Blood Demon in Demon Slayer - Chapter 9

Chapter 9 — Orders

He stopped when the forest stopped being something he was running through and started being somewhere he was standing in.

There wasn’t a clear moment of transition. It was more that, at some point, the burning in his left side had become loud enough that running stopped being a decision he was making and started being something his body was doing out of stubbornness, and then even the stubbornness ran out, and he found himself standing with his back against a tree and his hand pressed to his ribs and the sound of pursuit absent from everything the SEN was reading in any direction.

He had put enough distance between himself and the Wind Hashira that the gap had become a fact rather than a project.

He stood there for a while.

The forest here was different from Haruto’s mountain forest — thinner, younger, the trees spaced with less authority, the canopy not quite thick enough to produce the total darkness he’d been operating in. Enough cover to matter. Not enough to feel like shelter. But the sky above the gaps in the canopy was moving toward the specific shade of dark that meant the middle of the night rather than the beginning of it, and the SEN was reading nothing within its range that had the quality of trained pursuit, so.

Fine.

He slid down the tree until he was sitting at the roots, back against the bark, and he breathed carefully. The ribs had reached a consensus sometime in the last kilometre — three of them, negotiating terms with each other and with the surrounding tissue, the VIT grinding through the repair work with the focused resentment of a system being asked to do too much with too little. The cuts on his calf had closed. The shoulder was most of the way there. The ribs were going to take longer because ribs were structural and structure apparently required more from VIT than surface damage did.

He sat with the pain and didn’t fight it and waited for his head to clear.

‘Lucky’, he thought. The word arrived simply, without irony or qualification. Just: lucky. He was lucky to be sitting here. The Wind Hashira had clipped him twice with technique fragments — not full strikes, just the edges of movements that had been directed at someone else or not fully committed — and even those two partial contacts had done the damage he was currently paying off. A full Wind Breathing technique, aimed at him, sustained—

He stopped building that picture. It wasn’t useful.

What was useful was the lesson. He had learned something tonight that he hadn’t known before, or rather had known abstractly and now knew concretely, in the way that the body knew things: Hashira techniques did not require the sword to land. The wind from the blade was a weapon. The air the technique displaced was a weapon. The entire radius of a Wind Breathing form was dangerous, not just the edge that the sword defined, and he had AGI one hundred — he was about to have AGI one hundred — and it hadn’t been enough to guarantee he didn’t get hit.

He needed to think about that seriously.

After his ribs finished their meeting.

He opened the panel mostly to have something to look at while his body sorted itself out.

Six levels. He’d killed nine Demon Slayer Corps members and gained six levels from it, the EXP from each scaling with their level the way the EXP from the prison had scaled with theirs — level multiplied by a hundred, clean and consistent, the system applying the same math regardless of what he thought about the math.

He thought about the math.

Level 37 meant he needed 741 EXP to reach Lv38. That was eight ordinary people. Eight. He had levelled from one to Lv13 on a single night’s feeding and from Lv22 to Lv31 on a prison floor, and now each individual level was asking for more than an entire prison floor had given him at the start. The curve was steepening. The levelling was slowing.

He had known this was coming — every experience-based progression system in every game he’d ever played had the same shape, the early levels fast and generous, the later levels increasingly expensive. He hadn’t thought carefully about what it meant practically.

What it meant practically was that the passive-income period was over. The month of Haruto-digestion had been a gift, the equivalent of interest payments from an investment that had now paid out completely. From here, every level was a project.

He looked at the BP counter. Sixteen. Out of 370. The equivalent of walking on a nearly empty tank.

He looked at the Blood Soldier entry. Zero out of thirty-seven. Every soldier he’d built, every prisoner, every Corps member he’d just spent the night adding to the Blood Realm — gone. The Nichirin light in Masachika’s technique hadn’t just destroyed them, it had ‘ended’ them in the permanent way, the way sun ended things. He was starting over from nothing.

He looked at the free stats. Thirty, waiting.

He looked at VIT six and thought about three ribs and a VIT-level that made healing feel like watching paint dry in winter.

Here was the thing about VIT that he hadn’t understood properly when he’d made his first allocation: he’d assumed VIT was regeneration speed. He’d allocated accordingly — a little here, a minimum investment, enough to keep the system running without dedicating resources to it, because regeneration was the Regeneration ability’s job and he’d thought VIT was redundant.

It wasn’t redundant.

Regeneration speed — how fast a wound closed — was the Regeneration ability’s domain. That part he’d gotten right. But VIT handled something the Regeneration ability didn’t. ‘How many times’ you could heal. And underneath that, the foundational layer he’d missed entirely: how hard it was to wound you in the first place.

