The Protagonist's Sister Is Actually The Strongest-Chapter 444: Seeking Revenge!

-----

Because of the powers Anna had cultivated and their great vulnerability to emotional imbalance, she had to be pulled from the dark depths of despair by her family and friends. They showed her that hope still existed, even amid the crushing agony of losing someone who had become so precious to her in recent weeks.

Filled with fresh resolve, and with her powers surging stronger through the bonds and love she shared with everyone present, the power of the Heart of Hope and Love activated rapidly. It enveloped her in pink light and flames, allowing her to transform into her Venerable Form.

Her newfound resolve and awakened powers enabled her to break free from the despair that had twisted and warped her abilities into something that seemed born from the void itself. Although Anna remained unaware, those who witnessed that entity were left utterly perplexed.

Except for one—the very one who had provoked this reaction and had planned for Anna to succumb to such despair.

He had hoped she would fall into despair after he toyed with and killed her masters. He had expected that overwhelming despair to give birth to a Calamity.

Yet the outcome could not have been more different from what he had anticipated.

[The {####### ######} has fallen into slumber.]

[The {Heavenly Princess of Boundless Love} has woken up.]

“She fell into slumber?! After all that, she still didn’t give in to despair, even when I killed someone so precious to her?! W-What is this damn brat? And she… Who the hell is the ‘Heavenly Princess of Boundless Love’?! What a disgusting name! Is this… her Constellation Title?! But she isn’t even…!”

Despite acting erratic and almost foolish, Lucifer was a shrewd trickster. He enjoyed playing the clown, the beast, and the monster, but deep within his mind, he remained a calculating psychopath.

When he saw his meticulously crafted plan crumble so easily, immense frustration surged through him. He glared at Anna and her family with pure hatred.

“What is this bullshit?! Oh well, I’ll simply have to kill the rest of your wholesome friends to drag you back into despair, right? It shouldn’t be too hard!”

His voice reverberated across the world as he vanished in an explosion of darkness and reappeared above the Heavenly Empress.

His shapeless form swung countless tentacles and claws, unleashing a relentless barrage of attacks blazing with demonic flames capable of burning souls—the same flames that had incinerated the Heavenly Demon’s soul.

“{Soul-Burning Hellish Inferno}!”

It was not merely an ability but a true Demonic Skill. Even Constellations possessed such formidable powers, and one from Lucifer was nothing to underestimate. The catastrophic onslaught rained down upon the Heavenly Empress.

CLASH! CLASH! CLASH! CLASH!

“Unngggh?!”

She gritted her beak tightly as she barely held back against his overwhelming strength. Her aura erupted, and her Heavenly Divine Imperial Armament materialized—the pinnacle of Spiritual Arts—forming a colossal golden Buddha with dozens of hands, each golden palm over ten meters tall.

“{Heavenly Palms of Tranquility}!”

BAAM! BAAM! BAAM!

She countered with her remarkable technique, pushing Lucifer back slightly. Yet he persisted, rapidly opening his jaws to gather darkness, void, and demonic energy into a single point.

“You’re strong, but not enough to stand against me! Even within a vessel, I am invincible! Your beloved sacrificed his life, and even he couldn’t kill me! And you think you can do it without risking your own life?! DON’T MAKE ME LAUGH, HAHAHAHA!”

TRUUUM!

The beam struck the Heavenly Empress at near point-blank range. It was clear why he had lunged at her so swiftly—he wanted to kill her before Anna could intervene and plunge the girl into even deeper despair.

And yet…

“Foul demon, don’t look down on me!”

The Heavenly Empress roared. Her Buddha transformed into a massive golden and black shield emblazoned with the symbol of Yin and Yang at its center.

“{Heavenly Imperial Armament}: {Thousand-Layered Yinyang Aegis}!”

BOOOMMM!!!

The colossal explosion slammed into her shield, which absorbed most of the damage before shattering into fragments. It would have exploded right in front of her had she not escaped beforehand.

“What?! I thought you were a respected Venerable here, cute bird! What happened?! Running with your tail between your legs? Hah! Or should I say with your FEATHERS between your legs, hmm~?”

Lucifer grew furious as he scanned the area. The prideful Heavenly Empress had chosen to retreat rather than confront him directly, using the shield as a decoy to escape.

“Never try to make a joke again. You suck.”

“Huh?!”

