An Extra’s Rise in an Eroge

Arthur didn't waste time. The moment he stabilized himself, he shot forward like a bullet, his feet barely touching the ground as he closed the gap between him and Zeke. The abyssal fang pulsed with dark mana, and with a single swing, a black crescent-shaped energy slash hurtled toward Zeke.

Zeke reacted instantly, sidestepping the attack before lunging forward with a precise thrust aimed at Arthur's chest. Arthur twisted his body, narrowly avoiding the blade, and countered with a downward slash. Zeke blocked it, their swords locking for a brief moment before he pushed Arthur back with raw strength.

Arthur didn't hesitate. The black tendrils of his symbiote erupted from his back, launching him forward at an unnatural speed. His body maneuvered fluidly, weaving through Zeke's strikes while his own attacks became more unpredictable. The symbiote extended, forming temporary blades that lashed out at Zeke from different angles. Zeke gritted his teeth as he parried and dodged, his movements sharp but clearly being pressured.

"Tch! What the hell are you?!" Zeke growled, frustration creeping into his voice.

Arthur didn't answer. Instead, he cast Firebolt, sending a flaming projectile toward Zeke's face. Zeke tilted his head to dodge, but Arthur had already closed the distance, swinging his sword at Zeke's exposed side. Zeke barely managed to block, but the impact sent vibrations up his arm.

Arthur wasn't letting up.

He enhanced his legs with mana and kicked off the ground, flipping over Zeke while slashing downward. Zeke ducked, rolling to the side, but Arthur's symbiote tendrils extended mid-air, grabbing onto the floor and yanking him in a different direction, allowing him to attack from Zeke's blind spot.

Zeke reacted at the last moment, raising his sword just in time to block. But Arthur was faster now—his wounds healed almost instantly as the symbiote mended his injuries, and his attacks didn't slow down. The abyssal fang's dark aura flared violently, forcing Zeke into full defense.

With every clash, Zeke was getting pushed back.

Arthur's attacks became relentless—his symbiote created more tendrils, striking from different angles while his swordsmanship and magic overwhelmed Zeke's defenses. A well-placed tendril wrapped around Zeke's arm, yanking him forward just as Arthur's blade slashed across his chest.

"Argh!" Zeke staggered back, blood dripping from the deep gash.

Arthur's eyes locked onto him, predatory and cold. Zeke realized too late—he had no more room to escape.

The symbiote surged over Arthur's body, engulfing him in a monstrous, black form with glowing white eyes and jagged fangs. With unnatural speed, Arthur lunged.

Zeke barely had time to scream before Arthur's jaws clamped down on his head.

A sickening crunch echoed through the museum as Zeke's body twitched violently before going limp.

Silence fell.

Arthur stood there, his monstrous form dripping with blood, his breath heavy.

"Arthur!"

A blade nearly struck him, but Arthur instinctively leaped back, retracting the symbiote just in time to reveal his normal form.

Samantha stood there, sword raised, her expression twisted in shock and horror.

"That sword—it's taken over you!" she shouted, preparing to attack again.

Arthur raised his hands, panting. "Wait! It's me. I'm in control."

Samantha hesitated, her grip on the sword tightening. Her eyes flicked between Arthur and the abyssal fang still pulsing with dark energy.

Arthur exhaled, retracting the last bits of the symbiote back into his body, his form completely returning to normal.

Samantha lowered her sword slightly but remained tense. "We're going to have a long talk after this."

Arthur nodded, wiping the blood from his face. "Yeah… I figured."

On the other side.

Elven Princess Nyra stood firm amidst the raging battle, her glowing bow crackling with ethereal energy. With each precise pull of the string, a magical arrow materialized, soaring through the air and striking its target with unerring accuracy. Every movement was fluid, every shot a perfect execution of skill honed over years of training.

By her side, Cassandra wielded a newly acquired weapon from the Royal Museum, its power amplifying her magic. With a flick of her wrist, she unleashed torrents of fire, incinerating the oncoming monsters in a blazing inferno. Meanwhile, Alex cut through the creatures with practiced efficiency, his blade slicing through flesh and bone without pause.

They had been fighting since the beginning of the assault. Fatigue gnawed at their bodies, but stopping wasn't an option. The only choice was to push forward, to endure.

Just as Nyra prepared another arrow, a sudden shift in the air sent a chill down her spine. Something was coming. Fast.

Reacting on instinct, she abandoned her bow and raised her left hand.

"Spirit Guard!"

The ring on her finger pulsed with magic, conjuring a spiritual barrier around her. The moment the shield formed, a powerful force crashed into it.

CRACK!

The barrier shattered instantly, the impact sending shockwaves through her body. Dust erupted around her as she staggered back, trying to regain her footing.

