The Kerenth Operations Center was busier than Adam had ever seen it at 0600.
He walked out of Bay 3 and into a corridor full of people. Analysts in civilian dress moved between briefing rooms with tablets pressed to their chests. Two response teams he didn't recognize were gearing up in the staging area across the hall, checking equipment and testing comm channels in low, clipped voices. A duty officer passed him without a glance, talking fast into her headset about a "secondary breach confirmation in the Velden corridor."
He'd been gone just under three days, Earth Prime time. L3 ran at a 4:1 dilation ratio, which meant the nearly two weeks he'd spent in the Hunter Exam had compressed into a bit under three days back home. Three days, and the Operations Center had turned into a command post.
He found Hana in the Sigma-4 briefing room. She was alone, sitting at the long table with a thermos of coffee and her tablet propped against it, scrolling through what looked like an incident feed. The thermos was nearly empty and she looked like she hadn't slept.
"Welcome back," she said without looking up.
"What happened?"
"Three incursions in the last six days. Two Vethrak swarms, one Korrath pair." She turned the tablet toward him. The incident feed showed a cascade of timestamped entries, each one tagged with severity, location, and responding team. "Sigma-2 handled the first swarm in the port district. Twelve hostiles, clean. Sigma-6 caught the Korrath pair two days later near the Nordvik industrial sector. Both L3, thermal class. One officer took second-degree burns across his torso before they brought them down."
"And the third?"
"Yesterday. Another swarm, nineteen this time, eastern residential district. Sigma-4 deployed without you." She paused. "Tomás took point. I ran flanking suppression. Ren handled the strays."
Adam noticed the half-empty thermos and the way she had not blinked since he came in. The room itself seemed to have stopped resting. Something in the corridor had changed in the three days he had been gone, and his body was the last thing to catch up.
"Sera?"
"Sera commanded from the operations room. She pulled herself from the field after the second incursion. Said her deployment rotation was too close and she needed to conserve strength." Hana's eyes shifted to him for the first time. "Nineteen hostiles in a residential zone at 0300. We cleared it in twenty-three minutes. No civilian casualties."
Nineteen hostiles was the largest single breach he'd heard of in Kerenth's operational zone. The biggest before this had been fifteen, eight months ago.
"Is this normal?"
Hana looked at him. "No."
He debriefed with the duty officer in room six. Standard procedure. World description, threat assessment, actions taken, injuries sustained. Adam kept it factual and generic, the same way he always did. He described the exam structure, the Nen-heavy environment, the designated targets, and the combat engagement without identifying anyone by name or referencing anything that would place the world in a specific fictional context.
The duty officer, a man named Algren who'd been doing these debriefs for eleven years, took notes without interrupting. At the end he asked the same question he always asked: "Anything you want to flag for strategic analysis?"
"The world has an unusually high concentration of advanced Nen users. Several individuals with capabilities that would qualify as L4 or higher if they were Explorers. It's a training-rich environment for anyone running a Nen build."
Algren noted it. "Rating?"
"Successful."
Algren waited a beat, pen still. Adam didn't elaborate. The duty officer nodded, wrote something down, and closed the file.
The Hunter License sat in his interior pocket the whole debrief. He did not take it out. He did not mention it. The card had been earned in a world he would not voice in this room, and the people in this building had names of their own dead to think about.
Adam checked his balance in the corridor afterward. 11,270 NP. The Efficiency Index sat at 90.1, up from 88.4 after the Attack on Titan expedition. The System Insight notation was still there, the same cryptic line it had shown since he'd first unlocked the metric: Efficiency thresholds may unlock opportunities not available through standard Bazaar listings.
90.1. Keep climbing.
The next nine days passed in training and tension.
The HEC approved Adam's request for higher-tier sparring partners. They assigned Kira Strand, an L4 Explorer with Enhancement-dominant Nen and a hardening technique that turned her forearms into something denser than steel. Their sessions had shifted quickly from measured exchanges to something closer to real combat. Kira was not as versatile as Adam. She didn't need to be. Her build was focused and deep where his was broad, and the depth gave her striking power that made his ribs ache through Ken.
Sera called a team meeting the second night after Adam's return. The incursion data was worse than the corridor buzz suggested. Global frequency had been climbing for two years, and the curve wasn't linear. It was accelerating. Kerenth alone had gone from six incursions in the twelve months before Adam joined Sigma-4 to fourteen in the twelve months after. And the hostiles were getting stronger. L4-class entities were appearing in nearly one out of every five breaches, up from eight percent eighteen months ago.
Sera was blunt: "Sigma-4 is an L3 team. Adam is currently performing above L3 metrics. When the next high-grade incursion hits our zone, he's going to be carrying the engagement."
Nobody argued.
