Aika Kiryuu had always been the punchline for Issei Hyoudou and his pervy trio—Motohama and Matsuda. To them, she wasn’t a woman, just a quirky sidekick with her lewd comments and glasses. They’d laugh off her flirtations, dismiss her presence, and treat her like a gag character. At first, Aika brushed it off, smirking to herself and plotting petty revenge in her mind. But over time, the constant dismissal gnawed at her, festering into a dark, simmering rage. She wasn’t just going to ignore it anymore—she was going to make them regret it.
 
One day at Kuoh Academy, Aika trailed behind the Occult Research Club—Rias Gremory, Akeno Himejima, Asia Argento, Xenovia Quarta, and Irina Shidou—and the Student Council—Sona Sitri and Tsubaki Shinra—as they strutted into the cafeteria. Their voluptuous figures were impossible to ignore: Rias’s crimson hair swaying over her ample chest, Akeno’s teasing smile paired with her jiggling breasts, Tsubaki’s stern elegance accentuating her curves, and Sona’s cool authority barely hiding her own assets. Aika’s eyes lingered, her usual playful thoughts twisting into something hungrier. They look like a snack, she mused, licking her lips. No… a whole buffet.
 
The idea hit her like a lightning bolt. Lunchtime was the perfect excuse. Why not indulge? She rummaged through her bag, pulling out a small device she’d secretly crafted—a nerve bomb, a paralyzing gadget she’d tinkered with in her spare time. Its effects would last thirty minutes, leaving her prey helpless. A wicked grin spread across her face as she muttered, “Time to eat.”
 
She detonated the nerve bomb in the cafeteria’s center. BZZT! A faint pulse rippled outward, and within seconds, the ORC and SC girls crumpled to the floor, limbs twitching but immobilized. Students screamed and fled, leaving Aika alone with her banquet. She adjusted her glasses, her smug grin widening as she approached Sona Sitri first. “Student Council prez, huh? So composed… let’s see how you taste,” Aika taunted, grabbing Sona by the shoulders. She stretched her jaw impossibly wide—a trick she’d unlocked through some twisted magic she’d stumbled upon—and shoved Sona’s head into her maw. SLURP! The girl’s glasses clattered to the floor as Aika gulped, savoring the squirming protests muffled against her throat. Sona’s slender frame slid down easily, her struggles only fueling Aika’s hunger. GLURK! With a wet swallow, Sona vanished into her stomach, bulging it outward.
 
Next were Irina and Xenovia, sprawled side by side. “Holy girls for a sinful meal,” Aika chuckled, dragging Irina’s limp form up by her twintails. GULP! She swallowed the angel whole, burping loudly—BRRRAP!—as Irina’s cross necklace flew out, dangling from her lips. “Oops, guess you’re not praying your way out of this.” Xenovia followed, her muscular build a tougher swallow, but Aika relished the challenge, moaning as the swordswoman’s kicking legs disappeared down her gullet. SHLORP! Her belly swelled grotesquely, wriggling with the three girls’ faint struggles. GROOOOAN! Aika patted it, letting out a satisfied belch—URRRRP! “You’re all so filling… but I’ve got room for more.”
 
Rias Gremory stirred awake just as Aika loomed over Akeno Himejima. The redhead’s eyes widened in disbelief as Aika orally engulfed Akeno, her sadistic giggles mixing with the wet slurps. SLUUURP! Akeno’s voluptuous chest squished against Aika’s lips before vanishing, her muffled cries fading into gurgles. Simultaneously, Aika grabbed Tsubaki Shinra, smirking as she shoved the vice-president’s head toward her rear. SHHHHLORP! With a grotesque sound, Tsubaki was sucked in anally, her long legs flailing before being fully consumed. “Stop this, Aika!” Rias shouted, her voice trembling with rage and helplessness. She tried to crawl away, but her body was still sluggish from the nerve bomb. Aika turned, her overstuffed belly swaying—BLORP!—and sauntered toward Rias. She pulled out her phone, snapping photos of the crimson-haired heiress. “Say cheese, prez. These’ll lure in some rescuers… or more meals.”
 
“If you warn anyone,” Aika sneered, “I’ll pin it all on Issei. Imagine his face when everyone thinks he gobbled you up. So, how about you girls entertain me while I dispose of you? Play nice, and I might not eat anyone else… maybe.” Rias glared, powerless as Aika’s shadow loomed closer.
 
Asia Argento regained consciousness just in time to see Aika’s massive, writhing gut. GRRRGLE! “W-what’s happening?!” she gasped, clutching her cross. Before she could scream, Aika spun a lie. “Oh, Asia, sweet little Asia. If you climb in willingly, it’ll overload me. I’ll puke them all up—promise!” Desperate to save her friends, Asia nodded tearfully. “Okay… I’ll do it.” She stepped forward, trembling as Aika’s jaws stretched wide again. GULP! The blonde slipped inside, her petite form barely a challenge. But instead of vomiting, Aika’s belly only gurgled louder—BLUUURGLE!—stretching to accommodate its final occupant. “Oops, guess I lied,” Aika taunted, patting her squirming stomach. “Plenty of room for you, healer.”
 
Inside, the girls begged and pleaded, their voices overlapping in a cacophony of despair. Aika burped again—BRAAAAAP!—Xenovia’s hairpin tumbling out with a clatter. “Melt down nicely for me, okay? I could use some curves,” she teased, swaying her hips as digestion kicked in. Her gut churned and groaned—GRRRRRN! CHURN!—the outlines of her prey softening as acids worked them into mush. Hours later, Aika strutted back into the school, her body transformed. Her chest ballooned outward, straining her uniform, while her hips and ass widened into a perfect hourglass. The girls had padded her out beautifully—Rias’s fiery essence in her bust, Akeno’s allure in her rear, Sona’s elegance in her thighs. She admired herself in a hallway mirror, smirking. “Not bad, ladies. You’re better as me than you ever were as you.”
 
A loud GUUUURGLE! interrupted her preening. “Oh, time to let you out,” she giggled, heading to the restroom. Locking the door, she squatted over the toilet, grunting as she began the disposal. PLOP! SPLAT! First came Sona’s cracked glasses, plopping into the bowl amidst a thick, steaming pile. A fart ripped through the air—FRRRRT!—reeking of digested holiness as Irina’s cross clinked out next, tangled in the mess. THUD! SPLORCH! Xenovia’s sword sheath fragments followed, then Akeno’s hair ribbon, all buried in the grotesque sludge. Rias’s crimson locks were the last identifiable remnant, swirling down with a flush—FLUUUUSH! Aika stood, adjusting her skirt over her newly fattened ass. “Thanks for the upgrade, girls,” she said, letting out a final burp—URRRRP!—that carried Asia’s faint floral scent.
 
Aika found Issei, Motohama, and Matsuda in the courtyard, oblivious to the chaos. She sauntered up, her exaggerated curves bouncing with each step. “Hey, boys,” she purred, leaning forward to flaunt her chest. “Still think I’m a joke?” Issei gaped, stammering, “W-where’d you get those?!” Aika smirked, letting out a loud belch—BRRRRAP!—that sent Rias’s hairclip skittering across the ground. “Oh, just a little lunch. You should’ve seen your precious harem wiggle down my throat. Too bad you’ll never find them now—unless you check the sewers.” The trio paled as she turned, swaying her hips tauntingly. “Next time you laugh at me,” she called over her shoulder, “remember who’s the real predator here.” With a cruel laugh and a parting fart—PFFFFT!—that stank of digested devil, Aika strutted off, leaving the pervy trio speechless—and terrified.
