Buzz—!

A dazzling blue light suddenly erupted, centered on Sona.

From within the light, five figures identical to Sona materialized out of thin air!

This sight instantly caused everyone on the battlefield to widen their eyes in shock.

A Avatar technique?

But right after that, something that astounded them even more took place.

After these five Avatars appeared, they didn't draw weapons and charge at the enemy like warriors.

Instead... they pulled out musical instruments?

A wild electric guitar, a heavy bass guitar, a sci-fi synth keyboard, a photonic drum kit, and a golden trumpet.

Each Sona held a different musical instrument in her hands.

Sona's true body gently held a standing microphone, taking her place at the very center of the band.

The top of the shipping container instantly transformed into a dazzling stage.

"W-What... what is she doing?"

Wang Zhenbei was completely baffled.

He had fought all his life and seen countless strange professions, but he had never seen anyone hold a concert in the middle of a battlefield!

"Cheap tricks!"

Below, the Sakura Country commander snapped back to his senses, a trace of cruelty flashing in his eyes. "Blow that stage to smithereens! Blast those women into dust!"

"Rumble—"

The barrels of several heavy Magitech Tanks slowly raised, their pitch-black muzzles locking onto Sona at the top of the container.

However,

"On this stage..."

"...there is only my voice."

Sona's true body suddenly snapped her eyes open. Storms seemed to brew within her sapphire-like eyes.

The drummer Avatar raised her drumsticks high, and then—

Brought them down hard!

"BOOM!!!"

This drumbeat was no longer muffled like before.

Amplified by the skill 【Phantom Band】, it exploded in everyone's ears like a heavy bomb!

A near-tangible shockwave of sound radiated frantically outward in a ring from the container!

Under the impact of this horrific soundwave, the Magitech Tanks that had just adjusted their muzzles shuddered violently, their barrels jolted off target.

Right after,

The deep rumble of the bass, the sharp scream of the guitar, the psychedelic melody of the keyboard...

All the instruments burst into sound simultaneously!

This was no elegant classical music.

Nor was it some soft pop song.

This was the purest, wilder, most blood-boiling sound of all—heavy metal rock!

"BOOM! BOOM! BOOM!"

The violent rhythm surged like thousands of galloping horses, instantly drowning out all gunfire and artillery on the battlefield.

Sona gripped the microphone, her body swaying to the rhythm.

The moment the first note burst from her lips, all of Cloud Port seemed to stand still.

It was a voice beyond description.

High-pitched, penetrating, and brimming with endless power and hope.

Wherever the soundwaves swept, a miracle occurred.

At Dock No. 1.

Chen Xiaohu, who had been completely exhausted and unable to even lift his blade, suddenly felt his heart constrict sharply. Immediately after, a surge of scalding heat pumped from his heart, flowing through his entire body in an instant.

It felt like downing a whole bottle of hard liquor in the dead of winter.

Or like a dying fish returning to the ocean.

"Ah..."

Chen Xiaohu let out a groan, realizing with astonishment that his legs, which had felt as heavy as lead, now felt extraordinarily light.

The depleted mana inside him was recovering frantically at a terrifying speed.

It wasn't just him.

Across the entire Northwest Army Vanguard Regiment, thousands of soldiers lit up with multi-colored light at that very moment.

Red light signified a massive surge in strength.

Teal light signified a dramatic boost in speed.

Blue light signified mana restoration.

And most miraculous of all was the green light.

The bloodied soldiers covered in wounds watched in shock as their injuries stopped bleeding, scabbed over, and healed at a visible pace!

Even a young soldier whose leg had been blown off and who had been lying in a pool of blood waiting to die felt the excruciating pain at his stump fade, replaced by an itchy sensation as vitality rushed back into his body.

"W-What... what is this?"

Wang Zhenbei stared blankly at his own hands.

He felt as though he had returned to his twenties, back to the Peak period when his vitality was highest and his energy most abundant.

No!

Even stronger than back then!

He suddenly raised his head, looking at the figure singing her heart out under the lights atop the shipping container.

The young girl he had dismissed as a mere decorative vessel now looked to him like a Valkyrie descended upon the mortal realm!

"W-What on earth is this profession?"

"To think it has such horrifyingly powerful buff effects!"

Wang Zhenbei muttered to himself. Then, ecstatic joy erupted across his face—a long-suppressed burst of pure jubilation.

"Hahaha! Good! Excellent!"

"Brothers! Do you feel it?!"

Wang Zhenbei's voice thundered out through a break in the music.

"We feel it!!"

Thousands of Northwest Army soldiers roared in unison. Their voices held no fatigue, no despair—only skyrocketing Battle Intent!

"Then charge, dammit!!"

Wang Zhenbei swung his blade with his single arm, pointing forward at the stunned Sakura Country defenders.

"Hack these sons of bitches to pieces for me!!"

"Kill!!!"

This charge was vastly different from before.

Having received massive buffs to all stats, the Northwest Army was like a pack of prehistoric beasts on stimulants.

Chen Xiaohu charged at the forefront. Out of ammo for his magitech rifle, he swung it like a club, smashing it hard against an Oni Warrior before him.

"Bang!"

The armor shell, which should have been exceptionally tough, actually caved in from his rifle-butt strike!

"Holy shit! Am I really this fierce?"

Even Chen Xiaohu startled himself, before turning overjoyed. Drawing a dagger from his waist, he pounced into the enemy ranks like an agile leopard.

Meanwhile, on the other side of the battlefield...

The Sakura Country defenders were experiencing the exact opposite.

To their ears, the exhilarating music sounded like a death knell.

Although Sona's skills mainly buffed allies, the high-decibel sonic blast combined with the soul-shaking rhythm made their hearts pound wildly, severely disrupting their casting concentration.

An Onmyoji had just attempted to summon a Shikigami when the sudden roar of the bass caused his hand to tremble. The Talismanic Incantation immediately burned to ash, and the backlash made him cough up a mouthful of blood.

"Baka! What kind of Demonic Art is this?!"

Watching the Northwest Army—which had been on the verge of collapse just moments ago—instantly turn full of vigor and even double their combat power, the Sakura Country commander completely lost his composure.

"Stop them! Fire the cannons! Blast that singing woman to death!"
