Chapter 1
Yuka's pov
My name is Yuka Komori. And the girl who was sitting in front of me, is my little twin sister, Yui Komori. Yui looked so nervous. Well, that's usual, because of our father, who needed to go abroad, we were moving to other house by ourselves and that's why she was nervous. Not moving, correctly, but we had to live with others. So right now, me and my sister were riding on a cab in order to go to this new home. But I'm not happy right now. Nope, not at all.
"How are we going to survive in the house full of boys?" I said. At first I asked my father about the number of boys, but then I was shocked at the answer. He said, he is not sure but he bet there were quite a lot.
Yui rolled her eyes to see me. She already knew that I don't like males.
"But Yuka ne-chan, not all the boys are bad. I hope they will treat nice to us," she said. I twitched my eyebrow. Did she said hope? Yes, hope. That means she was not sure about the boys. What if they are kind of psychos? What if they are quite mad at girls?!
"Yeah, yeah, if you're saying that, then I am the one who is overreacting," I said in a halfhearted way. Yui giggled.
I looked at her outfit. She wore a pink sweater above a black tank top, brown shorts and brown boots. That didn't matter to me, but as I looked at the sweater whose sleeves were rolled down her shoulder, then her bare legs, my feeling of anxiety rose up. Maybe I should look around carefully, if there is someone who dare to touch her. Then I scanned my own outfit. I wore green hood with black hat on it, and black T-shirt underneath it. I wore tight blue jeans that showing my leg lines with black sneakers.
And this is the secret. Even Yui didn't know this. I wore a really strange watch on my left wrist. It was black, and has a round circle in the middle. The circle was colored green in a shape of an hourglass, and black filling the rest. I get this in my age of 10; when I lost in the woods after separating with Yui, I fell in a giant hole. There, I saw this watch. It suddenly jumped on my wrist, surprising me. I tried to get it off, but it stucked tight, so I gave up to remove it that time. Then I noticed that after pressing a button on its side, the circle part pop out, and if I press it down when a black figure formed, I can turn into one of 10 aliens! Well, for 7 years, I found out that I can turn into more. More than twenty aliens! Twenty-two, if I'm correct.
It was so cool when I knew this, but I kept it as a secret. When I transformed into a giant crystal alien, which is my very first one, I was excited at first. But then, I bumped into some kidnappers who had Yui on their arms. I got so mad, so as they were frightened by me, I punched, causing them to fly towards the tree. After that, Yui didn't noticed me, and just as I tried to explain to her, I realized that I should keep this as a secret. Who knows, dangers might happen around us. Plus, I didn't want to let Yui hurt. So, I'm keeping it as a secret. No one, not even Yui, will imagine that I'm the one who could turn into twenty kinds by the watch which I'm hiding under the sleeves.
"I wonder where is that crystal-woman now. She saved me 7 years ago," I flinched when Yui said that. "Remember the time when we lost in the woods? I was captured by some kidnappers and then this crystal-woman suddenly appeared. Then with a punch, she saved me! I don't know who she was, but I know she is doing only good things. We saw them a lot in the TV!" I smiled at her awkwardly as she started getting excited to speak about the aliens.
After I got this watch, I started to use its power to do good things. Every time there was a crime, I, as an alien, was there. It was always simple. Crime happened, I solved, crime gone. However, when I was in a form of a plant creature with vine legs, reporters tried to interview me, so I got away. And then, every time I appear, the news always report about me. I swore that I'm not going to let my secret being revealed by the others, and when the time comes, I'll tell the truth with my own mouth.
As the cab reached the place, I grabbed my luggage while Yui grabbed hers. I stared at the enormous mansion. Yui did the same. We looked at each other and then the mansion. Father, are you sure we are going to live here? We stood there for a while but I stepped forward and pushed the gate. The gate opened with a big creeeek sound. I looked at Yui and she looked at me.
"So... Shall we go?" I asked. Yui looked at me and the mansion with a confused look. "Are you going to stay there for a whole day? It will be great to wait until night so the boys could hunt you." I added.
Then Yui flinched. But she didn't flinched because of my word. And I flinched for the same reason just like her.
A raindrop.
