Summary: Tsukiyomi Ikuto and Hinamori Amu have never met before. What happens when Ikuto's dad and Amu's mom decide to get married? What happens when Ikuto starts to have feelings for his new step-sister?

Chapter 1

"You're getting married?" Amu asked, horrified.

"Honey, he's really nice and I think we'll have a really nice life together. He even has a son, a few years older than you. I haven't met him but Aruto talks so fondly of him and—"

"But Mom, I don't want to move!" Amu interjected. "I don't want to move in with strangers!"

"Honey, they're aren't strange…"

"I've never even met him, not to mention his son that I've never heard about 'til now!" Amu exclaimed.

"Sweetie, I showed you pictures of Aruto. Isn't he handsome? And he's so kind and sweet and romantic—"

"Mom, I thought it was just harmless dating! Anyway Mom, whenever he brought you home I would always be asleep so I never got to meet him in person! And now you're getting married!"

Mrs. Hinamori looked at her daughter with a pained face. "Honey… I really love him. I'm happy with him. Does the idea of marriage make you feel that… unhappy?"

Amu felt guilt flood her. "No, Mom, just… I'm fine with it, okay? Don't be sad. I'll be fine." Mrs. Hinamori smiled and gave her daughter a hug.

"Oh Honey! This is going to be so much fun! Honey, I know this is the right thing to do! I can feel it!"

Amu sighed in her mother's embrace. She knew she was being out of character. She would never show these kinds of feelings with her "You're probably right…"

"You're getting married?" Ikuto asked, trying to hide his shock. "To that woman you're dating?"

"Yes, Ikuto. We decided it yesterday on our movie date," Aruto said with a smile.

Ikuto shrugged. "If you're sure."

"I am sure, Ikuto. She makes me happy! Oh, and she has a daughter a little younger than you are."

"A daughter? You've never told me that she had a daughter."

"Well, we never expected things to get this far," Mr. Tsukiyomi said with a smile. "I know that all of this will turn out great, Ikuto!"

"Sure, Dad."

They were going to have the wedding in the front yard of the Tsukiyomi house. Aruto was a famous violinist and was really rich as well and lived in a mansion. Mrs. Hinamori was driving Amu to his house so that they could all meet formally. They were going to start living in their house. The engagement party was going to be held a few days later.

When they got there, they saw Mr. Tsukiyomi on the stoop of his house.

"Midori!" he called out, stepping down the steps and jogging to the car. Mrs. Hinamori stepped out of the car and embraced her fiancé, giving him a kiss. Amu sighed and opened the car door and got out.

"Oh, Aruto, this is my daughter, Amu. Amu, this is Aruto!" Midori said with a smile.

"Hello, Amu-chan!" he said with a warm smile. "Nice to finally meet you. I've heard so many good things about you!"

"It's nice to meet you too," Amu said politely, shaking his hand. He looked nice enough, with dark hair and a bright smile. That she had seen in the photos, but in person, he seemed even nicer.

"Ikuto's out with his friends right now, I apologize for him not meeting you two in. Where's the moving truck?" Aruto asked with a smile.

"It was behind us—"

Just in time, the truck was seen turning the corner onto the pathway.

It stopped and the driver stepped out. "Oh, Midori! This place is wonderful!"

"Thank you, Macy-chan," Midori said. "Oh, and thank you for driving the truck for me! Amu didn't get her license yet and I didn't know what to do since I ordered the U-Haul truck without even thinking about it and already paid and everything!"

"No problem, Midori!" Macy said with a wide smile. Macy was one of Midori's closest friends from work. She wore bright red lipstick and had her light strawberry-blonde hair out and in curls. She was definitely the energetic type. "Now, just help me unpack this stuff and then I'll head back—Oh, unless you need me to help unpack? Oh, and hello Tsukiyomi-san! Nice seeing you again!"

"Nice seeing you, too, Smith-san. But, no, we don't need your help, thank you, though, for the offer," Aruto said with a smile.

"Well, alrighty then!" She turned towards the truck brfore whipping her head back again. "Oh, Amu-chan! It's so nice to see you again, Sweetie!"

"It's nice to see you too, Macy-san," Amu said with a nod and a forced smile.