His eyes widened as Anna appeared behind him. She had somehow slipped past him amid the smoke of his own attack. Her aura erupted with immense power as her Myriad Self Arts manifested dozens of her Egos, fusing and melding into a pure, rainbow-colored essence.

“{Myriad Self Arts}: {Thousand-Fold Fist}!”

Anna’s fists surged forward, striking the Demon’s body as Heavenly and Celestial flames of pink and gold burned his skin and soul. But they were not just two fists—there were a thousand of them striking simultaneously.

“GUH?!”

Unable to respond to such an absurd technique, Lucifer felt his entire body battered from every angle. The attack speed was nearly instantaneous; each of Anna’s punches was multiplied a thousandfold across his form.

He screamed in agony as his body was riddled with countless holes. Chunks of his flesh exploded and turned to ashes without end.

BOOM! BOOM! BOOM! BOOM! BOOM!

“W-WHAT IS THIS TECHNIQUE?! I-IT DOESN’T MAKE ANY FUCKING SENSE!”

Lucifer grew utterly desperate, screaming in horror and disbelief. His massive limbs and claws pointed at Anna as he tried to counter while she unleashed her technique. He pushed his regeneration to its limits, sprouting dozens of muscular demonic arms and swinging them toward her.

“{Soul-Devouring Demonic Fist}!”

BOOOM! BOOOM! BOOOM! BOOOM!

Anna took all four blows head-on without retreating. Each strike tore a piece of her soul. Yet her soul had evolved into an entirely new form. Her eyes shone brightly as she smiled with confidence.

“Bad choice.”

“BAD CHOICE?! I TOOK PIECES OF YOUR SOUL! HAHAHA! KEEP PRETENDING, I’LL DEVOUR THEM TO—GUUGH?!”

The moment he tried to devour her soul fragments, Lucifer felt excruciating pain in his guts—his real guts, within his true Demonic Body in his own realm.

He vomited blood, realizing his insides were melting as the soul fragments he attempted to consume shone brilliantly. 𝒇𝒓𝙚𝒆𝔀𝓮𝓫𝒏𝓸𝙫𝓮𝓵.𝓬𝙤𝙢

[The Fourth Wall is trembling.]

[Your current Power Level is not sufficient to consume this {Story}!]

“W-What is this?! AAAAGGH!”

He screamed in agony, witnessing countless letters, pages, and words—his entire life, his reality itself, all written in a book that encompassed everything he believed existed and what was yet to come.

This story was so vast that not even a Void Ruler could devour it, yet he had thought he could?

“Fool.”

Anna’s soul fragments glowed brilliantly and detonated within Lucifer’s true stomach, dealing direct damage to his true form, not merely his vessel.

“{Myriad Self Arts}: {Soul Ego Explosion}!”

BOOOM! BOOOM! BOOOM! BOOOM!

“AAAGGH?!”

His vessel screamed in agony, suddenly growing much weaker as the energies from his true self dwindled.

“Looks like that worked… Ah! What happened? Where did that attitude from before go?”

Anna mocked him further, enraging the King of All Demons. This was no longer a game. The sacrifice of the Heavenly Demon had already wounded his true soul, and now Anna had made that injury far worse.

“Y-YOU DAMN BITCH…! YOU AND THIS ENTIRE WORLD…! I’LL DESTROY YOU ALL!!!”

He roared and charged toward Anna. His giant body quickly developed black and red scales, and countless heads of dinosaurs and reptiles sprouted from his form.

He unfurled several draconic wings. Though monstrous and chimeric, his body now resembled an aberrant demonic dragon.

“{Seven-Headed Demonic Dragon}!”

Anna’s eyes widened as she felt an immense pressure radiating from his enormous, grotesque form. His jaws opened, unleashing seven breath attacks against her simultaneously.

“He became the seven-headed dragon already?!”

She knew quite a bit about Lucifer. After all, he was one of the foes her brother had fought in the original novel—the strongest of all demons. With over ten transformations and a battle that spanned nearly a hundred chapters, he was feared for both his overwhelming might and his near-indestructible nature.

Readers at the time had dubbed him “Cockroach” due to his resilience.

His Seven-Headed Dragon form was actually his seventh transformation. Unleashing it so quickly revealed just how desperate he had become.

FLASH!

Anna felt Gram glowing brightly. Though he had been in slumber since their last conversation, she could sense his hunger.

Lucifer’s powers were weakening, so this…

It was the perfect opportunity.

The only challenge was that she had to actually win for Gram to consume him.

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