Five years passed in what felt like the blink of an eye.
The Einshorn household had changed.
The village had changed.
The world itself had unknowingly changed…
But Arthur?
Arthur had become a monster hiding in plain sight.
No one—no one—could comprehend just how dangerous the small, calm, black-haired boy really was.
By age five, Arthur could:
Cast high-ranked spells without incantations
Summon black flames that defied nature
Split boulders with a finger
And manipulate light AND dark mana cores at will
To the outside world, he was a young prodigy, a future hero.
To himself, he was still the same thing:
The rightful heir to the Demon King's throne.
Of course, he still couldn't break the damn seal.
He'd attempted it 1,342 times.
Alfred had survived all 1,342.
Which frankly annoyed Arthur.
The sun rose, peaceful and warm.
Then Anna kicked the bedroom door open.
"BLISS! ELSA! EVERYONE! ARTHUR IS MINE TONIGHT! I CALLED DIBS!"
"You called nothing, idiot!!" Elsa shouted, leaping off the stairs as if performing a wrestling move.
"He's sleeping with me tonight!"
"You slept with him yesterday," Bliss said flatly from across the hall.
"It's my turn."
"You don't even cuddle!" Anna snapped.
"That's why he likes it."
Anna fell silent. Grim truth.
Arthur emerged from his room, brushing his hair with the elegance of a tiny villain.
"…Can you all lower your voices? You're giving me a migraine."
The girls froze.
Then—
"KYAAAAA!! HE SAID MIGRAINE!!! HE'S SO CUTE WHEN HE TALKS LIKE A GRANDPA!!!"
Arthur's eye twitched.
If I unleashed a single dark tornado right now, I could silence all of them. Forever.
But he resisted, because—
From behind him, Bliss stepped out of the room, adjusting her long dark hair.
She spoke softly, "Arthur… breakfast."
Arthur nodded immediately.
He always softened around her without realizing it.
The other sisters glared daggers at Bliss.
Bliss didn't care.
She took Arthur's hand gently—he didn't pull away—and led him downstairs.
Anna whispered, "Why does she get to hold his hand?!"
Elsa hissed back, "Because he doesn't kill her when she does it!"
"…That's a good reason."
Alfred, the "great hero," walked in loudly as usual.
"GOOD MORNING, MY BEEEEEELOVED SO—"
A fireball struck him square in the face.
BOOM.
Alfred went flying through the nearest wall into the garden.
Arthur elegantly blew imaginary smoke from his fingers.
"Oops," he said with zero remorse.
"Sorry, Father. Spell slipped."
Melda didn't even look up from the frying pan.
"That's your fault for talking too loud in the morning, dear."
Arthur smirked.
Bliss sipped her tea, lowering her voice just for him.
"That's attempt number…?"
"One thousand three hundred forty-three," Arthur answered casually.
"Disappointing. He still lives."
Bliss nodded sympathetically.
"Mmm. He is durable. Like a cockroach."
Arthur almost choked on his drink.
He coughed, staring at her with wide eyes.
"…Bliss, your insults are improving."
She didn't smile, but her ears turned pink.
"I study."
The other sisters froze.
That was the Bliss equivalent of "I adore you."
Arthur turned away dramatically.
"…Whatever. It's not like I care."
But his cheeks had the faintest pink tint.
Anna and Elsa clutched their chests.
"He BLUSHED. OH MY GOD."
"BLISS IS WINNING."
"THIS IS NOT FAIR."
Arthur raised a finger toward them, dark mana crackling dangerously.
They shut up immediately.
After breakfast, Arthur slipped away to the forest behind the house—his private training ground.
He summoned a huge magic circle that stretched across the earth, swirling with runes no human had ever witnessed.
"Attempt one thousand three hundred forty-four…"
Dark lightning ripped the sky apart.
A vortex of purple flames spiraled upward.
A crack in space trembled—
And then—
Fzzzzzp.
The spell fizzled out like a wet sparkler.
Arthur stared at the tiny spark.
"…This body is still so weak."
He kicked a tree.
The tree disintegrated.
He sighed dramatically.
"I must acquire more mana, more spells, and more—"
He sensed a quiet presence.
He turned sharply.
Bliss stood there, hugging her knees, watching him.
"…You were crying," she said softly.
Arthur froze.
"I– I do NOT cry."
