Almost two months had passed, and during that time, a few things had happened.
Asuma's funeral had taken place, and the village took nearly a full month to recover from the shock caused by the Hokage's son's death. It wasn't just sadness. It was the kind of impact that changes the way people walk through the streets, how they lower their voices at the corners, how they avoid looking too long at the Hokage Tower, as if facing it meant fully accepting that it was real.
Ren noticed it in details almost no one talked about. The silence in houses that once had laughter. The lack of energy even in the simplest missions. The weight on the shoulders of jounin who usually seemed untouchable. The constant feeling that the entire village was breathing more slowly, trying not to collapse from the inside.
And in the middle of all that, there were Ino and Shikamaru.
Ino recovered within a week. Shikamaru took five. Ren remembered his face, still pale, when he started walking without support again. He remembered the way the ponytailed boy pretended everything was normal, even though his eyes betrayed that something had changed. *He came back… but not the same.* And maybe no one ever came back the same after going through that kind of night.
Given the situation, Ren didn't go on any missions during that time and used the opportunity to undergo intensive training. It wasn't a dramatic decision, nor a promise made to the wind. It was pure logic. The village was shaken, the flow of missions had been interrupted, and he knew that if he stayed idle, his mind would fill the empty space with things he didn't want to face.
So he trained.
He trained until his muscles learned to respond without needing to be asked twice. He trained until his breathing became steady even when his chest burned. He trained until his hands were marked with small cuts—and those cuts vanished faster than they should have.
His strength improved during that period, and his control over Mugenkoku grew sharper, along with a physical improvement thanks to Saisei. Saisei was quiet, almost unfair. It didn't put on a show. It didn't make noise. It simply corrected. He could feel his body restoring itself after each session as if he were being granted a second chance every night. Minor wounds became memories. Sharp pain turned into discomfort. Exhaustion became a manageable weight. And that changed everything, because it meant more training time, more attempts, more room to make mistakes without paying the full price.
Mugenkoku, on the other hand, demanded a different kind of discipline.
The black substance responded to thought, but it wasn't simple. Wanting wasn't enough. He had to understand density, shape, the intention behind the shape. A blade that was too solid would shatter if the force was wrong. A shield that was too light would fall apart before fulfilling its purpose. And the more he tried to "dominate" it, the more he realized the point wasn't forcing obedience, but building a dialogue.
*It's not a tool.* *It's an extension.*
He spent days repeating the basics. Create, undo, create again. Turning the matter into thread, then plate, then needle. Testing resistance, varying thickness, feeling the boundary between what was possible and what was still just an idea. At times, the substance felt almost alive, as if it recognized the path. At others, it failed in an irritating way, without any obvious reason, forcing him to start over—breathe, and try again with less ego and more patience.
It was in that process, between repetition and persistence, that he discovered something new.
He realized Mugenkoku could incorporate chakra natures. He could sense that it would even be possible to fuse them, although for now, he could only use one nature at a time.
The first time he felt this, it wasn't an explosion of understanding. It was a detail. A small mistake that opened a door.
He had shaped a fragment of Mugenkoku into a short blade and tried to channel chakra through it, as if it were a real weapon. The flow didn't "run" the way it would through metal. It was absorbed. Mixed. The matter darkened further, the air around it changed, and for a fraction of a second, what he was holding felt like something else entirely.
He stopped immediately.
His heart beat faster—not from fear, but recognition. *That wasn't just reinforcement.*
He tried again, slowly, controlling the chakra more carefully, observing the reaction of the substance as if studying a rare phenomenon.
When he added a nature, the substance didn't just carry it. It became it, in its own way. As if Mugenkoku were a "medium" that accepted the information and rewrote the form.
*So it really works.*
And if it worked, that meant far too many possibilities for someone who already carried too much weight.
Each attempt gave him the same sensation: *the path is there.* And alongside it came another, more dangerous feeling: *what if I combine two?*
He couldn't yet. Every time he tried to force the fusion, the matter reacted unstably, as if the two natures were fighting for space. But he was certain it was possible. He could feel it, the same way someone knows a door exists even before opening it.
With that discovery, he created something that could be called a kekkei genkai:
Shin'enton.
The name came after several nights of thought. Not because he liked naming things, but because naming something meant acknowledging that it had an identity. And if it had an identity, he could organize it better in his mind, like a shelf where he stored things too dangerous to leave loose.
