The outskirts of Kuoh were quieter than the city proper.
Not empty — just thinned out, the way things thin out at the edges of anything. Buildings giving way to open ground, patches of scrub and low trees sitting in the gap between what the city was and what it was still deciding to become. Riku came out here sometimes when his head needed space that the manor's walls couldn't provide. Not to train. Just to walk.
He was doing that now. The morning was cold and clear, winter sitting lightly on everything, his breath visible in the air ahead of him. He kept his energy pulled inward the way it had become habit — small, quiet, unremarkable. The city had things in it that paid attention to energy signatures. He'd known that since he was six.
He heard the other boy before he saw him.
Sharp exhales. Rhythmic, controlled, the specific cadence of someone pushing through something physical at the outer edge of what they could manage. Too deliberate for distress. Too consistent for play.
Riku slowed and listened. Then stepped off the path.
--DxD--
He was behind a cluster of trees set back from the open ground. Big for his age — not in the soft way of children who had simply grown quickly, but in the way of someone whose body had been asked to do serious things and had started answering that call. Shirtless despite the cold. Hands wrapped in cloth that had been rewrapped so many times it had lost its original color. He was hitting a thick tree trunk with the focused repetition of someone who had been doing this for a long time and intended to keep doing it.
No technique Riku could identify. No system, no form. Just the absolute commitment to impact, over and over, with the kind of silent intensity that lived on the other side of anger after all the noise had burned away.
His knuckles were bleeding through the cloth.
But there was something else underneath the raw physicality of it — something Riku's Mana Awareness caught at the edges, subtle and unformed, like heat coming off stone that had been sitting in the sun all day. Not mana. Something different. Something that felt closer to the body itself than any energy technique he'd encountered. It flickered in and out with each impact, brightest in the moments of maximum force, like it was trying to find a shape it didn't have a name for yet.
Riku filed it. Watched for a moment longer. Then stepped out from the trees.
The boy stopped mid-swing and turned with a speed that wasn't a child's speed. His eyes found Riku immediately — dark, carrying something heavy underneath the surface — and for a moment neither of them said anything.
The boy's eyes moved over him. Taking stock. "Human," he said. Not an insult. Just a fact being noted.
"Yes," Riku said.
A pause. "You were watching."
"You were making noise."
Something shifted in the boy's expression. The recalibration of someone who had expected a different response and was deciding what to do with the one he'd gotten. He turned back to the tree. Hit it twice more. Stopped and looked at his hands with the detached assessment of someone evaluating equipment.
"What do you want," he said. The phrasing of someone who had learned that people generally wanted something.
"I was walking," Riku said. "You were here."
The boy looked at him again. Longer this time. "You're not scared."
"Should I be?"
A pause. Something moved behind his eyes — briefly younger, briefly unguarded, before it went back under. "Most humans would be."
Riku considered that. "Most humans can't tell what you are," he said. "I can. I'm still not scared. Those are different problems."
The boy was quiet for a long moment. Then he sat down on a root at the base of the tree and began unwrapping one hand with the methodical patience of someone doing necessary maintenance.
"Sairaorg," he said.
"Riku."
--DxD--
They sat in silence for a while. Riku had learned early that silence didn't need filling, and Sairaorg had the quality of someone for whom silence was simply the default state between useful things.
Riku looked at the tree. The bark where Sairaorg had been hitting it was deeply scored, the damage going back weeks at least judging by the weathering on the older marks. This wasn't a morning's work. This was a project.
"Your form is wrong," Riku said.
Sairaorg looked at him. The expression of someone deciding whether to be offended.
"You're hitting with the knuckle line parallel to the surface," Riku said. "First two knuckles should lead, body weight behind them, not just arm. You'd hit harder and it wouldn't cost you as much."
A long silence.
"You're nine," Sairaorg said.
"My dad has been teaching me since I could stand up properly," Riku said. "I'm not guessing."
Sairaorg looked at him for another moment. Then he stood, faced the tree, adjusted his hand position the way Riku had described. Hit it once. Stopped. Hit it again. The sound was different — heavier, more concentrated, the impact going somewhere instead of spreading across the surface.
He looked at his hand. At the tree. Back at Riku.
He didn't say anything. But he adjusted his stance slightly and hit it again, and this time Riku could see him actually feeling for it — not just executing the correction but trying to understand why it worked.
That flicker of something underneath the impact again. Stronger this time. More concentrated, following the correction like it had been waiting for the right shape to pour itself into.
Something settled quietly in Riku's chest.

They stayed out there for two hours.
Riku corrected his form three more times — weight distribution on the follow through, shoulder alignment, how to plant his feet so the ground worked with him rather than just bearing his weight. Sairaorg took each correction with the focused attention of someone who had been waiting for exactly this without knowing it. He absorbed it and applied it and kept going with the commitment of someone who did not do anything halfway.
He never asked for more. He just used what he was given.
