My Fiancé Fell in Love with My Older Sister. After Locking Myself in My Room for Five Days, 500 Years Had Passed. - 42 - About the Dark Magic Used by the Royal Family of the Lumos Empire

According to the map that the civil officer showed me, I thought it was about as far as Tokyo to Niigata…!?

Prince Lian looked very pleased as he spoke to surprised me.

“There’s a trick to it. Don’t worry, we’ll return within the day. After all, it’s just a walk.”

…Apparently, Prince Lian’s idea of a walk covers a very large area.

When I got into the carriage, he sat across from me.
Once the door was closed, Prince Lian started chanting something like a spell.

“…”

In the next moment, a staff appeared in his hand.

(So this is the Five Elemental Magic…)

As I stared in amazement, Prince Lian began to explain.

“This is dark-element magic.”

“Dark!?!?”

Not the Five Elemental Magic!?

Seeing how wide-eyed I was, he laughed.

Like a child who had pulled off a good prank, his eyes sparkled mischievously.

“Were you surprised?”

“I… I was surprised!! I haven’t even seen the Five Elemental Magic yet…!”

“Ah, right.”

“Yes, that’s right!!”

Then, Prince Lian tapped the carriage floor with his staff.

“─”

The next moment—

The carriage shook violently… or at least, it felt like that.

Rather than strong shaking, it felt more like a dizzying spin.

However, my body didn’t sway, so it wasn’t actual dizziness or the carriage shaking…?

Unable to grasp what just happened, I looked up.

Prince Lian still had his staff touching the floor, both hands resting on its handle.

A faint light glowed below it, forming what looked like a magic circle.

(So this is dark magic─)

Not knowing what effect it might have, I instinctively tensed up.
Then Prince Lian calmly began to speak.

“As I mentioned earlier, if we went from the Lumos Empire’s castle to the Tower of Lament by normal means, it would take more than a week one way. That’s why we’re simplifying the process like this.”

I took my time to organize his words in my head.

And then, I arrived at one conclusion.

“…So, this is some kind of teleportation magic?”

But Prince Lian answered, “No.”

(It’s not!?)

“This is a state where we’ve temporarily erased our coordinates from the real world. It’s similar in principle to time-crossing magic.”

He casually said something outrageous.

“Originally, dark magic was violent magic used to attack enemies. After the war ended, we no longer needed to use it to defeat enemies. But I’ve been thinking for a long time if it could be used in a more practical way.”

Then, Prince Lian looked up and gave a gentle smile. His long blond hair swayed lightly at his chest.

“The ability of dark magic is to allow attacks from the void. This time, we’re using that in reverse—to let us slip into the void.”

“…!?”

At his explanation, I felt my back go completely straight.

(So… that means…??)

I still don’t really understand what dark magic or light magic actually is─

But I’ve heard that only the royal family of the Lumos Empire can use either of them.

And as for the nature of dark magic, Prince Lian just explained it to me.

I slowly processed his words and tried to figure out our situation.

(So… what does that mean?)

Right now, we’re─

“We’re not in the real world!?”

With a loud thump, I stood up in shock.

Prince Lian gave a troubled smile at my reaction.

“That’s correct. But don’t worry. We’re set to arrive at the designated coordinates in about an hour.”

“─!!”

I was so shocked, I couldn’t even speak.

(Right now, we’re not in the real world. And we’re inside the void… which means─)

That means there’s a huge chance we could just disappear completely……!!!!

My vision spun again.

Prince Lian still held the staff firmly, his expression a little apologetic.

“I’m sorry I explained it so late.”

With a stiff smile, I answered, “No… it’s fine,” my voice completely lifeless.

Judging from how he’s still touching the staff, something terrible would probably happen if he let go.

That’s how tense, panicked, and confused I was—enough to mutter words from my past life.

It felt like I’d unknowingly gotten on a rollercoaster with no stops allowed.

(Wh-what the heck is with this man!!)

Everything he does is just too crazy!!

So this is what the Lumos royal family is like…!!

Even His Majesty called for that audience so suddenly…!

(It’s the bl00d…!! This must be the bl00d of the Lumos Empire’s royal family…!!)