The old Explorer families were mobilizing. The Kessler Foundation had deployed three reserve members. The Valdros military houses were pulling people out of retirement. These were families who'd built generational knowledge bases and structured progression paths over decades. When they started fighting again, it meant the daily grind had become existential.
The incursion hit on the ninth day.
Adam was in the HEC gymnasium, mid-session with Kira, when both their comm-links chirped simultaneously.
"All response teams. Breach confirmed. Sector 7-North, Aldermere residential district. Multiple hostiles. Strength estimate pending. All teams deploy."
Kira stepped back. "Go."
Adam was already moving.
Sigma-4 assembled in the staging area in under four minutes. Sera was there first, her Mana barrier equipment already charged. Tomás arrived twelve seconds later, still pulling his boots on. Hana came through the east corridor with her tablet, eyes on the live feed.
"Seven hostiles confirmed," Hana said. "Four Korrath, two Thassari, one unclassified. The unclassified is large. Sensor readings are putting its thermal output above anything we've catalogued in our operational zone."
"L4?" Sera asked.
"Borderline L5."
The room went quiet for half a second.
Ren appeared in the doorway. She'd been in the apartment when the call came and she'd covered the three kilometers to the Operations Center in under two minutes.
"Formation," Sera said. "Standard incursion protocol. I hold the perimeter and project barriers for civilian cover. Adam, you're on the unclassified. You're the only one on this team with the output to engage something at that level. Tomás, Hana, Ren, you handle the six catalogued hostiles. Pairs. Tomás and Ren on the Korrath, Hana on the Thassari."
"Solo on two Thassari?" Hana asked. Not objecting. Confirming.
"Your Domain Echo will track them better than a partner would. Disable, don't engage in prolonged combat. We clear the area and protect the evacuation corridor."
They moved.
The transport dropped them at the edge of the breach zone six minutes after the initial alert. Aldermere was a residential district in Kerenth's northeast quadrant. Mid-density housing, a school, two parks, and a commercial strip. Population within the immediate breach radius: approximately twelve thousand people.
Adam's Observation Haki expanded the moment he stepped off the transport.
The civilians were already moving. Emergency sirens had activated within ninety seconds of the breach, and the Kerenth civil defense protocols were functioning as designed.
Beyond the evacuation flow, the hostiles.
The four Korrath were spread across a two-block area, their mineral-based bodies radiating thermal energy that Adam's Haki registered as a dense, angry heat. Two were L3 baseline. The other two were larger, their thermal signatures running hotter. L4 class. One was already engaged with a police barrier unit that was doing nothing to slow it down.
The two Thassari moved as a pair through the commercial strip, their crystalline armor refracting the emergency lights into scattered patterns.
And the unclassified.
It stood in the center of the breach zone, in a park that had been a playground twenty minutes ago. It was Korrath-adjacent in form, roughly three meters tall, but its thermal output was in a different category. The air around it rippled with heat distortion, and the ground beneath its feet had blackened and cracked in a circle that extended four meters in every direction. The playground equipment was melting. Swing chains sagged like warm taffy. The rubber surface had liquefied into a dark, smoking slick.
Borderline L5. In a residential district. In my city.
"I have eyes on the primary," Adam said into the comm. "Confirming borderline L5. It's stationary in the park. The thermal output is extreme."
"Copy," Sera said. "I'm establishing the barrier line along Aldermere South. Adam, keep it in the park. Don't let it reach the residential blocks."
"Understood."
Adam activated the Nanosuit's Armor Mode and moved.
The fight with the borderline L5 was the hardest thing Adam had done since Hisoka.
The entity didn't move fast. It didn't need to. Its thermal aura was a weapon in itself, a field of radiant heat that intensified as Adam closed the distance. At twenty meters, the air was uncomfortably warm. At ten, his Nanosuit's temperature readings climbed past the point where unprotected skin would blister. At five, the Nanosuit's outer layer was actively absorbing thermal energy and rerouting it, the suit's integrity display dropping by fractions of a percent with each second of exposure.
He hit it with a Dodon Beam. The piercing beam struck the entity's left shoulder and punched a hole through the outer mineral layer, releasing a jet of superheated gas. The entity turned toward him. Its thermal output spiked.
The ground beneath Adam's feet cracked and blackened. He jumped back, using TK to boost his movement, and fired two more Dodon Beams from different angles. Both hit. Both penetrated. Neither slowed it down.
The entity raised one arm and discharged a concentrated thermal pulse. Not a fireball. A wave of pure radiant heat that expanded outward in a half-dome, scorching everything in a forty-meter radius. Adam threw himself sideways, Ken flaring to maximum, Ryu redistributing his aura to the side facing the blast. The heat wave hit him like opening an oven door the size of a building. His Nanosuit's integrity dropped from 94% to 81% in the span of two seconds.
