That Day When Suzuki-kun Wasn't the Mob-B! Chapter 289: A Shimaidon on the Line

"What exactly is this place?" Serafall asked, her large, golden eyes blinking in genuine awe.

Just moments ago, they had been standing in the dimly lit, wooden basement of Finn's newly renovated Kuoh Shrine. But the moment they stepped through the reinforced door, the cramped walls vanished, replaced by an impossibly vast, open expanse.

"It's an artificial pocket dimension, similar to the ones utilized in official Rating Games. Only this one is fundamentally much stronger," Finn explained calmly.

With a casual flick of his wrist, Finn accessed the dimensional controls. Instantly, the blank, white void rippled. The sharp, fresh scent of pine trees and salty ocean air suddenly flooded the space. Lush, towering mountain ranges erupted from the ground, and a sprawling, crystal-clear ocean materialized in the distance.

"........."

The group watching from the observation deck behind the barrier fell into absolute, stunned silence. The sheer, overwhelming scale of the environment was breathtaking. The only ones who didn't look completely utterly dumbfounded were Akeno, Asia, and Xenovia. Given Xenovia's notoriously destructive and loud training habits, Finn regularly brought his women down here to practice so they wouldn't accidentally level his home.

"Good, let's do this! Gu!"

Serafall leaped into the artificial valley with a surprisingly heavy, athletic thud. The sudden movement caused the frilly, bright pink skirt of her magical girl outfit to flutter wildly, exposing the absolute territory of her smooth, thick thighs. She tapped the tip of her star-topped staff against the grassy ground, clenching both of her small fists. She looked up at Finn with an expression that was undeniably adorable, yet burned with the unmistakable, bloodthirsty intent of a seasoned warrior.

Finn just stared at the bouncing, heavily endowed cosplayer, entirely speechless.

"Are you absolutely sure you want to fight me, Serafall-sama?" Finn asked.

"Call me the dazzling Magical Girl, Levia-Tan! If you don't, then I will only refer to you as the evil villain, Balam!" she demanded, pointing her staff at him accusingly.

"........"

Finn glanced up toward the observation deck, hoping to catch Sona's eye for a lifeline. Sona simply pinched the bridge of her nose, her face flushed red with secondhand embarrassment, and shook her head. He was on his own.

"Okay, Levia-Tan," Finn sighed.

Honestly, he didn't mind being called 'Balam'. It sounded fittingly like a villainous baron from a Sunday morning magical girl anime. Still, he wondered if things were truly this simple. Serafall appeared to be a bubbly, silly ball of pure excitement, but Finn's instincts told him it was all a carefully constructed disguise—a brilliant, disarming facade designed to make her enemies completely drop their guard before she slaughtered them.

"Muuuuuuuu!!!!"

Serafall puffed out her soft cheeks, glaring at him intensely. Her massive chest heaved with each dramatic breath, stretching the thin pink fabric of her top to its absolute limit.

"......."

Is she actually serious? Finn thought.

"Are you genuinely serious about fighting me, Levia-Tan?"

"Of course!" Serafall's face instantly brightened, immensely pleased that he had humored her nickname. "This Great Magical Girl Levia-Tan has decided to vanquish you! So don't you dare try to run away, Balam-kun!"

"......."

Finn truly felt it would be better for everyone if they just walked away, but a darker, more ambitious part of his mind wanted to test his current limits—especially after integrating the King Piece.

If he had to be brutally honest with himself, he was confident he could crush her.

It might have sounded arrogant to dismiss a reigning Maou, but considering his arsenal—the absolute invisibility that rendered him untraceable, his raw, Herculean physical strength, and a sword capable of severing the divine itself—he didn't see Serafall as an insurmountable wall.

Based on his knowledge, Serafall's true domain was absolute ice manipulation, an advanced, mutated derivation of the Sitri House's innate water manipulation.

Water was deceptively simple, but in massive quantities, it could summon world-ending tsunamis. Ice, however, was far more sinister. It was a stagnant, deadly element. While fire burned everything to ash and vanished, ice was static, preserving its victims in a frozen, agonizing eternity.

