Miku Hatsune, a six years old child stood behind her parents. She could heard that her parents were discussing something with someone. From the voice she could tell that the person was a man.

Miku was blind, she couldn't see anything, so she relied on her parents too much. And today her parents said to her that someone will take her to faraway place.

Maybe this man is that someone, she thought. Suddenly she heard her parents called her and she walked to them.

"Miku," her mother said "from now on you will live with master Rei, understand?"

Miku just nodded without asking anything about that certain person named Rei and suddenly she felt someone took her little hand, maybe it was the man. Miku could felt that his hand was bigger than her and it was cold, but even this man was a stranger, she felt protected by his presence.

This man walked out from her house and she followed him, and then she realized something. This is winter, and she hadn't bring her mantle with her.

"Aren't you cold in just that?" suddenly the man asked.

Miku was surprised by his voice, she ever heard it when he talked to her parents but she didn't pay any attention that time. Now when she heard his voice again, she realized how clear and tuneful his voice is.

Slowly Miku nodded her head and yelped when that man suddenly carried her and cover her body with something warm.

"Still cold now?" he asked again.

Miku shook her head, "Thank you," she said softly.

"No problem," he said to her and held her tighter, "Do you have a name?" he asked again.

Miku nodded, "Miku, Miku Hatsune," she said softly.

"Miku? What a beautiful name," he said and pat her head gently.

"How about you? Do you have a name too?" she asked him innocently and that man laughed at her and make her confused.

"No one dare to talk to me like that before," he said still laughing, "And I have name of course."

"What's your name?"

"Len."

Miku shot awake. What a strange dream, she thought and placed her hand on her head.

Miku Hatsune, a sixteen years old girl sat on her bed. She's blind so she can't see anything but she have a good ear and she could feel someone's presence if they near enough also she have special ability to remember someone with her touch.

Suddenly she heard someone opened the door and walked in to her room. That someone walked to her and stood beside her bed.

"Good night Miku," He said gently.

"Master Rei," Miku replied and smiled at him.

Rei's hand stretched to her and Miku took it and kissed his hand as a greeting to him.

Rei Kagene isn't even a human, He is a vampire. And tonight, he came to Miku's room as usual to take her blood that Miku always give to him.

Miku was just a human who lives in his castle to provide him her blood, in other words she was his was sent to his castle by her parents request and she doesn't know why.

She was supposed to be scared here, but he's always kind and gentle to her so she wasn't scared with Rei, not even a little.

Rei climbed to her bed and sat beside her. He placed his lips on her neck, "May I?" he asked for her permission and Miku nodded. His teeth sank into her skin until blood dripping from it and Miku moaned softly.

Rei hissed before he sucks the blood and make Miku gasp. When he finished sucking her blood, Miku breaths heavily and feeling a little faint.

Rei cupped her face with his hand, "Are you okay?"

Miku nodded and smiled at him, "That's okay, I always feel like fainting after you sucked my blood, it always happens so I'm getting used to it."

Rei smiled at her and trailed his fingers on her cheek slowly, "I can't be here from tommorow until next week," he said.

Miku looked a bit surprised by this, "Why?" she asked quickly.

"I have a matter to attend to. And I have to go to settle it."

Suddenly Miku trembled harshly. She's afraid if she was alone in this castle. This place was filled with vampire, she knew that there was a vampire who was similar as Rei that always kind to her. Like Rui, his sister and Gumi, a vampire that live in this castle too.

But she knew perfectly that there were vampires that wanted her blood too so they don't have to hunt for prey. Usualy Rei would always protect her from them but tommorow he will be gone for one week.

Rei notice that she is trembling and hugged her tight, trying to comfort her. "Don't worry about it."

"But master, they will make me their food if you're gone," Miku said and still trembling.

Rei released her from his hug, "That's why You won't stay in this castle when I leave tomorrow."

Miku looked confused now, "What do you mean that I won't stay here?"

"I will send you to another castle while I go to settle the problem." ," Rei said in serious tone.

"Where's the castle?" she asked him.

Rei smiled at her, but she couldn't see it of course, "Before I answer your question I want you to meet someone," he said and stood up.

Miku heard someone knocked the door, "Come in," Rei said and the door opened.

And a blonde haired boy with his sky blue eyes entered the room. Rei smiled at him and helped Miku to stand.

"Miku, I want you to meet my cousin, Len Kagamine."

The blonde smiled to her, "Hello Miku, nice to meet you."
