Author's Note: I do not own Monochrome Factor and its characters. Reina Nikaidou is my original character.

"Reina. Reina Nikaidou."

Silence. Shirogane peeked at Akira's reaction with his eyes still hiding under his hat as usual. The girl who was claiming to be someone from the Nikaidou family sat still beside Akira's bed.

"So? What brings you here?" Akira finally asked.

"Do you… Do you remember me?" Reina moved closer to Akira, her eyes sparkling with anticipation. Akira leaned back to his bed's headboard.

"Aren't you my cousin or something? It's the first time I've met someone with the same family name as me. Oh right. Father is there but he rarely comes home anyway."

"Cousin? Me? Do you really not remember me, Nii-sama?"The girl stopped herself, putting both her hands on her mouth but it was already too late. She felt something boil inside her and she had to let it out. Her hand moved on its own and left a stinging pain on Akira's left cheek.

"I hate you. I hate you Nii-sama!" The words slipped out of her lips. She thought that he would always think of her just as she had done all these years.

This wasn't how she imagined their first meeting to be. She stood up and dashed out of the room.

"Hmmm." Shirogane let out a deep sigh of disappointment.

"What was that all about?" The annoyed Akira asked, holding his left cheek. Shirogane chuckled at the sight of the red hand mark on Akira's left cheek. He remembered the first time he got on Reina's bad side.

"You really don't know how to talk to a woman properly. You haven't seen her in years and you make the poor girl cry. What a mean brother you are, Akira-kun."

Meanwhile, Reina continued to run outside their house as if someone had been chasing her.

Why did I slap him? It wasn't his fault that he can't remember. We both decided on it. I should have given him more time. It has been 11 years after all. And I even said I hated him. While I am his twin sister, I am also his…

She came to a stop when she felt the presence of another Rei. She looked around and found herself in front of a bar.

"Aging bar? I'm a minor and it's still closed. Maybe..." Reina wiped away the remaining tears in her eyes as she stepped in front of the bar's door. She knocked twice. Not hearing a response, she decided to enter the place. The door creaked as she turned the knob and slowly let herself in.

"Good evening. I'm sorry to intrude but I'm looking for someone."

Her footsteps echoed across the room. The seats were still turned upside down over the tables. She walked towards the man beyond the counter. The more she got closer, the more she was certain that he was a Rei.

"I haven't heard these footsteps before. Who might you be young lady?" The bar owner asked.

"I am Reina. Reina Nikaidou. And like you, I'm a Rei. Could you be the other king, Shisui?" There was no hint of doubt in her voice. The bar owner looked exactly like the other king in her memories. To be more precise, his memories. She took a seat in front of the counter following the gesture of the owner.

"That was fast, Reina-chan. Your powers truly are amazing. Right now, they call me Master but what brings you here?"He asked as he gave her a glass of water. The question struck her and she wanted someone to hear her out so she explained everything to him.

"So you ended up slapping your long lost brother?"

"But I really didn't mean to. I was worried about him all this time." She let down the glass on the table as if punctuating her line.

"Please don't put your anger on the glass Reina-chan." Remarked Master.

"I'm sorry. It's just-"

"Just what?" The voice said behind her. She knew exactly who it was without having to look back.

"Ah. Akira-kun. And Shirogane-san as well." Master called out as he felt the presence of the two as they entered the bar.

"I am not apologizing to you." Her tone was defiant. No way was she letting her loneliness get the better of her again.

"Who says I want it? I probably deserved it anyway. And…"

"And?"

"Are you really my sister?" Akira reluctantly asked as he sat by the left seat beside Reina. After recounting her story to Shisui, she was already able to clear her head. And right now, she knew exactly what to do.

"You never had any of your childhood memories, did you? The reason was because I- No. We decided that it was the best thing to do back then. But now, it is different. Hold out your hand." She commanded. Being the elder among the twins, she had every right to use this tone on Akira.

"Why should I?" It was in Akira's nature to be stubborn. Master and Shirogane both stared at the two of them, awaiting how Reina would pacify the king of carefree life. Akira gulped and finally resigned himself to the raven-haired girl after seeing her burning glare. He didn't want a slap on his other cheek too.

Reina took his hand and raised it as if they were both making an oath.

"Just follow my lead okay?" She whispered. Akira turned red after feeling his sister's breathe close to his ear. She couldn't help but giggle at the sight of his blushing brother. Reina took a deep breath and chanted.

"Hear me, keeper of all memories. I am the bearer of the key. By my command, release the seal!"

The two were suddenly engulfed in a bright and warm light while the other two kings sat patiently and observed. Only Akira and Reina saw the memories flashing before them like a movie strip. It was all true. The boy and the girl. They were inseparable. The Nikaidou twins.

The memories he didn't bother to think about. He never had anyone to ask anyway. His father was always out on business trips. He has no recollections about his mother. Let alone having a sister. Five years worth of childhood memories were now returned to him.

The light that surrounded them slowly faded away. The two still held each other's hands. No one had the courage to speak when Akira leaned his forehead on hers. Startled she may be, she didn't have the energy to resist. Not after using her powers like that. Then again, she longed to be close to him like this for the longest time.

Realizing that he was not alone with his sister, Akira quickly outstretched his arms and released Reina from his grasp. He put his hand on his face, hiding his embarrassment.

"This doesn't change my first question. Why are you here?"

"Shirogane-san, when I returned Nii-sama's memories, I saw something in him." Reina started, evading Akira's question. She stood up from her seat and slowly went to where Shirogane sat, just a few seats away from her and Akira. Shirogane twitched at the memory of his first encounter with Reina. He may be the King of the Shadow World but it was nothing before the face of an enraged sister.

"Uh. Reina-chan. I'm sure you also saw the circumstances back then. If I didn't turn him into a Shin, he would have died." The silver shadow said with a smile but his voice was shaking.

"But because of that he is limited. He can't turn into a Rei." She sighed. Reina turned back to Akira and faced him with a firm resolve.

"I am answering your question now, Nii-sama. I didn't just come here to return your memories and be by my brother's side. I came here to protect you and help you in your battle with Homurabi."
