Chapter 1

Siblings?!

(Amu's POV)

"Amu-chan..." My mother said my name quietly, causing me to look up from the plate of food I had been staring at. "What is it mama?" I said as lifelessly as I had for the past five months. "Amu-chan, you know that it's been hard these five months... being how Ami and papa have been gone..." She trailed off, and I nodded, reluctantly. "Yes, I know mama..." I said, somehow urging her on. "Well... I found a new husband Amu-chan..." She finished, and I felt all the color that had been gone, return in half a heartbeat. "WHAT?!"

Walking to school

"Erg! I can't belive she is getting married to some rich guy!" I shrieked, and all my charas covered their ears. "Calm down Amu-chan!" Ran cheered, "Yes, you might hurt yourself or someone desu!" Suu added. Miki was thinking about something, "Yes Amu-chan, your mom looked quite happy, and she said you would meet him tonight, save your hate after you meet him." Miki added, and I sighed. "But he has a son. Boys are cold hearted bastards..."

"Now, that's not very nice, little girls shouldn't use such colorful language..." I heard a husky voice say from behind me, I jumped and looked back to see a guy, older than me by a few years, look down at me. I stared into his dark blue eyes, they were very mesmerizing. Then something rang threw my ears, 'Little girl'. I clenched my fists together angrily, and I felt my face get a little red. "I'm not a little girl!" Then I looked down and noticed that he wore our school uniform.

I felt something settle on my chest, and my eyes widened. I looked back to his face, seeing a thoughtful expression on his face. "No, I'd say your a little girl for a year longer at least..." I felt my face turn immediately red, so I tried to back away from him, yet I was unable to move. I noticed two navy blue cat ears on his head, and then I saw a cat tail wound around my leg. I looked up to see a small cat chara next to his head then, and he floated towards Ran, Miki, and Suu.

"Let go of me pervert!" I stammered, finally able to move again so I shoved him and covered my chest with my arms. I glanced down at my medium sized chest and glared at him. Geez, pervert my chest isn't small! He smirked and walked towards me, the chara change wearing off. "So, you have charas kid?" He asked as he looked at Ran, Miki, and Suu. I glared and nodded slightly. "Yeah, so? And I'm not a kid!" He let one of his eyebrows raise. "Sure sure, don't worry hun, they'll teach you all you need to know this year about..." He leaned foreward until his lips were against my ear, making me jump. "..sex ed." He finished, and my face turned even more red.

I saw him lean back just avoiding my hand, and he smirked. "See ya kid." He called over his shoulder as he walked away, and it was then I noticed us in front of the school. Everyone looked excited, and they were all screaming like girls, even the guys. I sighed and walked toward the school, my 'cool 'n spicy' character kicking in. I heard my friend Nagehiko call to me so I turned. "Amu-chan!" He called once more before stopping next to me. "Why were you with Tsukiyomi-san, Amu-chan?" He asked me, and I felt my eyebrow raise in confusion. "Eh? Who's that?" I asked as I tilted my head to the side confusingly.

"Tsukiyomi Ikuto-san! He was the guy you were just talking to!" Nagehiko said patiently, he was smiling gently at me as always. "Oh! You mean that snobby 11th grader who is like, an idol for that grade?" I asked boredly, and Nagehiko nodded. "That was him? he was a jerk..." I muttered quietly, and Nagehiko laughed, and he slung his arm around me as we walked towards the school. "So tell me Amu-chan, how was your morning?" I felt myself flinch.

(Ikuto's POV)

I couldn't help but laugh at what she had done. She was so red after I messed with her! But I felt my face fade into it's usual scowl as I approached the hallway where my locker was. All the girls squealed with delight and I glared, making them back away temporarily. I unlocked my locker (Tongue-twister!) and began shoving my bag into it, when my friend Yuu come up to his locker. He smirked and spoke, trying to get my attention. "Yo Ikuto, I heard your dad found another wife, it true?" He asked, and I glared. "He's my step-dad, and yeah, I honestly don't care. She'll be gone when the first month is up. He's making me meet her tonight." I muttered as I closed my locker, and Yuu looked shocked.

"Seriously? It was true? Does the new-wife have any kids?" Yuu asked, clearly intrigued as we walked towards our homeroom. "He said something about a daughter in 9th grade..." I muttered, and watched as Yuu walked off towards the class. "You think she's a cutie Ikuto?" He called out over his shoulder, making me smirk. "Ikuto, are we going to class nya?" Yoru asked me tiredly, and I shook my head, he giggled mischievously as we both started for the door, walking out and heading for anywhere to sleep.

Earlier this morning (still Ikuto's POV)

"Ikuto, I'm getting married." My step-father stated simply as he watched me about to walk out of the door for Easter's apartment building. "So? What's that got to do with me?" I asked boredly, glancing at him. "We're going to move into their house, her daughter has three hearts' eggs, besides that, we have a thing for each other. So, try to keep her daughter preoccupied." He said as he moved closer, his sadistic smile spreading over his face. "I don't want to mess with some kid..." I muttered, not really caring about any of this.

