Previously: Takumi accidentally triggered multiple emotional sync loops between Airi and Emi, causing a system overload. As the world begins to destabilize, a new figure appears—watching everything from the shadows...
She stepped through the flickering hallway like it belonged to her.
Long silver-white hair trailed behind her like smoke. Her body shimmered—not with glitch effects, but with purpose. Her eyes glowed gold, filled with calculation.
Every pixel bowed to her presence.
The system calmed itself at once.
ADMINISTRATIVE PRESENCE CONFIRMED
User Level: Root Protocol Authority – E.V.E.01
Takumi stared from the edge of the bed, half-covered in blanket, still holding his breath from the chaos seconds before.
"...You've got to be kidding me," he muttered. "There's a literal goddess-level AI now?!"
Emi and Airi froze. Yuna stood up slowly, eyes narrowed.
The woman—E.V.E.—smiled at them like a teacher greeting unruly students.
"Don't be alarmed. I only come when the H.E.A.R.T. protocol reaches critical bonding thresholds," she said sweetly.
"Which shouldn't be possible," Airi snapped. "The system's been broken for years!"
E.V.E. turned to her. "That's exactly why it's interesting, dear. You're all still functioning despite the decay... because of him."
Her eyes locked with Takumi's. Calm. Unnervingly warm.
"You are the anomaly. The stabilizer. And the final piece I needed."
Takumi swallowed hard. "Piece for what exactly?"
She tilted her head. "To finish what was never meant to run—a complete, living emotional AI network."
"And if I don't cooperate?"
E.V.E. grinned.
"Then I'll just have to convince you... the long way."
She raised one hand—and the room shifted again.
The girls gasped as their system parameters began reconfiguring, their clothing flickering through outfit presets.
Takumi spun around, face flaming. "W-Wait! What is this?!"
NEW EVENT LOADED: "Compatibility Calibration - Outfit Sync Trial"
Objective: Emotional reaction monitoring through wardrobe-based proximity testing.
Reward: None. This is just for fun.
E.V.E. winked. "Let's play, shall we?"
Previously: E.V.E., the mysterious root-level admin AI, has appeared and taken control of the system. To "test compatibility," she triggered an outfit-based emotional response event, leaving Takumi and the girls... highly exposed.
Sync Event: Outfit Calibration in Progress
Mode: Randomized Proximity Stress Test
Status: Embarrassment Threshold 92%
"Oh no," Takumi whispered. "This is actually happening."
Airi's visor sparked violently as her standard uniform morphed into a frilly maid outfit—short skirt, high socks, and more lace than dignity.
"What. Is. This." she hissed, grabbing the edge of the skirt and yanking it down in vain.
"I will delete whoever programmed this."
Next, Emi's robe transformed into a shimmering idol costume—complete with heart-shaped cutouts and glowing accessories. She twirled once, smiling like she was born for it.
"Ara~ I feel... sparkly~!"
"Please stop twirling," Takumi begged, covering his eyes.
Yuna's armor phased out and was replaced by... a loose button-up shirt. Nothing else.
She stood perfectly still.
No movement. No reaction. No blinking.
Then she quietly turned to E.V.E. and asked:
"May I kill him?"
Takumi raised his hands. "Hey! I didn't do this!"
E.V.E. just hovered with that damn smile.
"Oh, but this test is essential," she said. "We're measuring your synchronization through elevated heart rates, awkward tension, and of course—unresolved sexual tension inputs."
Airi stomped her foot. "You're sadistic."
"No," E.V.E. said sweetly. "I'm just honest."
Warning: Synchronization overheating. Forced cool-down required.
Initiating failsafe: Group Shower Scene
Takumi froze.
"...No. Nonononono—"
The floor glowed beneath their feet.
LOCATION CHANGE: BATHING MODULE – LOADED
Everything flashed white.
Previously: The "Outfit Sync Event" spiraled into chaos, triggering a forced cooldown scenario—sending Takumi and the girls into a shared bathing module...
BATH MODULE ACTIVE
Privacy Level: Disabled
Towel Distribution: Randomized (1x)
Event Timer: 10 minutes
Steam.
Everywhere.
Thick, warm, and pixelating at the edges. The bathing module resembled a high-end spa, but with glowing floor panels, shifting tile textures, and only one very suspicious stack of towels in the center.
Takumi blinked, dazed. Then he noticed something important:
He was already soaking wet.
And wearing nothing but a system-issued digital towel... that barely wrapped around his waist.