He landed, rolled, and came up running. The entity was following him now, each step leaving a molten footprint in the earth. Slow, but relentless. The heat radiating off it was so dense his Hamon rhythm had to work twice as hard to keep his breathing useful, and his Nen output was bleeding off into the air around him before it could reach the target.
I can hurt it. I can't stop it. Not from range.
He needed to get close. Ko range. One concentrated strike to the structural core that his Haki could sense buried in the center of the mineral body, a dense node of energy that functioned as the entity's heart. Break that, and the thermal output would collapse.
He used In to conceal a ring of Nen Mines around the entity's projected path, then circled wide, firing Guided Volleys to pull its attention east, away from the residential blocks. The entity turned to track the incoming projectiles and walked directly over the mines.
The detonation was significant. Six concealed charges went off simultaneously beneath the entity's feet. The explosion cracked its lower body and sent fragments of mineral plating scattering across the park. The entity staggered.
Adam closed the distance in three seconds. Nanosuit in Power Mode. Ko loaded into his right fist, every unit of aura concentrated into the strike. His Haki locked onto the core.
He hit it.
The impact was like punching a furnace. The Ko strike broke through the cracked mineral plating and reached the energy core, and for one second, Adam felt the concentrated heat of the thing's interior through his fist, through the Nanosuit, through his Ken. His hand burned. His forearm burned. The Nanosuit's integrity on his right arm dropped to 12%.
The core shattered.
The entity's thermal output collapsed instantly. The radiant heat field winked out. The three-meter body went dark and began to crack along fault lines as the energy that held it together dissipated. It fell in sections, like a statue coming apart, and the pieces hit the ground with dull, heavy thuds that kicked up ash from the scorched earth.
Adam stepped back. His right hand was burned through the Nanosuit, the skin red and blistering from the wrist to the knuckles. He activated Hamon. The breathing rhythm pushed healing energy into the damaged tissue and the pain dropped from sharp to manageable.
"Primary down," he said into the comm.
"Copy," Sera said. "Korrath status?"
"Two down," Tomás reported. He was breathing hard. "Ren's finishing the third. The fourth is moving south toward the evacuation route."
"South?" Sera's voice changed. "How far south?"
"Three blocks. It's fast. Faster than the others."
Adam's Haki swept south. He found the L4 Korrath immediately. It had broken past Tomás and Ren's containment and was moving toward the evacuation corridor at a speed that didn't match its mineral body. Thermal propulsion, maybe, using its own heat output as thrust. It was covering ground at a rate that would put it in the middle of the civilian evacuation route in under a minute.
"Sera, it's heading for the evacuation corridor," Adam said.
"I see it. I'm repositioning."
Through Haki, Adam watched Sera move. She'd been holding the barrier line along the southern edge of the breach zone, a wall of shaped Mana force that channeled civilians away from the combat area. She dropped the main barrier and sprinted north to intercept the L4 Korrath.
Adam was already running, but he was six blocks away. Tomás was four blocks east. Ren was with him. Hana was two blocks north, locked in close engagement with the Thassari pair.
Sera reached the intersection of Aldermere South and Brinkley Street before the Korrath did. The evacuation corridor ran along Brinkley, a wide boulevard lined with residential buildings. Civilians filled the street, moving south in a steady stream that had thinned but not stopped. There were still people on the road. Families. An elderly man with a cane being helped by a teenager.
The L4 Korrath came around the corner at speed. Its thermal field was running hot, the air around it distorting with waves of heat that cracked the windows of the buildings it passed.
Sera planted herself in the intersection.
She raised both hands and projected the largest barrier Adam had ever seen her create. A wall of concentrated Mana force that stretched across the full width of Brinkley Street, floor to roofline, translucent and shimmering with the blue-white light of her energy at maximum output. The barrier sealed the intersection.
The Korrath hit the barrier at full speed.
The impact was enormous. The barrier held. Sera's feet slid back half a meter on the asphalt, her Mana output spiking to compensate. The Korrath rebounded, staggered, and hit the barrier again. And again. Each impact sent cracks spiderwebbing through the Mana structure, and Sera repaired them in real time, pouring energy into the weak points faster than the entity could break them.
But the Korrath wasn't just hitting her. It was burning.
Its thermal field pressed against the barrier surface and the temperature climbed. Mana barriers weren't designed for sustained thermal assault. They absorbed kinetic energy and dispersed it, but heat was different. Heat was constant, pervasive, and it degraded the Mana structure from the inside out.
Adam saw it through Haki. Sera's energy output was climbing to compensate, and the rate was unsustainable.
"Sera, disengage. I'm ninety seconds out."
"Negative. Corridor's still active. There are people behind me."
"You can't hold that for ninety seconds against thermal assault."
"Then run faster."
