I Became the Twin Sister of the World’s Strongest Person (3)
Sanael grabbed her aching forehead and let out a small tear.
I finally managed to walk before Raphael… and this is cheating!
Raphael, true to her “world’s strongest mage” setting, had already learned a high-level wind magic—Wind Surfing—without anyone teaching her.
On the other hand, Sanael was a powerless normal human. A Publico.
After her diagnosis, Kanna repeatedly asked Aira to recheck Sanael’s mana, but Aira only shook her head with a troubled expression.
For Sanael, who now had to survive a second life inside this harsh novel world, it was shocking—but since she had originally lived in a world without magic, she adapted surprisingly quickly.
Actually, not having mana might mean fewer life-threatening situations. These days, assassins are targeting Raphael first anyway.
But still—
…I’m jealous. Magic.
That feeling was unavoidable.
“Zzz… zzz…”
While Raphael slept, Sanael got up quietly.
Looking around, the servants had all left on patrol.
Now.
She carefully climbed down and crawled under the bed.
There, she found a small booklet tucked into the frame.
“Dragon Knight of the Continent, Tale of Kalmen”
A thin children’s picture book small enough for a baby to hold.
When Sanael opened it, faded illustrations appeared along with messy handwritten Korean text.
- Raphael 3rd: minor dispute with servants over meal menu. Probably summer.
- Raphael 5th: first encounter with Grandeel, but he ignored her and walked away. Ended anticlimactically.
- Raphael 10th: main story begins. Key characters appearing that day include Kaidia, Randolph…
It was all notes Sanael had written from the original novel.
Recently, once her hands became strong enough, she secretly obtained charcoal and began recording everything.
I need the novel’s settings and events to survive.
Whenever Raphael and the servants were distracted, she used that time.
While carefully writing line by line—
“Uuuung…”
“!”
At Raphael’s whimper, Sanael startled and stood up quickly.
Rustle!
“No!”
The book slipped from her hands, scattering pages across the floor.
Because the book was old, even a small impact broke the binding.
Sanael quickly crawled and gathered the pages—but one was missing.
“W-where is it?”
She searched frantically until her eyes locked onto the bathroom door gap.
A thin sliver of space where wind leaked through.
Don’t tell me it went in there…?
Sweat dripped down her forehead.
That’s outside the barrier…
Leaving the barrier meant stepping into potential assassin territory.
But losing that page was worse.
If the servants found out a baby could write unknown symbols, it would cause problems.
Just for a moment… it should be fine.
She nodded and stretched upward, barely reaching the doorknob.
Click— the door opened.
“…Found it!”
The missing page lay alone on the bathroom floor.
Sanael sighed in relief, grabbed it, and turned to leave—
“That’s lucky.”
A voice spoke.
Sanael froze and turned around.
A masked man stood there.
“…An assassin!”
She noticed the broken window latch.
She had been careless.
“Kids shouldn’t wander alone at night, heh.”
The man drew a sharp needle.
At that moment—
“Hmm… Onni…?”
Raphael floated near the bathroom entrance, rubbing her sleepy eyes.
“…Pink hair? Then that must be the monster princess.”
The assassin immediately changed targets.
“Sanael!”
Sanael shouted—
“Raphael!”
But Raphael only turned slowly, still half-asleep.
Not now…!
She recalled the setting.
Raphael’s weakness: severe sleep inertia.
And she could only use magic consciously.
Swish!
The weapon flew toward Raphael.
“No!”
Sanael ran—
But she was only a toddler.
I can’t let her die like this…!
Raphael de Skadi.
She had once been just her favorite character.
But now—
She was her sister.
Her only sister for over a year.
“Raphael!”
She screamed—
And then—
The weapon stopped.
“…!”
The assassin froze completely.
Raphael also stopped moving.
It was as if time itself had stopped.
Only Sanael could move.
What… is this?
Suddenly, light poured in.
From the ground, light rose and formed a human shape.
White hair like snow.
Eyes black as ink.
A tall man in a white robe stood there, glowing as if detached from reality.
[…Do you wish to save that child?]
His voice echoed through the frozen world.
Sanael wanted to speak—but couldn’t.
She managed a small nod.
The man raised his hands.
Dark energy formed.
It twisted like smoke, then condensed like liquid.
It changed shape endlessly.
Then it moved toward the assassin.
The darkness swallowed him whole.
“…!”
The black mass shrank, like something devouring him piece by piece.
In moments, it vanished completely.
The assassin was gone—no trace left behind.
“…What happened to him?”
Sanael forced out the words.
[He was sent far away. Somewhere he cannot reach you.]
A gentle voice.
Their eyes met—black and gold.
“…Who are you?”
The man only smiled softly.
[There is no time left.]
He turned away and began to leave.
His body dissolved into light.
Sanael grabbed his robe.
“Wait!”
The man turned in surprise.
“You are Shade, the Spirit King of Darkness… aren’t you?”
He did not answer.
Sanael swallowed hard.
“Why are you with Raphael…?”
But she couldn’t finish.
The man gently placed a hand on her head.
[Please take care of yourself.]
And then he vanished completely.
Time resumed.
Raphael blinked.
“Uu…?”
She looked around, still confused.
Sanael exhaled deeply.
What is happening…?
A cold wind swept across a barren land.
Once a thriving city—now nothing but ash and ruins.
A woman walked alone across the empty ground.
She spoke.
“Are you there? Shade.”
A man appeared behind her.
White robe. White hair.
He bowed his head.
“…I always regret.”
“Please do not say such things.”
“You’re the only one who says that.”
They walked together across the wasteland.
“Sometimes I think…”
“What do you mean?”
“The hero on a white horse.”
The man paused.
“A fairy tale hero?”
“Yes. Someone who saves everyone without hesitation.”
The man said firmly:
“That was you.”
“…I wish I had someone like that too.”
She looked up at the sky and smiled faintly.
“I wish it existed.”
The wind was cold.
And the world remained silent.
