Steve Rogers arrived first.
He came through the tower's east entrance at seven forty-three in the morning with a bag over one shoulder and the unhurried quality of someone who had been ready before the call came and had simply been waiting for direction. Tony met him in the lobby, and Naruto watched from the mezzanine level above — not hiding, just positioned where he could observe the greeting before participating in it.
Steve was taller than the photographs suggested. Not dramatically — the photographs were accurate in scale — but there was a quality to his presence that photographs didn't capture, the specific gravity of someone who had been carrying significant weight for a long time and had learned to carry it as part of his natural posture rather than as an additional burden. He moved through the lobby the way someone moved through a space they were familiar with but did not take for granted.
Tony said something to him. Steve looked up toward the mezzanine.
His eyes found Naruto immediately — not scanning, not searching, finding. The perceptual directness of someone whose situational awareness operated continuously.
He nodded.
Naruto nodded back.
That was their introduction.
Wanda Maximoff arrived twenty minutes later.
She came in alone, no bag, the way someone came when they expected to leave quickly or expected not to leave at all. She was smaller than Naruto had pictured from the library articles — not small, but the photographs had suggested something more imposing, and the person who came through the door was a young woman in a dark jacket who walked with the careful self-containment of someone who had learned that their presence affected the space around them and was constantly managing that effect.
She stopped when she saw Naruto.
Not stopped walking — stopped internally. A stillness that was different from the ambient stillness of someone at rest.
Naruto felt it.
He felt her.
Not the way he felt chakra users — that was a different sense, a different register. This was more like the feeling of standing near a very large and very quiet body of water. Something deep and contained and moving underneath the surface in ways that the surface didn't fully communicate.
She was looking at him with an expression that was not what he expected.
Not assessment. Not the professional evaluation that Natasha used or the analytical attention that Tony used. Something more personal than that. More — interior.
"You feel like something I dreamed about," she said.
It was said quietly, not as a statement for the room, almost to herself.
"I've been told that before," Naruto said. "Usually by people who later try to kill me."
Something shifted in her expression. Not quite a smile — the preliminary movement that preceded one.
"I'm not going to try to kill you," she said.
"I know," Naruto said. "I would have felt it if you were."
She looked at him for a moment longer. "The chakra. It's—" She paused, choosing words. "When I use my abilities, I perceive energy. In most people it's simple. Structured. Like a single instrument." She paused again. "Yours is like an orchestra that's been playing for fifty years. Every section has its own history."
"That's the most accurate description I've ever heard," Naruto said honestly.
Kurama made a sound in his mind that was not quite a laugh.
She's perceptive, the fox said. Be careful with her.
Why careful.
Because perceptive people see things you're not ready to show yet. And you have things you're not ready to show yet.
Naruto filed this without responding and turned back to Wanda, who had moved to stand beside him with the natural ease of someone who had decided, in the space of thirty seconds, that proximity was acceptable.
"Tony briefed you on the situation," he said.
"The summary version," she said. "Ancient seal in your bloodline. Entity from outside the galaxy. Seventy-two-hour activation window for a beacon, now extended because you secured the catalyst." She paused. "He didn't explain what I'm doing here."
"You can perceive the energy landscape in a combat environment," Naruto said. "When HYDRA comes for the crystals — and they will — I need someone who can tell me where the Infinity-active components are in real time. Your perception and my Sage awareness overlap in ways that should be complementary."
She looked at him. "You planned the team composition yourself."
"Tony and I did," Naruto said. "He knows your capabilities better than I do. I knew what I needed."
"What did you need."
"Someone who could see what I can't when I'm inside the modification procedure," Naruto said. "During the procedure I'll be working at the cellular level. My external awareness will be limited. I need eyes that work differently from normal human senses."
Wanda was quiet for a moment. "You trust me with that."
"I trust your capability," Naruto said. "Trust comes from demonstrated reliability over time. I haven't had the time. But capability is assessable from observation, and yours is what I need for this specific role."
She considered this for a moment. "That's a very honest answer."
"I don't have the energy to maintain dishonest ones."
This time the shift in her expression went all the way to an actual smile — brief, small, but genuine.
She moved toward the main workspace.
Naruto watched her go and thought about what Kurama had said about things he wasn't ready to show yet.
He knew what they were. He was carrying them the way he always carried the things too large for the surface. They would stay there until there was time to take them out properly. Not now. Now was for the work.
Thor arrived through the window.
Not the door. The window.
The window that was on the forty-third floor and had not been open.
There was a specific sound — a deep resonant crack, not quite thunder, the compressed version that Mjolnir created when Thor adjusted velocity at close range — and then the window that had definitely been closed was open and Thor was standing in the workspace in full armor with his cape settling around him and the particular energy of someone to whom the normal approach had never been the most interesting option.
He looked around the room.
