Attack on Titan fanfic Levi Ackerman (29) Aria Reyes (19) He’s Captain she’s a lieutenant This’ll take place during the events of attack on Titan

Chapter 5: Chapter 5

The dust in the Strategy Headquarters never settled anymore. It was a fine, granular grit that seeped into every ledger, every map seam, every cup of tea left unattended for five minutes. It was the dust of shattered walls, of broken cities, of a world violently expanded. Levi despised it.

He ran a cloth along the edge of the briefing table, his movements slower than they used to be. The stiffness in his right side was a permanent guest now, a souvenir from a thunder-spear and a forty-foot fall. He accommodated it, worked around it, but the pain was a constant, low-grade hum beneath everything, like the new, uneasy silence of a world without the Colossal Titan’s looming threat.

Bertholdt was dead. Reiner had escaped, a scarred and fleeing wreck. Eren was… changed. And Armin Arlert, small, brilliant Armin, now carried a sun in his stomach and the ghost of a boy in his head.

The door opened. Levi didn’t look up. The footfalls were too light for most soldiers, hesitant. He knew who it was.

“Captain.”

“Arlert.” Levi dipped the cloth in a small basin of clean water, wrung it out with a tight twist. “If you’re here for a debrief, the schedule’s on the wall. I’m busy.”

“It’s not about a debrief.” Armin’s voice had lost its youthful waver. It was quieter now, tempered by fire and unspeakable weight. “It’s… personal. A memory. But not mine.”

That made Levi stop. He placed the cloth neatly over the rim of the basin and turned. Armin stood just inside the doorway, his hands clasped in front of him. He looked older than his years, shadows permanent beneath his eyes, but his gaze was sharp, focused in a way that was entirely his own, yet somehow… not.

“The Founder’s power is supposed to connect all Subjects of Ymir,” Armin continued, his words careful, measured. “But the Colossal… it’s different. It’s like standing too close to a furnace. The previous holder’s memories don’t flow; they sear. They’re intense, fragmented. Mostly heat and fear and… regret. But sometimes, there are clear pictures.”

Levi leaned back against the table, crossing his arms. The movement pulled at his scarred ribs. He said nothing.

Armin took a breath, steeling himself. “I think Bertholdt knew Aria. Lieutenant Reyes.”

A cold, familiar stone dropped into Levi’s gut. He kept his face impassive. “She was his commanding officer for a time in the 104th training cadre. He would obviously know her, Arlert.”

“No.” Armin shook his head, his brows furrowed in concentration. “I mean like… recently. The memory is fuzzy, like looking through warped glass. But it’s there. She’s… smiling.”

The word landed in the dusty room like a physical object.

“Smiling,” Levi repeated, his voice flat.

“Laughing, actually. At something Reiner said.” Armin’s eyes were distant, looking at a scene playing out on the wall behind Levi. “She’s dressed differently. Not in uniform. She’s wearing a nice blouse. Embroidered, with little vines along the collar. White pants, slim-fit. And brown boots that lace up to her knees.”

He described the clothes with a tailor’s precision, the detail ripped from a stolen memory. The image formed, unbidden and agonizingly vivid, in Levi’s mind: Aria, alive, in civilian clothes, laughing in good light. A version of her that had never existed in Paradis. A version that had existed after.

“The setting is bright,” Armin murmured, almost to himself. “A courtyard, maybe. Potted plants. The sun is on her face. She looks… healthy. Rested. It’s a happy memory. For Bertholdt, I mean. It feels warm when I recall it.”

Levi pushed off the table and walked to the window. He looked out over the reconstruction efforts, the crews moving like ants over the rubble of Wall Maria. The dust was everywhere. He could taste it.

“When?” The single word was ground out.

“I don’t know. The memories aren’t timestamped.” Armin’s focus returned to the room, to Levi’s rigid back. “But it feels concurrent with other memories of Liberio. Of their home. It’s after.” He paused. “It’s after we believed she died.”

The logic was irrefutable. It was the kind of connective tissue Erwin would have seized upon, a data point that transformed a tragedy into a tactical puzzle. Bertholdt’s warm, happy memory of a smiling, well-dressed Aria, post-abduction.

Levi’s knuckles ached. He realized he was gripping the windowsill, his fingers pressing into the stone hard enough to bleach the skin.

“Why are you telling me this?” Levi asked, still not turning.

