Hikaru has a twin brother. They are going to stay with grandparents because their father is relocated overseas by his company and their mother is coming with him. Sai is sickly older cousin/relative of Hikaru, his parents has passed and afterwards Sai is staying with Shindou Heihachi (who must be very happy to get someone to play go with).

Ps: Sai came first, and then later the twins came. They first met when the twins are 9years old.

edit: Sai is 15 years old.

Just had the idea so decided to try and write it. English is not my 1st language and this is my 1st fanfic. Sorry if I make mistakes here and there. The storyline won't follow the manga, although I might add portions of the story here. No pairings intended. I like Hikaru and Akira but I love their rivalry above anything else XD

Chapter 1: First Meeting

"Listen to grandpa and grandma while we are away, okay? Can you do that for me, boys?"

A woman said while pressing the bell on the door in front of them. The bell's sound echoing inside of the house while they wait for someone to open the door.

"Heh, chill out, mom. I can take care of myself just fine." one of the boys, Hikaru, answered with a smile and smug expression on his face.

"Don't worry, mother. I'll keep an eye on him so that he won't do anything stupid." The other boy said with reassuring tone to his mother.

"What do you mean by anything stupid, Aki?"

"What you always do, Karu."

"I don't!"

"Yes you do."

"What!"

"When you picked a fight with one of the upperclassmen, they went to me because they thought it was me. I had to clean up the mess after that. And then during the time when we went to the shopping mall and you somehow gotten yourself lost in the middle of Food Court. There's also that incident when you-"

"Argh! Shut up already! You're so noisy, hideaki!"
He said while covering his ears, obviously not wanting to hear anything from his brother while the other seems to have so many things to say about how many times Hikaru ended up getting himself in trouble and somehow managed to drag him along and making him to tidy things up after him.

"The noisy one is you, hikaru. And call me aniki, I am older than you."

"Only by a few minutes!"

"That still counts."

They continue to argue with each other even though one is shouting loudly like an angered lion while the other one is answering calmly like a teacher explaining why birds can fly to his student. Their mother, Shindou Mitsuko sighed and wondered if it's really a good thing to leave them with their grandparents. Maybe she should rethink the decision? But there's no turning back as she already promised that she will go after her husband and accompany him on his business trip after she made sure that their children are safe with her in-laws.

Just as Mitsuko turned towards her children and wanted to open her mouth to say something to calm the bickering children, the door that they've been waiting to be opened finally opens, revealing an elderly man coming from inside to greet them.

"Mitsuko! I thought you are supposed to come tomorrow!" Shindou heihachi said with a bit of surprise in his voice although anyone can see that he's really happy to see both of his grandchildren that he haven't see for a while from the big smile on his face.

Mitsuko turned to face Heihachi and smiles to her father in-law.

"Yes, father. The flight has been moved forward to this afternoon so I had no choice but to bring them here today instead of tomorrow. I am sorry for troubling you because of my sudden arrival."
She bows politely while explaining the reason of why she's been there quite early. It's only 8AM in the morning.

"It's no trouble at all. I am happy to see both of them again after all these times. Right?" Heihachi said while grinning widely at his grandchildren who already stopped arguing and just staring at him. Mitsuko gestured to both boys to greet Heihachi and so they did.

"Yo! Jii-chan!"

"How are you, Ojii-san?"

It's quite funny to see how different lines are said by two similar looking faces. But that's just the way they are. Even though Hideaki and Hikaru are twins, the only things that confirm they are twins are their faces. Apart from that, their personality is completely opposite of each other. Hideaki is a polite, well-mannered, and prefer staying indoors to read books while Hikaru is a brash, active, who likes playing soccer. It's a wonder how these boys can be similar yet so different at the same time.

"Hikaru! Be more polite to your grandpa!" her mother said with embarrassed face while looking at Heihachi to see his reaction on Hikaru's greetings. To her surprise, heihachi just laughed and patted both of the boys' heads.

"It's okay, it's okay. I get the feeling this place will get livelier now that the two of you are here. I bet grandma will think so too." he said with a happy smile on his face.

Mitsuko just smiled hearing what Heihachi just said. Probably it's not such a bad idea to leave their boys with them after all… Both Heihachi and his wife have been saying that they have been dying to see their children again. The last time they saw them was a few months ago during Heihachi's birthday. After looking at her watch, she decided that it's time for her to go back and prepares some more stuffs before flying off in a few hours so she hugged her children for one last time.

"I am going now. You two be good boys and listen to Grandpa and Grandma, okay?" she said with a bit of shaky voice and teary eyes when she finally let them out of her embrace.

"uh-huh. No worries." said Hikaru with a smile, not wanting to make her mother worry while Hideaki just nods reassuringly at her mother. She just smiled, trying to hold her tears. After saying a few more words to Heihachi, she proceeds to ride the taxi that has been waiting for her. They stayed outside, looking at the taxi until it's finally out of their sight.

"Let's go inside. Grandma must be waiting for us."

"Jii-chan, I want that room near that sakura tree!" shouted Hikaru to his grandfather while running towards the said room and opens the sliding door right away before he can say anything.

A figure with long hair sitting on the chair near the window seemed to be surprised at the sudden appearance of Hikaru into the room but he quickly gained his composure and slowly standing up to greet them.

"My name is Fujiwara Sai. Nice to meet you, Aki-chan, Karu-chan. Heihachi-san has told me so many things about both of you." said Sai with a soft smile to the twins

A/N:

Hikaru's twin is named Hideaki. Yup, he's an OC, personality wise, he's opposite of hikaru, a bit of Akira maybe. I wonder if any of you thinks I made Akira as Hikaru's twin when Hikaru said Aki? Lol. I just want him to have a name with 'light' in it like Hikaru.

Reviews will be nice to help me get better in writing : D

Not sure what category to put. Next chapter is fast forward to the point where Sai and the twins already getting along~
