A/N: My first Digimon fanfic yay. If you could kind enough, please leave me a feed back? I would really appreciated it. Anything, really. So please, give me feed back and pointed my mistake? Especially since English is not my native language. Thank you in advance~ Oh, Italic means it was Flashback or Dreams. In this case, it was both.

Age: In the Flashback, Hikari 4, Taichi 7, Kou 7

Disclaimer: If I own Digimon, I own it, I will make the sequel where Adventure and Frontier's digidestinied was fought together. As in my head, those two has more than enough thing to be count as sequel/prequel.

"-Sono toki made, matta ne."

"-Until that time, see you later"

- From Y to Y

It was dark; the location and the sky. And she hated it. Especially since she was alone, in a strange place that she knew nothing about, and without anyone that she knew around.

Several hours ago

Several weeks ago, her father told the family that they need to move from Hikarigaoka since her father got promotion. And although the young Taichi Yagami was more than excited to go to the new place, Hikari was more confused as to why should they move, but she agreed nonetheless since her father said she would have more friends there. The first day in their new house was okay. The place was nice and Hikari liked it, so did Taichi. Not to mention there was any soccer field nearby. Hikari knew that her brother was so fond of that sport and he sometimes played with her even though she couldn't kick the ball as good as the other boy that played with her brother this afternoon. But just to feel her brother's presence near her was more than enough for her to feel safe, protected, and she loved her brother. He would never leave her alone.

But when Taichi was going out to play with his friends and refused to let her tag along, Hikari couldn't help but feel annoyed. Taichi had said it wasn't good for her to go out at her feverish condition and had promised her to play with her later. Hikari would usually obey her brother, usually, but her fever made her a little stubborn and she felt… abandoned? She doesn't know the feeling… not yet. All she knew was that her brother going out without her and that made her sad.

So without warning anyone in her house, she quickly chased after her brother, even though she didn't know which park that her brother went to. And before she could realize it, her tiny legs have led her to an unknown place. The location was unfamiliar; her house was nowhere in sight and neither was her brother.

Present

The four year old Hikari sat down under the lamp in the park, the only place that was bright enough for her. She lifted her knees up to her chin and wrapped her hand around it while she did the only thing she could do now; sob. "Nii-chan…" she sniffled, tears rolled down to her cheeks, "Taichi, nii-chan," she repeated, as she called for her dearest older brother. She knew he would come, after all, he promised her that he would always protect her no matter what. And young Hikari believed his words. There was no reason to doubt her own brother anyway.

However, even though she has wait and called out for her brother for a while, she still can't see his bushy brown hair anywhere in the dark park, and this scared her even more. "Nii-chan… It's cold… It's dark... It's scawiee…" Hikari continued sobbing and buried her head into her knees.

"Did you get lost?" the new voice asked, making her flinch a little and her body shivered at the thought of the bad guys that her mother had told her about. But for some reason, she didn't feel like the owner of the mysterious voice was bad. It sounds boyish, almost like her brother's voice and a hint of worry was clear in his tone. She remembered it, was the tone that her brother always used when he was worried about her. Gathering all her courage, Hikari lifted her head a little to look at the boy in front of her. He was about as tall as her brother, but half of his face was covered by the shade of the hat that he wore. She noticed that the boy tilted his head; most likely waiting for her to answer his question, the young brunette girl nodded her head slowly.

"Do you know where your house is?" he asked again, and this time Hikari shook her head as an answer to his question. The boy was silent for a moment as if he thought of something before he spoke again, "Then let's search for it together," he said, offering his hand to her, his lip turned into a smile.

Search for it

Those words sound promising to her and she took his hand, letting the boy help her to get to her knees.

"Don't worry, we'll find it. And if we don't we could stop by my house," He said, patted her head in comforting way. "I'm sure 'baa-chan and 'kaa-chan would help you to find your home also," He added, "Beside, you seem to have a light fever here."

And with that, Hikari felt relieved, at least the boy was nice enough to help her find her home and now that she got on her feet, she could tell that the boy was almost the same height as her brother. Though, when he mentioned her fever, she spontaneously put her hand on her forehead. It was indeed warm, which remind her on why she was here in the first place. Hikari glanced up at the boy; she thought that he would be mad. Unfortunately, she couldn't see his face clearly since her sight was blurry due to her crying recently, but somehow she could tell that it was just worry that present itself on the boy's face, not anger. The boy held her hand and begun to walk but when she stepped out from the light, she stopped, her body trembling and this rose a question from the boy, "What's wrong?"

"It's... d-dark... and scawie..." she muttered and held her free hand to her chest. She could feel the boy's gaze on his hand which was still holding onto hers before he stepped closer to her.

