So, this will probably be short. Like... I have it planned out in 4 chapters. Sooo... we'll see where this goes?

Rin Kagamine's first word was not very normal. It was not "mama" or "dada" like most children. Her first word was "wen."

At first her parents thought it was just childish gurgling. "Wen! Wen! Wen!" The high-pitched voice would come from the girl's crib. It was always happy. Rin was a happy baby.

Her parents eventually figured out that "wen" was a word, and they immediatly thought that she meant "when." It wasn't until Rin was two years old that she was finally able to say the word correctly.

"Len."

In addition to being a happy baby, Rin was rather odd. She would often sleep on her side, her tiny fists reached out and closed around empty air. It was as if she was holding a tiny hand in her own. She would often stare into empty space in the crib next to her, laughing and clapping happily.

As Rin grew up, she added to her vocabulary, but "wen" stayed there. As soon as she learned to walk, she would toddle around the house, laughing. "Wen! Pway!" This would be followed my a series of giggles and unintelligible mutterings. It was odd, but no one questioned it.

It wasn't until Rin was three that her aunt asked about the mysterious "Len." By this time, her mother had figured out that "Len" was a person, but didn't ask about it. In fact, she avoided the subject as if it was the plague.

"Rinny?" Rin looked up at the sound of the mature voice.

"Yus, Aunty Meiko?"

Meiko smiled down at the girl. "Who is 'Len?' " At this question, Rin smiled widely.

"Len's my friend~!" She held out the word "friend," drawing it out until she was nearly singing it. "We're gonna go play now, bu-bye!" Rin giggled and ran off. Meiko watched as the girl sat on the ground, rolling a ball towards the wall. It bounced off and rolled back to her. Maybe if she really looked, she would have noticed that she wasn't putting enough force on the ball to make it roll all the way back to her...

Meiko had a talk with her sister when she came home. "Yo, sis... do you think Rinny's alright... you know, in the head?"

Mrs. Kagamine looked like she had been slapped across the face. "Meiko! I told you not to drink when you were babysi-"

Meiko interjected, shaking her head in denial. "I wasn't drinking! It's just... she keeps talking to someone who isn't there."

Mrs. Kagamine crossed her arms over her chest, looking at Meiko a bit condesendingly. "Children have imaginary friends. It's perfectly normal."

Meiko glanced over at Rin. The girl had fallen asleep on the living room floor, curled under a blanket. Half of the blanket was spread out, as if to cover another form. Her hand was also held out, as if she were holding hands with someone. Meiko turned back to her sister. "Yeah, but... I think she really thinks that this 'Len' kid is real."

As soon as Meiko said the word 'Len,' Mrs. Kagamine's face went white. "No... she doesn't call him that! That's not his name!" In front of Meiko's shocked eyes, Mrs. Kagamine rushed to her room, slamming the door.

It was Mr. Kagamine who explained the situation to her. When he did, Meiko's eyes widened, and she shook her head. "If that's the case, then I don't want to deal with it. I'm outta here." Meiko didn't come visiting much after that.

When Rin was five, Mr. Kagamine took her to see a psychiatrist. He assured him that everything was perfectly normal, every healthy child is bound to have an imaginary friend. It didn't mean your child was crazy, they were just creative.

Mr. Kagamine was hesitant before asking his next question. "What about... the name? Is it coincidence?"

The psychiatrist smiled sympathetically. "Mr. Kagamine... I know that you and your wife have been through hell. To have twins is a blessing, and to lose one during childbirth... it really is heartbreaking. But you have to stop seeing ghosts behind every-"

"We were going to name him Len! How could she know that?"

The psychiatrist didn't seem suprised or offended by this outburst. "Are you telling me that you never discussed him in front of Rin?"

Mr. Kagamine rubbed the back of his neck, looking at the ceiling. "Maybe when she was very, very young... but there's no way she could remember that!"

The psychiatrist smiled again, a bit indulgantly this time. "Children have fantastic memories, Mr. Kagamine. She'll forget eventually."

Mr. Kagamine left, not at all convinced.

When Rin was nine, Len unexpectly left. His disappearence was ten times more frightening than his being there.

Mrs. Kagamine was doing dishes, when Rin suddenly started screaming. Mrs. Kagamine dropped a glass on the floor, then rushed up to Rin's room. "Rin? Honey, what's wrong?"

Rin was lying on the ground, screaming like someone was torturing her. No one was in the room however. Eventually, Mrs. Kagamine was able to make out one word. "Len! Leennn! Leeeeennnnnn!"

Mrs. Kagamine gathered the sobbing child in her arms. "Rin? Rinny, please, calm down! What happened?" Rin clung to her mother, crying hysterically.

"L-len's g-g-gone, mama! H-he said... h-h-he s-s-s-said..." Rin burst into fresh tears and was unable to get the words out. Mrs. Kagamine sat the child in her lap, petting her hair and trying to get her to calm down.

"Honey, just tell me what happened, it's okay, it's all alright, just tell mommy what happened."

Rin finally calmed down enough to speak. Stuttering constantly and occasionally sobbing, Rin got out her story. "Len disappeared! He said... he said he was breaking the rules. I told him not to go, but he said he had to! Mama..." Rin looked up at her mother with watery eyes. "Why? I thought Len was my friend. Why did he leave?"

Mrs. Kagamine sighed, before telling Rin everything. Len wasn't real, he was imaginary. She was getting to be too old for imaginary friends. It was time for her to let Len go.

When Mrs. Kagamine left her daughter's room (the girl had fallen into an exausted sleep), she was suddenly aware that she had been crying.

Eventually, Rin was able to convince herself that her mother was right. Len had been imaginary. Eventually, she forgot all about him. She lived a fairly normal life. She had a few friends, but they weren't close. She mostly kept to herself. She never really felt a connection with anyone... it was as if half of her was missing.

That missing half came back to her on her sixteenth birthday.
