sanjo and I'll be giving you two a short tour of the school." She said with a fake smile while adjusting her glasses.

The two siblings nodded and followed Ms. Sanjo towards their dorm room.

"This is your room and your keys. Usually it would be boys with boys and girls with girls instead of this." She said.

Ikuto and Amu both took their keys and Ikuto smirked, "I'm just protecting my sister."

"More like gonna rape your sister." Amu muttered.

"I'm sorry, what?" Ms. Sanjo asked Amu.

"Nothing." Amu said with her oh-so sparkly smile that always hypnotize people and it worked really well with Ms. Sanjo. I'm so gonna work my charm off. she thought to herself.

Ikuto never got trapped into Amu's 'spell'. He's been through it many times when he was trying to tease her to take control over it.

Ms. Sanjo unlocked the door and walked inside followed by the two. They looked around and overall, it was okay. There were two beds so the two siblings don't have to share which made Amu relieved while making Ikuto disappointed.

They decided to put their stuff inside the dorm first then take the tour.

Later on,

After the tour, the two headed back towards their dorm and unpacked their stuff.

"Okay Ikuto, I take the one closer to the window." Amu said pointing towards the bed that was close to the window.

Ikuto shooked his head and smirked. "We're going to share one."

Amu's jaw dropped, "What the heck do you mean?! There are two beds and only one can fit one person."

Ikuto clicked his tongue and walked towards the other bed and pushed it until it reached the other bed so it made a king size bed. Amu smacked her forehead. Of course the pervert knows how to solve problems like this. Well this wasn't a problem at first anyways.

She sighed and took out her toiletries pouch along with Ikuto's and went to the bathroom to set up the stuff.

She was disappointed that they didn't have a bath tub and only have two shower stalls.

After they finished unpacking and everything, they sat down on the sofa that was facing the TV and decided to watch a movie. Amu was making popcorn in the small kitchen while Ikuto was choosing the movie.

Step Up Revolution or Breaking Dawn? He thought to himself. He heard Amu walk towards the living room and sat down with the popcorn on her lap. She looked at Ikuto and he looked at her.

"What movie?" She asked him.

"You decide, Step Up Revolution or Breaking Dawn?" Ikuto asked her. She pointed at Step Up Revolution and he nodded and played the movie. After he did that, he got up from the floor and walked towards Amu and sat down next to her.

As the screen kept on playing, Ikuto was getting bored and looked at Amu who also looked bored. He decided to have some fun by pulling her from her waist so she was on topd of him and on his lap while he buried his face in her hair. Amu was blushing as always and tried to get out of his grip but he tightened it.

"I-ikuto let me go!" She demanded him.

She could feel Ikuto's breath and it tickled her which wasn't comfortable. "No."

She tried again to get out and again, again, again and finally... Again. But no, he wouldn't loosen his grip. She huffed and gave up and just leaned back on Ikuto's chest and he smirked in her hair as a victory.

Amu couldn't help but feel like this is what a couple would do when they would watch a movie. She blushed at the thought of them being a couple. There was no way she could think of Ikuto like that!

"Thinking of something, eh Amu?" Ikuto teased and his breath again tickled her neck which made her shiver. He chuckled.

Let go of me already you neko pervert!

"No, I won't let go because I love cuddling my little sis-" Then Ikuto had an idea and it would surely make her blush beet red. "Amu-koi" And he had been rewarded with her blush.

"D-don't call m-me that!" She yelled at him. "I'm you're sister so you have to call me your imouto!"

Ikuto shooked his head. "Amu-koi sounds better" and he smirked.

"Isn't t-that f-for someone who w-would call their girlfriend?"

Ikuto thought about Amu being his girlfriend, he would have definitely made her his if they weren't siblings and blood related at that. Actually when the two go to amusement parks together, people think they were a couple and a cute one at that.

"Then be my girlfriend." He muffled in her hair.

Amu froze, she could definitely hear him well enough to know what he said. "What?"

Ikuto shooked his head, "Nothing."

Amu shrugged it off and they both continued watching the movie until Ikuto fell asleep with Amu in his arms. Amu was still awake but she didn't move out of Ikuto's grip because she was comfortable. Even the pervert has his good times being her good older brother that she would want to hang out with him.

Next day,

Amu looked at the time and it red '7:00 AM'. School starts in two hours but Ikuto would wake up at 7:30 so to avoid having to shower with him at her side, she decided to take a shower and brush her teeth.

