The Protagonist's Sister Is Actually The Strongest-Chapter 445: Demon War

-----

“Alright then, let’s do this. Song, Mom, Fang Shuan! You guys ready?”

They hovered high above the skies, recovering their strength and waiting for the right moment to strike. Bringing Anna back to normal had drained a great deal of their energy, and the Heavenly Empress was still wounded and in need of proper healing.

“We’re ready, Anna!” Song called out.

“Any time,” the Heavenly Empress replied.

“Of course, young lady,” Fang Shuan nodded.

“Good…”

Anna nodded as the beams rushed toward her. Her Myriad Self Arts shifted and merged with the cloud of nanomachines flowing from her own body.

Myriad Self was a versatile technique that could combine and adapt to any ability she possessed.

The nanomachines she had injected into herself had been multiplying slowly over time, growing stronger as her own power increased.

Now she fused them with Myriad Self Arts and several other machine-related skills.

The result was devastating.

“{Myriad Self Arts}: {Demonic Energy-Reflecting Lotus Mirrors}!”

Seven mirrors of rainbow-colored metal materialized around her, spinning rapidly. As Lucifer’s breath attacks struck, the mirrors reflected every blast.

FLASH! FLASH! FLASH! FLASH!

“WHA…?!”

Lucifer stared in shock. His own attacks were hurled back at him, each beam now infused with power from the mirrors and glowing in vibrant rainbow and golden hues.

Anna had combined Demonic Energy and Celestial Energy within them. The two opposing forces created something far deadlier.

The beams suddenly turned black, swirling with distorted energies that warped space itself.

“CHAOS ENERGY?!”

As Lucifer tried to maneuver his massive body away from the reflected beams, a voice rang out.

“Where do you think you’re going?!”

Song appeared in a blaze of unique aura, a perfect harmony of his father’s and mother’s powers.

A giant ring manifested behind his back, resembling a constantly rotating Yin-Yang symbol surrounded by glowing Chinese characters and Feng Shui talismans.

Lucifer felt the lingering power of the crow he had once killed radiating from the young man, and it shook him.

“{Divine Domain of White and Black Heaven’s Balance}!”

Song roared as he created a small domain around himself and half of Lucifer’s enormous body. Light and darkness merged into harmonious energy, pushing the demon back and burning his flesh with black and golden flames.

Song followed up with powerful kicks to Lucifer’s many heads and a heavy punch to his chest. Countless explosions of white light and darkness erupted across the demon’s body, covering him in Holy Curse Symbols that drained his energy and transferred it back to Song.

With precious seconds bought, Song leaped away just in time. The seven beams of chaos energy—the reflected breath attacks—slammed into Lucifer with overwhelming force, piercing his body seven times.

He vomited blood from all his heads as his guts spilled across the sky. His colossal form suffered catastrophic damage. Chaos flames raged across his entire body, devouring his energy output even further.

“You will pay for what you did to the only man I’ve ever loved.”

“AH?!”

The King of All Demons received no respite. The Heavenly Empress returned for vengeance, her Buddha manifestation appearing once more, but changed.

One half resembled a furious god of the underworld, wielding massive blazing axes wreathed in spectral crimson flames. Darkness and light converged within the Imperial Armament Manifestation.

While one side mirrored her original Imperial Armament Summon, the other half looked exactly like the Heavenly Demon’s “Demonic Ruler of the Underworld: King Yanma”!

“FUCK OFF!”

Lucifer screamed, sprouting a massive draconic head from his chest and preparing to unleash a colossal breath attack with everything he had.

Yet before he could release it—

“{Perpetual Cycle of Harmony Arts}: {Underworld of Perpetual Silence}!”

The King Yanma side moved at blinding speed, manifesting its own pseudo-domain. Space twisted and warped as the sky turned black. Spectral beings resembling black crows appeared out of nowhere, swarming toward Lucifer and wrapping him in cursed flames.

“W-WHAT IS THIS…?!”

His breath attack never left his jaws. His mouth was suddenly sealed shut. The built-up flames and power inflated his chest like a balloon until he exploded from within.

BOOOMMM!!!

Half of his body was instantly blown to pieces. The Heavenly Empress did not stop there. The other half of her Armament struck relentlessly, slamming the remains of his body with dozens of palm strikes.

Each blow connected to star-like symbols that floated around him, symbols he could not comprehend.

“{Perpetual Cycle of Harmony Arts}: {Glistening Constellation of Hope}!”