He’d read about it in the anime, seen it demonstrated in the fights he’d watched on a tablet screen in Room 214. Fourth Rank Demon — not a character he’d ever learned the name of, a reference, a calibration point — VIT so high that a Nichirin blade had struck his neck and the blade itself had broken. The sword had broken. Not the neck.

That was VIT.

His was six.

He pressed his hand against his ribs and felt the slow work of a Regeneration ability trying to do a job that VIT six was making difficult, and thought about the Wind Hashira’s technique, and thought about what a direct hit would have done to a body with six durability, and decided that the answer to that question was not a number he wanted to calculate precisely.

He sat with the free stats for a moment.

Thirty points. Nineteen into AGI. Eleven into SEN. That was the original plan, the continuation of the logic he’d been following since the cedar hollow — get AGI to a ceiling, then reassess, then build from there.

The ribs argued.

He thought about the argument the ribs were making. It was, he had to admit, coherent. AGI one hundred meant he was the fastest thing in this world except Muzan and people fighting at their absolute ceiling. He had that. He’d been using it. It had kept him alive in situations where being kept alive had been genuinely in question.

But it hadn’t prevented him from getting hurt. It had prevented him from getting ‘killed’, which was not the same thing. And in a world where he was going to encounter more Hashira — where he was going to encounter things like Sanemi Shinazugawa who cut his palm and whose blood had the audacity to be a trap — speed alone was not a complete defence.

The ribs made one final, pointed observation about the ongoing cost of VIT 6.

He acknowledged it. He did not change the allocation.

Without hesitation, 19 into AGI. 11 into SEN.

He felt the AGI change arrive — different this time from every previous allocation, the earlier ones each producing a clear, perceptible shift in how the world resolved. This one was subtler. Not because it was less, but because it was the completion of something rather than the extension of it. Like the last piece of a structure going in, the whole thing finding its final form and settling.

One hundred.

He moved his hand. Just that — lifted it from his ribs and moved it through the air in a simple arc, the kind of movement that required nothing. And the air moved around it differently. Not visibly. Not in any way that would have been detectable to anything watching. But he could feel the resistance of it, the way his body displaced the world around it, with a precision and a speed that had found a different relationship with physics than the one he’d been born with.

‘Muzan’, he thought. ‘And people with the Mark and inner world ability. That’s the company I’m keeping on this stat.’

He wasn’t sure whether that was impressive or terrifying.

Probably both. Probably both was the correct answer to most things in this world.

He pulled up the updated panel.

He looked at BC: 1 for a long time.

Not with guilt, exactly. With the particular weariness of someone who had been having the same internal argument for weeks and had arrived, again, at the same unresolved position. He needed BC. He needed it badly — sixteen BP out of three hundred and seventy was a resource so constrained it was barely a resource at all, and every time he tried to use the Blood Soldier ability he crashed into the same wall. The ability was the most powerful thing he had and he couldn’t use it properly and the reason he couldn’t use it properly was sitting there in the panel with a value of one.

He closed the panel.

‘After AGI one hundred’, he’d told himself. Well. AGI was one hundred.

He sat with the BC stat in the back of his mind and breathed carefully around the ribwork and listened to the forest, and thought about the army he couldn’t build yet, and the Hashira he’d just barely escaped, and the thirty-seven empty soldier slots waiting to be filled with something better than prisoners, and —

The command arrived like a hand reaching into his head.

Not painful. Not violent. It didn’t announce itself as external in the way he’d braced for, expecting something that felt like invasion — the memory of the Muzan control signal, the one the system had removed, had left him calibrated for an obvious intrusion. This wasn’t that. It arrived with the texture of a thought, wearing the clothes of a thought, but sitting in the wrong part of his mind, occupying space that wasn’t his.

‘Go to Mount Natagumo. Help the Spider Demon defend the mountain.’

He went still.

The ribs, which had been making their opinions known continuously for the last hour, went quiet — not because they’d resolved anything, but because everything else went quiet first.

He sat with the command and examined it carefully, the way you examined something you’d found in your house that you hadn’t put there. It had arrived through the blood connection — the modified one, the one the system had stripped of its ability to access his memories or override his will, but which still existed as a channel because the channel was biological and biology persisted. Someone had sent a command through it. Someone with the authority and the access to use that channel.

Not Muzan. He was almost certain of that, and his certainty had a shape he could describe: Muzan gave commands from a position of absolute ownership. He had stood in a field of blood and said ‘you are now a demon’ the way you stated weather, the way you stated ‘the ground is down’. A command from Muzan would feel like gravity. This felt like someone else using Muzan’s telephone.

