The silence Ren found when he closed the door to his own room was not the same old silence of the Uchiha compound. Back then, silence meant discipline, routine, the feeling that everything was in its place. Now, silence had texture. It had weight.
He sat down on the floor again, just like he had the day before, but he didn't seek that same state of connection; that wasn't what his body was asking for now. What he felt was simpler, and precisely because of that, harder to swallow: he remembered the exact moment when his vision went dark, the sound of his own blood pounding in his ears, Ino's scream cutting through the forest like a blade, and the humiliating sensation of losing control of his own body at the exact moment when control was the only thing separating life from death.
On the mission, he hadn't fainted out of cowardice. He knew that. Still, the truth didn't soften the fact. In the real world, the reason didn't matter as much as the result.
Ren opened his eyes and stared at his hands. There was no trembling, no visible weakness. His abdomen still pulled when he breathed too deeply, a constant reminder of the wound and the price he had paid for running toward Ino without hesitation.
He didn't regret that choice. If necessary, he would do it again. That was exactly the problem: he would do it again, and if he fainted again, someone could die.
Maybe Ino herself. Maybe Shikamaru. Maybe an innocent. Maybe even him, without realizing when the line had been crossed. He didn't want to be the kind of shinobi who lost to his own body. And worse than that, he didn't want to be the kind of shinobi who lost to his own mind.
That was when the memory of the bell test came back, not as nostalgia, but as contrast.
That day, Asuma had been provocative, deliberately lazy, almost playful. He had left calculated openings, spoken like someone giving a lesson, attacked and retreated without letting the air become too heavy.
Ren remembered the sound of metal when he managed to snatch one of the bells, and he remembered Asuma's look at that moment: attentive, yes, but still… light. It was a "game" with invisible rules. A simulation of danger, but without the danger itself. And Ren had believed, back then, that understanding patterns and being efficient was enough to be ready.
Now he knew the bell test had been exactly that: a test. A step. A warning.
Ren stood up slowly, feeling the sharp pain in his abdomen like a hand pulling him back toward the bed. He ignored it. Not with blind stubbornness, but with cold resolve. If he waited for the pain to disappear completely, he would always be waiting for something. He grabbed his headband, tied it around his forehead, took a deep breath, and left.
The village seemed the same as always. Children ran around, vendors shouted, people laughed as if sound itself were not a luxury.
Ren passed through everything as if walking through water: he felt it, but didn't let himself be carried by it. He didn't go to Ino's house, even though part of him wanted to look at her window just to make sure she was okay. He didn't go to Shikamaru, because Shikamaru didn't like visitors when he was resting. He went to the place that made sense, the place where answers were always harsher than necessary, but almost always true.
The training field was empty when he arrived, but not silent. There was wind, there were leaves, there was the feeling of open space. Ren stood still for a moment, sensing the difference between the "living" silence of the village and the "alert" silence of a road about to turn into an ambush. He heard footsteps behind him before he even saw them, and he didn't need the Sharingan to recognize the rhythm.
Asuma appeared with a cigarette in his mouth, hands in his pockets, as if he were just taking a walk. But Ren knew that kind of posture. It was the same posture from before danger, the same posture of someone who looks relaxed because they don't need to prove anything to anyone.
"You should be resting," Asuma said, without exaggerated greetings.
"I've rested enough," Ren replied.
Asuma raised an eyebrow, glancing quickly at Ren's abdomen, as if he could see through the clothes. "The medic would disagree with that statement."
Ren kept his gaze steady. "The medic won't help me stop this from happening again."
The cigarette stayed between Asuma's lips for a second longer than normal. He released the smoke slowly, as if deciding whether Ren deserved a scolding or honesty. "So that's it."
Ren didn't look away. "I want to gain experience in life-or-death combat."
Asuma let out a short, humorless laugh and pointed with his chin to the center of the field. "You think that's something you ask like this, as if you're asking for extra training?"
"I think it's something you ask while you still have time," Ren answered.
