I wrote this a couple of weeks ago but couldn't think of a title. Thank you to .QueenViolet. for thinking one up for me. ^_^; This was originally going to be a one-shot, but ended up as three chapters long. XD!
I like to think Ryutaro took Reiji in after the fall of Dark Nebula (As Reiji probably has no where else to go) and Tobio lives with them too since I like to think Tobio and Ryutaro started to become friends during their time in the DN.

Reiji watched as Ryutaro washed the dishes. It had been about five or six months since he started to live with Ryutaro, but he could still remember the day well.

Ginga had just defeated Ryuuga, all those who had their energy drained by L-Drago reclaimed it and woke up from their comas. As Ginga was congratulated by all his friends he had made on his journey, Ryutaro noticed that Reiji was looking around in confusion and appeared a little afraid of the crowd of happy people. So Ryutaro decided to approach Reiji, remembering from their Beybattle that Reiji had lived his life in the Dark Nebula, he had never even seen daylight until the day of Battle Bladers.

"Reiji?" Ryutaro spoke softly as the snake turned slowly to face him.
"What do you want?" He hissed, moving cautiously.
"You have nowhere to go, do you?" He replied.
Reiji shook his head. "I stay in the Dark Nebula building."
"Reiji, Daidoji is no more. You can't fend for yourself, I can tell."
"I don't understand. If I stay in my room, I will get food brought to me, someone will come to wash and clothe me." Reiji stepped forward, annoyance in the tone of his voice.
"No you won't, Daidoji is dead, I saw him on the way down here. None of his servants will come back to you since Daidoji is not paying them anymore. Live with me, I'll take care of you and give you what you need." Ryutaro pleaded, his kind heart made him worried for the serpent wielder, despite the harm that he had brought the fortune-teller.
"What? Reiji blinked. "Why would you want anything to do with me?"
"I told you, you can't fend for yourself. It doesn't matter to me what you did in the past, I want to help you."
"But I still don't get why you would want me." Reiji stated.
"I would be able to teach you things you don't understand like love and kindness." Ryutaro put out his hand.
"You know you will be better off with me, even though you won't realise it yet."

Reiji looked unsure, staring and blinking at the other boy's hand. Slowly his own hand moved towards the other, this was the first time he had ever made his own decision in his life.

"...Ok." Reiji took Ryutaro's hand, who shook it.
"I'm glad." Ryutaro smiled warmly, giving Reiji a sensation that he did not understand, but enjoyed nonetheless.

After Ryutaro led Reiji to his new home, they came across Tobio on the way, who was grumbling about have to go to his home. Kind-hearted Ryutaro offered Tobio the opportunity to live in his house, as long as he had permission from his parents. Tobio agreed and they took a detour to Tobio's, once the sniper came back and told the fortune-teller his parents approved, they all went to Ryutaro's house. Both Tobio and Reiji were amazed by it's size. Reiji was used to a spacious basement with screens, while Tobio was used to an apartment with quite a few rooms, overall much larger than this one room Ryutaro lived in. It took both the redhead and blonde some time to get used to their new living arrangements, especially sleeping arrangements for Tobio, since Reiji didn't understand the problem with three guys sleeping near each other in the width of the house.

While Reiji continued to watch Ryutaro, Tobio entered the house, who'd just been sniping. The blonde put his carrier case into a cupboard and sat adjacent to the redhead.

"Hello Tobio." Ryutaro spoke, not looking away from his work.
"Hi." Tobio mumbled.
"Did you have fun?" The bluenette asked politely.
"Yeah..." Tobio sighed, never one to talk much.
"Oh good." Ryutaro smiled to himslef, glad that his friend had enjoyed himself.

Tobio joined Reiji in watching Ryutaro, seeing the fortune-teller do housework was somewhat fascinating. For Reiji, who was always curious, he would often watch Ryutaro do stuff as Tobio only did it occasionally. Unlike Reiji, Tobio did not pay much attention to Ryutaro at first, it took him a while to realise that he began to start noticing things the bluenette did, completely aware when the two began to live together with Reiji. Reiji took little notice of the blonde, while Tobio took little notice of the redhead.

Tobio looked over to Reiji to see what he was doing and as he often noticed the redhead doing, he was watching Ryutaro. Tobio began to glare at the other boy whose eyes did not move from the bluenette. As the sound of a plate clapped on top of another, Tobio blinked and shifted his focus onto Ryutaro, who had just finished the washing up and was now drying his hands. After that, Ryutaro turned around and leaned on the counter, smiling at the two boys sat on the floor.

"So what would you two like for dinner tonight?" He asked.
"Pizza." Tobio answered automatically.
"Ok then, is that ok with you Reiji?"

Reiji nodded and Ryutaro stood up straight.

"Right, so shall I make it or should I get a takeout somewhere?" Ryutaro asked.
"I like it best when Ryutaro makes it." Reiji blinked.
"...Me too..." Tobio mumbled with a tiny blush.
"Tobio?" Ryutaro looked at the blonde, not hearing his utterance.
"Sure, whatever." Tobio replied, acting like he didn't care who made the pizza, just as long as he got some today.
"And what would you two like on the pizza?" Ryutaro looked at the other two, unsure if they would be able to agree on something, since they had different tastes.
"I'll see when we're at the supermarket." Tobio told him.
"I'm not sure either." Reiji replied.
"Ok then, I just hope it won't cost too much" Ryutaro smiled, he was satisfied with that, he might be able to avoid arguments by reminding them that their money was limited.

The three of them left the house together and went to the supermarket. Ryutaro went to pick up a basket, but Tobio beat him to it.

"Thank you Tobio." Ryutaro blinked, surprised by the blonde's kindness, he held out his hand to take the basket.
Tobio shook his head. "I'll carry it." He told the bluenette.
"That's unusually thoughtful of you." He smiled, making the blonde look away and blush a tiny bit.
"I can be helpful...When I want to."

Ryutaro giggled at his statement, while Reiji hissed, making the blonde glare at him. Noticing the hiss made Ryutaro smile gently at the redhead.

"Is something the matter Reiji?"
"I want to help too." Reiji replied, not wanting to say he was feeling a little jealous and left out.
"Well, can you place the ingredients into the basket?"

This made Tobio mumble to himself as Reiji nodded.

"What's wrong now Tobio?" Ryutaro sighed, feeling like the other two had been more tense lately.
"Nothing." Tobio answered back.
"Ok...Let's go and get those ingredients then." Ryutaro smiled at them both before turning around and walking.

The blonde and redhead followed the bluenette.