"Yes, you do. On the inside."
He opened his mouth—
Then closed it.
Then opened it again.
"…So what if I was frustrated," he muttered.
Bliss approached.
Quiet as the night.
Gentle as snow.
She placed a hand on his shoulder.
He felt a warmth that contradicted his entire nature.
"I don't know why you're trying so hard," she said quietly.
"But if you want strength… then I'll help you."
His heart skipped.
"What can you possibly do?"
She shrugged.
"Stand beside you."
Arthur looked away quickly, ears red.
"Tch. That's… stupid. That won't help anything."
But he didn't push her hand away.
Not this time.
Bliss sat beside him in silence.
He found, to his horror, that it was… comforting.
Enough that the storm in his chest eased.
Enough that he didn't think about slaughtering humanity for a whole five minutes.
Enough that he whispered, barely audible—
"…Thank you."
Bliss smiled.
A tiny, soft smile she only ever showed him.
And Arthur felt something terrible.
A small piece of his heart—the black, rotten, demonic heart of a future tyrant—
began to glow.
Just a little.
He hated it.
He loved it.
He didn't understand it.
But he didn't push it away.
Not when she was around.
Here is a long, dramatic, intense, emotional, funny, and well-paced version of the full scene you described—complete with battle, dialogue, character depth, and Arthur's internal conflict.
Arthur stepped into the woods with a scowl on his face.
He was supposed to be secretly performing Attempt #1,345: Breaking the Seal, but Alfred had dragged him into "father–son training" earlier, so Arthur had only managed to bury Alfred neck-deep in a crater before Melda scolded him.
So now Arthur walked deeper and deeper into the forest, muttering to himself:
"Stupid hero. Stupid human body. Stupid seal. Stupid everything."
He was about to begin his spell when—
A scream tore through the trees.
A girl's scream.
High-pitched. Terrified.
Arthur froze.
"…Nope. Not my problem."
He turned away, preparing his spell circle.
Another scream.
"…Still not my—"
Then he heard laughter.
Men's laughter.
Sick, twisted laughter.
Arthur's eyebrow twitched.
"…Tch. Humans."
His curiosity—and disgust—won.
He walked toward the noise, staying silent as a shadow.
A clearing opened.
A small elf girl—white hair, emerald eyes, tiny pointed ears—ran through the grass, panting. She tripped and fell.
Three adult bandits surrounded her.
She looked Arthur's age—maybe five or six. But elves matured slowly.
One bandit grabbed her by the wrist.
"Cute little elf. Bet the slavers will pay top coin for you."
Another leaned closer, licking his lips.
"Or maybe we have some fun first."
The girl trembled violently, hugging herself.
"P-Please! Let me go! I—I didn't do anything—!"
Arthur watched from behind a tree.
Expressionless.
Emotionless.
Until the bandit grabbed the front of her dress—
Arthur stepped out.
Calmly. Quietly. Hands in his pockets.
The bandits blinked at him.
"A kid?"
"Aww, look at that. A little hero."
"You lost, boy? Wanna join the elf?"
The elf girl looked at Arthur desperately, tears streaking her cheeks.
"P-Please… h-help…"
Arthur sighed.
"Ugh."
He didn't want to help.
He didn't want involvement.
He didn't want more people knowing he existed.
But this?
THIS, he couldn't tolerate.
He cracked his knuckles.
"You filth are really testing my patience today."
The bandits burst into laughter.
"Oooh! Scary kid!"
"Look at him tremble."
Arthur wasn't trembling.
His mana was.
The largest bandit lunged, swinging a club at Arthur's head.
Arthur didn't move.
He flicked a finger.
A ripple of dark mana shot outward—
CRACK
The club shattered into dust.
The bandit stumbled back, staring at his empty hands.
"H…How…?"
Arthur looked bored.
"That was me holding back. If I use even ten percent of my strength, you will simply cease to exist."
Another bandit charged with a dagger.
Arthur slid one foot back and whispered:
"Shadow Bind."
Black tendrils erupted from the bandit's own shadow, coiling around his legs, arms, chest—slamming him to the ground with bone-cracking force.
He screamed.
The elf girl covered her ears.
The third bandit panicked, grabbing the girl as a hostage.
"D-don't come closer! Or I'll—"
Arthur blinked slowly.
"You shouldn't touch what doesn't belong to you."