His eyes landed on Naruto.
He crossed the workspace in five strides and stopped directly in front of him and looked at him with the specific attention of someone who had encountered significant power across multiple realms and was assessing what category this particular example belonged to.
Naruto looked back.
Thor extended his hand.
"Thor Odinson," he said. "Son of Odin. God of Thunder. And you are the one Tony called about."
"Naruto Uzumaki," Naruto said, shaking the hand. Thor's grip had the quality of someone who had spent a very long time learning to modulate force because the unmodulated version broke things. "Son of Minato Namikaze and Kushina Uzumaki. Former Seventh Hokage of the Hidden Leaf Village. Currently occupying a borrowed body in a dimension I've never been to before."
Thor's expression moved through several things rapidly. "Former Hokage. A title of leadership."
"Highest leadership position in my village," Naruto said. "Roughly equivalent to king, though the selection process was different."
"And you carry great power within you," Thor said. He wasn't asking — he was confirming something he had already perceived, the specific sensory capacity of someone attuned to energy across realms. "I feel it. Old. Very old. Older than you."
"The Nine-Tails Fox," Naruto said. "And a sealed body of knowledge from my ancestor Uzumaki Mito. Yes."
Thor looked at the ceiling thoughtfully. "Uzumaki. I know that name."
Tony looked up from his workbench. "You know the name?"
"Distantly," Thor said, still with the ceiling-looking expression of someone sorting through a large and ancient memory. "There were stories in Asgard. Old stories, from the time before my grandfather's grandfather. About a world of warriors who sealed their power into living vessels. The Allfather's archives have references to — a rift, I think. Between the Nine Realms and a world that existed in parallel but separate. The world of chakra."
The workspace was quiet.
"The shinobi world is documented in Asgardian archives," Tony said flatly.
"Documented is a strong word," Thor said. "Referenced. In the way that ancient things are referenced — incompletely, with more mythology than fact." He looked at Naruto. "But the Uzumaki name is there. Associated with a sealing lineage of extraordinary power." He paused. "And associated with a warning. Something the Allfather took seriously enough to include in the primary archives."
"The Consuming Attention," Naruto said.
Thor turned from the ceiling and looked at him with full attention.
"You know it," Thor said.
"I read about it this morning. In my ancestor's message."
"The Allfather called it by a different name in the Asgardian records," Thor said. "The translation from the old language is imprecise. But the meaning was approximately — the Hunger Between Stars." He paused. "It was considered a legend. A story used to explain why certain things in the universe seemed to simply — disappear. Civilizations. Stars. Things that should have persisted but didn't." Another pause. "We thought it a story."
"It's not a story," Naruto said.
"No," Thor said. "I see that now." He looked around the room at everyone present — Tony, Steve who had come in from the side, Peter, Wanda, Natasha in her corner. "And you intend to stop it."
"Eventually," Naruto said. "The immediate problem is the beacon. After that — yes. Mito left the techniques in the seal. I need time to access them fully and develop the capacity to use them."
"Time," Thor said. "And assistance."
"Potentially," Naruto said. "I don't know yet what the techniques require in terms of configuration. I'll know more after I read them."
Thor nodded. Slowly, with the weight of someone making a decision.
"The Allfather's archives may have more," he said. "If the Uzumaki seal was referenced in the primary records, there may be additional context. Information about the Hunger Between Stars that your ancestor didn't have when she built the seal." He paused. "I will return to Asgard after this operation and search the archives personally."
"That would be useful," Naruto said.
"It would also give me a reason to avoid the reconstruction committee meeting Sif has been organizing for three months," Thor said, with the expression of a man who had just identified an additional benefit. "So the arrangement serves multiple purposes."
Tony made a sound that might have been a suppressed laugh.
Bruce Banner arrived via video call — physically he was in Geneva, where his research on the Infinity Residue had been based for the past year, and the transit time made physical presence impractical given the timeline. He was on the main screen, his connection stable, and he had clearly been awake and working since the facility operation because the stack of papers beside him had grown significantly and he had the particular focused energy of a scientist who had found a problem that had his complete attention.
"The modified rekeying parameters," Bruce said, without preamble, when Tony brought him into the briefing. "I've been running independent models. FRIDAY's estimates are conservative — I think the actual chakra expenditure for keying the seal to your specific signature might be higher than projected."
"Higher than thirty-five percent," Naruto said.
"Possibly," Bruce said. "The challenge is that we're essentially asking the seal to recognize a chakra signature it's never encountered. Mito built the seal before you existed. The counter-configuration has to be written in a language the seal understands, which means translating your specific chakra signature into the sealing grammar she used." He paused. "I've been working on the translation framework. It's not straightforward."
"Can it be done," Naruto said.
"Yes," Bruce said. "But it will require active input from you during the translation process. Not just chakra output — specific. I need your chakra signature characterized at a level of detail that lets us build the lock correctly."