Around midday Riku sat on the root Sairaorg had vacated and watched him work through the adjusted form. The difference was already visible — cleaner impact, less scattered energy, the hits landing with a concentration they hadn't had two hours ago. And the flicker underneath was steadier now. Not consistent yet. But present in a way it hadn't been at the start.
Riku didn't mention it. Not yet. But he noted it with the part of him that noted everything, and filed it next to the question it was going to eventually require an answer for.
"You live out here," he said eventually.
"For now."
"Alone."
The pause answered the question without words.
Riku thought about the weeks of marks in the tree bark. The cloth rewrapped so many times it had no color left. A boy with no one pulling him back to the Underworld and nowhere else to be.
"You can come to the manor," he said. "If you want. Tomorrow."
Sairaorg stopped mid-swing. Turned slowly. The look of someone who had stopped expecting things to be offered without a price attached. "Why."
"Better training space than a tree," Riku said. "And my dad knows more about hitting things than I do."
A long silence. Sairaorg looked at him with the heaviness that sat permanently behind his eyes — the weight of someone who had been given enough reasons to distrust offers that didn't come with a cost attached.
"Your family knows what I am," he said.
"Yes," Riku said. "They won't care."
Another silence. Longer.
"I'll be here in the morning," Sairaorg said finally. The phrasing of someone not quite accepting but not quite refusing either.
"I'll come get you," Riku said.
--DxD--
He was back at the manor before dinner.
His mother was in the library running energy calculations, her attention moving across something Riku couldn't see. She looked up when he came in and read his face before he said a word.
"You found something," she said.
"Someone," Riku said. He sat across from her. "On the outskirts. Devil, young, training alone." A pause. "Bael clan. Exiled."
His mother set her brush down. The particular stillness that meant she was running a calculation he wasn't seeing all of. "Sairaorg Bael," she said.
He looked at her. "You knew he was there."
"I sensed something on the outskirts two weeks ago. I didn't investigate." She folded her hands on the table. "His energy isn't a threat."
"No," Riku agreed. "It isn't."
She looked at him with the expression that meant she'd already reached a conclusion and was waiting to see if he'd reach the same one. "You invited him to come tomorrow."
It wasn't a question. "Yes."
"Good." She picked up her brush. "Tell your dad at dinner."
--DxD--
Dinner was rice and miso and the particular quiet of an evening that hadn't decided what it was yet. Kairi was eating with the focused efficiency she brought to meals she approved of, occasionally offering commentary on the food that nobody had asked for and everyone found completely reasonable.
Riku waited until there was a natural pause.
"I met someone today," he said. "On the outskirts. His name is Sairaorg. He's a devil — Bael clan, exiled. Training alone out there." He kept his voice even. "I invited him to come tomorrow."
His dad set his chopsticks down. The deliberate pause of someone giving something their full attention. "Bael," he said.
"Yes."
"How old."
"Ten. Maybe eleven."
His dad was quiet for a moment. "Alone?"
"Yes."
His dad looked at his mother briefly — the look that wasn't words — and she gave the smallest nod, which meant she'd already told him what she'd sensed and they'd already had part of this conversation without Riku present.
"Kairi stays inside for the first visit," his dad said.
"No," Kairi said immediately, without looking up from her rice.
His dad looked at her.
She looked back at him with the expression of someone who had assessed the situation and found the restriction unwarranted. "I want to meet him."
"Kairi—"
"I'll be good," she said. Which from Kairi didn't mean quiet or unobtrusive. It meant she had decided to exercise restraint and was offering that as a concession.
His dad looked at her for a long moment. Then at Riku. Then back at his rice.
"She stays with you," he said to Riku.
"Always," Riku said.
Kairi returned to her dinner with the satisfaction of someone who had negotiated successfully and was gracious enough not to show it too much. Then she looked up at Riku with the directness she used when she had a question she'd already decided deserved an answer.
"What's he like?" she said.
Riku thought about it properly. "Serious," he said. "Strong. Hasn't had much to be okay about lately."
Kairi considered that with the gravity she gave things that mattered. "We can fix that," she said. Like it was obvious. Like it was simply a problem that had a solution and they were the solution.
Nobody argued with her.
--DxD--
That night Riku lay in the dark and thought about the flicker underneath Sairaorg's impacts. Steady in the moments of maximum force. Trying to find a shape it didn't have a name for yet.
He'd felt something adjacent to it once — his dad's energy in the early morning drills, sitting underneath the technique like bedrock. Not mana. Something older than mana. Something that came from the body itself rather than from any cultivation or training method.
He was going to ask his dad about it tomorrow.
Through the thread Kairi's presence was warm and settled and entirely decided, the way it got when she'd made up her mind about something and wasn't interested in reconsidering.
He closed his eyes.
Tomorrow his dad would meet Sairaorg and spar with him within the first hour because that was how his dad met people who mattered. Tomorrow Kairi would introduce herself with the complete confidence of someone who had never once considered the possibility that she might not be welcome.
Tomorrow something would begin that he was already certain was going to matter for a long time.
