Three thousand years ago, the Holy War raged across Britannia. The Goddess Clan, ruled by the Supreme Deity, and the Demon Clan, led by the Demon King, waged a violent war that bathed the world in blood.

That endless bloodshed changed when love sprouted across enemy lines.

Meliodas, the eldest son of the Demon King, fell in love with Elizabeth, the younger daughter of the Supreme Deity. And beside them, another forbidden bond was forged: Diablo, the second prince of the Demon Realm—younger brother to Meliodas and older brother to Zeldris—fell deeply, passionately in love with Rimuru, the eldest daughter of the Supreme Deity and older sister to Elizabeth.

For their betrayal, the two pairs of lovers faced the ultimate wrath of their godlike parents.

While Meliodas was cursed with eternal life and Elizabeth with infinite reincarnation, Diablo and Rimuru received a punishment far more insidious. Their parents combined their terrifying divine and dark powers to seal both Rimuru and Diablo away for thousands of years in isolated voids, designed to slowly erode their minds until they forgot each other's existence entirely.

Three thousand years passed.

Through sheer, terrifying willpower, Rimuru compressed every ounce of her immense divine magic into a single point, shattering her ancient seal from the inside. The price was catastrophic—the effort depleted almost all her magic, leaving her in a vastly weakened state.

When Rimuru finally emerged into Britannia, she frantically searched for her younger sister and her friend. She found Meliodas, but her heart broke when she reunited with Elizabeth's new incarnation—her beloved little sister had no memory of her at all.

Refusing to yield, Rimuru stood beside Meliodas. Together, they helped found Liones's ultimate order of knights: The Eight Deadly Sins. With Meliodas as Captain and Rimuru as Vice-Captain, she became known as the Crow Sin of Deception—feared for her unmatched tactical genius, sly intellect, and spatial magic.

Yet, a hollow ache remained in Rimuru's chest. The seal had done its damage. She could no longer remember Diablo's face or name—only a lingering sense that an irreplaceable piece of her soul was missing. Whenever Meliodas gently brought up his brother Diablo's name, Rimuru would suffer from violent headaches and suffocating heartache. Realizing the torment it caused her, Meliodas swore never to mention Diablo again until her memories returned.

Ten years ago, the Eight Deadly Sins were framed for the murder of the Great Holy Knight Zaratras and scattered to the wind.

Now, as Liones falls into the dark grips of corrupt Holy Knights, a young princess wanders in search of salvation... unaware that her big sister has been waiting for her all along.

The air inside the Boar Hat tavern was thick with the scent of spilled ale, cheap meat, and loud, rowdy laughter. High atop the grassy hill overlooking the village of Cainette, the strange, moving tavern was doing bustling business.

"Here you go, hot off the grill! The Boar Hat's famous meat pie!" Meliodas announced cheerfully, slamming a platter down in front of a table of burly villagers.

A man eagerly took a massive bite, chewed for half a second, and immediately looked like he was about to meet the Goddesses early. "THIS IS TERRIBLE!"

"Yeah, but the ale is top tier," Meliodas grinned, entirely unfazed.

Behind the bar, a girl who looked no older than fifteen or sixteen effortlessly flipped a glass in her hand, polishing it with a dry rag. She had vibrant, silky blue hair tied loosely back and bright, amber-gold eyes that seemed to read every person in the room like an open book.

To anyone watching, she was just a small, pretty barmaid. No one could possibly guess that beneath her illusionary Deception magic hid a body of graceful perfection, six towering, snow-white angel wings, and a divine magic power capable of trembling the heavens.

"Honestly, Meliodas, if you keep serving that poison, Hawk is going to have to eat the customers along with the leftovers," Rimuru said, her voice dripping with dry amusement.

"Hey! My scraps are sacred, you hear me?!" A short, pink pig trotted out from the kitchen, glaring up at her. "I'm the Master of Scraps Disposal! Respect the title, blue-hair!"

"Yeah, yeah, quiet pig," Rimuru chuckled softly, but as her golden eyes swept over the tavern, her mind was working at impossible speeds.