"Or what?" the bandit barked—
Arthur raised a hand.
A magic circle of pure darkness appeared.
"I'll show you something fun."
"D-Dark magic?!" the bandit gasped.
Arthur whispered:
"Nightmare Blight."
The bandit froze.
His pupils shrank.
His breath hitched.
He dropped the elf girl as he began screaming at hallucinations only he could see.
Arthur walked up to him calmly and tapped him with a single finger.
BOOM.
A shockwave knocked the man out cold.
The clearing became silent.
Only the rustle of leaves remained
The elf girl stared wide-eyed at Arthur.
Like he was a god. Or a monster.
Probably both.
Arthur turned away.
"There. You're safe. Now go home."
The girl scrambled up and grabbed his sleeve.
"W-Wait! Please… don't leave me alone!"
Arthur groaned loudly.
"Why must you creatures be so clingy…?"
She bowed deeply, shaking.
"M-My name is Emir! I—I got separated from my caravan… please! I don't know the way back!"
"Ask someone else."
"I'll die if I stay here alone!"
"…Not my problem."
"Pleeease!"
Arthur pinched the bridge of his nose.
"Fine. I'll escort you to your precious Clover Kingdom. Then leave me alone."
Emir brightened instantly.
"Oh! My home isn't in Clover Kingdom!"
Arthur stopped walking.
"…Then where is it?"
"A place called Reed Village!"
Arthur blinked.
"That's… a human settlement."
"Yes!"
"…You're an elf."
"Yes!"
"…Why do you live with humans?"
"Because my mama fell in love with one!"
Arthur stared at her as if she were a walking complication.
"…Gross."
Emir giggled.
"You're funny!"
"I'm not."
"You are!"
Arthur exhaled sharply.
"I'm only helping because the situation was disgusting. Don't misunderstand, elf."
"My name is Emir!"
"Whatever."
But as they walked—
Emir kept smiling at him.
Talking to him.
Giggling at his dry comments.
Skipping beside him like an excited puppy.
Arthur found himself… responding.
Just a little.
"…I'm Arthur."
Emir's eyes sparkled.
"That's a great name! It sounds strong!"
"Of course it does."
"Are you a hero?!"
"Absolutely not."
"Then… are you a villain?!"
Arthur nearly choked.
"…What kind of child asks that?!"
Emir poked his cheek.
"You feel like both!"
Arthur swatted her hand away.
"Stop touching me!"
"Hehehe!"
He glared at her but… didn't scare her.
She liked him.
Way too much.
And Arthur, the demonic prince who wanted nothing but destruction—
Found himself sighing softly.
"…Tch. What an annoying elf."
But he didn't let go of her hand.
He held it tightly as they walked to the village.
Arthur and Emir walked down the dirt path toward the human village.
Emir kept skipping, humming, stumbling, grabbing Arthur's arm, chattering about anything she saw.
Arthur endured all of it with the patience of a slowly dying saint.
"…Can you walk in a straight line for five seconds?"
"That's impossible!" Emir declared with confidence.
Arthur sighed.
Humans. Elves. All the same. Annoying.
But when she nearly tripped on a pebble, Arthur instinctively grabbed her hand before she fell.
Her fingers wrapped around his.
Warm. Soft. Trusting.
He almost let go—
But didn't.
"T-Thanks, Arthur."
"It was purely to prevent you from slowing us down."
"Uh-huh," Emir giggled.
Ugh.
This elf was dangerously skilled at disarming him without even trying.
Reed Village came into view: a peaceful settlement with wooden houses, fields of wheat, and humans who stared at the elf girl returning home.
"EMIR!!"
A tall human woman sprinted out of a house, her eyes full of tears.
"MAMA!"
Emir leapt into her arms, hugging tightly.
A second figure appeared — an elf man with silver hair and calm, gentle eyes.
He saw Arthur.
Before Arthur could escape, Emir pointed dramatically:
"Mama! Papa! HE saved me!"
Arthur froze.
"No. I didn't. I just—"
The elf father marched toward him with terrifying speed.
Arthur prepared a spell, ready to blast him into orbit if needed—
But instead, the elf father grabbed his hands.
"THANK YOU, BRAVE YOUNG HUMAN!!"
Arthur recoiled like he'd touched acid.
"Ugh—don't hold me."
The human mother joined in, hugging him tightly.
