The city trembled beneath them, but Sarah did not falter. The portal above shimmered with unnatural light, its swirling vortex casting distorted shadows across shattered skyscrapers and collapsed streets. Proto-Ascension hummed through her veins, threads lacing outward, wrapping around her harem as if the six women were extensions of herself rather than allies.
Rias moved first, sweeping her hand over the nearest rubble to create a stabilized platform. "The ground is unstable. Every step counts," she said, voice tight. She glanced at the portal. "And whatever comes through is not going to wait for us to organize."
Akeno's touch traced Sarah's side, sending a pulse of desire into the lattice. "Then we don't wait. We push forward." Her lips curved into a smile that was equal parts teasing and dangerous. "Let them come."
Koneko crouched, tail swishing, eyes scanning every shadow. "I detect multiple vectors approaching. Speed… beyond human." Her voice was calm, almost clinical, but her muscles were taut, ready to spring.
Rossweisse extended her hands, weaving glyphs midair. Runes shivered and locked into place, reinforcing the lattice. "They're testing our cohesion. Every attack is designed to fracture us emotionally and physically."
Xenovia twirled her sword, tracing glowing patterns that reinforced Proto-Ascension's defensive layers. "Then we test them first. Pre-emptive strikes. Keep them off Sarah."
Lilith Fragment hovered above, her gaze piercing the portal. "Remember. The lattice isn't just defense. It's a weapon. Every touch, every heartbeat, every spark of desire feeds it."
Sarah exhaled slowly, letting Proto-Ascension's threads spread outward, wrapping her harem, stabilizing them, enhancing their instincts. The first wave of intruders emerged—a swarm of twisted forms, limbs jagged, teeth glinting like chainsaws, moving with an eerie coordination despite their monstrous appearances.
Akeno's fingers grazed Sarah's wrist, sending a pulse that converted emotion into kinetic force. "Let's begin."
The harem shifted in perfect synchrony. Rias's hand anchored them, Koneko intercepted strikes with raw density, Rossweisse cast stabilizing runes midair, Xenovia cut vectors before they fully formed, and Akeno amplified every emotional surge into controlled energy. Proto-Ascension flared, threads lacing outward in radiant, crimson-lilac arcs.
The first monster lunged, a blur of teeth and serrated limbs. Koneko leapt, colliding with it midair, absorbing its kinetic energy. Xenovia slashed, cutting through its trajectory, and Rossweisse's glyphs froze a section of air, slowing its advance. Akeno's touch on Sarah's side converted their collective synchronization into a backlash that sent it reeling.
Sarah struck next. Her aura surged outward in a wave of pure conceptual energy, unraveling the creature's coherence. It collapsed into a pile of fractal fragments, which dissolved into nothingness, absorbed into Proto-Ascension's lattice.
More came, faster, each attack more calculated, more adaptive. The harem moved as one, each action feeding into the next. Every pulse of desire, every brush of skin, every glance became a vector of offensive and defensive power.
The portal shuddered. A second wave emerged, larger, faster. Chainsaw teeth whirred, limbs flexing in impossible angles. They attacked not just the body, but perception itself, distorting spatial orientation, gravity, even the flow of time in the immediate area.
Rossweisse's eyes widened. "They're manipulating reality parameters! The lattice alone won't be enough to keep us coordinated."
Rias pressed her palm against Sarah's chest, anchoring her. "Then we integrate at the emotional level. Make them feel our bond."
Akeno's lips brushed Sarah's ear, sparking an immediate surge of energy. "Every heartbeat, every pulse, every glance. Let's show them what desire can do."
Koneko and Xenovia adjusted their stances, moving in tandem, striking, blocking, and countering. Rossweisse reinforced the lattice, weaving a protective web through air and concrete. Proto-Ascension flared brighter, threads spiraling outward, reacting to every intrusion before it could manifest fully.
The Chainsaw Devils adapted. They moved faster, striking at angles that tried to separate the harem, destabilize Proto-Ascension's flow. One leapt at Sarah directly, chainsaw limbs spinning, aiming to pierce her aura and strike her heart.
Akeno reacted instantly, hands on Sarah's shoulders, feeding controlled surges of Desire. Proto-Ascension twisted around the intruder like living armor, absorbing, redirecting, and amplifying. Sarah's pulse became the metronome of the battlefield, threads of her power lacing tightly with her harem.
Rias's voice cut through the chaos. "Now! Counterstrike in three—two—"
Sarah moved. A surge of energy radiated outward, threads lacing through her harem, converting fear, trust, and desire into a pulse that struck the intruders before they could complete their attack. The lattice projected force back, destabilizing the Devil midair.
Koneko launched, striking multiple targets, sending them crashing into the streets. Xenovia's blade carved through three simultaneously, their motions perfectly predicted by the lattice. Rossweisse reinforced every strike with layered runes, preventing counterattacks. Akeno's touch amplified the force exponentially.
The portal shimmered. Another wave emerged, larger, denser, faster than the last. But Sarah did not falter. Proto-Ascension responded to every movement instinctively. Threads wrapped around every harem member, converting each attack into a synchronized counterstrike.
A chainsaw limb swept toward Sarah's face. Akeno's lips brushed her cheek, sparking a pulse that deflected it. Koneko intercepted midair, spinning with raw strength. Xenovia cut the trajectory in half. Rossweisse's runes held the space together. Rias stabilized the formation.
Sarah struck outward, sending a wave of conceptual energy that tore through the intruders like a storm. They faltered, fragmented, recalibrated—but the lattice anticipated, countering every adaptation.
The city shook. Windows shattered. Debris spiraled in eddies of distorted gravity. But within Proto-Ascension's lattice, every movement was perfect, every reaction instantaneous.
The harem moved closer to Sarah, each contact amplifying the lattice. Threads laced together, weaving desire, fear, trust, and determination into a network of unstoppable force.
Akeno's whisper brushed Sarah's ear. "This… this is our moment. Every pulse counts."
Sarah's eyes glowed. "Then let's finish the wave… together."
The intruders surged, the largest yet. But as they approached, they faltered under the lattice's weight, destabilized by the combined emotional resonance of the harem. Proto-Ascension flared to maximum density, threads snapping and reforming, a living storm of conceptual energy that wrapped around every intruder, absorbing and nullifying their attacks.
Rias gritted her teeth. "Keep pressure. Don't let them regroup."
Koneko's tail lashed, striking multiple foes. Xenovia cut paths through the air, severing limbs mid-swing. Rossweisse's glyphs stabilized collapsing streets, keeping every member coordinated. Akeno's touches amplified every pulse.
Sarah let the lattice surge, pushing Proto-Ascension to a new peak. Desire, trust, fear, all converted into pure energy, radiating outward.
The portal shuddered violently. Another figure emerged—larger, slower, more intelligent, its chainsaw teeth glinting with focused precision. It was not a mindless attacker but a hunter, analyzing patterns, seeking weakness.
Sarah's lips curved. "So it's a leader."
Akeno pressed against her side, lips brushing again. "Then we'll teach it manners. Together."
Proto-Ascension expanded, threads lacing tighter, lattice shimmering with crimson-lilac energy. Every movement, every touch, every glance amplified, forming an impenetrable vector.
The city trembled, buildings groaned, streets fractured—but inside the lattice, every action was precise, controlled, unstoppable. The first arc's final conflict had expanded across worlds, but Sarah's resolve, amplified by her harem, could face anything.
And as the Chainsaw leader approached, analyzing, adapting, calculating—it was already too late.
The lattice had become a storm.
A storm no intruder could survive.