The sky became dark and cloudy. And then some raindrops started to fall. ...Wait, rain? Then that means...
'Ka-boooom!'
"Kyaa!" Suddenly Yui screamed. Also, I flinched because of her. Uh-oh, she is afraid of thunderstorms. I slapped my forehead with my palm before I grabbed her hand to bring her to the front door. Yui panted because of the sudden run. I looked at the outside and saw the rain becoming strong. Then, with a creepy sound, the front door was suddenly opened. While Yui froze for that moment, I peeked inside. No one was standing behind the door. That made me goosebumps.
"OK... I know there are some people who are waiting for us, and it is raining outside, then someone might open the door when there are two girls avoiding the rain in front of their house," I said, slowly rolling my eyes to the frozen sister. Yui seemed to be in a cold sweat. "But why there are nobody in here?"
That made Yui shock. She shivered. I slowly stepped inside and Yui followed me. As we entered the house, I saw some stairs. A big and wide stairs covered with red carpet. Above us, was a big beautiful chandelier hanging in the ceiling. Do they... Really live here? This place is...
"They are... Rich?" I said finally. Just then, I sensed the bad feeling. I slowly turned around and realized... Yui was gone. I was shocked and walked the way we came. I knew Yui followed me to the house, and, she's GONE?!
Yui? Yui! I thought to myself, still in panic. Oh no, did they get her? Is she caught by them? What am I going to do?! What am I going to do?!
As I kept finding my sister, I heard unfamiliar male voice. "How dreadful. It's rude to sneak around in other people's home, even in the entrace hall," it said. Wait... Male? Did I just say that?
I turned around and surprised at the man wearing a nice clean uniform. He had a hair being a shade of purple-black, combed neatly against his neck, with his forelock slightly across his nose below the glasses that was matching with his red eyes. Also, he was wearing a red vest with yellow buttons, a white belt around his waist. Under the vest was a black dress shirt with a perfect red tie tying neatly its collar and his neck. He was wearing a jacket, too; a shade of dark red? I guess. Finally, I scanned him wearing a black pants and shoes.
I wonder why he is wearing a white glove only on his right hand? I thought as I saw his right hand along with his arms crossed. Just then, my eyes widen. This is not the time to spend with a man! I quickly spoke out.
"Um... I'm sorry to get inside here without a permission, but I think I lost my sister, Yui. May I find her for now?" I said before he raised his eyebrow as a confusion. Then I realized now about his face. Woah... He has a quite good look... And he is tall...
"And may I ask who you are?" He spoke. I fluttered at his cold aura and with a gulp, I stated.
"Yu, Yuka Komori, who was told that I should live here with my sister," I shivered, still taking the man's stare. Then, suddenly he raised his right hand to his chin, as he started to think of something.
"Never heard of that," he said. ...Wait, they don't know?! I stood there for a moment until he made a decision. "Very well. You may look for your sister, for now. But I think I already found her."
With a blink, I shocked. "What? Did you find her?!"
"Yes. Follow me," he said before I started to follow him. Then, he stood. With a cold voice, he called someone.
"Ayato, just what are you think you're doing?" I peeked over him and saw a boy with short messy red hair, light green eyes with a good look like the man in front of me. But that didn't grab my attention. He was pinning down Yui, on the coach. My anger slowly build up, dark aura came out.
"The hell, are, you, doing to my sister...?!" I growled. The boy looked at me and frowned with an annoyance. Suddenly, Yui pushed him, and managed to get out. I sighed with a relief. Yui hugged me. Well, she might terrified of that, because no one had done to her that way before. I glared at the boy-Ayato, if I heard right- and he glared at me. In your dreams. You'll never touch her when I'm here. I thought to myself.
"So, we've found your sister, how about going to the living room and talk about you more?" The man turned around and asked me. I looked down at Yui who was shivering a little and then nodded with an agreement. Then a butler suddenly came out from nowhere, grabbed our luggage and moved backward, disappearing to the dark hallway. Ok... That, was creepy...
"Yui, whatever this place is, I, definitely not think these males will treat nice to us," I whispered to Yui. Yui couldn't help but agreed with a nod.
So... How was it? Well, I think I messed up. If you enjoy, please review!