“Because you deserve to know she might be alive,” Armin said softly. “And because if she is, and she’s there, with them… she’s a variable we never accounted for. What if she wasn’t just a prisoner? What if she’s…”

He didn’t finish. He didn’t need to.

What if she’s one of them now?

The question hung in the dusty air, more toxic than any gas. Levi saw it all with a brutal, crystalline clarity. The performance in the forest. The precision stomp. Not an execution, but an extraction. A rescue, from their point of view. Reiner’s words in that sterile room, words he’d never heard but could now imagine with terrible ease: You don’t have to hide anymore.

He saw the girl from the report, the one who organized chaos, who thought too much, who had a sloppy paperwork trail for a dead Titan that no one could explain. A variable. An asset.

He turned from the window. His face was a mask of calm, but his eyes were like chips of flint. “You’ve told anyone else this?”

“No, sir.”

“Good. Keep it that way. This is a fragment, Arlert. A ghost in a dead boy’s head. It proves nothing. It changes nothing.”

But it changed everything. The carefully maintained tomb he’d built in his mind, the one he visited only to shore up his resolve, was now cracked. Light was getting in. A terrible, confusing, hopeful light.

Armin nodded, understanding the order. He turned to leave.

“Arlert.”

“Yes, Captain?”

Levi’s gaze was fixed on a point on the far wall, on a map that was now hopelessly out of date. “The next time you… sift through those memories. If you see her again. Notice the details. The background. Who else is there. What they’re saying.”

“You want me to spy on a memory.”

“I want you to gather intelligence,” Levi corrected, his voice lethally quiet. “From the only source we have behind their lines.”

Armin swallowed, the weight of the request settling on him. He wasn’t just a soldier with a Titan’s power anymore. He was a keyhole into a past that was still alive. “I’ll try.”

After he left, Levi stood perfectly still in the center of the room. The dust motes danced in a slant of afternoon sun. He looked at the clean table, the neatly arranged basin and cloth. The order was a lie.

A smiling girl. An embroidered blouse. Laughter.

The mess wasn’t in the dirt. It was in the not knowing. Erwin had been right about that, too. But now, he knew something. A fragment. A glimpse of a pair of brown, lace-up boots in a sunny courtyard.

It was enough. Enough to turn a closed book back into an open file. Enough to transform a quiet grief into a quiet, burning purpose.

He walked to the map. With a firm, deliberate stroke, he drew a line through the small, dark ‘X’ in the forest. That mystery was obsolete. His finger moved across the sea, to the estimated location of a continent called Marley, to a city named Liberio.

He didn’t mark it. He didn’t need to.

The dust would have to wait. There was a different kind of cleaning to do.

There was a different kind of cleaning to do. It involved grit of a different texture, not dust, but the coarse sand of the Liberio training grounds that stuck to sweat and steamed away from Titan skin. It was a cleansing by exhaustion, by repetitive, bone-jarring impact, until thought was pounded into a numb, useful silence.

The sun beat down on the cracked earth of the coastal reserve. From her vantage point within the Guardian Titan’s nape, Aria saw the world through a prism of light refracted through crystalline armor. Her Titan form was, as Porco had guessed, elegant. Lean and fifteen meters tall, it was sheathed in plates of smooth, opalescent white that gleamed like sea-washed bone. In its right hand, a long, sleek blade of hardened light extended from the fist, humming with a faint, resonant energy.

Across from her, the Armored Titan was a blocky fortress of dark, layered plating. It shifted its weight, causing the ground to tremble.

“YOU’RE HOLDING BACK WITH YOUR STRENGTH ARIA.” Reiner’s voice echoed, slightly muffled, from where he’d peeled back the nape armor to yell up at her. “I HAVE ARMOR. HIT ME.”

The Guardian Titan’s head, stylized and helmet-like with a narrow visor for her to see through, tilted. Inside the steaming chamber of its nape, Aria rolled her eyes. The Titan’s hand came up, its middle finger extending in a universally clear, rude gesture.

“I DON’T NEED THE ATTITUDE I NEED TO BE HIT.” Reiner said flatly, his patience clearly thinning. He vanished back into the protective shell.

A low, guttural rumble vibrated through the Guardian’s form, a sound Aria had learned to project—a grumbling ‘yeah yeah’ if a Titan could sigh. She settled into the stance they’d drilled, feeling the strange, fluid connection to the massive body. It was less like piloting a machine and more like wearing a second, tremendously powerful skin. The instinct was to deflect, to parry, to use the blade. To guard.