After she took her shower, she wrapped her figure in a towel and walked out of the bathroom only to slam into a wall that was soft. Huh?

"Walls aren't soft." Amu said loudly and heard a chuckle from above. She looked up and saw Ikuto looking down at her. She moved back and held her towel up because it was about to fall.

Ikuto smirked and looked up and down at her. He knows it's wrong to check out his sister but how could he not? A hot girl in a bathroom only wrapped in a towel that came down until her knees.

Amu knew he was gonna tease her but instead he shrugged and walked inside and started brushing his teeth. She was confused for a moment then walked out of the bathroom and closed it behind her.

Ikuto sighed in relief, apparently he was also turned on and if she ever found out, he would be labeled as the most disgusting brother she ever had.

Homeroom,

Everyone was busy talking and then suddenly the door was opened and three figures walked inside. The first figure was of course the teacher, followed by Ikuto and Amu. (P.S they have a mixed age classes around 13 to 16. Main age is 15.)

"Okay students, I'd like to introduce to you two new students. Please introduce yourselves starting with Tsukiyomi-san."

Ikuto faced towards the crowd of people and noticed all of the girls had hearts in their eyes and the boys were also but not at him, more like Amu. He put his hands in his pants pockets and clenched his fists.

"Tsukiyomi Ikuto, age 16. I'm not interested in anyone except for one special girl." He smirked while looking down and the girls were about to faint at the presence of a god.

It was Amu's turn and she was nervous. She never had to do this, okay will when her parents got them new teachers she had to but that was only a person when this was a bunch of people.

"Hinamori Amu, age 13. I'm Ikuto's," Before she could continue, she noticed the girls glaring at her and the boys with full of hope, hoping she wasn't Ikuto's girlfriend. Amu narrowed her eyes at the girls and continued, "You know what? Forget it. Just tell me where I'm sitting." She said with her 'Cool n Spicy' facade.

"Okay, the two of you can sit at the back row near window." The teacher said. Ikuto nodded and pulled Amu's arm which caused her to stumble a little.

As they were making their way towards their table, a redhead girl put out her hand in front of Ikuto and gave him a piece of paper. She mouthed 'Call me' and winked at him. Ikuto rolled his eyes and ignored the paper and just sat down with Amu on his left.

To Amu, when she first saw the girl, she knew that she would be very irritating and annoying so she decided against being friends with her.

At lunch break,

Amu got out of her chair and made her way to the cafeteria. Ikuto wasn't in the same class as her but she guessed as much he would be there.

She was alone in the hallway until she got stopped by 5 figures and one of them was the redheaded girl. She pointed an accusing finger at Amu and glared at her.

"Hinamori Amu, don't you dare try to get near to Tsukiyomi-san! I, Yamabuki Saaya is the only one who could win his heart!" she said.

Amu was gonna laugh her ass off and she did. After she had calmed down she smirked at the girl in front of her, "Get near my brother?! I'm already part of his family."

The girls were shocked. "You look nothing like his sister!" Saaya said.

Amu rolled her eyes and was about speak until she felt someone behind her and already guessed who it was. "Everything okay, Amu?" a deep husky voice asked her.

The girls were about the faint at the presence of the figure except for Amu. She sighed and said while glaring at Saaya. "As always big brother."

Ikuto tsk-ed, "Don't call me that. I told you to not when you were 5 and only to call me Ikuto." he bent down towards her ear and added, "Although now you have choices of Ikuto-kun, Ikuto-koi or Ikuto-sama."

Amu was flustered and decided to punch her brother but failed. She was gonna loose control but decided against it, instead she was gonna show the girls in front of her that Ikuto was her brother.

"Ikuto~" She started whining. "Tell these... girls that I'm your sister." She pointed her thumb at them while she faced her brother.

Ikuto looked up from Amu to Saaya then back to Amu. He shooked his head and smirked. Amu lifted an eyebrow as Ikuto advanced to hang his arm on her shoulder. He looked over at Saaya and she blushed.

"This is my.. girlfriend." He said while smirking at Amu. He bent down and kissed her cheek.

Amu and the other girls froze on the spot. The first one to recover was Amu and after she had, she had immediately screamed, "GIRLFRIEND?! IKUTO WHAT THE HECK!?"