[Hyper-Calculation Active]

Analyzing environment... 14 patrons. 3 heavily intoxicated. 0 immediate physical threats. Magic signatures... local Holy Knight aura detected 4.2 miles west.

Still running on empty, Rimuru thought to herself, suppressing a faint sigh.

To break free from her ancient seal, she had compressed every ounce of her once-infinite magic power into a single, localized point, shattering the barrier from the inside. The escape succeeded, but it had left her drained. Her Goddess magic was completely locked away, her Devourer ability was severely restricted, and her Absolute Defense was a shadow of its former self.

And then... there was the void in her chest.

Whenever she tried to think about why she was sealed, or who had been standing beside her when the darkness took her, a searing, blinding pain would strike her head.

"Hey, Rimuru," Meliodas called out softly, stepping up beside her to wipe down the wooden counter. He leaned in, his green eyes suddenly devoid of their usual goofy charm. "You alright? You're staring into space again."

"I'm fine," Rimuru murmured. "Just thinking."

"About... him?" Meliodas asked gently, his voice barely a whisper.

BANG.

A sudden, sharp throb shattered behind Rimuru’s eyes. A wave of suffocating heartache struck her chest so hard she instinctively clutched at her vest, gasping for air. Black, blurred shadows flashed in her mind—a tall silhouette with dark hair, a crimson demon mark, a teasing smirk, and golden-orange eyes full of devotion...

"Don't," Rimuru choked out, squeezing her eyes shut until the pain slowly receded into a dull ache. She forced a breath, looking up at Meliodas with a weary smile. "Don't ask, Meliodas. You know I can't..."

Meliodas’s expression softened with a deep, tragic understanding. He knew what it was like to suffer under the cruel games of their parents. He couldn't die, Elizabeth was forced to die and forget him over and over, and his brother and Rimuru were cursed to forget the very love they fought for.

"Right," Meliodas said softly, patting her shoulder. "Sorry. Forget I asked."

Before the heavy mood could settle, the tavern doors creaked, and the loud conversations of the villagers drifted back to Rimuru's ears.

"Have you guys heard the rumors?" a patron whispered harshly. "The Wandering Rust Knight!"

"Yeah! They say it's one of the Eight Deadly Sins!"

"The Eight? You mean those terrifying traitors from ten years ago? The ones who slaughtered the Great Holy Knight?!"

"Supposedly! The Dragon Sin of Wrath, Meliodas... and the Vice-Captain, the Crow Sin of Deception, Rimuru! They say the Crow Sin could trick a god into giving up their soul before cutting their throat!"

Rimuru smirked faintly behind her glass. 'Trick a god,' huh? If only they knew.

Suddenly, heavy, metallic footsteps echoed from outside the hill. CLANG. CLANG. CLANG.

The tavern went dead silent. The patrons froze, terror paralyzing the room.

The front door dragged open slowly. Standing in the doorway was a massive, rusted suit of full-plate armor, breathing heavily, reeking of rust and exhaustion.

"The... Eight... Deadly... Sins..." a faint, hollow voice groaned from inside the helmet.

"IT'S A GHOST!" the villagers screamed, scrambling over tables and bursting out the back windows in total panic. Within five seconds, the tavern was completely empty, leaving only Meliodas, Rimuru, Hawk, and the mysterious armored figure.

THUD.

The massive suit of armor collapsed forward, crashing onto the wooden floorboards.

"Whoa, talk about an entrance," Hawk squealed, hiding behind Rimuru's legs.

"He's not a ghost," Rimuru said coolly, her gold eyes narrowing as her intellect processed the scene instantly. "Look at the posture, the weight distribution, and the magic signature. Or rather... her lack of malice."

Meliodas walked over, casually crouching down and unlatching the heavy metal helmet. As the steel slid away, long, flowing silver-white hair spilled out across the wood, revealing the pale, unconscious face of a young girl.

Rimuru’s heart stopped.

The rag in her hand slipped, falling to the floor.

[Hyper-Calculation: Facial Recognition Match]

Subject: Elizabeth.

Status: Sister (Biological - Goddess Clan).

