I had an idea in my head where the siblings meet each other and so I decided to write this. Hope you like it :D

Rio and Ryoga were coming from school. She had a pretty good day at school. Shark on the other hand; well lets just say he had a rough day at school. When they were walking, Rio had an idea in her head.

"Oh Ryoga." she sang and touched his shoulder. He looked at her impassively.

"What is it Rio?"

"Let's go to the pet store." She told him happily.

He stopped walking and Rio did to.

"No Rio." he said bluntly. She frowned at his reply.

"Come on, it will cheer you up. Plus I know you like to look at fish." She smirked at the last statement.

More like eating them. Ryoga thought. With Rio's idea he thought maybe it wasn't such a bad idea. Shark then looked at her.

"Fine." He replied and sighed.

"Great!" They both started to walk there.

Haruto and Katio were outside too along with Orbital 7.

"Wow, brother that was fun!" Haruto exclaimed.

Kaito chuckled in response. They just finished food shopping and for the first time, Haruto actually went outside with his brother.

"Alright, let's go home Haruto."

He took the little one's hand and were walking back home. Haruto looked behind him and saw someone that look like someone he saw before. That person was entering into the pet store. He was curious so he wanted to go in their too.

"Brother, can we go to the pet store?" The younger boy asked happily.

Kaito hesitated on the question. He thought for a minute. He was alright with pets but didn't want to buy one.

"Well-L-lord Haruto…" Orbital 7 started to say but Kaito then cut him off.

"Sure…but let's look at them, okay?" He said not wanting to make him upset. Hart nodded. They both turned around and started to walk over there. When they got in the store, Haruto saw the person that he saw earlier. Kaito on the other hand saw Shark in a different direction.

"Brother, I'll be over there." He said and looked up at his brother.

"Sure. Orbital go with him." Katio commanded and started to approach Shark.

"U-understood!"

Shark was looking at a tank of fishes. His hands were on the tank and looked at them in a serious manner.

"This fish is really big, compare to the others."

"Having fun looking at fish, Shark?" He gasped, turned around and saw Kaito.

He was standing with a hand on his hip and smirked. Shark changed from surprised to anger with his teeth showing.

"Kaito. What are…you doing here?" Shark looked away with his eyes closed, calming down a bit.

"My brother wanted to come here." He said and sighed. They both stayed silent were a silent for a moment.

"I'm going to find my brother."

"Whatever." He replied not caring and continued to look at other fish.

With Haruto and Orbital 7, he saw the person looking at dogs. It was Rio.

"They both looked the said referring to Shark and Rio.

"W-who Lord Haruto?." The robot replied asked

"Huh, who's there?" She asked and was going to turn around. He said it out loud and when she questioned, it made him alert. He didn't expect her to notice him or talk to him so he hid behind Orbital 7.

"L-lord Haruto!"

"What is a robot like you doing here?" She touched Orbital 7 shoulders.

I have a n-name you k-know! Orbital 7." He was irritated and turned around.

That wasn't good for Haruto when Orbital 7 turned around because now she saw him on top of him. Rio chuckled and went close to Haruto.

"You don't have to hide, I'm not going to hurt you." she told him. He then let go of Orbital and looked at her. She looked at him with her eyes closed with a genuine smile to him.

This person is like the girl who hangs out with that donkey 24/7. Orbital was referring Yuma as the donkey and the girl Kotori.

"What's your name?" she bend down and was going to touch his shoulder but then felt a hold on her hand. Haruto, Rio, and Orbital 7 saw it was Kaito. When she was realized it was him, she blushed.

"M-master Kaito!"

"Get away from my brother."

The little's boy older brother is Kaito! Rio thought to herself and tried to say something."Your K-Kaito…" she only managed to say at this moment.

Oh great she's a fan girl. He thought to himself.

All of sudden he felt a touch on his shoulder. Kaito turned around and saw it was Shark.

"Let go of my sister, pal." Shark told him firmly.

"You're related to this punk?!" Orbital 7 asked surprised. Ryoga looked at the robot angrily with his hands in a fist.

That's why they look alike. Haruto thought.

Kaito looked back at his hand and saw he was still holding her hand, he gasped and then immediately let go. Ryoga has a sister? He questioned in his mind.

"Uh…well your sister was bothering Haruto." He gently pulled his brother close to him.

"Brother, she said she wasn't going to hurt me. Please don't be mad at her." He said innocently. Kaito saw his brother with a frown so his expression softens.

"You don't have to be a jerk to him!" She got the strength to speak and crossed her arms, talking to Shark.

"Who I'm doing this for?" he asked annoyed. While the two were having an argument, Kaito, Haruto, and Orbital 7 were just watching them.

"So those guys are twins?" Kaito's brother asked.

"Yes they are lord Haruto"

"Stop it, both of you." Katio cut in. When he said, Shark realized his hand was still on his shoulder.

He moved it away immediately and his face was red. All of them were just standing there and thinking of each other. Haruto and Orbital decided to go to another section of animals to look at.

They are siblings and twins…unbelievable. Kaito thought surprised.

I can't believe I was still holding his shoulder! Shark thought angrily.

I can't believe Kaito touched my hand! Rio thought happy.

Shark then decided to say something.

"I'm outta here, lets go home Rio." He said walking away.

"It was nice meeting you, Kaito. By the way my name is Rio."

"Sorry about before, Rio."

"Its alright, Kaito. You were just trying to protect Haruto"

He just slightly smiled as his response.

"Rio, come on already!" Ryoga told her annoyed. She then followed him but then stopped when she saw Haruto with an animal in his hand.

"Cat!" he said happily and hold it up to her face.

"Aah!" she yelled and ran to Ryoga. Haruto stepped back because she screamed which he never expected her to do. Shark sighed and they then both left the place.

That was awesome. Rio thought.

What a day. Shark thought to himself tiredly.