The Armored Titan charged. It was a terrifying sight, a locomotive of flesh and plating. The old soldier in her screamed to dodge. The new instinct was to stand firm.

She pivoted at the last second, not away, but into the charge. The white armor on her left shoulder braced. She let the momentum carry her, twisting at the core of the Titan, and drove her right fist in a tight, vicious arc.

It connected with a catastrophic CRACK that split the air. Not the ring of plate on plate, but the sound of something fracturing. A web of hairline splits exploded across the dark armor over the Armored Titan’s temple. The colossal figure staggered sideways, one knee hitting the earth with a impact that knocked Pieck, watching from a safe ridge, off her feet.

Silence, except for the hiss of steam.

The Armored Titan’s hand came up to its cracked skull. Reiner’s face emerged again, not from the nape, but pushing through the damaged plating near the jawline, his expression one of stunned approval. “Okay,” he called out, his voice raw. “That’s more like it.”

The Guardian Titan looked at its own fist, the white knuckle-plates steaming slightly from the transfer of kinetic force. Aria felt a surge of something hot and terrible in her chest—not pride, but a frightening recognition of the power she’d just uncorked. She could feel the ghost of the impact reverberating up her own human arm.

“Show-off,” Porco’s voice crackled from a nearby loudspeaker. He was on observation duty today, his Jaw Titan unsuitable for this kind of brute-force drill. “Took you long enough. My turn next. Let’s see that fancy sword work.”

From the ridge, Pieck brushed sand from her pants and gave a slow, steady clap. Her smile was small but genuine.

The release was intoxicating. For weeks, the training had been theory, form, controlled exercises. This was the first time she’d been told to truly hit, without the mental cage of her old humanity’s limits. The fracture in Reiner’s armor was a tangible result. It was also a door swinging open onto a dark room.

As the Titans dissolved into swirling plumes of vapor, Aria collapsed onto the hot sand, her human body slick with effort and regeneration steam. The borrowed training clothes—lightweight, tan fabric so different from Survey Corps greens—were soaked through. Reiner landed nearby with a grunt, rubbing his own temple where a fresh bruise was already flowering beneath the skin.

“Good,” he repeated, handing her a canteen. “That’s the baseline. Now we know what a full-powered defensive strike can do.”

“It felt…” Aria searched for the word, water dripping down her chin. “Unfiltered.”

“That’s because it was.” Pieck said, joining them, her gait slightly uneven. She sat in the sand with a grateful sigh. “You’ve been filtering everything through a ‘human soldier’ manual. That manual is obsolete. Your body knows what to do. You just have to stop arguing with it.”

Aria thought of the laughing memory Bertholdt had cherished, the one of her in the embroidered blouse. That girl felt like a construct now, a pleasant mask worn during quiet moments in the sunny courtyard. This—the sand, the steam, the echoing crack of fractured armor—this felt increasingly, terrifyingly real.

Porco jogged up, kicking sand at them. “Great punch. Terrible footwork. You left your whole left side open for a full three seconds. If I’d been in the Jaw, I’d have taken your ankle tendon and had you on the ground before you finished your follow-through.”

“Noted,” Aria muttered, but she was listening. His critique was tactical, professional. It was a language she understood.

“Tomorrow, we work with the blade,” Reiner said, stretching his shoulder with a pop. “Defensive arcs, controlled cutting power. The Warrior candidate cadets will be observing. They need to see what a fully realized Titan looks like.”

The word ‘Warrior’ still sent a jolt through her. It was their term for what she was becoming. It felt alien, heavy with a history she’d only been given the sanctioned, Marleyan version of.

“Will Zeke be there?” she asked, trying to sound casual.

Reiner and Porco exchanged a glance. “The War Chief is… preoccupied with the Middle Eastern front,” Reiner said carefully. “But he’s been briefed on your progress.”

There was always a careful dance around the subject of Zeke Jaeger. He was their commander, the Beast Titan, a figure of distant, analytical authority. His absence was a constant, and his interest, when expressed, felt more like a scientist reviewing data than a comrade offering guidance.

As they trudged back toward the concrete barracks, the sea wind cutting through the heat, Aria’s mind drifted back across the water she could smell on the air. She wondered what cleaning ritual Levi was performing right then. Polishing gear. Scrubbing a floor. Methodically erasing the messy, complicated fact of her from the world’s surface.