Memory Link: Confirmed.

Rimuru took a sharp step forward, her breath catching in her throat. The physical resemblance to their mother was undeniable, but to Rimuru, this was her little sister. The girl she used to protect in the heavens.

"Elizabeth..." Rimuru whispered, her voice trembling slightly.

Meliodas looked up at Rimuru, his expression somber. "She doesn't remember us, Rimuru. Not yet. In this life, she's just the third princess of Liones."

Rimuru knelt beside the girl, gently brushing a lock of silver hair out of Elizabeth's pale face. A faint, protective warmth swelled in her chest, pushing aside the dark, painful ache of her missing memories.

"It doesn't matter if she remembers or not," Rimuru said softly, her golden eyes flashing with a sharp, dangerous resolve. "She's my sister. And nobody touches her."

The afternoon sun filtered softly through the windows of the Boar Hat's second-floor bedroom. Elizabeth slowly blinked her eyes open, her vision blurry as she met the sight of a cozy wooden ceiling.

Suddenly, she felt a soft, casual squeeze on her chest.

"Yep, heart rate seems steady!" Meliodas said with a straight face, his hand resting directly over her breast while he casually poked her cheek.

"KYAAAA?!" Elizabeth shrieked, her face turning bright red as she scrambled backward, clutching the bedsheets over her chest.

"Dumbass! What do you think you're doing to my—I mean, to the girl?!" Rimuru snapped from the doorway, smacking him on the back of the head with a rolled-up tray. "Keep those perverted hands to yourself!"

"Ow! Hey, I was just doing a medical checkup!" Meliodas rubbed his head, grinning impishly without a shred of shame.

Sitting on a wooden stool beside the bed, Rimuru blew out an irritated sigh. She turned back to Elizabeth, her golden eyes immediately softening. "Are you alright? Don't mind him, he's just an idiot."

"I-I'm fine... thank you," Elizabeth stammered, blushing furiously. She looked at the young girl with stunning blue hair tied back loosely and warm, golden eyes. She was holding a damp towel, looking at Elizabeth with a gentleness that felt strangely... familiar. A deep, instinctual comfort washed over Elizabeth, though she couldn't explain why.

"Where... am I?" Elizabeth murmured, glancing around.

"You're at the Boar Hat tavern. You collapsed from exhaustion the second you walked through our door," Rimuru smiled gently, placing the towel down on a nightstand.

"I... I see. Thank you so much for taking care of me, Miss," Elizabeth said, bowing her head politely. "My name is—"

"Elizabeth," Rimuru finished softly, her golden eyes lingering on her sister's face.

Elizabeth gasped lightly. "How did you...?"

"You're wearing the signet ring of Liones' royal family," Rimuru smoothly covered, her intellect effortlessly crafting a plausible lie on the spot. "A runaway princess in a suit of rusted armor... you must have a pretty heavy burden on those shoulders."

Before Elizabeth could answer, Meliodas popped his head into the room carrying a plate of questionable-looking food, with Hawk trotting behind him.

After a brief, chaotic meal where Hawk happily devoured Elizabeth's untouched food, Elizabeth's face turned serious. She looked at Meliodas and Rimuru with determination in her eyes.

"I am on a journey to find the Eight Deadly Sins," Elizabeth declared softly, her hands trembling slightly against her dress. "The Holy Knights... they have staged a coup d'état. They've imprisoned my father, the King, and are pushing Liones toward a senseless war. The only ones who can stop them are the Sins!"

Rimuru leaned against the doorframe, crossing her arms. "The Eight Deadly Sins were branded traitors who tried to overthrow the kingdom ten years ago. Why would you look for villains like that?"

"Because the Holy Knights are the ones causing suffering!" Elizabeth urged, her voice filled with conviction. "The Sins were heroes. Even if the world calls them evil, I believe in them!"

Rimuru's lips twitched into a faint, affectionate smirk. 'Still as stubborn and kind-hearted as ever, Elizabeth.'

Suddenly, the ground beneath the tavern violently shook.

BOOM!

A massive shockwave ripped through the air, shattering the silence of the hill. Outside, the trees were sliced clean in half by a terrifying, invisible force.

