The ceiling light in Haruto's cramped Shinjuku apartment had been flickering for weeks. He never fixed it. Too tired after twelve-hour shifts at the data-entry job that paid just enough to keep the Wi-Fi on and the fridge stocked with cup ramen and cheap beer. Tonight was no different.
He lay on the futon, phone propped against a pillow, earbuds in, volume low enough that the neighbors wouldn't complain again. The video had loaded three minutes ago — a soft-voiced AV actress in a school uniform whispering things no real high-school girl would ever say. Haruto's hand moved mechanically, familiar rhythm, chasing the usual release.
Then the pressure started.
Not the good kind.
A vise clamped around his chest. Breath shortened. Vision tunneled. He tried to sit up; the phone clattered to the floor. The actress's moans kept looping through the earbuds like a broken record.
Shit—shit—
Heart stuttered once, twice.
Black.
When awareness returned, it came wrapped in heat and sound: water drumming on tile, steam curling against skin.
He opened his eyes.
Or rather… she did.
Long strands of wet black hair clung to shoulders that were narrower than they should have been. Slim arms lifted on instinct. Hands smaller, fingers finer, nails short but neatly shaped, painted a faint rose. Water sluiced down over curves that definitely hadn't been there five seconds ago.
Breasts. Full, soft, heavy enough to shift with every shallow breath. Dark nipples tightened under the spray.
A startled sound escaped — high, melodic, unmistakably feminine.
The showerhead was still running. Hot water now, thank god. She reached to turn it off, missed, fumbled, finally twisted the knob. Silence fell except for dripping and her own ragged breathing.
Legs trembled as she stepped out onto the bath mat. The tiny bathroom mirror was completely fogged. She wiped it with the heel of her palm.
The face staring back was heartbreakingly pretty.
Large, slightly upturned eyes the color of dark honey. Straight nose, full lips parted in shock, cheeks flushed from heat. Long lashes clumped with water droplets. Hair hung in glossy sheets past the collarbone, framing a swan-like neck.
Aoi Takahashi.
The name floated up unbidden, attached to memories that weren't hers but felt like they were: second-year literature major at Waseda satellite campus, part-time barista at a small Shimokitazawa café called "Moonlit Beans," rent due on the fifteenth, favorite convenience store onigiri was salmon mayo, ex-boyfriend Kenji had dumped her three months ago because she "wasn't exciting enough in bed."
She touched her cheek. The reflection mirrored it perfectly.
"This… isn't happening."
Voice soft, lilting, Tokyo accent with just a trace of Chiba softness from childhood. Nothing like Haruto's flat, tired baritone.
She looked down.
Flat stomach. Gentle flare of hips. Thighs that touched slightly when she shifted weight. And between them — nothing familiar. Soft folds, sensitive even to the cooling air.
A hysterical laugh bubbled up and died in her throat.
Then the blue window appeared.
Not on the mirror. Inside her vision, floating like augmented reality, crisp white text on semi-transparent blue.

Accept? [Y/N][Tutorial: Would you like a brief explanation of core mechanics?]
She stared at the floating text. Blinked hard. It didn't disappear.
ROB, you absolute piece of shit.
The memory of that cheerful, mocking voice echoed back.
"You were kinda basic, but entertaining. Let's see how you handle being the prize instead."
She pressed mental lips together.
Y.
The tutorial expanded into a neat list.
LME Overview
Earn LP through any act that generates lust (observed arousal in others, personal pleasure, sexual contact). Accumulate MP via major milestones (firsts, taboos broken, large-scale events). Reach MP threshold → unlock world migration. Current body will terminate during/after peak event. Retained perks carry across worlds at reduced potency. New body selected for maximum LP potential. No forced tasks after tutorial. Optional quests provide bonus LP/MP. Death in current world = automatic jump (no second chances).
Current Goal: Survive and thrive until migration threshold.
She exhaled slowly.
So it's a game. A very fucked-up game.
The quest timer appeared in the corner: 00:00 / 05:00
She looked back at the mirror. Those big eyes stared back, pupils already dilated from adrenaline and… curiosity?
If I'm stuck like this, might as well test the hardware.
She reached up. Cupped one breast.
The sensation hit like a live wire.
Soft weight in her palm. Nipple pebbled instantly under the pad of her thumb. A low, involuntary sound slipped out — half gasp, half moan.
Holy—
She circled slowly. Pleasure radiated outward in warm pulses, nothing like the focused, linear build she was used to. It spread. Down her ribs, across her stomach, pooling hot and liquid between her thighs.
Other hand drifted lower. Hesitated at the soft triangle of trimmed hair. Then lower still.
First contact with slick folds: sharp inhale.
She was already wet. Not dripping, but unmistakably ready. The sensitivity bonus made every ridge of her fingerprint feel exaggerated. She parted herself gently, middle finger sliding along the seam, brushing the swollen bud at the top.
Knees nearly buckled.
Fuck. This is dangerous.
She braced one forearm on the sink. Leaned closer to the mirror. Forced eye contact.
Timer: 01:23
She stroked again. Slower this time. Exploring. Up and down, then small circles around the clit. Each pass sent sparks up her spine. Breaths came shorter. The reflection's cheeks flushed deeper pink. Lips parted. Pupils blown wide.
At three minutes the rhythm changed without conscious decision. Hips rocked forward to meet her hand. Breasts swayed gently with the motion. She pinched one nipple lightly — the dual stimulation made her moan openly, sound echoing off the tiles.
This isn't fair. How do girls concentrate on anything?
Four minutes. Pressure built differently — not a race to the finish line, but a slow, inexorable tide rising. Core tightened. Thighs trembled. She added a second finger, sliding shallowly inside while thumb kept working the clit.
The mirror fogged again from her panting.
She wiped it frantically with her free wrist.
Eyes locked.
Timer: 04:48
She bit her lower lip. Hard.
At 05:00 exactly —
Everything clenched.
A broken cry tore from her throat. Back arched. Knees gave out completely. She slid down the wall, legs splayed, hand still pressed between thighs as aftershocks rolled through her in long, luxurious waves. Toes curled against the wet tile. Vision whited for a second.
When it cleared, she was slumped against the cool wall, chest heaving, skin flushed from throat to navel.
The blue box chimed — soft, almost polite.

