The portal had not closed.
It hovered silently above the fractured city, a yawning rift in reality, faintly humming with the echo of worlds not meant to touch one another. Crimson-lilac threads of Proto-Ascension coiled and flexed around Sarah, sensing the anomaly as both threat and opportunity. The harem's combined presence gave her center of gravity, her anchor—but even together, the air felt thick with tension, the weight of observation pressing down from a reality beyond their own.
Rias stepped forward, her boots crunching over fractured concrete. "We need to understand what's on the other side," she said. "If that portal remains open, the consequences could be catastrophic."
Akeno's hand grazed Sarah's side, sending an electric pulse through Proto-Ascension's lattice. "I agree. But we aren't just investigating. We're being watched—and evaluated." Her tone carried an edge of playful warning, but there was steel behind it, a reminder that every touch, every reaction could be weaponized.
Koneko crouched low, tail swishing, muscles coiled like springs. "Then let's move carefully. Any movement could trigger something."
Rossweisse extended her hands, weaving stabilization runes in the air. "I've detected residual energy signatures emanating from the portal. They're unstable, chaotic, but patterned. Someone—or something—is guiding them."
Xenovia's sword was already drawn, the tip gleaming as she traced a circle around Sarah. "Guided or not, we'll face it together."
Lilith Fragment hovered above, her gaze fixed on the portal. "Whatever comes through… it won't be subtle. Phase Three has drawn attention from beyond the Origin Layer."
Sarah exhaled slowly, letting her aura stabilize around them. Proto-Ascension pulsed, a living network that bound them all, weaving desire, fear, and trust into a lattice that could withstand immense pressure. The harem felt the surge instantly, aligning instinctively, every pulse in perfect resonance.
She looked up at the portal. From its swirling depth, faint shadows moved—indistinct at first, then gradually coalescing. They were humanoid, but wrong, distorted, like reflections in broken glass. Their forms flickered in and out of coherence, limbs bending in ways that should have been impossible, faces twisted into expressions of hunger, pain, and malicious curiosity all at once.
Akeno's lips curved into a teasing smile. "Well, at least they're polite enough to arrive in formation."
Rias shook her head, brow furrowed. "This is serious. They're not hybrids like before. They're—" She hesitated. "They're from that other world."
Koneko's ears twitched. "Chainsaw shapes."
Rossweisse's eyes widened. "You mean… Devils?"
Xenovia's grip on her sword tightened. "Then we're dealing with a completely different level of threat. Not just testing us, observing us… but hunting us."
Lilith Fragment's voice was sharper than any blade. "Exactly. And Sarah, your lattice will be the first target. They sense the Seed."
Sarah's fingers flexed, and a pulse of Proto-Ascension surged outward, lifting debris and creating a protective aura. Her harem mirrored her movements instinctively, forming a rotating shield of offense and defense. Every touch, every glance, every breath amplified the lattice, converting emotional resonance into pure conceptual force.
From the portal, a single figure stepped forward—taller than a man should be, its body shifting with mechanical fluidity. Chainsaw teeth glinted along its arms, slicing through the air like whispers of violence. Its head, a grotesque fusion of human and machine, rotated as if evaluating them, the hum of its motorized parts vibrating the ground beneath them.
Akeno's hand slid along Sarah's side again, a small but deliberate spark of Desire feeding Proto-Ascension's responsiveness. "Oh… this one's curious," she murmured, a dangerous edge to her tone. "Curiosity doesn't usually end well."
The Chainsaw Devil growled, and the sound was not sound. It was vibration, a conceptual threat that reached into the mind, brushing against the edges of perception, probing, testing, measuring.
Sarah's eyes narrowed. Proto-Ascension flared in response, threads wrapping around her harem like a protective storm. Every pulse, every touch, every subtle interaction became a vector of power, transforming the conceptual threat into energy that strengthened the lattice.
Rias pressed her palm to Sarah's chest. "It's not just attacking. It's testing the bonds. Make sure you stay connected. Don't let it divide us."
Koneko leapt forward, landing between a projected attack and Sarah, absorbing the brunt of a strike that bent gravity around her. Her tail lashed, knocking debris aside, and she landed lightly, eyes fixed on the approaching enemy.