Soon, everything was out of the back of the truck and Macy was waving her hand out the window as she sped off.

"She sure is… full of energy," Aruto laughed with a smile.

"Yes she is," Midori smiled back. "She really is a good friend once you get to know her."

"Oh, I believe you," Aruto said, leaning in to kiss his soon-to-be wife.

Amu turned her head quickly. Gross! she thought, squeezing her eyes shut. She then grabbed her suitcases and headed to the house after her mother and her soon-to-be stepfather.

The place was ginormous. Even bigger on the outside than in the inside.

"What about this?" Aruto suggested. "Amu-chan, why don't you go upstairs and find an empty bedroom? You can pick whichever one you want that's empty, Honey. Then you can get yourself settled in and meet your mother and me in the kitchen. We can have a tour of the house after that. Oh, and you could also pick a guest room if you want, although we do have some totally empty rooms that are there for your pick as well."

"Okay," Amu nodded.

"Oh, and Honey, don't forget your boxes are here too, okay?" Midori added.

"Yes, Mom."

Amu decided to first take her suitcases and then bring up her boxes and other furniture.

Any room huh? Amu walked through the hallway of the second floor. Why not see what rooms she had in total before making her final decision?

Most of the empty bedrooms that she found where big with a nice view. After looking at all of the rooms on the second floor, she went up to the third. There were tons of nice rooms in her mind right now. How was she going to decide? And how many damn floors were there in this house? She started roaming around the fourth floor. She reached the last door in the hallway and opened it. This was not empty. Nor was it a guest room.

This room was large and painted a dark blue. It had a large bed with black covers and dark blue pillows. There was a plasma TV in the room and a black leather couch. The walls were decorated with posters of famous musicians, pictures of unknown people to her, and different artwork. A desk was placed in the room and it was littered with papers and a large, slick laptop. Two sliding glass door led to a balcony.

She saw a bedside table next to the bed and on it was an alarm clock and a picture frame. She could make out the faint outline of a woman. She dropped her things and walked into the room without thinking and looked at the picture. It was of a woman with long blond hair and a bright smile. She was holding a baby in her hands, but the baby was asleep and bundled in covers but Amu could still see dark blue hair.

Amu looked around the room. It was nice. Who could've…? She mentally slapped herself. Of course. This must've been his son's room. She started feeling uncomfortable being in his room, and turned around to the doorway when she heard a voice behind her.

"Why the hell are you in here?" the voice said. Amu's eyes widened. The sound was coming from behind her, not from the doorway that she was facing. Behind. Her. Amu turned around. The balcony door was opened and next to it stood a tall teenager who looked no more than five years older than her. He had dark blue hair and bright blue eyes. He was wearing a black t-shirt and dark ripped jeans. How did he get in there? It couldn't have been from the balcony, could it?

Amu stared at him.

"You know, it's rude to stare," the guy said with a smirk.

"Shut up! I wasn't staring!" she yelled back. "Who are you? How did you get in here?"

"You know, I should be asking the questions. You are in my house and in my room."

"You're… room… You're… house…," Amu felt a deep blush form on her face. Dammit. Dammit. Dammit.

"Yep. So, you are?" the boy said, walking towards her and smirking at her. He leaned in towards her. "And is a girl like you in my room?" A girl… like… Amu blushed violently and pushed him back.

"I'm Hinamori Amu!" she yelled. "My mom's Hinamori Midori and she's getting married to Tsukiyomi Aruto!"

The boy looked at her, probably processing it all in. Then he smiled. "Ah, so you're her daughter? Well, I guess we finally meet, Amu. I'm Ikuto, Aruto's kid."

Amu still felt the redness on her face. "Don't you have any sense? Don't call me Amu!"

He blinked. "That's your name isn't it?"

Amu blushed. "Well, yeah! But don't just call me Amu! If you had any respect you'd use a honorific!"

He laughed. "You're going to be my stepsister, why should I use an honorific?"

"Because it what you have to do," Amu said through gritted teeth. "At least until after the marriage."

Ikuto sighed and Amu smiled. She had won. "Fine. I'll use an honorific."

"Good."

"So, Amu-koi, why are you in my room again?" Amu's face flushed.