Alex, sensing the danger, was already moving. His eyes darted around, sword at the ready.

As the dust settled, Nyra found herself gripping a shield—one that had barely intercepted a spear aimed directly at her. The weapon radiated ominous energy, a clear sign that this was no ordinary attack.

Cassandra rushed to her side. "Nyra! Are you okay?"

Nyra leaned against the shield, her breath steadying as the initial shock wore off. Pain throbbed in her arms, but she pushed it aside. The shield—a gift from her mother—had absorbed the brunt of the attack. Without it, she would have been in serious trouble.

A mocking voice rang out from the battlefield.

"I really thought that would kill you. But I guess a princess like you has some 'good' toys, huh?"

Nyra's gaze snapped toward the source of the voice. A fiery-haired woman strode forward, her expression unreadable, yet exuding confidence.

Nyra immediately raised her guard. "Who are you?"

Before the woman could answer, Alex scoffed. "Why bother? She's already dead." Without hesitation, he charged forward, sword aimed to end the fight before it began.

Ava smirked. "Kids these days… no respect for their elders."

Just as Alex closed in, a surge of mana erupted from Ava's body. In a blur, she vanished from her spot.

What—?!

Alex barely had time to react before she reappeared in front of him, her spear thrusting forward with explosive force. He raised his sword just in time to block, but the impact sent him flying backward, slamming into the ground with a heavy thud.

"Alex!" Cassandra's voice rang with panic.

Wasting no time, she fired a flaming arrow straight at Ava's shoulder, the spell crackling with amplified power. But the moment it neared its target—

Fwoosh!

The fire vanished into nothing, leaving behind only a faint trace of smoke.

Cassandra's eyes widened. What just happened?

Ava tilted her head, amused. "That's cute."

Alex stood back up and lunged forward, closing the distance in an instant. His sword cut through the air in a diagonal arc, aimed to cleave through his opponent.

This should be enough to at least slow her down—

But the moment his blade made contact, something was off. His strike, which should have sliced through flesh, met no resistance. It was as if he had struck an illusion.

Ava didn't even attempt to dodge. She stood there, smiling—a chilling, twisted grin that sent a cold shiver down Alex's spine.

What the hell…?

A sinking feeling settled in his gut. No matter how strong an opponent was, there should have been some reaction—some flinch, some movement. But she remained completely unfazed, as if she were toying with him.

He needed time to figure this out, but time was a luxury they didn't have.

With an eerie giggle, Ava turned her attention toward Nyra.

"Come on, entertain me a little more!" she said, her voice laced with excitement.

Nyra tensed, her grip tightening on her bow. Cassandra stood beside her, her face stiff with fear.

Chweek— Chweek—

She unleashed spell after spell—flaming arrows, fireballs, bursts of mana. Each attack was aimed to slow Ava down. Yet, she didn't even try to evade them. Every single strike landed, yet none had any effect.

Ava simply continued walking forward, her eerie grin never fading.

Cassandra's stomach twisted. Nothing's working…

Despair settled in as the realization hit them—no matter what they did, their attacks were useless.

And then—

Ava released a sudden surge of magic, raw and suffocating. The sheer force of it was like a raging storm, pressing down on them like an invisible weight.

The pressure alone made it difficult to breathe.

Then—

BOOM!

Alex was sent flying before he could react, his body crashing through the air like a ragdoll. His scream was lost in the explosion of force as he was violently thrown across the museum, slamming into a wall with a sickening impact. Experience tales at My Virtual Library Empire

"Alex!" Cassandra's voice cracked with panic.

Dust and debris filled the air, but through it, she could see her brother, barely moving.

"Ugh..."

Despite the pain, Alex groaned and forced himself up, his body trembling. Blood dripped from a cut on his forehead, his vision slightly blurred, but he refused to stay down.

Cassandra rushed to his side. "Are you okay?!"

Alex wiped the blood from his face, forcing a pained smirk. "Yeah… just peachy."

But even as he stood, the truth was undeniable.

They were completely outmatched.

"Move!"

A sharp voice cut through the chaos.

Nyra didn't think—she just reacted. Her body moved instinctively before her mind could catch up.

BZZZT!

Something whizzed past her, crackling with electricity, and slammed straight into the red-haired woman.

BOOM!

A deafening explosion followed, sending a shockwave through the museum. The impact forced Ava to stagger, her movement momentarily halted.

All eyes snapped toward the source of the attack—Arthur. He stood firm, his pitch-black sword in one hand, his other arm still extended from the throw. His gaze locked onto Ava with cold precision.

Nyra, Cassandra, and Alex quickly turned their attention back to their enemy.

There she was—pinned to the wall. A spear had pierced through her chest, impaling her like a trophy. Faint arcs of electricity crackled along its shaft, zapping through her body in erratic pulses.