Her fist clenched at her side, the knuckles still humming with the phantom power that had cracked Reiner’s armor. She was learning to hit. She was learning to stand her ground.

But a part of her, the part that still remembered the smell of aged parchment and a dimly lit war room, knew the most difficult clean-up was yet to come. It was waiting for her, on the other side of the ocean, in the flint-grey eyes of a man who believed in finishing the job.

It was waiting for her, on the other side of the ocean, in the flint-grey eyes of a man who believed in finishing the job. The wind shifted, carrying the salt of that ocean and the sharper, newer scent of cordite and panic. It was no longer a distant thought.

Chaos was a sound. It was the layered, rising scream of a city realizing it was already dead. It was the concussive whump of thunder-spear detonations, the brittle crack of artillery, and underneath it all, the steady, grinding tremor of titan footfalls. From her vantage within the Guardian’s crystalline nape, Aria saw Liberio’s festival become a painting of gore and crumbling brick.

Her orders had been clear: perimeter defense of the internment zone’s western flank. A holding action. The Guardian was not a spear; it was a shield. She stood immobile as a statue amidst the pandemonium, her opalescent white armor reflecting the orange bloom of distant fires. The massive, sleek blade in her hand hummed, a low note felt in the teeth.

To her left, the Cart Titan, laden with weapon pods, scrambled with rodent-like agility over a collapsed tenement, its long tongue lashing out to harry the darting, wire-swinging figures in green. To her right, the Jaw Titan was a blur of feral motion, a gold-and-black streak tearing through stone and flesh in pursuit of something fast. The Beast Titan was elsewhere, a commander’s calculated absence.

Her entire world narrowed to the center of the ruined outdoor amphitheater. There, steam rising from shredded skin, stood the Attack Titan. Its familiar, brutal lines were etched against the smoke. It was grappling with something new, something monstrous and crystalline—the Warhammer. But Aria didn’t see the enemy Titan.

She saw the boy inside. She saw the relentless, vacant fury in those eyes she once knew. Eren.

Her mind fragmented. It was a plate dropped on stone, each shard a cutting thought. They’re here. The Scouts. Paradis. Levi. He’s here. He has to be. The logic was inexorable. If Eren was the vanguard, Levi was the scalpel. He would be in the city, right now, moving through the carnage with that terrifying, silent efficiency. He would be cleaning up.

A tremor, fine and human, traveled up her spine within the titan’s core. She did not move. The Guardian defends. It

The Guardian defends. It did not initiate. That was the core programming, the instinct Marley’s drills had honed into a reflex. Aria held the line, a white bastion amid the brown smoke and red mist. Her Titan’s head turned with a smooth, mechanical whir, tracking the trajectories of the green-clad soldiers swinging through the air on metal wires.

They moved like insects, but lethal ones. She saw a formation break apart, re-coalesce, driving toward the titanic struggle in the amphitheater. A coordinated feint. Her analytical mind, the one Levi had valued, automatically mapped their probable vectors.

A voice crackled in her ear, the small receiver embedded in her Titan’s flesh. “GUARDIAN, YOUR SECTOR IS CLEAR. PIVOT AND SUPPORT THE JAW’S PUSH ON THE EASTERN APPROACH.” It was Reiner, breathless, the roar of his Titan underpinning the transmission.

She opened her mouth to respond, to say ‘acknowledged.’ The sound that emerged was a guttural, vibrational hum the Titan produced for communication. But her eyes, human and wide within the steaming cavity, remained locked on a specific figure.

He was a dart of black and green, faster than the others, moving not with wild abandon but with a terrifying, economical precision. He didn’t waste gas. He didn’t waste motion. He used the crumbling architecture as a series of calculated steps, each launch propelling him toward a new vantage, a new angle of attack on the periphery of the main fight.

Levi.

He moved exactly as she remembered, yet somehow more. It was like watching a predator stripped of all camouflage, operating in its purest form. He banked off a collapsing chimney, blades a silver flicker in his hands as he severed the cables of a Scout who’d ventured too close to the Cart’s line of fire. The soldier plummeted. Levi didn’t watch them fall. He was already gone, a ricochet of violence.

“GUARDIAN, RESPOND.” Reiner’s voice was sharper now, edged with battle-stress.

Her Titan’s head swiveled toward the eastern approach, obeying the order. The massive white legs tensed to push off. But inside, Aria was screaming. A silent, airless scream that filled the hollow of the Titan’s core. He was right there. Alive. Real. Cutting his way through her new world.