"Attention, rust knight!" a harsh, arrogant voice roared from outside. "By order of the Holy Knights, you are under arrest! Surrender or be executed!"

Down at the cliff's edge, an enormous man in heavy, spiked armor stood holding a massive broadsword. Sir Twigo—an apprentice Holy Knight—grinned maniacally as his men surrounded the base of the hill.

Elizabeth, Meliodas, Rimuru, and Hawk rushed out onto the grass. Twigo’s eyes locked onto Elizabeth, recognizing her instantly. "The third princess, Elizabeth! What a harvest! Decisive!"

Twigo swung his blade, unleashing a vacuum slice—"Judgement!"—that tore through the hillside, collapsing the terrain around them.

"Run, Elizabeth!" Meliodas called out.

Seeing the destruction and knowing Twigo was after her, Elizabeth turned and ran up the steep hill behind the tavern, her heart pounding in her chest. "I can't let them die because of me!" she thought, tears streaming down her face. "If I draw him away, they'll be safe!"

Twigo leapt high into the air, his shadow looming over the running princess. "Die, Princess!"

He brought his giant sword crashing down toward Elizabeth's back.

CLANG!

A sharp metallic ring vibrated through the air.

Elizabeth skidded to a stop and gasped. Standing directly behind her was Rimuru, holding off Twigo’s massive blade with just the sleek sheath of Tempest.

"W-What?!" Twigo gasped, his arm trembling from the sheer density of the block. "A slip of a girl stopped my blow?!"

"You're awfully loud for a third-rate knight," Rimuru said coolly, her golden eyes flashing with a terrifying, ancient coldness. With a casual flick of her arm, she repelled Twigo's massive weight, sending him tumbling back into the dirt.

Twigo scrambled up, his face twisted in rage. "Insolent pests! Judgement!"

He slashed his sword with maximum force, sending a massive, roaring wall of compressed air rushing straight toward Rimuru, Meliodas, and Elizabeth to destroy them all at once.

Meliodas casually stepped in front of Rimuru, drawing the broken dragon-head hilt from his back.

As the apocalyptic air pressure reached them, Meliodas swung the broken blade with perfect timing.

"FULL COUNTER!"

BOOM!

The attack was instantly reflected with double the power! The massive pressure blasted back into Twigo’s face, shattering his armor, snapping his sword, and hurling him hundreds of feet into the sky before crashing into the cliffside below.

A powerful gale of wind swept over the hill, whipping through their clothes.

The breeze blew Meliodas’s left sleeve up, exposing the tattoo of an Ouroboros Dragon coiled around his arm.

At the same time, the wind blew Rimuru’s long, silky blue hair aside, exposing the right side of her neck—revealing a tattoo of a Crow with its wings spread wide.

Twigo, barely conscious in the rubble, stared up in absolute horror. "The Dragon mark on the arm... and the Crow mark on the neck... It's them... The Dragon Sin of Wrath... and the Crow Sin of Deception!"

As the dust settled, Meliodas lowered his broken sword, turning back to Elizabeth with his usual goofy, unbothered grin. He casually strolled over and gave her rear a quick, shameless pat.

"Gah! Meliodas!" Rimuru shouted, instantly grabbing him by the collar and tugging him away. "Can you refrain from being a pervert for five seconds?!"

"Hey, just checking her reaction time!" Meliodas laughed, before turning to Elizabeth with a warm, genuine smile. "So, to answer your question from earlier, Elizabeth... I'm Meliodas, the Dragon Sin of Wrath. Captain of the Eight Deadly Sins."

Rimuru brushed her blue hair back over her neck, giving her little sister a gentle, protective smile.

"And I'm Rimuru," she added softly. "The Crow Sin of Deception. Vice-Captain. It looks like your search is officially over, Princess."

Elizabeth’s breath caught in her throat. Tears filled her eyes—not of fear, but of profound relief and overwhelming awe as she looked at the two legendary Sins standing proudly before her.

"I... I found you..." Elizabeth whispered, her heart swelling with hope for the first time in years.
