This F-Rank Bubble Mage Is Too OP!

Kayl and his team clashed with the Alpha Rotling, their Skills flashing through the air, lighting up the dying forest in bursts of blue and red.

Blades slashed and guns fired, spells cracked the ground, but the creature refused to stay down.

Each time a limb was severed, it writhed and regrew—thicker, meaner, and faster than before. Blood hissed as it hit the ground, then congealed and returned to the Rotling's flesh like liquid muscle memory.

"Cut off the arm!" one of the Hunters shouted.

"No! Aim for the core!"

But none of it worked.

This was no ordinary dungeon spawn. The Alpha Rotling had evolved—just like a mini-boss, or worse, an actual boss. Its regenerative abilities were outrageous, almost as if it had adapted to counter their every move.

As if it had been programmed to endure the exact damage output of whoever attacked it.

Unless…

Unless someone had a Skill that could overwhelm that regeneration entirely.

Unfortunately for the Limo Group, only one among them had the kind of firepower needed to pull that off—and that was Kayl.

The group's leader stood firm, twin gatling guns spinning at his sides like turbines. His bald head flared with the backdraft of his barrage, his face soaked with sweat and grime. But he didn't stop firing.

Every bullet that found its mark released a surge of energy—Resonance—white and blue pulses that flowed from the Rotling's flesh back into Kayl's core. That energy gathered like storm clouds in his chest, then funneled into the barrels of his weapons.

The gatling guns grew brighter with each second, glowing with layered rings of condensed mana.

Kayl's jaw clenched. His eyes narrowed, veins bulging in his arms as he struggled to maintain control. The Resonance Skill was powerful, but draining. Every shot consumed a fraction of his MP, and he was burning through it fast.

"Damn… hold it together," he muttered, his voice low but intense. "Just a little more…"

Behind him, his teammates fought with everything they had. Their weapons flared, blades clashing against the Rotling's thick hide. Even though they were only E-Rank Hunters, their coordination and desperation pushed their firepower close to that of upper D-Rank fighters.

A blade of flame carved into the monster's thigh. Another Hunter slammed an icy spear into its side, pinning it momentarily to a dying tree.

But the monster just roared, tore itself free, and reformed.

Its regeneration was maddening.

Every wound closed within seconds, fresh flesh spiraling into place. It was like attacking water with a sword—visible impact, no lasting damage.

Kayl's fingers hovered over his triggers, his eyes focused on the glow building in the guns. Resonance energy had reached critical mass.

"Just a few more seconds!" he shouted. "Keep hitting it! I need a clean shot!"

Understanding his intent, the others redoubled their efforts. Their Skills flared brighter, more desperate. Each attack wasn't about damage now—it was about stalling. Creating an opening.

Kayl's chest glowed like a lantern.

Soon, the beam would be ready.

And when it was… the Alpha Rotling would face a shot no regeneration could ever heal.

A few seconds. That was all they needed.

The rotling horde had long been reduced to charred remains by the relentless bombardment of fire from the team's Mage. Each time a new batch erupted from the Alpha Rotling's bloated body, it was met with immediate, merciless incineration. Their caster moved with ruthless efficiency, turning the grotesque spawn into nothing but ash.

Experience points climbed steadily—meager, but still better than nothing. However, no one among the Limo Group was smiling. These weren't moments of triumph. They were fighting tooth and nail to stay alive against a monster that had no business spawning right at the get go.

The Alpha Rotling was a mutation—no, worse. A freak of nature.

They couldn't retreat now. Not after how far they'd come. Not when they were this close to victory. If they let this thing escape, it might get taken out by another team.

Besides… the loot.

Kayl's teeth clenched in both tension and anticipation, his breath ragged as his weapons glowed brighter with each bullet fired. His thoughts weren't just on surviving. They were already a step ahead, calculating risk and reward.

Bone Marrow Potion? Rotling Tooth? Death Flesh? His mind flashed through the possibilities.

If they were lucky, the Alpha might even drop a "Cursed Rot Core"—a rare material with absurdly high enhancement value, capable of strengthening gear or permanently increasing stats when refined. It was rare, but not impossible. If the dungeon gods smiled on them today, he might be the one to receive it.