FLASH! FLASH! FLASH! FLASH!

All the stars aligned at once, forming a beautiful constellation shaped like the Heavenly Demon’s silhouette. As the Heavenly Empress shed a tear, the giant constellation moved, raining down punch after punch on Lucifer.

“Take revenge on him, my love!”

BOOM! BOOM! BOOM! BOOM!

She roared through her tears while the demon screamed in agony. Each strike tore away pieces of his vessel’s soul, distorting his demonic energy and making it grow dangerously unstable without a proper container.

“D-DAMMIT! AAAAAAAGGH!”

As Lucifer was battered with almost no chance to retaliate, Anna appeared behind him. Her Myriad Self Aura manifested countless hands to wield her many weapons at once.

“Missed me?!”

“G-GET AWAYYYY!”

The demon screamed and spread his Demonic Domain in desperation. Everyone was suddenly pulled into an infernal landscape as space distorted and warped.

FLAAASH!

Even as the ground trembled and giant demonic hands rose endlessly from the flames, Anna did not slow down. She reached him in an instant.

“{Demonic Inferno Domain}: {One Thousand Demonic Hands: Legion}!”

Lucifer summoned another demon from nowhere. Legion was a being made entirely of one thousand different hands.

They swarmed Anna, grabbing her and forcing her down into the infernal flames. They punched and attacked her relentlessly, trying to burn her to ashes.

BAAM! BAAM! BAAM! BAAM! BAAM!

“ANNA!”

The Heavenly Empress panicked as her constellation-like Armament suddenly collapsed. Another demonic being had been summoned.

It was a giant demon with fiery red skin, six muscular arms, six blazing weapons, three faces, and six horns on his bald head. His lower body was that of a giant black horse, with a tail resembling a massive purple-scaled snake.

“{Demonic Inferno Domain}: {Three-Faced Bloodthirsty Warlord: Centurion}!”

Song watched from above in surprise, realizing they were all trapped inside the domain. He dove down, only to be halted by yet another summoned creature.

“Don’t think I forgot about you, pretty bird!”

Lucifer laughed as the giant being attacked Song with a relentless barrage of punches, kicks, and sharp scythe slashes that sliced through his feathers at terrifying speed.

The demon looked like a giant humanoid red mantis with four enormous scythes, an insectoid head, sharp mandibles, and long antennae.

“{Demonic Inferno Domain}: {Four-Bladed Warrior of the General of the Burning Battalion: Morax}!”

With three powerful demons now summoned, Lucifer’s vessel gained precious time to begin regenerating his wounds.

“Heh, this is amateur-level shit, Lucifer.”

Anna’s calm response made Lucifer’s many eyes widen in disbelief. Her blades moved at lightning speed, slicing and shredding through hundreds of gigantic arms one after another.

“{Heavenly Myriad Blade Arts}: {Starlight Spiral}!”

SLASH! SLASH! SLASH! SLASH! SLASH! SLASH!

Her attacks multiplied and condensed into a brilliant spiral of cosmic light that surrounded her as she advanced toward Lucifer, cutting through Legion without pause.

“LEGION, YOU BASTARD! ARE YOU GOING TO DIE NOW?!”

Furious, Lucifer roared as Legion pulled back its remaining arms and fused them within the sea of flames. A gigantic arm with countless fingers, eyes, and jaws emerged.

RUMBLE!

“GRUOOOOHHHH!”

Lucifer smiled confidently.

“Heh, that ought to keep her entertained for the moment and—Huh?!”

Out of nowhere, he found himself surrounded by several demons he had not summoned. Their powers felt strangely altered.

“You’re…?!”

He recognized them immediately. They were half of the Death Apostles he had been hunting—deserters from his own worlds who dreamed of building a new demonic realm separate from the 999 hells he ruled.

“Long time no see, Your Majesty! You look mighty fine right now, riddled with holes!”

Astaroth.

“I never thought I would get the chance to fight you…!”

Aim.

“While Anna’s busy, let’s buy her some time.”

Bael.

“How about we just steal the whole show instead?”

Agares.

“I-I am not related to you at all! I’m sorry! I’m being forced to do this!”

Jeremias.

“RAAAAAHHHHH!”

And Nemesis.

“You damn fucking traitors… You’re less than shit, and you think you can challenge me?! You’ll be lucky if I turn you into my cute little pets! Maybe after I rip out your eyes and cut off all your limbs so you can never escape again!”
