The portal pulsed like a heartbeat, its edges tearing at the fabric of the city. Sparks of crimson energy rippled across shattered streets, and the air tasted metallic, heavy with the scent of ozone and blood. Sarah stood at the epicenter, her crimson-lilac aura blazing like a storm contained in a single body. Proto-Ascension thrummed in response, weaving through her veins and extending into her harem like a living, sentient net of force.
Akeno's fingers traced a slow path along Sarah's shoulder, sending shivers down her spine that were immediately converted into offensive resonance. "I like the chaos," she whispered, her voice intimate yet commanding. "It suits you… and us."
Rias pressed closer, guiding Sarah's focus with a steady hand at her waist. "Remember, he's fast. Calculated. And ruthless."
From the portal emerged the Chainsaw Man's true form—larger, wilder, teeth glinting like molten steel, blades for arms spinning with manic intent. Blood, both real and conceptual, pulsed along his edges, dripping into the streets but leaving no mark, as if he existed partially out of phase with reality itself.
Koneko tensed, coiling like a spring. "We face him head-on?"
Rossweisse's eyes narrowed as she stabilized the shifting gravity around them. "We need to force him into our lattice first. Phase 3 resonance must stay uninterrupted."
Xenovia readied her blade, slicing through distorted air where shards of reality tried to fragment. "Then we make him dance."
Sarah exhaled, letting the harem's energy flood her. Each touch, each subtle brush, each synchronized breath amplified Proto-Ascension beyond the previous limit. Waves of red-lilac energy rippled outward, restructuring the immediate reality. The hybrid entity staggered as the lattice imposed a rhythm on his chaotic movement.
Akeno pressed close again, lips brushing Sarah's ear. "Every heartbeat, every shiver… weaponized. Let's remind him who owns this world." Her hand traced down Sarah's side, sending desire into a vector that exploded into the lattice like lightning.
The Chainsaw Man roared, spinning chainsaw arms slicing arcs of pure force through the warped streets. But every strike met preemptive resistance: the harem's synchronized positions projected energy shields, converted attacks into redirected force, and launched devastating countervectors.
Koneko leapt, striking the hybrid with bone-crushing density. Rossweisse stabilized the spatial collapse while Xenovia's blade cut with surgical precision. Rias reinforced the lattice with each subtle pressure of her hand, and Akeno amplified emotional vectors through deliberate frôlements.
Sarah stepped forward, her aura pulsing in tandem with her heartbeat. Proto-Ascension flared into a radiant storm, every thread of desire, every touch of trust, every glance a weapon and shield at once. The Chainsaw Man faltered, his attack pattern disrupted, the hybrid's wild rotations staggered.
Lilith Fragment's consciousness whispered inside Sarah's mind: Phase 3 full activation possible. Harem synergy exceeding all previous metrics. Offensive potential… critical.
Sarah smiled faintly, feeling the surge of raw energy convert into precision. "Then we push. Together."
The hybrid recoiled as Sarah's aura expanded violently, threads lacing through her harem. Each touch and brush of desire became an amplified vector. The city warped under the pressure, streets curling, vehicles lifted and suspended mid-air, yet the lattice remained intact.
Akeno's lips brushed Sarah's again, teasing and electric. "I think he's starting to understand… resistance is useless."
Rias whispered against her shoulder, "Keep your focus. Phase 3 can't be broken, not yet."
Koneko smashed through an incoming blade, Rossweisse redirected residual energy streams, and Xenovia cut with exacting efficiency. Proto-Ascension pulsed outward, compressing the hybrid's chaotic energy and forcing it into disarray.
Sarah's heartbeat became the metronome of the battle. She advanced, hands trailing along her harem in deliberate frôlements, and the hybrid staggered under the combined weight of synchronized desire, precision, and Phase 3 conceptual mastery.
With a final, coordinated surge, the lattice expanded in a radiant explosion of crimson-lilac energy. The Chainsaw Man's form fractured under the overwhelming force, chainsaw blades spinning uselessly before shattering into conceptual shards absorbed by Proto-Ascension.
The portal pulsed one last time, stabilizing slightly, acknowledging their dominance. Sarah's aura glowed brighter, threads of desire and power stretching into the city sky like a promise of unshakable control.
Akeno smirked, brushing Sarah's arm, eyes glinting with mischief and fire. "And that… was how we greet new worlds."
Rias exhaled, her hand still pressing against Sarah's chest. "This doesn't end here. Others may follow."
Sarah's eyes burned with determination. "Then we'll be ready. Always."
The city trembled under the aftershocks, reality warping slightly under the Proto-Ascension's residual energy. The real-world crossover had begun. And nothing, not even the laws of the universe, would remain unchanged.