Upper Moon. One of the twelve, using the hierarchy’s communication structure to reach down through the chain of command. Which meant there was a chain above him — a chain he’d avoided thinking about in detail, the way you avoided detailed examination of the specific mechanisms of things you were afraid of. He existed in the hierarchy whether he engaged with it or not, and apparently the hierarchy had noticed him and had a task.

Mount Natagumo.

He knew that name.

He knew it the way he knew many things in this world — from the outside first, from the perspective of the story rather than the experience, the knowledge carrying the particular quality of a spoiler rather than a memory. Mount Natagumo was where the Spider Family operated. Where Rui held his territory. Where Tanjiro and his group would arrive to fight through the mountain and face Rui at the center, and where the Flame Hashira and the Insect Hashira would enter from the other side.

Where people died.

He sat in the dark forest with a command sitting in the wrong part of his mind and thought about what following it would mean, and what not following it would mean, and what either option looked like from the perspective of a level thirty-seven demon with AGI one hundred and BP sixteen.

Following it meant going to a place where Hashira were coming. Not one Hashira — multiple. It meant going to a place where the story was already in motion, where outcomes were already determined by a shape he’d read the end of, where being present was being present in the middle of someone else’s catastrophe.

Not following it meant — what? Ignoring a command from an Upper Moon. In a hierarchy that resolved disagreements with methods considerably less conversational than the system. He was not controllable, the system had made sure of that, but he was also not invisible, as Jiro had recently demonstrated. And an Upper Moon looking for a demon who had received a command and failed to comply with it was a different category of problem from a Lower Moon being annoyed about territorial violation.

He pressed the back of his head against the tree bark and stared up through the canopy at the strip of sky visible between the branches.

‘Mount Natagumo’, he thought. ‘Of course. Why not.’

He wasn’t ready. He was aware he wasn’t ready — BP sixteen, zero soldiers, VIT six, ribs still arguing. He was acutely, specifically, anatomically aware that he was not ready for Mount Natagumo.

He also knew the shape of Mount Natagumo. He knew the terrain, knew the players, knew the approximate sequence of what was coming and who would survive it and what the mountain looked like from the story’s side of the glass. In every bad situation he’d navigated since waking up in blood, the one consistent advantage he’d had was the knowledge of a reader — the map of a world he’d been outside of long enough to see its shape.

He had that map here.

He could work with a map.

He let out a slow breath. Waited for his ribs to finish their complaint. Then he stood, straightened — carefully, the VIT six protest registering and being noted and not being acted upon — and oriented himself.

South. Mount Natagumo was south.

He had no soldiers. He had sixteen BP and a body mid-repair and a stat build that was extremely fast and had no staying power whatsoever, and he was walking toward a mountain full of spider demons and incoming Hashira and a boy with a checkered haori who had, in another version of this story, been the beginning of the end of everything that Muzan had built.

He started walking.

The forest moved around him quietly — branches, leaf litter, the small sounds of nocturnal things going about their uncomplicated lives. His SEN tracked it all with the idle thoroughness of a system that didn’t know how to do less than full capacity, cataloguing the ordinary details of a world that was dark and alive and completely indifferent to his problems.

He thought about BP.

Sixteen. That was the ceiling of what he could maintain. And every Blood Soldier cost ten BP to summon and maintained a drain he felt as a faint, constant pull. With sixteen, he could summon one and have six left over for emergencies. With six left over, the emergencies had to be very small.

He needed to feed before he reached the mountain.

Not for pleasure — he’d stopped framing it that way after the prison, stopped making the experience carry more narrative weight than it needed to. He needed it the way a machine needed fuel. Practically. On a timeline. He was walking toward a situation that would require him to be functional, and functional had prerequisites.

He adjusted his route slightly, toward where the SEN was catching the distant warm signatures of a settlement — not large, not the kind of thing that would attract Demon Slayer attention before morning, just a small gathering of people in the dark that his body had already begun to register as relevant.

He thought about the command while he walked. The texture of it, the part that had felt external, the specific register of an Upper Moon using the blood-line hierarchy to reach down and move a piece.

He wasn’t a piece.

He was going to Mount Natagumo. He had reasons of his own that were at least as compelling as the command — information, positioning, the chance to understand the mountain before the story fully arrived on it. He would be there. He would use what he knew. And whatever the Upper Moon who had sent that command thought it had dispatched to that mountain, what would actually arrive would be something that made its own decisions about what to do when it got there.

The settlement’s lights resolved through the trees ahead.

He walked toward them with the particular quiet of something that had learned to move without being heard, and behind him, south, the silhouette of a mountain waited in the dark.