Rossweisse cast stabilizing runes around the group, the glyphs humming with power, preventing the spatial distortions the Devil attempted to impose. "It's not just physical," she shouted. "It's trying to manipulate the very parameters of our formation!"
Xenovia's blade cut through the air, tracing symbols that reinforced the lattice's defensive vector. "Then let's show it what a coordinated harem can do!"
Akeno's lips brushed Sarah's ear, her voice low. "Every heartbeat, every pulse… our emotions are our weapons now."
Sarah's aura surged outward, threads lacing tightly with each member of the harem. Proto-Ascension responded automatically, adapting to the Chainsaw Devil's attacks before they fully manifested. The lattice did not just defend—it projected force back, rewriting the assault into defensive energy, destabilizing the Devil's advance with every interaction.
The first clash erupted. The Chainsaw Devil lunged, a flurry of motorized teeth and mechanical limbs slicing through reality, each strike designed to separate, to destabilize, to isolate Sarah.
Koneko intercepted, limbs absorbing impact with raw force. Xenovia struck, carving lines of energy that disrupted the Devil's path. Rias stabilized the formation, reinforcing every connection. Akeno's Desire amplified, converting emotional charge into a shockwave that threw the Devil slightly backward. Rossweisse's runes kept the surrounding space coherent, preventing further distortion.
Sarah stepped forward, Proto-Ascension flaring like a storm, threads wrapping tighter, pulses converting into directed energy. She did not just strike. She issued a command.
The lattice responded.
The Devil faltered.
It recalibrated.
Then it leapt back, spinning in midair, teeth whirring, its mechanical body attempting a multi-vector strike designed to overwhelm their synchronization.
Akeno gasped, lips brushing Sarah again, sending an immediate surge of energy through the lattice. "Hold on—push back!"
Sarah's pulse accelerated, Proto-Ascension threads tightening to maximal density. Every harem member acted as an extension of herself. Every glance, every brush of skin, every subtle movement reinforced the network, converting the Devil's attack into a pulse that sent it skidding backward, its mechanical body sparking with overload.
Rias's voice was sharp. "We can't let it recover! Keep the pressure on!"
Koneko lunged, landing multiple concentrated strikes on the Devil's limbs, destabilizing its balance. Rossweisse cast a series of layered runes that locked the surrounding space into temporary stasis, slowing its readjustments. Xenovia sliced through the air, each cut precise, reinforcing the lattice.
Sarah moved like a singularity of power, her body a conductor for Proto-Ascension's full force. Every strike amplified, every counter reinforced. Desire, fear, trust, emotion—all became weapons.
The Chainsaw Devil staggered, then fell, not destroyed but contained, forced backward into the portal. Its movements were slowed, recalibrated, constrained by the overwhelming lattice.
But as it vanished, the portal shuddered, expanding slightly, a second figure stepping through almost immediately—a smaller, faster, more erratic form. Its movements were chaotic, unpredictable, jagged, but it carried the same intense observation, the same hunger.
Sarah's lips curved. "So… it's not done."
Akeno's hands slid along her sides, precise, feeding Proto-Ascension with controlled bursts of Desire. "Good. Then we'll teach it manners."
Rias's hand pressed firmly to her chest. "We adapt again. Keep the formation tight."
Koneko leapt, Rossweisse stabilized, Xenovia struck, Akeno amplified—and Sarah flared. Proto-Ascension exploded outward in waves, threads lacing tighter, synchronizing every harem member into a single offensive vector, every strike converting emotion into force.
The second Devil faltered—its erratic movements slowed, destabilized, overwhelmed by the lattice's resonance.
Lilith Fragment's voice flowed inside Sarah. Phase Three is active. Emotional integration exceeds parameters. They cannot divide you. This is your evolution.
Sarah smiled faintly. "Then let's evolve together."
The harem pressed forward in perfect synchronization, Proto-Ascension a living storm, every strike, every movement amplified, each connection a node of unyielding force.
The portal flickered. The city trembled.
The first arc's final confrontation had expanded into a new battlefield, one that crossed worlds, realities, and intentions.
And Sarah… she was ready.