"Don't worry, the darkness is not scary," he said in reassuring tone. This made her look at the older boy in bewilderment and the boy seemed to notice it as he added, "It's nice, the darkness." But that does not make her any less confused, not a bit.

"How... it is nice?" she asked. Her question was answered by his index finger that pointed up to the sky. Hikari's brown eyes widen in amazement when she looked up. She didn't realize it earlier but now the boy mentioned it, she could see the glittering stars on the sky, "Pweetty..." she mumbled, her cheeks flushed in excitement.

"Isn't it?" the boy asked with a soft chuckle. "'Baa-chan said the darkness was nice because it gave us this view. If the sky didn't turn dark, we couldn't see the stars and the moon. And she also said the darkness was protecting the light and let it rest to make sure it's ready for tomorrow."

"So the night sky is protecting the light so it could rise tomorrow?"

"Yes," he nodded, "Even the light needs rest so it won't be exhausted when it has to do its duty tomorrow."

This made Hikari think for a moment before she mumbled, "Protect... Like my brother!" She exclaimed, a wide smile present on her face, replacing the scared one from before.

"True, 'Baa-chan also said light and darkness are also brothers. So... yes, I think that's why they protect each other, don't you think?" he said with a cheekily grin. The statement made Hikari's body stop trembling and she stepped out from the light with a nod and they began to walk, and he led her out of the park.

"By the way, I'm Hikari, Yagami Hikari," she introduced herself to the older boy. The boy however, seemed surprises for a second by the sudden introduction but he smiled afterward

"My name is Kou—"

"HIKARI!"

His sentence was cut off when she heard the familiar voice call out her name, she turned around and saw a familiar figure running around, searching for her, "Onii-chan!" she shouted, as she let her hand go from the boy's hand and ran to her brother who just noticed his sister.

"Hikari! I-" Hikari jumped and hugged him tightly, making her brother sigh as he patted her on the back, although he seemed to be a little annoyed that his sentence was cut off. "I'm worried you know… 'tou-san and 'kaa-san too. Where have you been?" he asked and then he leaned down to her level when she let go of the embrace.

"I—" Hikari paused and looked down, feeling guilty. "I just wanted to play with you. I'm sowwiieee... I won't do it again!" she whimpered and hugged her brother again.

Taichi knew that there was no point in scolding her, not when she already knew it was her fault anyway. Besides, Hikari's plea was something irresistible to him. "Fine, let's go home then. I don't want to make tou-san and kaa-san worried even more," he said as he held his sister's tiny hand. But before he could walk, Hikari stopped him, "Nii-chan wait, there's someone with me. He's nice!" she said, turned her head around just to found nothing. "Kou?" she muttered, searching for the boy's presence.

"Where?" her brother asked, "There's no one around." He added as he looked around. He knew Hikari wouldn't lie but where was the boy 'Kou' that she mentioned?

"But…" she trailed, head turned down a little in disappointment.

"Let's go home or do you want to make our parents even more worried?" he asked

She shook her head.

"Come on then," he said, leading his sister towards their house. And as they began to walk, Hikari turned her head around again to look for the boy who was nowhere to be seen. But when she saw a shadow near the nearby lamp, she let go of her brother hand and shouted, "Kou! Thank you! And let's play together sometime!"

From the shadow, she could see the boy, Kou's figure waved his hand toward her and she return the wave before she ran toward her brother.

"Matta ne..."

The sound of her alarm clock woke her from her deep slumber. It showed that it was six thirty in the morning. She reached out her hand, and turned it off before she got up and looked at the white furred Digimon at her side that was still sleep. She climbed out of her bed carefully not to wake her partner up and began getting dressed.

"Morning brother," Hikari greeted her brother in the dining room after she finished getting dressed and was prepared to go to school. Her brown eyes scoped around the room and found no one but her brother. Meaning, her mother has gone out early this morning. She did mention that she wanted to visit their grandmother yesterday.

"Morning Hikari." Taichi greeted back and noticed something's different from his sister. "Something good happened? You seemed to be so cheerful today." He asked with his usual grin on as he looked at his sister who now sat across from him.

"Mm..." she hummed, "Sort of; just a nice dream from the past," she answered and finished her breakfast before she took her school bag and jogged toward the door, followed by her brother shortly.

"Dream? What dream?" Taichi asked curiously as he locked the door and began to walk toward the school. It was good to see his sister in a good spirit but he couldn't help but wonder what Hikari was referring to.

"Se~cre~t" she sing song and earned a pout from her brother in return.

"That's not nice," he muttered.

And she just giggled to her brother's pout face before she lifted her head up. 'We will meet again right, Kou?' she said inside her mind.

Thank you for reading and review is always appreciated ^_^