"How do you characterize it," Naruto said.
"Meditation output while I monitor," Bruce said. "You generate a controlled chakra expression and FRIDAY records the specific pattern. We build the translation from the recorded pattern." He paused. "It would take about an hour. We should do it before you go into the modification procedure."
"When do you need me ready," Naruto said.
"The sooner the better," Bruce said. "But your recovery takes priority. The procedure requires what it requires."
"Seventeen hours," Naruto said. "I need seventeen more hours of recovery. We run the signature characterization at hour fifteen, which gives the translation framework two hours of build time before the procedure."
"That works," Bruce said.
Tony looked at the clock. "That puts the procedure at approximately midnight tonight." He looked around the room. "HYDRA has seventeen hours to attempt a recovery of the crystals."
"They'll attempt it before then," Natasha said. She had moved from her corner during Thor's arrival and was now at the edge of the main workspace, arms crossed, in the configuration of someone who had shifted from assessment to operational mode. "They lost the crystals eight hours ago. They know where they are. They're planning right now."
"How long to plan an assault on Stark Tower," Steve said. He had been quiet through most of the assembly — listening, filing, the way Steve apparently processed situations before he was ready to contribute to them.
"Depends on resources available," Natasha said. "HYDRA's New York cell had the facility team and the rooftop team we've already encountered. Calling in additional resources takes time. But they have other cells they can reach." She paused. "My estimate: they move within six to eight hours."
"Six to eight hours," Tony said. "Which is before Naruto's recovery window closes."
"Yes," Natasha said.
The room absorbed this.
"Then we prepare for two concurrent operations," Steve said. He said it cleanly, with the authority of someone who had spent his life managing exactly this kind of dual-requirement situation. "Defense of this facility and the crystals for as long as necessary, transitioning to protection of Naruto during the modification procedure."
"I can't do the procedure if there's active combat in the building," Naruto said. "The procedure requires the depth of meditation I was describing. External disruption at that depth—"
"Would interrupt it," Tony said.
"Would abort it," Naruto said. "I'd have to surface immediately. Any modification partially executed at the cellular level when aborted would need to be assessed before restarting. That takes time we might not have."
"So the facility needs to be secured before you go into the procedure," Steve said.
"Yes."
Steve looked at the assembled room. "Then that's the first objective. We hold the facility, we clear any HYDRA assault, and when the building is secure Naruto goes into the procedure." He looked at Naruto. "How long does the procedure take once you start."
"Unknown," Naruto said. "Estimated twenty to forty minutes based on Tony and Bruce's modeling. But that's a first estimate for a procedure type that's never been done before."
"We hold until it's done," Steve said. It was not a question or a negotiation. It was the statement of a man who had held positions under worse conditions and expected to do so again.
Thor raised Mjolnir slightly. "I have held positions before."
"We know," Tony said.
"I simply wanted to establish that I was prepared to do so again," Thor said. "In case there was any uncertainty."
"There wasn't," Tony said.
"Good." Thor lowered Mjolnir. "Then I will also require coffee. The journey through the Bifrost at short notice always leaves me wanting coffee and I notice you have a very large machine in the corner."
Peter got up and went to the coffee machine with the expression of someone who was genuinely happy to have a concrete task.
Naruto looked at the assembled room.
Thor examining the coffee machine with the focused interest of someone encountering a technology they had interacted with before but never studied. Steve beside Tony at the main display, the two of them falling into the natural working shorthand of people who had operated together across years. Wanda near the windows, looking out at the city with the particular stillness that was her version of active processing. Natasha at the edge of the workspace, already reading the tactical geometry of the floor they were standing on. Bruce's face on the screen, surrounded by papers, running models.
Peter handing Thor a cup of coffee. Thor taking it with genuine gratitude.
Naruto stood in the middle of all of it.
He had assembled war councils before — in the Fourth Great Ninja War, in the smaller conflicts that came after, in every large operation that required more than one person's capabilities. He knew what a good council felt like and he knew what a bad one felt like and he knew the difference was never about individual power or competence. It was about whether the people in the room were there for the same thing.
These people were there for the same thing.
He didn't know them yet. He had known them for less than two days. But they were there for the same thing and that was the foundation that everything else could be built on.
"Thank you," he said. Not to any one of them. To the room.
Steve looked at him. "Don't thank us yet," he said. "We haven't done anything."
"You came," Naruto said. "That's something."
Steve was quiet for a moment. Then something shifted in his expression — the thing that was underneath the Captain America expression, the thing that was just Steve Rogers, which was apparently a person who understood what it meant to feel alone in a world you hadn't been born into.
"Yeah," Steve said. "Okay. That's something."
Naruto turned back to the window and looked at the city.
Seventeen hours.
He breathed in.
The work continued.