More than that, there was always the chance of natural evolution. He'd heard rumors—hunters who defeated mutated bosses sometimes found their abilities awakening in new ways, not through leveling or skill books, but through sheer exposure to the powerful remains of such monsters. It was the type of power you earned.

He wanted it.

No—he needed it.

Just as the anticipation peaked in his chest, a scream pierced the tension.

One of their frontliners was flung backward like a ragdoll, smashing against a dying tree with a sickening crunch. His armor cracked, and blood splattered across the dark roots. The forest groaned in response, branches twitching like dying nerves.

The Alpha Rotling howled, a sickening, multi-toned roar that reverberated through the misty air. From its bulging, split-open back, undead limbs pushed out. Rotling zombies tumbled onto the battlefield in a grotesque wave of twitching limbs and gnashing teeth.

The sudden shift in pressure caught the Mage and the other melee Hunter off guard. In a blink, the zombies infiltrated their formation, breaking their defensive line and leaving a gaping path directly toward the backline—toward Kayl.

The monster saw it too.

With an enraged bellow, the three-meter tall Alpha surged forward. Its massive legs tore through the dirt, each step shaking the earth beneath them. Its claws gleamed wetly in the dim forest light, curved like scythes.

"Boss! WATCH OUT!" one of the group members screamed.

But Kayl didn't panic. His instincts kicked in. The moment his eyes locked onto the charging monster, a smirk stretched across his face. He had been waiting for this.

"Just right on time…" he muttered under his breath.

His chest pulsed with luminous energy—white and blue crackling through his body before rushing into both of his arm-mounted Gatling Guns. The metallic barrels spun with rising intensity, glowing brighter than ever. The humming deepened, a high-pitched whine like a reactor charging up. Sparks danced off the weapon's surface.

"Gotcha."

Kayl aimed both guns directly at the Alpha Rotling's head and pulled the triggers.

A blinding beam shot forth—Resonance Beam. Two concentrated pillars of energy roared toward the charging beast, vibrating the air, parting the mist, and cutting through the haze of the battlefield. The force of it was immense, lighting up the entire forest like a second sun had risen.

In Kayl's mind, he had already won.

He could see it—the monster's skull disintegrating into ash, the body collapsing with a dull thud, the precious loot rolling at his feet. He'd take the best items. Maybe reward his team with something minor. He deserved it. He—

A sudden blur shot across his field of vision.

Something struck his right Gatling Gun with a clang, jerking his aim just as the beam fired. Kayl's eyes widened in disbelief as the blast veered to the side. It still hit the Alpha Rotling—but only grazed its skull. The left half of the creature's head vanished into a cloud of scorched bone and blood, but the right side remained intact, twitching violently as regeneration already began.

"Sh*t!" Kayl cursed. "He's going to regenerate!"

His hands flew to correct his aim, ready to fire again even if it drained the last of his mana.

The monster was already raising its claws, fury blazing in its one remaining eye. It roared, taking a final step forward, claws poised to gut him.

Then, another blur.

But this time, Kayl saw it clearly—a bubble.

A single, translucent sphere the size of a baseball zipped through the air, shimmering with faint magical patterns. It hit the Alpha Rotling's half-regrown head with pinpoint precision.

The monster paused mid-attack, its eye flickering.

Then—

BOOM!

Its skull detonated in a shower of gore and mist. The entire head was gone now, and with it, the regenerative link that controlled the body.

The Alpha's massive form staggered. Its claws trembled in the air before falling limp. Black blood oozed from its stump of a neck. The light in its eye socket flickered once… then went out.

With a thunderous crash, the Alpha Rotling collapsed onto the forest floor.

Silence followed.

The mist stilled. The wind halted. Even the dying trees seemed to hold their breath.

Kayl, stunned, blinked at the scene before him.

"B-Bubble…?" he muttered, voice hoarse. "What the… hell?"

He turned his head slowly, searching for the source.

And there, he found him, coming out from the dead trees where the strange toy masked man was thrown.

The white masked glowed passionately in various lights, catchy songs coming out from the mask.

"Him?!" Kayl's eyes widened.
