A/N.: To the readers who have read my fanfic on Accel World named "Arc-en-Ciel" ("Rainbow" in French language) in the past, here is the remake of my first fanfic, I thought about it for a while and rewrited the same unchanged storyline with some modifications though, this time as a crossover between Accel World and Sword Art Online. In my story, the story of Accel World would take place after Sword Art Online and the characters of the latter would be at least mentioned and being related to my OC in a way. Please enjoy and review!

"Did you knew? That virtual world was infinite, even more than the real world where we are living." One day, all of the sudden, such a thing was told to him.

A young boy under 10 years old with slightly wavy wine-colored hair and hazel eyes were looking at the middle-aged man from over his shoulders, he was currently playing playing games online with him. "Why suddenly?" He asked so because his uncle suddenly blurted that out of the blue, and he was so taken aback the timing that he missed the final step in his game turn and lost against the final boss. "Aah! I lost! Because Uncle said something like that all of the sudden I lost!"

"Eh? I am sorry, I didn't excepted you to stop suddenly like that." The man apologized wryly. He had short black hair that start to turn grey due to him aging and black eyes.

"Uu... It was a world tournament and I lost it..."

"I–I'm really sorry." Seeing how much the boy was saddened over the loss, the man apologized, "But there would be other occasions so don't be too depressed about it, okay?"

"Uncle is just saying that because he is trying to get himself out of trouble."

"Ahaha... Did I got found?" The older man laughed awkwardly.

"Because of that you always make Auntie angry!"

"So you know about that too...?" Although the two weren't related by blood, his parents were strongly acquainted with this man and they often met with each other, now they considered each other as family and he called him 'Uncle' by courteasy. Because if he were to call his wife 'Grandma', she would get angry even though he doesn't mind it particularly being called 'Grandpa' since he had yet grandchildren. The boy also seems to have inherited his passion of games much to his wife's disappointment, and because of that the two argue from time to time but still act as newlyweds. It was currently during summer vacation and the boy didn't needed to go to school, he stayed at their house when her parents are too busy with work.

"But I didn't told her that I let you participate at a world game tournament so let's keep it a secret, shall we?" He shushed the boy, brought him on his laps and tickled him on the sides, he did his best to hold his laughter as he was shaking and almost fell from his laps. "Ahaha~! Uncle, it tickles!"

"Is that so? Is it over here? Or over there~?" He didn't stop with his tickling hell and the boy jumped out of his laps for redemption, "Phew... I thought that I was going to be a goner..."

"Don't say such a thing when you are still a kid. It's going to bring back misfortune in the future."

"Eh?! Is that so?!"

"Kidding."

"Geez~!" The little boy hit at the man's chest with his tiny fists rolled into punches. Of course it doesn't hurt, on the other hand it was incredibly soft, a child's strength can't hurt an adult after all, so the older man only laughed in response. "Ahaha! Got it, got it! Please stop~" Of course his voice sounded more amused than pleading for something truthfully, the little boy noticed that and pouted in response.

Suddenly the boy was reminded of something and then asked, "By the way didn't you said that virtual world are more infinite than the real one? Why did you said that?"

The man was surprised that the boy managed to remember his earlier words after all this time and smiled to himself, "Nothing that you needs to know for now, just something that your parents and us are working on, I'm sure that you'll understand one day." He refused to tell more no matter how much the boy asked about it so he gave up in the end.

"Shinkkun~? Are you there~?" Suddenly another girlish voice called the boy from outside by the window, it was a girl slightly older than him with light brown hair and light blue eyes, she was waving at her, "We are going to play all together but are you coming~?"

The boy with wine-colored hair and hazel eyes, recognized the girl in front of him with a smile immediately growing on his face. "Fuu-chan! But..." He looked at his 'uncle' hesitantly on wherever he should left his sides or not. He just smiled in response and waved him to go on. "Just go, Auntie would be angry if I keep you here playing online games all the time with me."

"Hn... I promise I'll go back before dinner!" With that the boy ran outside to his friend.

The man, him, just stared at the cloudless summer sky that was presented to him from the opening of the window and was reminding himself of the time of the past he lived through with his friends and what he should do for the boy from now on.

[A few years later...]

10 years later, a young man in his teens currently with wavy wine-colored hair and hazel eyes was looking at himself in a mirror, he was wearing the uniform of his new school. He looked at the photo in his room, showing himself and an eldery couple, the man from his memories and his wife.

He then gave a last look at himself in the mirror. 'It's alright, isn't it? I don't look weird anywhere, don't I?' It was a little embarrassing to see himself checking on his appearance but it was his first day in school since a long time so he was kind of nervous right now. Would he be able to make new friends at the school where he would be transferred? He gathered his courage with such thoughts and clapped his cheeks twice in determination after taking a deep breath, even though it had yet started he was already so nervous~

"Shinkkun~? It's almost time go~!"

"I got it! I'm coming down right now, Fuu-chan!" He gave a last look to the photo he treasured so much before descending down the stairs and joined the person calling out to him.

'Uncle, Auntie, please wish me good luck!' This was the beginning fo a new lifestyle, Nikaidou Shinku was going to meet other people similar to him at Umesato Junior High School.

A/N.: I will also include the Accel World x Sword Art Online game in this fic. There is no YAOI allusion in this chapter! The earlier presented scene is just the typical scene between a parent and his child or more precisely an eldery uncle and his really young nephew here! Shinku was originally supposed to be of female gender but I have decided to write about a male one because I have noticed that I wrote too much fanfics with female OCs, the plot is the same though, don't worry! As long that you are fine with a male OC... besides "Shinku" can be a name for both boys and girls (I checked it myself!), though it is more of the latter than the former.