"Don't call me Amu-koi!" Amu yelled.

Ikuto laughed. "You're choice, Amu-koi. I could call you Amu-koi or Amu. What will it be?" Amu fumed and Ikuto leaned in and whispered in her ear, "I'll understand if you want me to use the honorific."

"No!" Amu yelled, pushing him away. "Call me Amu-san or at the very least Amu-chan—"

"No can do," Ikuto said, lying down on his bed, his arms behind his head.

"Fine," Amu said through gritted teeth. "Amu, then."

"Deal, as long as you call me 'Ikuto.'"

"No!"

"But, Amu-koi—"

"Fine! Ikuto, there, I called you Ikuto!"

"You should learn something about me, Sis," Ikuto said, standing up from his bed and moving towards her. Amu stepped back and found the wall behind her. He put one hand onto the wall beside her and leaned close. He smiled and leaned his face towards her. "I always get my way," he breathed. Amu felt his warm breath on his face. He was… really… close.. Her face was instantly red again. He then smirked and stepped back. "Oh, and you never told me why you were in my room, Amu."

Amu glared at him, but her face was still bright red. "I… was looking for a room." He looked at her. "You know, to be my room?"

He smirked. "So, you saw this room was occupied. Why'd you come in?"

"I saw the picture of your mom." Amu saw Ikuto's jaw tighten, and his smirk vanished. "I'm going to go find a room…" Amu moved towards the door and was about to turn it when she saw Ikuto smile behind her.

"Don't go too far Sissy," he said, lying down on his bed once more.

Amu decided on a bedroom on the second floor that had a nice view, a window seat, and a large balcony. The room was fairly large and didn't have any furniture except for a bed that was made and had a dull colored floral pattern. She thanked God that she had brought her own bedding.

She placed her suitcases into the bare room and went downstairs. She grabbed the boxes that had Amu written on it and placed it into her room. Then went back to grab pieces of furniture that she could carry by herself easily up the stairs, like her lamp, her beanbag, her small bedside table, cushions from her chair that she would need help carrying, and a few rugs.

She started unpacking the clothes that she could hang up in the closet and then started taking off the sheets and bedding on the bed and replacing it with her own. The bed was nice and comfortable and was also fairly large. She placed her own pillows onto the bed, but left the old ones since they were comfy, it was just their cases that needed to be changed.

She placed her bedside table next to the bed and placed on it her own alarm clock the book that she was in the progress of reading. She then reached into the box and brought out her pictures. She had brought her album and her frames. She was going to decorate her bedside table, dresser, shelves, and walls with them. She sighed and opened up her album. It wasn't going to be like she would never see her friends again… the Tsukiyomi house wasn't that far away. It was just more suburban and she lived more city. She would be going to a different school. The same as Ikuto. Great, Amu thought, rolling her eyes.

At least he was a senior and she was a freshman, although it wouldn't be a surprise if he was held back. She smiled at the insult she mentally thought for him.

She flipped through the album until she found the right picture. There she was with her best friends, Yaya, Rima, and Kukai. They had been together forever. Yaya had orange hair and wore a giant smile, Rima had a small smile and wore her blonde, wavy hair out like always, and Kukai smiled at the camera, giving it a big thumbs up, his green eyes gleaming with happiness. She stood in the middle of Yaya and Rima, smiling happily, not knowing that she would be moving away from them. It didn't help that they had all lived really close to each other. And now… they were going to different schools….

They reassured her that even though they were going to still be the best of friends and visit as much as they could, but the house was more or less thirty minutes away, driving, when before, it didn't take longer than five, walking, to get to the other's house.

She took out her phone and looked at it, longing to text them, to hear from them again, even though she had just seen them before the move. Sure, maybe she was over-reacting. But… still…

Amu walked down the stairs to get ask her mom or Aruto to help her with her other furniture when she ran into Ikuto. Again.

"Hey, Sis. Where you going?" he asked with a sly smile.

"I'm going to get my mom or your dad to help me take my furniture up to my room. Is that a problem?"

"No, no. But why don't I help you?" Ikuto said, placing his hand on top of the dresser.

"Why would you want to do that?" Amu asked coolly.