But even against such a terrifying element, Finn couldn't picture his own defeat. Combat in the supernatural world often operated on a rock-paper-scissors logic, where elements countered each other. Finn, however, possessed no such weaknesses. Thanks to the Self-Made ability he had assimilated from 'Suzuki' of Tensura, his body possessed terrifying adaptability.

Just as he had violently adapted to and gained complete immunity against the Great King Zekram Bael's absolute Power of Destruction, Finn knew that the moment his body processed the biting cold of Serafall's ice, the battle would effectively be over.

"Are you afraid, Balam-chan?" Serafall teased, flashing a silly, confident grin.

"I'm not," Finn shook his head lazily. "But I have to wonder... if you lose down here in front of your precious little sister and everyone else, won't your entire prestige be utterly shattered?"

"........"

A heavy, deathly silence fell over the observation deck.

"You won't be seen as the strong, invincible Onee-sama ever again," Finn added smoothly, delivering the psychological strike.

He was openly mocking her.

This was likely the very first time in Serafall Leviathan's long life that anyone had dared to mock her to her face. Usually, people simply smiled awkwardly and accepted her bizarre, highly revealing outfits and childish antics because she possessed the overwhelming power to force her eccentricities into the realm of 'common sense'. The weak had no choice but to conform to the norms dictated by the strong.

But Finn wasn't weak.

"I really like you, Finn-chan."

"Don't call me Finn-chan. Stick to Balam," Finn replied dryly.

"Oh! How incredibly cute! Have you finally decided to show your true, wicked side~?" Serafall smiled. The bubbly, silly demeanor vanished, replaced by a suffocating, intoxicatingly dangerous aura. She knew his polite, lazy attitude was just an act. He was a predator who played the fool until his prey was perfectly in the crosshairs.

"Don't make it sound like I'm the villain here," Finn sighed, rolling his shoulders. "Who has constantly caused all the trouble in my life? If you hadn't provoked me, would I have even bothered to fight you?"

"But, don't you want to?" Serafall's voice suddenly dropped an octave, dripping with thick, unapologetic lust. She took a step closer, tracing a finger down the curve of her own jaw. "Don't you want a Shimaidon of the two Sitri sisters? I am still a pure virgin, too, you know? If you win, you can fully claim me. You can put your cock deep inside me, pour all of your hot semen into my womb, and completely impregnate me~!"

"........"

Finn froze, utterly blindsided by the sheer, unfiltered obscenity spewing from the mouth of a woman with such a youthful, angelic face.

"So, you better stay alive, okay?"

Before Finn could even process the lewd wager, Serafall moved.

"Ice."

Her demonic energy exploded. A wave of intense, unimaginable horror washed over everyone in the dimension. In a fraction of a second, the temperature plummeted past absolute zero. The lush, green mountains and the roaring ocean were instantly swallowed by a blinding, jagged wave of frost.

Up on the observation deck, Sona, Rias, and the others stumbled back. Even though the artificial barrier protected them from the physical attack, the sheer, bone-chilling temperature radiating through the glass made their breath visible in the air.

Down in the valley, Finn was completely entombed inside a colossal, towering mountain of solid, blue glacial ice.

"Finn-sama!" Ravel screamed, pressing her hands against the freezing glass in absolute terror.

Serafall hadn't held back. Knowing Finn's infamous reputation for opening battles with devastating, world-ending strikes, she had decided to strike first. While it wasn't her absolute maximum output, the glacier she had just summoned was easily dense enough to wipe the entire island of Japan off the map.

But Serafall Leviathan wasn't the only one capable of destroying a country.

Crack.

CRACK. CRACK. CRACK!

A deafening, explosive sound echoed through the frozen wasteland. Massive, spider-web fissures erupted across the surface of the glacial mountain. With a thunderous boom, the ice shattered into a million glittering, razor-sharp shards, violently pushed aside by sheer, monstrous physical force.

Finn emerged from the epicenter of the blast. He casually rolled his shoulders and cracked his neck, brushing a chunk of ice off his shirt.

"Damn, that is actually pretty cold," Finn muttered, his body steaming as his blood rapidly adapted, generating an intense, localized heat to counter the frost.

Watching him step out of her apocalyptic attack entirely unharmed, the dangerous, lustful smile on Serafall's face only grew wider. Her breathing hitched, and she slowly, deliberately dragged her wet tongue across her plump bottom lip.