"She's not so little, she's a 9th grader, 15 years old." He added, and then turned around. "No more talk, you will meet Hinamori Midori and her daughter tonight at 6. We'll go to their house, don't be late." He turned slightly and handed me a piece of paper with an address on it, I sighed and took it and headed out the door boredly, starting to walk to school.

(Amu's POV)

"What do you mean your getting married?!" I shouted, making my mom cover her ears. "Please be calm Amu-chan, Yuichi is very kind and gentle. (Yuichi Nakamura is the guy who plays Ikuto's voice! SO cute! Btw, only name I could think of Dx) You will like him and his son a lot." She added, smiling slightly, my face was bright red with anger, tears brimming my eyes. "Please be back by 6 today Amu-chan, you get to meet him." I turned and started for the door, I opened it and started out. "Don't worry Amu-chan! The Tsu-" I slammed the door shut before I let her finish, and I ran out and towards the school angrily.

Lunchtime

I decided not to eat lunch with my friends, since I knew they would be curious about why my mood was unusually sour today, so I was sitting under a tree, slowly picking at my food, not exactly wanting to eat it. I lifted a piece of sushi with my chopsticks, and examined it. But before I could put it in my mouth, I saw another mouth close over my chopsticks, and I turned to see him, Tsukiyomi Ikuto.

He chewed, and a smirk appeared on his face, I glared and let go of my chopsticks, letting them fall onto the small tray in my hands as I pushed it towards him. "What? Little girls have to eat to grow big and strong you know..." He murmured, getting closer to me, which made me scoot away. "I'm not a little girl, for the third time, Tsukiyomi-san..." I muttered, and he examined the tray in his hands, then looked up to me. "Don't you mean sempai? You should respect those higher up than you."

I looked away from him, and I noticed Ran nodding at me. "He's right Amu-chan! Respect!" she whispered into my ear, and I sighed. He didn't seem to hear her, since he had picked up a piece of sushi and held it in front of my face. I leaned back, but he simply moved it closer. "I am not going to eat tha-" I was cut off as he shoved it into my mouth, and pressed my mouth closed, making me chew and reluctantly swallow.

"There, now you are one swallow closer to being full-grown." he said patting my chest, and my face turned red. "SHUT UP PERVERT!"

Later, walking to Amu's house

(Ikuto's POV)

I held the small piece of paper with the address on it, and I sighed, and then I noticed when my step-father's car was in fron of this fairly large house. I glanced at the address, and nodded when I walked to the door and knocked. A kind looking woman answered, followed by the devil himself. "You must be Ikuto-kun!" The woman greeted me happily, letting me inside. I nodded and glanced at him, and he smirked. "I'm so sorry for being late Hinamori-san." I bowed my head slightly, and she shook her head. "It's okay, don't worry about it."

I looked around, noticing only them. "Didn't you say she had a daughter?" I asked him, and he nodded. "Oh, that's Amu-chan, she's upstairs doing her homework, one moment..." she walked over to the stairs, and shouted up them. "Amu-chan! Yuichi's son is here!" She called up, and a very familiar shout followed. "I don't care! I'm not coming downstairs!" I smirked and walked towards her, Yoru following close behind. My step dad grabbed my shoulder and turned me towards him. "Find out about her charas." He whispered, and I nodded, walking towards Midori.

"Don't worry Midori-san, if it's okay for me to call you that," I paused, and she nodded immediately. "If you don't mind, I think I'll go get Amu-chan for you." She thought for a moment, placing her pointer finger on her chin. "Okay, that may work, go ahead, the room at the end of the hallway." She directed, and I nodded, heading up the stairs.

(Amu's POV)

"Ne Amu-chan, you shouldn't yell at your mom like that..." Miki scolded me slightly, and I sighed, lying back on my bed, holding a pillow to my chest. "I don't care, I don't want to be close to some other strangers..." I looked down at my chest, and I couldn't see my stomach, I sighed frustrated, and threw the pillow on my face. My chest is not small!

I heard a knock on the door, and I rolled onto my side, facing the wall. "Go away." I said, and then I heard a louder knock. "Go away." I said louder, and then I heard the door slowly click as it opened. I looked back to see Tsukiyomi Ikuto, and my jaw dropped. "What're you doing here?!" I stood and began pushing on his chest. "Get OUT!" he gripped my wrists and pulled them above my head, and he walked, making me back up, until the back of my legs bumped my bed.

"Now now Amu-chan, is that any way to talk to your onii-chan?" He asked as a familiar smirk slowly appeared, my eyes widened, and my face turned red. "ARE YOU KIDDING ME?!"

Hector: Okay! All done! Did you enjoy?

Ikuto: You know it. -smirks-