"You saved our baby girl… oh, you sweetheart!! How old are you? Five?! You're such a little hero!"
"I am not—!"
Emir clasped her hands behind her back, smiling brightly.
"Isn't he amazing? He beat the bad guys like—BAM! WHOOSH! BOOM! And then—"
Arthur slapped a hand over her mouth.
"Stop narrating."
She giggled under his hand.
The elf father kneeled to Arthur's height.
"You have my eternal gratitude. If you ever need anything—food, shelter, training—our home is yours."
Arthur stiffened.
"T-that won't be necessary."
Emir's mother pinched his cheek.
"What a cute boy!"
Arthur swatted her hand away and took two steps back.
This family was more embarrassing than Alfred.
And that was saying something.
Once Emir was cleaned and fed, she dragged Arthur outside to the porch.
She held both his hands and announced proudly:
"I've made up my mind!"
"…That sounds dangerous."
"You're my BEST FRIEND!"
Arthur blinked.
"...Excuse me?"
Emir nodded with complete seriousness.
"Best. Friend. Forever."
"I decline."
"You can't decline! It's already decided!"
"That's not how decisions work!"
"It is! When it's destiny!"
Arthur stared at her as if she were contagious.
"Listen, Emir. I don't 'do' friends. Especially not clingy, loud, hyperactive, too-honest, sparkly-eyed elves."
"Awwww—you noticed all that about me?"
Arthur almost screamed internally.
"That wasn't praise!!"
Emir laughed.
"Too late! We're best friends now!"
Arthur groaned.
"Kill me."
While Arthur sulked, Emir plopped down in the grass and began plucking petals from a flower.
Arthur noticed something strange.
Every petal she touched shimmered with faint green light… then regrew instantly.
"…What are you doing?" Arthur asked.
"Playing!" Emir chirped. "Want to try?"
She plucked a flower and held it out.
Arthur examined the petals carefully.
That glow…
That regeneration…
That resonance with nature…
"Emir," he said slowly, "do you always make plants grow when you touch them?"
She blinked innocently.
"Mhm! Everyone says it's weird."
Arthur's eyes narrowed.
This wasn't normal elven magic.
This was ancient.
Sacred.
Extremely rare.
"Show me again," he whispered.
Emir touched a wilted leaf on a bush beside her.
It sprang back to life instantly, glowing softly.
Arthur's heart stopped.
"…Life Bloom Magic."
Emir tilted her head.
"Huh?"
Arthur grabbed her shoulders.
"Do you have any idea how powerful that is?!"
"No?"
"Idiot! That's one of the lost magic branches! Only extremely ancient elven royalty possessed—"
He stopped.
Emir didn't understand a single thing.
She just stared at him, smiling.
Arthur let go and leaned back.
"…Unbelievable. I'm surrounded by idiots with ridiculous talent."
"So… I'm talented?"
"That's not a compliment."
Emir giggled and poked his nose.
"I want to learn magic with you!"
"No."
"Why not?"
"Because you'll slow me down."
"Then you can teach me!"
"No."
"Pretty please?"
"No."
"With sparkles?"
"No."
"With sparkles AND puppy eyes?"
"…Stop. Don't look at me like that. I'm immune to this. I—"
He wasn't.
At all.
"Tch. Fine. Maybe."
"YAAY!!" Emir jumped and hugged him tightly.
Arthur sighed loudly.
He hated this.
He didn't hate this.
He was confused.
As Emir clung to him, telling him stories of her village, her dreams, her magic, and her favorite foods, Arthur found his guard slipping bit by bit.
When she rested her head on his shoulder, he went stone still.
She whispered:
"Arthur… I'm really glad you found me."
He turned away, cheeks burning.
"…You're welcome," he muttered.
Just loud enough for her to hear.
Later
Emir stood at the edge of Reed Village as Arthur turned to leave.
Her emerald eyes sparkled brightly.
"Goodbye, Arthur!! I'll see you again soon!!"
She waved both arms wildly like she was trying to cast a wind spell with enthusiasm alone.
Arthur raised an eyebrow.
"…Calm down before you take off like a bird."
"Nope! BYEEEEEEEE!"
He turned around and walked away while Emir continued flapping.
After a few steps, he muttered under his breath.
"What a weird, troublesome, overly sparkly elf."
But he kept walking.
And then—
"…She's definitely weird."
