My Overpowered Bunny Girls

The TCA Archives were entombed deep beneath the bedrock of the capital.

Nathan followed Helena down the spiraling, claustrophobic throat of ancient grey stone. With every rotation of the staircase, the ambient temperature plummeted, the chill biting through their combat-worn gear. The vanguard followed in absolute silence—Garrett’s heavy footfalls echoing off the masonry, Dillon unusually subdued, Elise walking with rigid, academic posture, and Smithy trailing at the rear, a reluctant ghost among the living.

His three summons rode with him in their base forms, Mirko rested on his shoulder, her ears twitching at the subtle shifts in air pressure. Kuro was a pocket of absolute darkness tucked into the folds of his jacket. Shiro sat perched atop his head, her golden eyes sweeping the descending gloom with the regal, unblinking focus of an apex predator evaluating a new territory.

"These vaults house every fragmented piece of data the TCA has ever compiled regarding the Tower Worlds," Helena’s voice drifted back to them, echoing hollowly off the curved walls. "Some of these codices date back two centuries, to the very first dimensional incursions. But the vast majority of this wing hasn’t been breached in decades."

"Why let it rot?" Garrett’s deep baritone broke the quiet. "Intel is ammunition."

"Because the overwhelming majority of Climbers never break the threshold of Master Class," Helena replied, halting before a massive, circular vault door forged from heavy, runic iron. "And the handful who do... rarely return to give their after-action reports."

She pressed her bare palm against a recessed mana-lock. The ancient mechanisms recognized her genetic signature.

CLACK-WHIRRR-HISSS.

The pressurized seal broke, venting a cloud of stale, freezing air as the iron door groaned open on neglected hinges. "The TCA permanently suspended sanctioned expeditions into Master Class Tower Worlds after the casualty rates became mathematically unsustainable. The intelligence in here transitioned from tactical briefings to academic theory. Dust and ghosts. Until you survived the Ashen Expanse."

The chamber beyond was cavernous, swallowing the meager light of the hallway. Towering, monolithic shelves stretched into the dark, burdened with decaying vellum scrolls, leather-bound bestiaries, and dormant, glowing data crystals. A thick, undisturbed shroud of dust coated every horizontal surface. The air smelled of dry rot, cold stone, and the ozone tang of sleeping magic.

"The Verdant Depths," Nathan said, his voice dropping into the quiet of the tomb. "What exactly are we walking into?"

Helena navigated the labyrinth of shelves with practiced familiarity, eventually dragging a massive, steel-reinforced binder from a lower rack. THUD. She dropped it onto a scarred reading table, sending a plume of dust dancing into the ambient light.

"This is the entirety of our operational intelligence," she said grimly. "It isn’t much. The Verdant Depths was first cataloged roughly a century and a half ago. A Master Class dimensional space, operating on the same tier as the Ashen Expanse. But where the Expanse was defined by absolute, necrotic stagnation, the Depths are the exact opposite. It is alive. Aggressively, terrifyingly alive."

She threw the binder open.

Inside were hastily sketched topographical maps, charcoal renderings of bizarre, asymmetrical bio-forms, and pages of cramped, frantic field notes. Nathan leaned over the parchment, his newly forged B-Rank eyes effortlessly translating the faded ink in the gloom.

"The final TCA expedition to successfully breach the Verdant Depths deployed exactly thirty years ago," Helena continued, her voice devoid of inflection. "A coordinated raid. Four elite parties. Twenty Master Class Climbers." She tapped the faded parchment. "Only three extracted. And they were... fundamentally altered."

"Altered how?" Dillon asked, stepping closer, the ambient static from his boots completely suppressed by the oppressive atmosphere.

"The medical logs state they were covered in a parasitic overgrowth when they materialized on the extraction pad," Helena said softly. "Living, violently green vines physically threading through their vascular systems, bursting from their pores and tearing through their armor. They suffocated within seventy-two hours. But before their lungs filled with blooming flora, they gave their debriefs."

She met Nathan’s gaze. "They described an ecosystem where the cellular division never ceases. Where the very trees shift their roots to hunt. Where the blossoming flowers emit a siren’s song of bio-magical spores that rewrite a Climber’s nervous system. And where something massive, ancient, and deeply furious in the abyssal ocean was screaming for them to drown."

The silence in the Archives became suffocating. Nathan physically felt his summons react through the newly widened channels of their neural link.

’A biome of overwhelming, unchecked vitality,’ Kuro observed, her mental projection a surgical dissection of the intelligence. ’The Pale Shepherd did not corrupt this world with death. He weaponized its own life cycle. Cellular growth without biological limitation is not an ecosystem. It is a cancer.’

’The Young Lord must tread with absolute caution,’ Shiro added, her formal tone vibrating with draconic wariness. ’Life completely stripped of the natural cull of death ceases to be balance. It becomes absolute, suffocating consumption.’

Nathan turned the brittle pages. He found a series of charcoal sketches detailing massive, floating terrestrial islands, leviathan shadows suspended in deep water, and humanoid figures possessing sleek, amphibious anatomy—gilled throats and webbed, elongated extremities.

"The Tidecallers," Nathan murmured, running a finger over the sketch. "Smithy mentioned them during the interrogation."

"The indigenous sentients of the Verdant Depths," Helena confirmed, tracing the margins of the text. "According to the fractured accounts of the survivors, they are an ecclesiastical matriarchy—a priestess order that communes directly with the abyssal ocean. They were actively waging a war of attrition against the parasitic overgrowth, attempting to violently prune the world back into balance. But they were losing ground."

Nathan closed the heavy binder. THUD. "Then we have our vector. The Verdant Depths is the next coordinate in the Shepherd’s sequence. If we can breach the canopy, secure the Tidecallers, and purge the overgrowth, we rip another piece of the board away from him."

Helena’s expression hardened into an administrative mask. "The TCA High Council will not authorize another immediate deployment into a Master Class zone. The political fallout from the Ashen Expanse is still settling. Your party requires an REM cycle, physical rehabilitation, and extensive tactical debriefing. We must analyze the biomatter and intelligence you extracted."

"Then we prepare in the shadows," Nathan countered, his voice leaving absolutely no room for debate. "We dissect these archives. We adapt our combat rotations. And the exact millisecond the TCA signs the deployment orders, we jump."

Helena held his stare for a long moment before giving a single, rigid nod. "The primary breach point for the Verdant Depths is located in a hyper-saturated portal zone deep in the southern marshes. It is a three-day overland trek from the capital walls. I will require time to coordinate a multi-vanguard raid—the survivors of the Ashen Expanse, bolstered by our heaviest available reinforcements."

Nathan looked back at his bruised, veteran vanguard. They were battered, stained with the ash of the Cleansing, but the fire in their eyes was undeniable. "Then we have a window. Time to fundamentally understand the biology of the nightmare we are walking into."

He turned away from the heavy iron door and faced the labyrinth of decaying history. Somewhere hidden in this subterranean graveyard of academic theory lay the tactical edge they needed. A singular clue. A structural weakness in the Shepherd’s bio-weapon.

And somewhere far beyond the physical borders of their reality, submerged in a suffocating ocean of endless, parasitic green, the Verdant Depths was waiting to consume them.
