Introduction

Everyone knew that Seto Kaiba was the owner of the Kaiba Corporation. Everyone knew he was heartless, and that he had one brother, Mokuba. His rival was Yugi Moto, the King of Games. He was 18 years-old, and so on. But there was one thing they didn't know. He had a younger twin sister, Aina (a-yeena). She was separated from them, and placed in another orphanage, when Seto was adopted by Gozuboro, he adopted her too, but she stayed in the same terrible room. She slept on an old mattress on the floor, with a thick old blanket. The room had one lamp, and an added bathroom with a shower. The only problem was that nobody knew about her, was because Seto hated her. He didn't love her, he yelled at her all the time, and was a monster to her. He didn't talk about her at all. Why? Nobody knows. Mokuba loved her, she would always read him stories, play games, and sing to him. But this would all happen once a month. Seto had Aina locked up in a secret room in the company. And restricted her from seeing Mokuba, to only one time a month. And Mokuba knew not to speak of it. Watch as her life changes, by the help of some new friends.

"Didn't I tell you only one hour! You've been with Mokuba for and hour and thirty minutes! Don't you understand!" Seto yelled. It was 6:30 in the afternoon, he was under the grounds of Kaiba Corp. and to be more precise, 8 levels underground.

A girl his age was quivering in the corner. She had very long brown hair and bangs, blue eyes, pale skin, and small pink lips. "I-I didn't n-notice, I-I'm sorry Seto," she stuttered.

"You didn't notice, huh? And don't call me Seto! It's Mr. Kaiba to you!" He yelled, and slapped the girl across the face. His eyes full of rage, but her eyes were about to cry.

"Seto, that's enough, please, leave Aina alone, it's my fault," Mokuba said, holding Seto's hands. "Your fault? It's this worthless brat's fault, never defend her, she's worthless!" Seto yelled. He looked down at Mokuba, then smiled, come on, you've got to eat dinner and go to bed," He said, but calmly.

Mokuba slightly waved goodbye to Aina, and mouthed 'sorry', then Seto locked the door, and they both went upstairs.

Aina dug her face into her knees and started sobbing. 'Why does he hate me? What did I ever do to deserve this!' She thought. Her old shirt was soaked, so she had to change into another one, but it was old too.

All her life, she'd been deserted by everyone. All she ever wanted, was for her to brother to love her. But it never happened. The only person that was kind to her was Mokuba. And she loved him from all her heart.

"Seto, can I ask you something?" Mokuba asked, after dinner. "Sure what is it?" He said in his normal tone. "Why do you always yell and hurt Aina? Why do you hate her?" Mokuba said quietly. Seto grunted. "It's none of your concern, Good night," he replied.

Seto went to bed, and starred at the ceiling. The thought of her made him mad. He hated her, he didn't like to even look at her face. And every time he yelled at her he felt better. 'Maybe I should send her to the high school, get rid of her face for a while, tomorrow, yeah, it's a good idea,' he thought.

Aina sat on her mattress, and looked up at the ceiling. It was blank and empty, just like her life. She sighed and opened her closet. Under her old clothes, where papers and scrolls. She took one out, along with a pencil, and opened it up. It was a picture of Seto, smiling. Along with him stood Mokuba, and her.

For the past few weeks, she had been drawing it. She always imagined this picture in her head. Seto had and hand on Mokuba's shoulder, and one on hers. She hid them so Seto wouldn't destroy them. She had another one she was drawing that had Seto and Mokuba in it. She was planning on giving him it to him on their birthday next week.

She continued to sketch details. She used a pack of colored pencils Mokuba snuck into her room on her birthday last year. Then she started to color it, focusing mostly on Seto. Even though she was sad, she loved Seto from all her heart. Her dream was for him to love her as a sister, and for her to protect him.

Squeak. Squeak.

A small mouse hopped over to Aina. "Hey there little guy," she said patting his head with her finger. It squeaked again. "Sorry little guy, Seto got mad, I didn't get any dinner tonight, I'll make it up to you tomorrow, ok?" She said. It squeaked.

She went to the bathroom, took a shower, brushed her teeth, hid the pictures, and went to bed.

The next morning...

"Wake up you brat!" Seto yelled, throwing a uniform on the floor. Aina woke up startled, and quickly backed into the corner.

"G-good morning, M-mr. Kaiba," she quietly stuttered. 'He's going to hit me, he's going to hit me!' She thought. It was about 5:00 in the morning, and Seto glared with hate at her.

"Get up, your going to school, that's your uniform, go to the elevator to the main floor, your going in the limousine, be ready at 6:00," he said quickly, and slammed the door behind him. Aina was confused. She washed her hands and face, brushed her teeth, put her uniform on. It was a white shirt with a pink and purple jacket, and a pink and purple skirt. Then she combed her hair. She put her hair in a half up in a ponytail, and a pair of light blue heels.

Aina walked around the room, trying to get the hand of it, and she did. She fixed her room up, and went to the main floor. There, she saw Seto in a white suit, waiting. He threw a light blue backpack at her, and she caught it. "It has all that you need in it," he explained, then clenched her arm tightly, she tried to leave his grip, but he tightened more. "Please stop," she whispered.

"If you say one bad thing about me, consider yourself without food for a whole day, got it?" He said. She quickly nodded. He dragged her out the entrance, and shoved her into the car.

After a while, the limousine reached the school. "Have a good day," she said to the driver. He smiled, "You too," he replied.

She walked out of the limousine, and into the school. She opened her backpack, and took out her schedule. "Let's see, Algebra 2 in room 56-B," she muttered to herself. She looked around, looking for the class.

"Your new around here, want any help?" Someone asked. It was a white haired boy, and he was smiling. "Um... ya," she replied handing him her schedule. "Oh, Algebra 2! Me and my friends are in that class. Here, come with me," he said. She followed him.

They walked into the class, and she introduced herself to the teacher, and sat down with the boy. "I'm Ryou by the way," he said. "I'm Aina," she replied.

"Shut up Joey, Yugi is the champ here, you got beat by Kaiba, don't you remeber?" A brown haired guy said. He and his friends were walking torwards Ryou. "Hey, who's the new girl, she's pretty," Joey said, glaring at her, then at Ryou.

Aina didn't notice. But Ryou did, "Hey guys, this is Aina, she's new here," he explained. Aina looked up. There was a blonde haired boy with an idiotic look on his face, a brown haired boy who also had the same expression. A short haired girl, with the same uniform and a nice smile. Then there was a tri-colored, spiky haired boy, and he was kinda short.

"Hey, I'm Teà, nice to meet you," the girl said. "Hi, I'm Yugi, nice to meet you," the short boy said. "Im Tristan, and this goof ball is Joey," the brown haired guy said, laughing at Joey. "I'm a professional duelist, Joey Wheeler is the name," the blonde haired boy said.

"Nice to meet you too," she replied. It was nice to be greeted by people like this. They all sat down, and started to talk before class started.

"You look like someone we know, but who?" Joey said, eyeing her suspiciously. "You do look like someone we know!" Tristan said. "Wait a minute, you look like Kaiba!" Teà said. Aina nodded.

"K-kaiba is my twin brother," she explained. Everyone's chin was hanging open. Aina didn't know what to do. She couldn't say Seto, or he would kill her! "I know big surprise," she said quietly.

"But how come we've never heard about you?" Yugi asked. "Um... I... uh..." she started, but was cut of by the teacher, starting class.
