While Zeke enjoyed his leisurely breakfast, on the other side, Mobius was twirling her fork around the steak on her plate, humming a tune.
"Hummm~ humm-humm~"
The pleasant melody from her soft humming captivated the ears, yet its tone seemed eerily tranquil, like a venomous snake slithering silently through the night, sending chills down one's spine.
"Screech!"
The metal fork scraped against the plate with a grating noise. Mobius's gaze sharpened, her inscrutable serpent eyes shifting towards the metallic chamber occupying most of the laboratory space.
The sealed black metal door exuded a sense of immense solidity, but now, cracks were steadily spreading across it.
Mobius stared at those fissures, her small pink tongue gently licking her lips before she casually flicked her hand.
"Clack!"
"Dr. Mobius, please don't waste food or pollute the environment."
"What does it matter? Isn't Klein here to clean up?"
"Although I will indeed take care of it, sigh..."
Klein's emotionless voice ended with a weary, helpless sigh. She knew her admonishments were futile, as Dr. Mobius was inherently capricious.
Meanwhile, Mobius's curved brows and smiling eyes emitted a chilling aura of murderous intent, while beneath them surged an ambition determined for success.
"At last, the moment has arrived. Are you ready, my little lab rat? Ha ha ha!"
"Rumble!"
In the break room's sunlit outdoor café area, a sudden tremor shook heaven and earth.
"Huh?!"
The girls' expressions changed, abruptly halting their ravenous eating and chatter. All eyes turned towards Zeke, who was just about to pick up his fried egg with chopsticks.
Zeke calmly placed the fried egg in his mouth, chewing nonchalantly amidst the shaking before swallowing. He then picked up a small towel from the table to wipe his lips.
After these composed actions, he pressed one hand onto the table.
"Boom!"
Without warning, a loud noise reverberated, as if suppressing a massive earthquake-like disaster. The shaking instantly ceased, bringing tranquility back to the surroundings.
"I'll be right back," Zeke said mildly, pushing his chair back and standing up. His figure vanished without a trace.
Using the predefined virtual coordinates, Zeke teleported to Mobius's domain.
There, Mobius sat atop her signature flying device, her long dress billowing gently in the wind. Her dazzlingly white feet occasionally peeked out amidst the movement. With hands cupping her face, she gazed at Zeke with a disturbing Yandere smile.
"Hmm?"
A series of data windows appeared before Zeke's eyes. After rapidly scanning through them, he shook his head and calmly met Mobius's gaze.
Zeke said, "Dr. Mobius, as expected, you never disappoint. You truly did tamper with it."
"Oh, just some minor adjustments. So, are you satisfied?" Mobius tilted her head slightly, licking her lips, her curling smile deepening into a darker, more Yandere expression.
Behind her, the sealed metallic cabin resembled a flickering candle in the wind, riddled with cracks and constantly vibrating under internal power fluctuations.
"Boom!"
"Screech!"
As they faced off, there was first a deafening explosion as the metal cabin burst open. Then, a bloody claw emerged from Mobius's delicate waist.
"Hahaha!" Mobius erupted into laughter.
Despite blood pouring from her mouth, staining her once pristine teeth red, she spread her arms wide, exuding a proud and boastful demeanor, and cackled wildly:
"This is my masterpiece! Are you satisfied now, Zeke? Ha ha ha!"
"Hissss!"
Mobius's wild laughter was cut short as razor-sharp claws and a gaping maw made of black substance completely tore her apart. Blood, fabric, and flying device debris scattered everywhere, resembling a gruesome feast by the very monster she had created.
"Ah..."
Zeke shook his head with a soft sigh, showing no additional change in expression or movement. Instead, he quietly observed the current state of Sin.
She stood naked, her delicate and fair body exposed to Zeke. On all fours like a beast, her limbs were wrapped with clawed tendrils of a dark metallic-like substance. She raised her head, baring shark-like teeth menacingly towards Zeke.
"Huff... huff... huff..."
Sin snarled, emitting heavy breaths, and a silver drool dripped from the corner of her mouth. Upon hitting the ground, it sizzled, corroding the metal floor and leaving behind scorched marks.
But these details were insignificant. Most strikingly, a black substance covered half of her left gray eye, seemingly flowing or writhing backwards, spreading across her pristine white back. From this emerged a fearsome, tooth-filled maw and sharp claws, directed aggressively at Zeke, akin to an ominous demonic curse.
"The original sin..." Zeke stroked his chin, deep in thought.
The distorted world within Sin's almond-shaped eyes represented two aspects: first, the manifestation of humanity's dark side, and second, the imprints left by time—namely, the current distortion of her character combined with past actions and future deeds, projected collectively through the temporal dimension Sin inhabited.
Considering Dr. Mobius's entire experimental process, this monstrous dark substance likely embodied the fusion of temporal and psychic attributes' powers.
"True to form, Dr. Mobius has maximized Sin's potential..."
Zeke murmured as he watched Sin, bearing the dark monster on her back, hurtle towards him like a swift arrow, moving quadrupedally.
"Crunch!"
The sound of teeth sinking into flesh echoed.
Zeke raised one arm, allowing Sin to bite through it with her own teeth, effectively countering her attack.
However, while Sin momentarily halted due to biting down, the black creature on her back continued unabated. It opened its gaping maw filled with razor-sharp teeth from above, lunging towards Zeke's head.
"Shriek!!!"
In the break room, darkness engulfed the once-clear blue sky.
The girls fell silent, their gazes fixed upward.
"If you're not afraid of getting beaten up, come on over," Kiana said leisurely while resting her head on Raiden Mei's lap. "There are plenty of us here; we don't fear you."
Kiana possessed partial control over space, and even within the intertwined realities of the Elysian Realm, she could sense someone hiding in subspace.
Everyone followed Kiana's gaze, but as its creator, Mobius had astonishing knowledge and mastery over this domain. The girls couldn't discern any clues.
Within the void world, Mobius clasped her hands together, the jade finger guards tapping against each other with metallic sounds.
"Clack! Clack! Clack!"
"I've set some traps using Zeke's blood, which should captivate our rational yet frenzied lab rat... It'll stall the most troublesome one for now, though not indefinitely."
"I initially planned to scatter these materials across different realms, targeting the cutest one first. But he's managed to stabilize this space... Tsk! Just as expected; he was prepared all along."
"Now, facing multiple adversaries at once puts me at a disadvantage, so I must abandon my plan... Or do you think that's what I'd do?"
"How naive!"
Mobius narrowed her eyes, and the void before her shimmered, revealing the break room scene with increasing clarity.