The silence between them was different from the silence in Ren's room. There, it was the silence of a jōnin deciding whether truth was worth more than peace. Asuma took the cigarette out of his mouth and crushed it on the ground, carefully, as if that gesture itself were a line being drawn.
"In the bell test," Asuma began, "I was testing you. Your minds, teamwork, instincts. I was in control the whole time. Even when it didn't look like it."
He took two steps forward, stopping at a distance that was safe, but not comfortable. "On the road… I was also in control, until I wasn't anymore. And you felt the difference."
Ren swallowed, hating the way his body reacted. "I felt it."
"You felt it and still blacked out," Asuma said directly, without unnecessary cruelty. "And I'm not saying this to put you down. I'm saying it because that's exactly why you came here."
Ren clenched his fingers. "I don't want that to happen again."
"Then be clear," Asuma replied. "Do you want to learn how to kill?"
Ren didn't react the way he would have months ago. There was no outrage, no dramatic moral retreat. There was only heavy honesty. "I've already killed."
Asuma nodded, like someone confirming what he already knew. "I saw it. And I saw that you didn't do it for pleasure. You did it because it was necessary." He looked into Ren's eyes with a seriousness that hadn't existed before. "But necessity is not a word that protects you from consequences. And if you want experience, you don't just want technique. You want mental condition. You want to stay standing when the world tries to knock you down from the inside."
Ren took a deep breath. "Yes."
Asuma stayed silent for a few more seconds, and Ren realized that wasn't indecision; it was responsibility. A jōnin doesn't choose only what to teach. He chooses what to put inside a genin. He chooses the kind of scar that doesn't appear on the body.
"Alright," Asuma said at last. The word was simple, but heavy, like a gate opening. "I'll help you."
Ren didn't show visible relief, but something inside him unlocked. "How?"
Asuma raised two fingers. "Two parts."
Ren waited.
"The first part is here," Asuma continued. "Fights with me. But understand this: it's not the bell test. Back then, I was teaching. Now I'm going to pressure you for real. I won't kill you, because I'm not an idiot, but I'll fight like someone who could. I'll aim at points that make you understand what happens when you hesitate. I'll make you feel the difference between 'getting hit in training' and 'losing because you breathed wrong'."
Ren nodded, already feeling his abdomen protest just from imagining it.
"The second part," Asuma said, "is missions. Not missions to rescue cats from rooftops. Missions with real risk. And before you open your mouth, no, I'm not taking you to a massacre so you can 'get used to it'. That's not training, that's stupidity. But I will choose missions where combat is expected, where you'll have to read people who want to hurt you, and where you'll have to make decisions without time to meditate in the middle of it."
Ren felt his stomach tighten. Not from fear. From recognition. That was it. Exactly what he was asking for.
"And there's one condition," Asuma added.
Ren looked at him.
"You don't do this alone," Asuma said. "You're part of a team. If you want to stay standing, you stay standing for the team, not in spite of them. You'll train, and you'll train with them too. Ino and Shikamaru are part of this, each in their own way, because if you go into real combat and each of you is at a different pace, you die."
Ren thought about Ino holding his hand when his vision went dark. Thought about her scream. Thought about the fear on her face. "I understand."
Asuma gave a small, serious half-smile. "Good. Then we start now."
Ren blinked. "Now?"
"Now," Asuma replied, and there was no room for negotiation in the word. "If you want life or death, you start when you're not comfortable. Because in war, no one waits for you to be ready."
Ren took a deep breath and positioned himself in the field. He felt the sharp pain in his abdomen, adjusted his center of gravity, and kept his body as aligned as possible. Asuma took his hands out of his pockets and, for the first time since appearing, the air around him changed. It wasn't chakra exploding. It was intent. It was as if space itself understood that this was not a game.
"Rules," Asuma said, his voice firm. "You can use what you know. I'll hold back enough so you don't die, but not enough for you to feel safe. If you freeze, I'll take you down. If you faint, I'll leave you on the ground, and you'll wake up remembering the weight of that. Understood?"