Adam ran faster. Power Mode. Every boost the Nanosuit had. His burned hand screamed and he ignored it. Sixty seconds.
Through Haki, the picture deteriorated. The barrier was thinning. Sera's Mana reserves were dropping. The Korrath was pressing harder, its thermal output climbing as if it sensed the weakness.
Fifty seconds.
The Korrath reared back and discharged a concentrated thermal pulse into the barrier's center. A lance of pure heat that hit the barrier at its weakest point and burned through it like a blowtorch through paper.
The barrier broke.
Sera didn't step back. She reformed the barrier behind the breach point, creating a second wall between the Korrath and the civilians. Smaller. Thinner. Her reserves were almost gone and Adam could feel it through Haki, the way her energy signature was flickering at the edges.
The Korrath stepped through the gap in the first barrier and hit the second one.
Sera held.
Thirty seconds.
The Korrath discharged again. The thermal pulse ate through the second barrier in under four seconds. Sera staggered. Blood ran from her nose and the corners of her eyes, the physical signs of Mana overexertion that Adam had read about in training manuals but never seen in person.
She created a third barrier. It was barely there. A shimmer in the air, thin as glass, holding together through nothing but will.
The Korrath stepped through.
Sera didn't create a fourth barrier. She had nothing left. Instead, she stepped forward and put her body between the Korrath and the street full of people behind her.
She put both hands on the entity's chest.
The last of her Mana discharged on contact. A shaped pulse, not a barrier but a directed force blast, the kind of technique that burned whatever reserves the caster had left. The blast hit the Korrath at point-blank range and drove it backward ten meters, cracking its chest plating.
The thermal backlash hit Sera at the same moment. The entity's heat field was still active, still running at L4 combat intensity, and Sera had no barrier left, no Mana reserves, no protection.
Adam was fifteen seconds away when her comm went silent.
He came around the corner on Brinkley Street at a dead sprint and saw the Korrath pulling itself upright from the rubble of the first barrier. Its chest was cracked. Behind it, the intersection was scorched black.
Sera was on the ground. She wasn't moving.
Adam hit the Korrath with everything he had left. Ko strike to the cracked chest plate. The weakened plating shattered on impact and his fist found the energy core. It burst. The entity collapsed.
He turned to Sera.
She was on her back in the intersection, her field jacket charred, her hands burned to the forearms, her face slack. Adam's Haki read no energy signature. No Mana. No vitals.
He knelt beside her. He reached for the Healing Charge in his Spatial Pocket, knowing it was already too late, and pressed it against her chest anyway.
The device activated. The indicator light cycled from green to yellow to red.
Red meant no viable tissue response. Red meant the damage was beyond what stabilization could address.
Adam knelt in the scorched intersection of Aldermere South and Brinkley Street, holding a depleted Healing Charge against the chest of a woman who had taught him what it meant to hold a line, and the charge's red light blinked in the silence because there was nothing left to stabilize.
The rest of the engagement lasted eleven minutes.
Tomás and Ren finished the remaining Korrath. Hana neutralized both Thassari. A backup team from Sigma-2 arrived and secured the perimeter.
Civilian casualties: zero.
Explorer casualties: one.
They brought Sera back to the Operations Center in a body bag. Adam carried one end. Tomás carried the other. Hana walked ahead, clearing the corridor, and Ren walked behind, saying nothing. The bag was lighter than Adam expected. Sera had always been compact in person, and what was inside the bag was less than that, the body's weight stripped down by what fire had taken before the rest of her could be carried out.
The HEC issued a formal notification the following morning.
SIGMA-4 OPERATIONAL STATUS UPDATE
Team Captain Sera Lund: KILLED IN ACTION
Cause: Mana reserve depletion during sustained barrier operation. Thermal exposure following reserve collapse.
Engagement: Aldermere Residential Incursion, Kerenth Sector 7-North
Civilian Casualties: 0 (evacuation corridor successfully maintained)
Team Status: Operational (reduced)
Interim Command: Hana Sato (effective immediately)
Permanent command assignment pending HEC review.
Hana accepted the interim command without comment. She sat in Sera's chair at the morning briefing and ran through the day's rotation schedule and the after-action review as if she'd been doing it for years instead of hours.
Adam watched her and thought about the way Sera had talked about losing the previous team member, eighteen months before Adam joined. "The position hasn't been filled because the HEC wanted a specific profile." She'd said it with the matter-of-fact directness that she applied to everything, and underneath it was the thing she never said aloud, which was that she'd spent eighteen months making sure the next people who filled those seats could survive what had killed the last person.
She'd been right about Adam and Ren. They could survive. They were strong enough, fast enough, adaptable enough.
She'd been wrong about one thing. She'd assumed she would be there to command them.
AN: If we get to 600 power stones this week I will release a bonus chapter.
