I Became the Twin Sister of the World’s Strongest Person (1)
A strikingly handsome man with pitch-black hair darker than night and golden eyes brighter than pure gold opened his mouth.
“Is it not enough?”
“…Pardon?”
“I asked if it is insufficient.”
Across from the man’s seat sat a ten-year-old girl with the same black hair and golden eyes.
The girl, Sanael, broke into a cold sweat and trailed off.
“Well….”
The table was filled with everything the girl loved.
Chocolate cake, fondant au chocolat, chocolate macarons, chocolate fondue, fresh fruits coated in chocolate, and more.
It’s more than enough! There’s so much I’ll burst from eating it!
She screamed internally, but thanks to years of social experience, she managed to keep a smile.
“Haha… i-it looks delicious.”
“Are you not going to eat it?”
“I-I will! Haha….”
With trembling hands, she picked up a fork—when suddenly, all the desserts on the table were pushed aside.
“Huh?”
And then, onto the cleared table, a gigantic whipped cream cake slammed down with a thud.
“Big sister! Forget cheap snacks like this—eat this instead!”
What appeared was a beautiful girl with honey-colored hair and pinkish eyes, holding an eight-story-tall giant cream cake.
“Raphael?”
“Here, Sanael unnie. Ahh!”
Raphael scooped a piece of the cake with a fork and shoved it toward Sanael’s mouth.
Sanael had absolutely no desire to eat cake, but unable to refuse her adorable younger sister, she ended up taking a bite.
“How is it?”
“Uh… i-it’s good.”
“Isn’t it better because I fed it to you?”
Then a blunt voice came from across the table.
“That child prefers chocolate over cream. Did you really think she’d like something just because it’s absurdly large? Such childish thinking.”
“Hmph. Do you really think my sister would be satisfied with something like that cake? And chocolate is so outdated. You don’t even know her taste.”
Raphael smirked, and the man’s eye twitched.
“You also prefer that ridiculous cake? Sanael.”
“Pardon?”
“Big sister, you like my cake, right? Right?”
Before Sanael could answer, the two began bickering.
“I prepared chocolate desserts. And that whipped cream cake. Choose one.”
“Why even ask? She’s obviously going to say she likes mine.”
“Don’t be ridiculous, brat.”
“Stay out of this, old man.”
“…Old man?”
The man glared fiercely at Raphael. Raphael stood up abruptly and scoffed.
“You want to fight?”
“Good. Let’s see if that tiny mana of yours has improved even a little.”
Mana gathered in both of their hands.
It turned into blazing fire, then freezing ice.
KWA-GA-GA-GANG!
Magic was unleashed at each other in an instant.
“W-wait a second!”
If you two start fighting like this, what am I supposed to do!?
Originally, the two were supposed to be a loving father and daughter who adored each other.
…At least, that was how it was in the novel Sanael had read in her previous life: “The Lonely Princess of the Ice Kingdom.”
KWA-AA-AAANG!
“Stop it! Both of you, stop fighting!”
But—
Ever since Sanael got between them, something had clearly gone wrong.
How did a doting father and daughter turn into mortal enemies?!
She looked at the ruined garden, tears welling up.
The last thing she remembered was a yellow sports car.
Blinding headlights rushed straight toward her, and a sharp pain followed.
Then she opened her eyes.
“Waaahhh!”
And she had become a baby.
“Oh my! Princess Sanael!”
“The princess has finally started crying!”
Three servants rushed around in panic as she cried.
“This is impossible! She has never cried since birth!”
“Call a healer! Immediately! There might be something wrong!”
Why was everyone making such a fuss over just crying?
As Sanael wondered this, she was lifted into someone’s arms.
A young woman with beautiful green eyes—the nanny—held her gently.
“There, there. Stop crying. I’ll help you.”
…Warm. It feels like mom.
She hadn’t seen that face in over ten years, but the sudden wave of longing made her cry even harder.
While she was still sobbing, another cry echoed nearby.
“Uwaaah….”
“Oh! Princess Raphael has woken up too!”
Rapha…el?
That name sounded familiar.
“She woke up because she wanted to play with her sister Sanael, didn’t she? As expected of twins.”
Sanael slowly turned her head toward the sound.
There she was.
A ridiculously cute baby with sparkling eyes.
Honey-colored wavy hair like golden wheat fields in autumn.
And pink jewel-like eyes resembling spring blossoms.
A beauty so overwhelming that anyone would gasp.
No way.
Sanael already knew who she was.
Sanael came to a conclusion.
This is the world of “The Lonely Princess of the Ice Kingdom.”
And she had reincarnated into it as a modern person.
More specifically, she was the twin sister of the female protagonist, Raphael de Skadi.
“Sanael… that name doesn’t even exist in the novel?”
As a devoted reader who had memorized the original story, she was certain.
There was no mention of the heroine having a twin sister!
Had the story changed because of her reincarnation?
While she was lost in thought—
“Ugh…!”
A sharp pain came from her finger as she struggled.
Let go! You’re going to break my finger!
Raphael, the heroine, was holding onto her finger tightly and refusing to let go.
“Fufu, such beautiful sisters.”
“For the Skadi Magic Kingdom, this is truly a blessing. It must be the blessing of the twin moons.”
Someone save my finger! Stop smiling like proud parents!
The nanny and servants ignored her suffering, smiling warmly instead.
“If only Her Majesty the Queen could see this…”
“Shh. Don’t say more.”
The Queen—the mother of both Raphael and Sanael—was already deceased.
“…Never speak of the late Queen carelessly. If you want to stay in the palace, be careful with your words.”
“Y-yes!”
As expected, she was already gone, just like in the novel.
So she died without even seeing her daughters…
Sanael felt a strange emptiness.
Then she looked at Raphael, still holding her finger.
“Uuu! Uuuung!”
Raphael babbled excitedly, but Sanael couldn’t understand a word.
I’m sorry, but I have no idea what you’re saying.
While everyone admired the “blessed twins,” Sanael noticed something else.
The castle they were in was in terrible condition.
Broken windows, crumbling walls, dusty furniture—or rather, almost no furniture at all.
This is worse than I remember from the novel.
Their father, King Grandeel de Skadi, had never issued any orders regarding them.
The queen had died after childbirth, and the king had gone off to war.
Because of his indifference, the palace officials neglected the twins entirely.
Raphael was left in a run-down palace called “Dahlia Palace,” barely surviving with only a nanny and two servants.
And now I’m here too.
Before she could fully process it—
BOOM!
“Aaaah!”
An explosion shattered the wall.
“By the cursed twins of the king! We will take your lives!”
Assassins.
Just as she remembered from the beginning of the novel.
A blade dripping with poison approached her face.
Too late to escape.
No way… I die like this?!
Clench.
A small hand grabbed her wrist.
When she turned her head—
Raphael was laughing brightly.
…She’s laughing at a time like this?
And then—
KWA-AA-AAANG!
“Gahhh!”
The assassin was slammed into the wall.