"Think of it as sibling bonding," Ikuto explained with a smile.

"Fine, just don't drop anything."

"Me? Have you looked at your arms? I don't think you got much muscle, Sweetheart. Or much of anything. Except maybe chubbiness."

"I am not chubby!" Amu yelled.

"Tell yourself what you want," Ikuto said with a smile. "We all know what's true."

"Y-you-!" Amu fumed.

Ikuto picked up one side of the dresser. "Hey, Amu? I think you should pick up the other side, just so we can get it up. Well, maybe it would be better if you didn't help…"

"YOU JERK!" Amu exclaimed.

Ikuto smiled innocently. "Let's go."

Surprisingly, after only ten minutes, all of her furniture was up the stairs and it the spot that she wanted it in and she was almost finished unpacking when Ikuto walked back into her room.

"Hey, Amu," he said, taking a look around the room before flopping down onto her bed and stretching out.

"Get off, idiot!" Amu yelled, placing a picture of her and Rima on her dresser.

"Fine, fine. I didn't know you wanted me by your side that badly." Ikuto smirked as he got off the bed and walked over to her side.

"You—I didn't mean that!"

"Yeah, yeah. Hey, you going to tell me who all these people are, or do you want me to guess?"

"Sure, why don't you guess?" Amu said coolly. Ikuto shrugged.

"These are you're two best friend," he said pointing at a picture of Amu with Yaya and Rima. He looked at a picture of Kukai and Amu together and he looked like he was suppressing a laugh. "And this is your boyfriend?"

"No!" Amu exclaimed, face red. "That another one of my best friends!" It shouldn't have surprised her. Lots of people one time or another think that Kukai and she are a couple, but that is because of how close they are. They've known each other practically since birth, even longer than either of them knowing Rima or Yaya. He helped her out a lot, with giving her advice about life and how to deal with it. You'd never expect it from someone like him, since he was mostly always energetic and had a great sense of humor. You'd never expect him to be able to give great advice like that. But he knew when a situation is meant to be serious and when it wasn't.

"Oh, just a friend?" Ikuto teased, raising an eyebrow.

"I'm serious, Ikuto, he's just a friend."

"Is he one of these two's boyfriend?"

"No! We are all friends. Best friends."

"Whatever," Ikuto said, looking around. He saw a picture that was nailed to the wall. It was of a goofy looking guy with light brown hair and he was taking a picture of a bird. Ikuto's expression changed. "Who's this?"

"That's my dad," Amu said casually. She hadn't exactly gotten over his death, but she wasn't going to stutter or hesitate anymore when saying that he was dead. It was simply fact and she moved on past that.

"Something happen to him?" Ikuto asked, examining the picture.

"Yeah. He died. Six years ago. He got in the middle of a shooting." Ikuto looked at her, probably trying to see if she was going to cry. But no. She had said this story too many times to cry again.

"My mom's dead too. Twelve years ago. Cancer," Ikuto said.

"I'm sorry," Amu said. He shrugged. She noticed that he was probably the only person who didn't apologize to her, after hearing about her father's death.

Ikuto looked back at her and smiled. "So, Amu. What are you going to do now, since you unpacked and stuff?"

"I'm going to go down and your dad is going to show me and my mom a tour of the house."

Ikuto smirked. "Why don't you let me take you on a tour?"

"How about no?" Amu nodded towards him and then rushed out of the room.

Ikuto sighed. It was funny, getting to tease her as much as he wanted. He lay back on her bed and looked back up at the ceiling. So, this was his soon-to-be stepsister. Well, she wasn't too bad. The pink hair had surprised him a bit. He instantly wondered what her real hair color was, but after seeing her mom's hair and now her dad's, he knew it was some shade of brown. Probably light brown.

She was actually pretty cute… for his soon-to-be stepsister anyway. Not like anything more than that. But then why… did his heart race when he saw her in his room? When he accidentally-on-purpose bumped into her on the staircase? Why had he been hoping really hard that the orange haired boy in the picture with her wasn't her boyfriend? Ikuto rolled onto his side and scowled. He hated not figuring this out right away. Whatever… it's not like anything would happen between them. She was going to be his sister, after all. No, not sister. Step-sister.