Ren nodded and activated the Sharingan.
The world became sharp in a cruel way. Asuma didn't have the nervous haste of a common enemy, nor the hesitation of someone improvising. He was stable, and that was more frightening than speed. Ren saw micro-movements: the slight adjustment of the foot, the shoulder too relaxed to be normal, the hand ready to produce a blade in less time than a genin should be able to follow.
"Come," Asuma said.
Ren went.
He didn't attack with force, he attacked with precision, trying to create reading before damage. The first move was a kunai thrown to force Asuma to move his head; the second was Ren entering low from the side, trying to attack the leg to break his base. Asuma dodged as if he had already been there before, and Ren felt the first difference: in the bell test, Asuma dodged "to show". Now he dodged "to not be hit". It was minimal, economical, without theatrics. The counter came as punishment.
Asuma appeared in the space Ren thought was empty, and the impact of a short strike hit Ren's shoulder like a wall. It wasn't enough to break it, but it was enough to make his arm tingle and his body remember that joints exist.
Ren spun back and immediately used a short shunshin, trying to reposition and attack from behind. In the bell test, that would have forced Asuma to admit Ren was fast. Now, Asuma was simply waiting. Ren felt the wind change before he understood why, and a short, sharp chakra blade passed so close to his neck that the hair on his arms stood up.
Ren stopped for a fraction of a second, and in that instant his abdomen pulled. The pain flashed. His body wanted to protect the area, wanted to curl inward. Ren felt his mind slipping toward that dangerous place, that place where the world becomes distant and the body decides to shut down.
Asuma appeared in front of him and, with his free hand, gave a sharp tap in the center of Ren's chest, not to hurt, but to wake him up.
"Stop pulling away," Asuma said. "If you leave from here, you die."
Ren breathed, trying to pull air in like an anchor. He remembered the state of connection, remembered the world "passing through" him, and tried to use that not as mysticism, but as a tool: he felt the wind, felt the ground, felt his own weight. The pain in his abdomen was just information, not a command.
He moved again.
Ren advanced with a short sequence, using the Sharingan to read micro openings, trying to fit attacks into the minimal gaps between Asuma's movement and reaction. He managed to touch Asuma's arm once, then almost hit his side, and felt a spark of satisfaction… which died in the next instant, because Asuma didn't retreat like before. Asuma advanced.
The jōnin's pressure was like a tide. Ren felt that if he retreated too much, he would be swallowed; if he advanced too much, he would be cut. He chose the third option: he spun, lowered himself, and tried to use Asuma's own momentum against him, pulling him out of center. For one second, it worked. For one second, Asuma lost the perfect line.
And then the world proved that "one second" is not enough.
Asuma locked the movement halfway, as if his body had brakes, and his knee rose, hitting Ren's side with enough force to tear the air from his lungs. Ren felt his vision narrow. His abdomen screamed. His body almost gave in again.
Ren staggered, and Asuma was already behind him, ready to finish with a blow that, if real, would end it there. But the strike stopped one centimeter from the back of Ren's neck. Even so, the sensation was death. Ren's skin prickled all over, and he understood, without needing words, what it meant to hear "someone could have killed you".
"That's the point," Asuma said, and there was something almost hard in his voice. "You can't rely on courage to keep going. Courage is good, but it doesn't hold your body when it decides to shut down. You need to train until your instinct understands that fainting is not an option."
Ren stood still, breathing with difficulty, his chest rising and falling as if trying to pull life out of the air itself. He didn't fall. He didn't black out. The pain was there, but he was there too.
Asuma took a step back, lowering his weapon. "Again."
Ren lifted his gaze, the three tomoe spinning slowly. There was no anger. No wounded pride. There was resolve.
"Again," Ren repeated, and advanced.
And in that moment, the contrast became complete: in the bell test, the sound of metal had been victory in a game. There, the sound that mattered was Ren's own breathing continuing, despite everything, and the silent certainty that from that day on, training had changed its name.
It was no longer training.
It was preparation.