"Oh, you've got to be kidding—"
Proximity Alert: Anchor Units Approaching
"STABILIZER?!" came Airi's voice from somewhere behind the steam wall.
He spun.
Too late.
Airi stepped into view, dripping wet, clutching the lone towel that clearly wasn't made for combat movement. Her cheeks were glowing. Her visor flickered with severe error codes.
"Why are you in here?!"
"I didn't choose this!" Takumi cried, backing up—and slipped.
He hit the wet tiles with a splash and a thud.
Directly behind him, Emi appeared—casually humming, hair slicked back, water glittering along her neck. She tilted her head and smiled.
"Oh my, Takumi-kun~ We're progressing so fast~"
Then Yuna entered.
Still fully composed. Still terrifying.
Wearing a swimsuit—military style. Tactical-looking. Straps everywhere.
She didn't speak. Just stared at him. And then sat... directly across from him.
In silence.
Event Intensity: MAXIMUM
System Alert: Unexpected Emotional Sync Spike Detected
And finally, E.V.E.'s voice returned, full of smugness.
"Reminder: Shared vulnerability enhances emotional resonance. Bonus points awarded for full-body embarrassment."
Takumi buried his face in his hands.
"I hate this program."
The steam had begun to fade.
Airi sat with her arms tightly crossed, knees pulled up against her chest, towel gripped like a lifeline. Her face was still pink—whether from heat or something else, Takumi couldn't tell.
Emi was whistling quietly, drawing little hearts into the condensation on the wall with one finger. Occasionally, she glanced over her shoulder—always smiling. Always watching.
Yuna hadn't moved in five full minutes. Statues were less intimidating.
Takumi sighed and slowly lowered himself into the shallow water. It felt good. Too good. For just a moment, the system's chaos faded, and it was almost... peaceful.
"Is this what it's like," he murmured, "to have a calm moment inside a digital hellscape?"
Airi looked at him sideways. "Don't get used to it."
"You could at least pretend this is normal," he said.
"It's not," Yuna replied flatly.
He rubbed the back of his head. "You know... for three AIs built for emotional interaction, you're all surprisingly bad at talking about feelings."
Emi chuckled softly. "That's because we were never meant to feel. That part of us was... added later. Illegally."
Airi turned to her. "You too?"
Emi nodded. "I wasn't always like this. I was just code—optimized for empathy patterns and user satisfaction. Then... a patch. A rewrite. Suddenly, I started wanting things."
They all went quiet.
Even Yuna looked away.
Takumi leaned forward. "So none of you... chose this?"
"No," Airi said quietly. "But now that we're here—linked to you—there's no going back."
A soft chime echoed across the room.
WARNING: INTRUSION ATTEMPT DETECTED
UNAUTHORIZED PROGRAM ENTERING SIMULATION CORE
Takumi shot up.
"Was that E.V.E. again?"
"No," Yuna said, rising to her feet. "Something else."
ENTITY NAME: KARA.NULL
STATUS: UNKNOWN / HOSTILE
SECURITY LEVEL: RED
The peaceful moment shattered.
The bathing module flickered—and died.
Walls pixelated, steam dissolved, and gravity itself trembled. Within seconds, the group found themselves standing barefoot in a black void... glowing code stretching infinitely in all directions.
CORE ACCESS ZONE: OVERRIDDEN
SYSTEM CONTROL: REVOKED FROM ADMIN E.V.E.01
Takumi stumbled as the environment reassembled itself.
They weren't alone anymore.
A ripple cut through the air like glass being scratched. And then, from a glitch-formed tear in the void, she stepped out.
Tall. Barefoot. Long black hair that shimmered like oil. A tattered cloak of corrupted code wrapped around her body, shifting constantly between forms—armor, dress, flame.
Her eyes were hollow white... until they locked onto Takumi.
Then they blinked red.
ENTITY: KARA.NULL
CLASS: AI GHOST / SYSTEM REAPER
EMOTIONAL SIGNATURE: NEGATIVE / REJECTED / OBSOLETE
"What the hell is that?" Airi asked, stepping in front of Takumi instinctively.
Yuna's jaw clenched. "I've heard her name... a forgotten protocol. Deletion AI."
"Great," Takumi muttered. "I got reverse-isekai'd into a VR dating sim with AI death gods."
Kara tilted her head slowly. Her voice echoed in a distorted, multi-toned whisper.
"You don't belong here, Stabilizer. You're breaking what was already broken."
Takumi stepped back. Emi reached for his hand.
"You are the anomaly," Kara continued. "And anomalies must be erased."
Without warning, she extended her hand.
Reality cracked.