“On it,” she finally whispered into the mic, the human words absurdly small.

As the Guardian Titan launched into a bounding run toward Porco’s position, the ground shuddering with each step, Aria kept her true focus on the shrinking figure behind her. He was a speck now, converging with another group of Scouts. Her mind, the lieutenant’s mind, supplied the tactical data: they were flanking. They were aiming for the Warhammer’s vulnerable tether. Levi would be the tip of that spear.

The eastern sector was a maelstrom of the Jaw Titan versus a swarm of agile attackers. Porco was a whirlwind, but he was being delayed, harried. The Guardian landed between him and a fresh squad of Scouts, its arrival a seismic event. The blade came up, not to strike, but to bisect the space between them, a warning line of humming light drawn in the air.

One Scout, young and furious, misjudged the reach. He swung too close. The Guardian’s free hand moved, not with a fist, but with an open-palmed, sweeping backhand. It was a dismissive, brutal gesture, like shooing a fly. The impact against the Scout’s body wasn’t the crack of armor, but a wet, dense thud. He caromed off a broken wall and didn’t move.

Aria tasted bile in the back of her throat. She hadn’t meant to hit him that hard. The power was so difficult to gauge.

“THANKS FOR THE ASSIST, PRINCESS,” Porco’s voice growled from the Jaw’s maw, dripping with sarcastic gratitude. He launched past her, seizing a Scout mid-swing and ending them against the ground. “NOW LOOK ALIVE.”

She forced her focus outward, becoming the bulwark. She deflected a volley of thunder-spear launches with a broad, flat sweep of her blade, the explosions blossoming harmlessly against the energy field. She was effective. She was monstrous. She was doing her job.

And through it all, a single, traitorous thought looped: He saw me. Did he see me?

Levi’s world had compressed to a tunnel. The objective: the crystalline titan connected to the ground by a umbilical of hardened material. Eren was locked with it. The path was through chaotic streets, through Warrior backup, through hell itself. He moved, and people died. It was arithmetic.

He landed on a half-collapsed bakery roof, the scent of burnt bread and blood rising. He scanned. His squad was holding, barely. His eyes, constantly cataloging threats, caught the motion at the edge of the eastern sector. A new Titan, white as a sun-bleached shell, landing with fluid grace. It moved to support the frenzied Jaw. Defensive positioning. A guard dog.

Something snagged in his assessment. The way it moved. It wasn’t the frenetic aggression of the Jaw or the brute force of the Armored. It was measured. Controlled. It used that strange blade not to chop, but to interdict, to control space. It backhanded a Scout with a motion that was almost… reluctant.

He dismissed it. A new Warrior model. Another variable to eliminate later.

He pushed off, heading for the Warhammer’s tether. Then the white Titan turned. The late afternoon sun caught the opalescent plating on its head, the visor-like face. For a fraction of a second, as it tracked the Jaw’s movement, its profile was clear.

Levi’s boot slipped on a broken tile.

He caught himself instantly, heart hammering against his ribs not from exertion, but from a violent, impossible recognition. It was an echo, a ghost cast in thirty-foot-tall, glowing crystal. The set of the shoulders. The way the head tilted just so when assessing a threat. It was the posture of a subordinate waiting for an order, scaled up to a nightmare.

Bertholdt’s memory flashed in his mind, delivered through Armin’s hesitant report. A smiling girl in an embroidered blouse.

The white Titan lunged forward, placing its body as a shield between the Jaw and a concerted attack from three Scouts. It took the hits, the explosions blooming against its chest plate, and didn’t retaliate. It just held the line.

Levi didn’t believe in ghosts. He believed in evidence. He believed in the messy, tangible truth left behind. And the truth, the one he’d buried in the forest and which was now standing in the ruins of Liberio, was that the Guardian Titan fought like her.

It fought like Aria.

A thunder-spear detonation rocked the street near the Warhammer, yanking his focus back. The tactical imperative screamed at him. The moment shattered. But the crack in his reality remained, a fissure spreading through the foundation of everything he knew.

He shot his anchors, gas jets flaring. He had a mission. He had a Titan to kill.

But as he flew toward the crystalline target, a cold, surgical part of his mind opened a new file. It was labeled not with a question mark, but with a certainty that chilled him more than any winter wind.

The clean-up had just gotten exponentially more complicated. The asset was operational. And it was in his way.
