I haven't watched/read Nabari in a while, unfortunately; so forgive me if people are out of character. I'm going off memory here. :)
Yukimi was cold when he woke up. He lay there for a second, remembering why he was on the kitchen floor instead of his bed. Yoite had tugged all the blankets onto him, leaving only a sliver of a quilt left for Yukimi to use. The latter wretched the quilt from the boy and threw it around himself, getting to his feet. Yukimi turned on the gas stove, rubbing his hands over it for a moment.
After two calls to the landlord, Yukimi still wasn't able to get ahold of him. With rising anger, he found a phone-book under a pile of old papers and called someone to come fix the heater.
He finally got in touch with the landlord after the maintenance people showed up. He sent them down to fix the heating unit, and shut the door. Yoite was still sleeping and Yukimi saw no reason to wake him. He sat at his computer with the quilt wrapped around his shoulders, typing up the rough draft of his next article.
The maintence men came back to check that the thermostat was working and to get their money. Yukimi thanked them and sent them on their way, hearing the system kick on and start spewing heated air from the vents. He made sure the stove was shut off and went back to work.
There was a knock on the door around noon. Yukimi opened it to find a brat standing outside with a scarf wrapped lazily around his neck and blue gloves on his hands; Miharu.
"Is Yoite here?"
Yukimi sighed and let the kid in, shutting out the cold. Yoite had woken up a few hours ago and was sitting in front of the couch.
"Hey, Miharu," he looked up as the boy came into the room.
"I was going to see if you wanted to go to the park. It's not too cold if you wear a jacket," Miharu loosened the scarf around his neck.
Yoite pulled his knees to his chest and buried his face in them, "I don't wanna go outside."
"We had a bad experience with the cold last night," Yukimi spun around in his chair, "The heater broke it wasn't fixed until late this morning."
"Oh. Then we'll just stay here," Miharu settled down on the floor next to Yoite.
"Yes you can stay in my house, thanks for asking," Yukimi spun back to his computer and continued typing.
After half an hour of silence, Yukimi slowly turned around, "Frankly, I don't care if you come over here, brat. But I do have a problem with you bringing a second air of death and despair into my house. This atmosphere is depressing me. You two are like vacuums that suck the life outta everything."
Yoite glared at him.
"You know its true, Yoite. Now, find something to do or go somewhere else."
Miharu rose to his feet, tugging Yoite up beside him. They disappeared into the kitchen and a commotion of pots and pans rattled through the air.
Yukimi left them alone while Miharu started cooking something on the stove. It smelled good, and Yukimi's rumbling stomach reminded him that he skipped lunch. He wandered in once he got to a stopping point in his article. The two were sitting at the table eating in a comfortable silence. Yukimi grabbed a plate of food and leaned against the counter while he ate, "This is really good, Rokujo."
"Thanks."
Just then there was a knock at the door, "Who the hell could that be?"
"Is Miharu here?" Raimei demanded. Her face was flushed as she gasped for air.
Yukimi glared at the blonde-haired girl standing at his doorstep, "Why are you out of breath?"
"Because I ran here, dummy. Now is he here or not?"
"Yeah, but-"
Raimei charged in the door, "Miharu!"
"What?"
"What do you mean, what!? Tobari-sensei was looking for you and you wouldn't answer your phone! Kouichi and I have been trying to find you all day!"
Yukimi stepped into the kitchen as Raimei whipped out her cellphone and dialed a number. "I found Miharu. He's with Yoite at that spiky-haired Kairoshou guy's apartment."
"Who're you calling spiky-haired guy?"
"Yes, Kouichi. Okay, bye," Raimei whirled on Miharu, "I get that you don't care, but we do, okay? You went missing and we couldn't find you!"
"Sorry."
"But you're not sorry!" She pulled at her hair, "Ugh!" She stomped into the other room.
Yukimi looked at the two boys then followed Raimei into the living room.
"It's so annoying! He doesn't care about anything!" She said in a lower tone so only Yukimi could hear.
"He cares about Yoite," Yukimi glanced at them.
"I know," she sighed, sliding down the wall to the floor, "He cares about little birds and bugs and plants but..."
"Stop stressing so much. He's worried too, he just expresses it differently."
"How do you know that?"
Yukimi scoffed, "Because he's always here. I can't get rid of him." They sat for a moment, then Yukimi asked, "Why do you care so much?"
"What?"
"About him," he jerked his thumb back at Miharu, "Why do you care so much about him?"
Raimei blushed, "Because he has the Shinrabansho. He's important to the Nabari world. I don't want him to use it for something stupid."
"Like for Yoite?"
Raimei laid her chin on her arms, her knees pulled up to her chest, "I don't know. I just... Don't want anything bad to happen."
Yukimi pushed himself off the wall and went back to his chair, "You can't stop the storm from coming."
Raimei buried her face in her knees.
Maybe one more chapter?