She sat there for a long minute, water still dripping from the showerhead.
Then she laughed — soft, breathless, a little manic.
Okay. Okay, you win this round, ROB.
She pushed herself up on shaky legs. Turned off the water properly this time.
Towel around her body — soft, oversized, smelling faintly of lavender detergent. She padded into the main 1K room.
Small. Neat. Typical student life.
Low table with scattered textbooks and highlighters. Futon still folded against the wall. Tiny kitchenette with a single induction burner. One window overlooking a narrow alley and the side of the next building. Clothes rack instead of a closet: skirts, blouses, cardigans, a couple of casual dresses, one yukata for summer festivals.
Phone on the table — rose-gold case, cracked screen protector.
She picked it up. Unlocked with face ID (it worked instantly).

She opened the camera. Selfie mode.
The girl in the screen looked back — flushed cheeks, damp hair, eyes bright with something dangerous.
This is me now.
She set the phone down. Dropped the towel.
Naked in the middle of her own apartment, she stretched — arms overhead, back arched, feeling every new curve shift.
Pleasure echoes still hummed under her skin.
Let's see what fifty points buys.
She opened the system menu mentally.

She hesitated.
Then tapped Allure Aura Intensity +10 %.
LP: 30
A faint warmth spread through her chest, like static electricity settling.
Small start. Good enough.
She dressed slowly. Deliberately.
White cotton panties (simple, but the lace trim felt decadent against sensitive skin). Matching bra — push-up style she didn't remember buying but apparently Aoi owned. Pale-blue blouse, slightly sheer in direct light. Navy pleated skirt — mid-thigh, not scandalous but short enough to show thigh when sitting. Black cardigan. Knee-high socks. Loafers.
Hair: towel-dried, brushed, left loose to air-dry into soft waves.
She checked the mirror one last time.
The girl looking back was effortlessly pretty — the kind of beauty that made people do double-takes without realizing why.
She smiled.
Small. Secret. A little wicked.
Time to test the theory.
She grabbed her tote bag (textbooks, wallet, train pass, lip balm), slung it over one shoulder, and opened the door.
The hallway smelled of miso soup from the neighbor's kitchen and faint laundry detergent.
She stepped out.
Locked the door.
Took three steps toward the elevator.
Old man Tanaka from 302 shuffled past with his garbage bag. He glanced up — froze for half a second longer than usual. Eyes flicked down, then up again. Cheeks pinkened.
"G-good morning, Takahashi-san."
"Morning, Tanaka-san." She smiled sweetly. Voice like honey.
He nearly dropped the bag.
She kept walking.
Elevator dinged.
Inside: university student couple (probably Waseda too) already there. Boy looked up from his phone. Eyes widened slightly. Girl noticed, elbowed him.
Aoi pretended not to see.
But the system chimed quietly.
[Passive Allure Aura (Lv.1) – Active]Observed Reactions: +2 (prolonged gaze)LP +4 (passive gain)
Doors opened to the lobby.
She stepped into morning Tokyo air — crisp, carrying the smell of coffee from the konbini across the street and exhaust from the early buses.
People passed on the sidewalk.
A salaryman in a suit slowed his pace.
Two high-school girls in sailor uniforms giggled, then glanced back.
A delivery rider on a bike almost wobbled.
She felt each look like a tiny electric brush against her skin.
This… is addictive.
She turned toward Nakano Station.
First day as Aoi Takahashi.
First day of the rest of forever.
And the game had only just begun.