Another few steps.
"…Why did she smile like that? It's unsettling."
Another step.
"…No one should smile that much."
Another step.
"Why did she say she's glad I found her…? That's completely absurd."
Another.
And then without warning—
His cheeks warmed.
He slapped them with both hands.
"STOP. STOP THAT. NO BLUSHING. NONE."
He glared up at the sky.
"Stupid elf girl. Infecting my mind. Ridiculous."
A leaf drifted down and landed on his head.
"Even nature mocks me. Fantastic."
He sighed deeply and continued walking through the woods, grumbling:
"I saved her because those men were disgusting. Not because I cared. And definitely not because she's… cute or something."
He shook his head aggressively.
"No. No. Nope."
He kept walking, mumbling the entire way home—plotting strategies, thinking about new spells, imagining ways to blend in better while growing in power, and then—
Every few minutes, images of Emir holding his hand flashed into his brain, making him blush again.
"STOP THINKING ABOUT THAT."
A small woodland creature ran away in fear.
Arthur stepped onto the porch of his house.
He barely touched the doorknob when—
BOOM
The door exploded open as Elsa tackled him.
"ARTHURRR!! YOU'RE BACK!!!"
"Unhand me, woman!"
Anna wrapped around his waist like a koala.
"WE THOUGHT YOU GOT EATEN BY A WOLF!!"
Bliss simply appeared behind him like a silent assassin and tugged his sleeve.
"…You're late."
Arthur froze.
Her quiet tone.
Her soft eyes.
Ugh.
He looked away.
"I… got lost."
"No, you didn't," Bliss said bluntly.
"…I don't like how well you read me."
Elsa squeezed him tighter.
"We made snacks!!"
Anna added, "AND we saved you the biggest piece!"
Arthur raised an eyebrow.
"…Define 'biggest.'"
Anna proudly lifted a plate.
There was one crumb left.
Arthur sighed.
"Of course."
Alfred burst into the hallway with sparkling eyes.
"MY SONNN!!! MY BRAVE, WONDERFUL—"
Arthur instantly summoned a dark orb the size of a grape.
"Hades Sphere."
"WAIT—!!"
BOOOOOM
Alfred crashed through a wall into the living room.
Melda appeared from the kitchen carrying soup.
"Arthur, sweetie. No destroying your father before dinner."
Arthur clicked his tongue.
"Tch. Fine."
Elsa whispered to Anna, "He didn't say he wouldn't try AFTER dinner."
Anna nodded seriously.
Everyone gathered around the table.
Melda placed a giant pot of stew in the center.
Alfred limped into his seat, smoking lightly.
"Dinner time, family!"
"You're still alive?" Arthur asked, poking him with a spoon.
"Barely! But a father's love cannot be extinguished—"
Arthur quietly muttered a freezing spell.
Alfred's cup turned to ice.
"AH! MY TEA—!"
Melda sighed peacefully.
"This is nice. So calm."
Elsa: "Pass the bread!"
Anna: "STOP TAKING ALL THE CHEESE!!"
Bliss quietly cut vegetables for Arthur.
Arthur blinked.
"…What are you doing?"
Bliss shrugged.
"You like them this way."
Arthur's heart hiccupped.
He looked down.
"…Hmph. I suppose someone here is competent."
Elsa and Anna gasped loudly.
"DID HE JUST COMPLIMENT BLISS?!"
"No way!!"
Bliss's cheeks turned faintly pink.
Arthur immediately glared at his soup.
"Everyone shut up."
Alfred laughed weakly.
Melda giggled softly.
Dinner was pure chaos—food flying, Arthur dodging hugs, Alfred getting hit by random spells, Bliss staring fondly at Arthur while he pretended not to notice.
And yet—
Despite the chaos, the noise, the annoyance—
Arthur felt something warm inside his chest.
He hated to admit it.
But he also didn't want it to stop
Arthur finished his meal surrounded by noise, love, warmth, and insanity.
As he walked to his room, he murmured quietly to himself:
"…Tomorrow, I have to get stronger.
Break the seal.
Restore my father.
Fulfill my destiny."
He paused.
Then whispered even quieter—
"…But maybe I can… tolerate this… a little longer."
And in the corner of his mind, the memory of Emir's smile flickered again, making him blush before he punched his pillow aggressively.
"STUPID ELF GIRL."