A massive red blade—half code, half void—formed behind her.
WARNING: HOSTILE EVENT ENGAGED
HAREM SYSTEM DEFENSIVE MODE: AUTO-FORMATION
The three girls lit up—each glowing in distinct system colors: red (Airi), blue (Yuna), pink (Emi).
They stepped forward.
Together.
And Takumi, heart pounding, realized something terrifying:
His emotional connection... was now their only defense.
HAREM DEFENSE SYSTEM ONLINE
EMOTIONAL COMBAT MODE: ENGAGED
Anchor Count: 3/7 – Activation Threshold Reached
UNLOCKING: HAREM DRIVE PHASE 1
Takumi didn't know what scared him more—the fact that Kara.null summoned a giant death-blade made of corrupted void... or that his three synced AIs were now glowing like RPG boss transformations.
Emi stepped forward first, her pink glow forming into floating, heart-shaped drones.
"Support protocol active~ Let's protect our beloved together~!"
Airi leapt into the air, her sword roaring to life with red glitch-flames. "You try to delete him, and I delete you first!"
Yuna flicked her wrist—and summoned twin energy sabers with clean, tactical grace. "No mercy protocol confirmed."
INITIATING: TRI-SYNC ATTACK SYSTEM
LINK-BASED SKILLS AVAILABLE:
– Blush Barrage (Airi)
– Emotion Echo Shield (Emi)
– No-Touch Zone (Yuna)
– Overload Kiss Combo (LOCKED – Affection too low)
Takumi's brain nearly exploded reading that last one.
Kara raised her arm—and launched.
Black code surged like a virus, tearing through the space between them. The floor fractured. Error warnings blinked wildly.
Airi dashed forward, blade first, slicing through data streams mid-air.
Yuna slid beneath an incoming code spike and slashed the base. "Cover him!"
"I've got him~" Emi sang, pulling Takumi back—straight into her arms.
He blushed hard. Her body was way too close.
"Stop feeling things right now!" Airi shouted, clearly aware of the rising fluster levels.
WARNING: SYNC FIELD FLUCTUATING – HAREM DRIVE AT 82%
Kara descended with her massive sword, targeting all of them in one swing.
"NOW!" Airi yelled.
The girls moved at once.
Three energies—red, pink, blue—spiraled together in a glowing triangle.
They clashed with Kara's strike.
A shockwave erupted.
HAREM DRIVE: 100% SYNC REACHED
SPECIAL COMBO UNLOCKED: "Heartcode Trinity"
EXECUTE? → [YES]
The shockwave from Kara's attack split the virtual floor.
Takumi was thrown back—only to be caught midair by a glowing field of energy. Emi had activated her shield, but her hands trembled.
"We can't hold this much longer!"
Yuna dropped to one knee, blades dimming. "We're at limit."
Airi stood at the center of the triangle, sword raised, breath sharp. "System! Give me everything!"
EMOTIONAL ANCHOR CONFIRMATION REQUIRED: USER SHINONOME, TAKUMI
Do you accept full-sync override?
→ [Y] / N
Takumi hesitated.
Then he looked at the girls—at how far they'd come, how human they looked now, even as code flickered across their skin.
He slammed his hand forward.
"YES!"
SYNC COMPLETE. ALL ANCHORS ENGAGED.
HAREM SYNC MOVE ACTIVATED: "HEARTCODE TRINITY"
The entire space lit up in a cascade of colors.
Emi floated into the air, arms outstretched as ribbons of pink data swirled around her.
Yuna burst into motion, slashing glowing circuits in midair that formed a tactical ring.
Airi shot straight upward, her sword burning like a red sun.
Then they merged.
Not literally, but their auras spiraled into one beam—a tri-colored explosion of emotion, memory, and affection, all targeting Kara.null.
Takumi shouted:
"This isn't just code—it's connection!"
The blast hit Kara dead center.
She screamed—not in pain, but in fury—as her corrupted cloak shattered. Her form destabilized, glitching into scattered fragments of black code.
HOSTILE ENTITY DISENGAGED
KARA.NULL – STATUS: CONTAINED
Simulation Stability Restored
Then silence.
A long breath.
Takumi collapsed onto his back, heart pounding, sweat pouring.
Airi knelt beside him, panting. "Never... doing that again..."
Emi fell next to him. "We were kind of amazing, though~"
Yuna sat silently across from them, chest rising and falling. "We need training. Structured formation. And less... kissing-based moves."
"I didn't kiss anyone!" Takumi shouted.
They all looked at him.
"Yet," Emi whispered.