Shin'enton was the fusion of matter created through Mugenkoku with a chakra nature. And the sheer number of possibilities that combination allowed was enough to cause a headache.
He imagined uses beyond combat. Tools that didn't exist. Barriers that could change mid-impact. Threads that conducted lightning through themselves, cutting without needing a blade. Forms that dissolved and reappeared, confusing the eye, exploring that thin line between physicality and intent. The problem was exactly that: *too much*.
If he let his mind run freely, it turned into a labyrinth.
That was why he forced himself back to the basics. Create one thing. Test it. Understand it. Store it away. Only then move forward.
And when his body was exhausted and his mind finally quiet, he did what he had been doing more often lately.
Ren sat on the veranda of his house, looking at the afternoon sky. The sun was low, and the light had that warm hue that made everything feel slower. He liked that time of day. The village grew quieter, the wind gentler, and the shadows on the ground stretched longer, as if even time itself were slowing down to rest.
He leaned his back against the veranda pillar and let the air out slowly, feeling the weight of training spread through his body. His hands still carried that residue of chakra, as if the internal flow didn't shut off immediately. *I'm still whole.* It was a simple, almost silly thought—but a real one.
At that moment, he felt someone hugging him from behind and resting their face against his back. The touch was warm, familiar, and a smile formed on his face before he even thought to respond. He didn't need to turn around to know who it was.
"You're late today," he said softly.
"Sorry, the flower shop was really busy today, so I ended up running late," Ino replied, tightening her arms around him.
Ren didn't respond right away. He stayed there for a moment, taking in her scent, her presence, the way Ino fit against him as if that space had been made for her.
Then he shifted, pulling Ino onto his lap. He wrapped his left arm around her waist and used his right to guide her head to rest against his chest. She didn't resist in the slightest. She simply gave in, as if it were obvious that this was where she belonged.
"You don't need to apologize for something like that," he said.
She made a soft humming sound, her face buried against his chest. Ren felt the faint vibration and, without realizing it, let his body relax further.
During that time, their relationship had progressed quickly—like a dam breaking and water rushing out at overwhelming speed. Their feelings, which had been held back for a long while, had finally spilled over.
Ren didn't know exactly when it stopped being "possible" and became real. Maybe it was at the hospital, when he saw her trying to be strong and failing. Maybe it was during the visits afterward, when Ino talked too much to fill the silence and he realized that, for the first time, his silence didn't scare someone. Or maybe it had been before that, in small moments he ignored because he was too busy trying to survive.
Either way, this was how it was now.
His personality had changed a little as well. Living with such a cheerful girl had made him slightly more open. Not open in the sense of talking about everything. But open enough to laugh without monitoring himself, to answer without calculating every word, to accept that his chest could feel lighter without that being a trap.
Ino lifted her face just enough to speak, still close to him.
"We need to stop by the Hokage's office today."
"Do you know why?" Ren asked.
"No. Shikamaru stopped by the flower shop with his father and said the Hokage wanted to talk to the three of us."
Ren fell silent for a moment, processing it. *The three of us.* That wasn't casual. It wasn't a "come by when you can." It was a summons, even if delivered gently.
"I see. Then let's—" Ren didn't even get to finish before Ino interrupted, pressing herself more firmly against him.
"Not now. Let's wait a few more minutes. I want to recharge my energy with you." She paused, then added, "And you're having dinner at my place today. Mom won't accept no for an answer."
Ren gave an ironic smile at her orders, but he agreed. He didn't have the energy to pretend resistance when the truth was simple: part of him wanted it. He wanted a normal dinner. He wanted a house where sadness didn't dominate every corner. He wanted to hear Ino talk endlessly while someone complained about the seasoning and, for a few minutes, everything felt human.
They stayed there a little longer, enjoying each other's presence. Ren listened to the wind, felt the warmth of her body, and let his mind slow down. *If I close my eyes now… I can forget for one second that the village bled.* It was tempting. But he didn't allow himself to sink into it.
He broke the silence at last.
"We should go now, or it'll start getting late."
Ino stood up reluctantly, pouting.
Ren laughed at her antics, took her hand, and said, "Let's go."
And so the two of them started walking together as the sunlight reflected around them. Ren felt her hand firm in his, as if Ino were anchoring something he hadn't even realized was trying to slip away. The path to the Hokage's office wasn't long, but in that moment, it felt like the kind of distance that separated two things: the small comfort of the veranda and the serious reality that always waited outside.
