"Some people say the universe has a plan. If that's true, then the universe must've been drunk the day she fell into my life."
I hadn't left my room in 42 days.
The window was shut tight, the curtains were drawn, and the only source of light came from the flickering glare of my 40-inch monitor, soaked in energy drink cans and half-eaten instant curry bowls. To most people, I was a failure. A waste of space. A NEET, living off my parents' old savings, long after they'd left this world behind.
But in reality?
I was a well-trained, bored as hell, combat-obsessedex-martial arts prodigy who'd lost his drive to fight humans.
I did 500 push-ups before breakfast. Shadowboxed with the air conditioning unit. Read ancient tomes of strategy between sessions of late-night dungeon RPGs. But motivation? Zero. Nada. Not a single damn reason to go outside and show the world what I was made of.
Until she happened.
The ceiling exploded at 2:42 a.m.
I blinked, confused. Dust filled my room. Cracks split the walls like spider veins. My LED lights shorted out with a pop. A strange smell—like starlight and cold perfume—hit my nose.
And then, from the gaping hole above, she crashed down onto my bed like a comet made of silk and thighs.
"Ughh... Where the hell...?"
A woman. A literal celestial woman. Pale skin that glowed faintly in the dark. Long, silver hair with streaks of violet that shimmered like galaxies. Armor that looked handcrafted by angels. Her chest rose and fell with heavy, graceful breaths.
Her legs… were draped over my pillow.
And my face.
"Okay. Not a dream."
"GET. OFF. ALREADY"
I shoved her sideways. She groaned and rolled to the edge of the bed, coughing stardust like it was just another Thursday.
Her eyes snapped open. Violet. Ancient. Ethereal.
She sat up, looked around, then locked eyes with me.
"...You're not supposed to see me yet!"
I blinked. "Lady, you just turned my ceiling into a drive-thru."
She stared at me, her expression somewhere between confusion and horror.
"…I think I took the wrong descent vector. This isn't the Sacred Hero's palace."
"Try again in two years. He's probably still in high school."
She narrowed her eyes at me. "Who are you?"
"Kaito Ren. Professional shut-in. Amateur survivalist. Former jiu-jitsu state champion. Current… unemployed legend."
I scratched my head, brushing plaster dust off my bare chest. My abs, thankfully, were still intact despite the goddamn roof collapse.
She frowned. "You… look like a mortal. But your body is—trained? That's rare for your kind."
"I got bored."
Silence.
She stood up, brushing imaginary dirt off her armor. "Very well. I cannot return to the celestial realm until I form a pact. Protocol demands I choose someone from the world I entered."
I squinted. "That's convenient."
She crossed her arms. "You're my only option."
"What exactly does a pact involve?"
She took a step forward. The air grew heavy—like gravity itself bent around her.
Her finger tapped my chest.
A glowing sigil burned into my skin.
I screamed like someone who'd bitten into molten curry.
Flashes of otherworldly visions assaulted my brain—wars in heaven, devils clawing up through the earth, swords made of pure will, voices chanting in a language that felt older than time.
And then—it stopped.
My body surged. I could feel it. Something inside me… broke. And rebuilt itself.
"W-What the hell did you just do?!"
"I marked you with the Slave Pact of Divinity," she said flatly. "Your soul is now bound to mine. In exchange, you will receive strength beyond the comprehension of your world."
Slave pact? Did she just make me her dog?!
"Time out! What kind of goddess just enslaves random dudes because she missed her exit?!"
She tilted her head, amused. "You weren't doing anything important."
"That's not the point!"
Then a pulse hit my chest again.
A small flicker—my body reacting to danger. From outside.
I turned to the broken ceiling.
Figures—dark, winged, and growling—descended from the sky, slipping through the rift like shadowy insects.
The goddess's expression hardened. "Devils. They must've tracked my descent. They're here to kill me before the contract solidifies."
I cracked my knuckles.
"Cool. Been a while since I kicked something that wasn't a vending machine."
She raised an eyebrow. "You'll die."
I smirked.
"Lady, I've been dead on the inside for three years."
"Let's see what this pact can do."
The first devil landed. I moved.
My fist cracked its jaw clean off.
The next came swinging a blade—too slow. I disarmed him, flipped him, and drove my knee into his spine.
The last one tried to fly away.
A flick of my hand, and something—an ethereal chain—lashed out from my palm and pulled him back into the earth like a harpoon from hell.
Silence.
I stood in my half-destroyed room, blood on my arms, heart thundering with power I hadn't trained for—but now owned.
The goddess blinked. "…You… just killed three fiends in under ten seconds."
"Yeah. Not bad for a loser, right?"
Her expression softened, just for a moment.
Then she smirked.
"I suppose you'll do. From now on, you are mine."
I stepped closer.
"And you're gonna have to work real hard to keep me in chains."
She stared at me.
"…You're enjoying this far too much."
I grinned. "I'm a NEET. This is the most exciting thing that's happened since high-speed internet."
"And that's how it all started. The pact. The war. The blood and glory. The ride of a lifetime.Her descent might've been a mistake... but choosing me? That was fate."
