Kazuto Yamashiro was not supposed to die like this.
Twenty years old. A professional shut-in. A lifelong enjoyer of two-dimensional women with… impressive proportions. His parents gave up on him years ago. His friends? None. His lovers? Only digital ones with customizable bust sliders.
And his greatest dream?
To one day bury his face in a real, soft, warm, impossibly thicc ass.
…That dream died with him.
Literally.
Because on one lonely night, Kazuto slurped instant noodles while watching his favorite ecchi anime, and fate struck.
One badly timed slurp.
One slippery, rebellious noodle.
One blocked airway.
"Guhhh—cough—hrrrk—!"
He fell out of his chair, arms flailing, rolling onto the tatami mat. His last sight: the anime demon queen's boobs bouncing in glorious HD.
And then… darkness.
The Afterlife
When consciousness returned, Kazuto found himself floating in an endless starry void.
"What the…? Am I dead?"
His voice echoed strangely. No body. No weight. Just soul.
Then—he heard harp music. Divine, seductive, like angels playing R&B. A golden throne emerged from the void. And on that throne was a figure.
No. Not a figure.
A waifu.
Correction. A goddess.
Correction again: a goddess whose entire ass filled his vision.
Round. Glowing. So big it might have its own orbit. Each cheek radiated holy light, runes glowing across divine skin like constellations.
Kazuto's soul immediately nosebled, though he didn't even have a nose anymore.
"W-wha… haaa… this… this is heaven."
The goddess didn't turn. Instead, she bent slightly forward, and the jiggle that followed nearly broke his sanity.
"Mortal Kazuto Yamashiro," her voice rang like church bells mixed with moans, "you have died."
Kazuto nodded violently. "Y-yes, great thicc goddess, I have indeed died by noodle, but please, PLEASE let me stay right here for eternity!"
"No. You shall be reborn in another world."
Her tone was serious. But Kazuto's eyes were glued to her divine backside.
"Can I… c-can I be reborn there?" he whimpered, pointing at her glowing crack.
The goddess ignored him.
"In this new world, you shall not be a warrior. Not a mage. Not a hero. Instead, you are cursed with the role of… the [Lewd Hero]."
Kazuto blinked. "…That sounds like the greatest blessing in history."
"It is no blessing. It is eternal torment."
"Lady, I lived my whole life surrounded by flat-screen anime girls. If you're telling me I'm about to be surrounded by real waifus with asses like yours…" His eyes sparkled like a starving man at a buffet. "SIGN ME UP!"
"Your strength shall grow not by training, nor by slaying foes. It shall grow only through thiccness. Through the bounce of bosoms. Through the quake of asses. The more divine the jiggle, the more power you shall gain."
Kazuto fell to his knees in the void, tears streaming.
"Finally… a system that understands me."
"Then your fate is sealed."
The goddess raised her glowing hand. A system window appeared in the void:
[You have been granted the Cursed Class: Lewd Hero.]
[System Installed: Booty-Based Power Growth.]
[Warning: Side Effects may include nosebleeds, unwanted erections, and death by snu-snu.]
Kazuto clenched his fists.
"Yes. Yes! YESSS!!"
The goddess leaned forward slightly more, her divine ass eclipsing the last stars.
"Now… begone."
Before Kazuto could leap forward and hug her, the floor of the void collapsed. He fell screaming—straight toward her glowing booty crack.
And then—
The New World
SLAM!
Kazuto hit dirt face-first. His lungs filled with grass and dust.
"Ghh—ack—pfft—owwww…"
Before he could stand, a blade pressed against his throat.
"Pervert! Who are you?!"
Kazuto froze. His eyes traveled upward—past armored boots, past thick thighs squeezed by stockings, past hips that looked sculpted by gods—
And stopped at her face.
A girl. A waifu. A real, three-dimensional, flesh-and-blood anime waifu.
She had blazing crimson hair tied into a ponytail, golden eyes sharp like a predator, and skin glistening with sweat. Her chest strained against a breastplate clearly not designed to contain such massive assets. And below, her skirt barely concealed the roundest, fattest ass Kazuto had ever seen.
His mouth fell open. His nose immediately sprayed blood.
"…Oh my god," he whispered. "Gravity finally has competition."
The girl's face went red. "W-what are you staring at, idiot?!"
Kazuto trembled. "It's… it's real. The ass of destiny…!"
She pressed her sword harder. "Say that again and I'll cut you down where you stand!"
But fate intervened.
Three goblins leapt out from the bushes, snarling.
The girl spun, sword flashing. Kazuto expected steel. But what truly struck was her hip rotation.
Her booty swung in perfect sync with her slash.
And unleashed a shockwave.
The air rippled. The goblins were blasted off their feet, thrown into trees like ragdolls.
Kazuto's system pinged:
[System Activated: Lewd Hero.]
[Detected: Tsundere Bootyquake Slash.]
[Power Level +50.]
Kazuto's jaw dropped.
"T-that was a bootyquake! A literal attack powered by ASS!!"
The girl blinked in confusion, then turned, cheeks flushed. "Wh-what nonsense are you spouting?!"
Kazuto leapt up, eyes shining with holy purpose.
"I knew it… my system isn't a curse… it's a blessing from the Booty Goddess herself! And you—" He pointed dramatically at her jiggling hips. "—are my destined partner!"
She twitched. "…Excuse me?"
[Quest Unlocked: Acquire Party Member (Tsundere Booty Edition).]
[Reward: 100 Lewd Points.]
Kazuto pumped his fist.
"Yes! Waifu quest accepted!"
The girl raised her sword again. "Waifu—?! Stop talking like a creep or I swear—"
Another goblin wave burst from the grass.
"Move!" she barked. She dashed forward, armor clanking, booty bouncing with terrifying force.
Kazuto followed like a puppy, screaming at the top of his lungs:
"LEWD HERO, ACTIVATEEEE!!!"
