Mayuten ~The Demon King and the Hero Reincarnated as Twin Elementary School Students~

Chapter 3 The Hero Laments

Struggling and screaming, Isumi, also known as Shirene.

“W-What are you doing?! Stop!”

Dr. Naruse restrained Isumi’s hands and feet with cloth strings, tying them to the bed rail.

Well, it can’t be helped. She’s an injured person in a state of confusion, resisting treatment and causing a commotion.

The needle for the so-called “IV” was inserted back into Isumi’s right arm.

Despite Isumi still protesting, claiming she’s a hero, the adults seemed to be ignoring her.

Dr. Naruse said, “I have other patients to attend to,” and left the room for a moment.

Isumi’s mother followed, taking Hikari with her.

Father remained, looking puzzled as he dealt with Isumi’s struggles.

I guess I’ll have to do something about this.

I’ll talk to Isumi… no, Hero Shirene, using the language of our world, not of this one.

“Calm down, Shirene.”

In response to my words, she glared back sharply and shouted, “You! Send me back to my original world!”

Well, even if she says that…

I don’t know how to send her back, and honestly, it’s probably impossible.

“I said calm down. Your parents must be worried.”

“I don’t have parents!”

“Is that so?”

“My parents were killed by you demons when I was just a baby!”

I see. Her hatred towards demons and the Demon Lord might be related to her parents’ tragic fate.

“I apologize for that.”

“You think a mere apology will make me forgive you!?”

“I don’t expect you to forgive me. Just like how I can’t forgive the former human king who deceived and killed my parents.”

My parents—the former Demon Lord and his wife—went alone to the human kingdom for peace negotiations. They offered the Demon Lord’s wife as a hostage for the sake of peace.

My father agonized over it, but he accepted the condition to avoid war.

But it was a trap.

The humans treacherously held a blade to my mother’s throat, killed my defenseless father, and then took my mother’s life too.

With the path to peace closed, I ascended as the new Demon Lord and led the war against the humans.

“You speak nonsense! Do you dare insult His Majesty, the former king, who risked his life to defeat the Demon Lord!”

The righteousness of the brave hero is truly unshakable.

In that case, I’ll try a different approach to persuade her.

“Regardless, we have been reincarnated as twins in this world. We should try to get along.”

“Don’t mock me!”

“Then shall we fight each other again here?”

“Fine! I accept your challenge!”

Oh, dear. It’s just exasperating.

What meaning is there in fighting each other now?

I sighed and spoke to the brave hero.

“But if we do that, we’ll only bring sadness to the parents and sister of this world.”

“What?”

“You should pay attention. The man over there is the father of Kageyo and Isumi. The woman earlier is their mother, and the young girl is their sister, right? If we fight and hurt each other, we will make these unsuspecting parents and sister in this world cry. Is that what you want?”

“Hmm.”

My words silenced her as well.

“What should we do?”

As she asked, I could see her kindness shining through.

“There’s no way I could make innocent children or parents cry.”

I nodded.

“Alright, then… For now, let’s agree to a temporary truce.”

“I appreciate that.”

“But remember this! I will never forgive the Demon Lord. Someday, I will definitely kill you!”

She shed tears and pounded her bound left hand against the wall in frustration.

“Darn it, darn it, darn it! I can’t do anything even though the Demon Lord is right in front of me!”

Her father, taken aback, tried to restrain her left arm.

“Isumi! What happened to you? And Kageyo, you’ve been speaking words I’ve never heard before!”

I see. I must have worried her father too with my unfamiliar language.

Not using the language of this world, Japanese, I apologized to him.

“I’m sorry, Father. Let’s calm down, Isumi,”

Shirene, or rather Isumi, clicked her tongue and still apologized to her father in the language of this world.

“I apologize, Father. I won’t cause any more trouble.”

Indeed, Shirene, the Hero, has a gentle heart.

Her father chuckled.

“Hahaha, if Kageyo calls me ‘Father,’ then Isumi calls me ‘Father,’ huh? Both of you have changed your way of speaking quite a bit after the accident.”

Yes, I want to learn more about this world, but it seems even more important to find out about ‘Kageyo’ and ‘Isumi,’ the names we have now.

I made a mental note of that while gazing up at the ceiling.

There, a bright source of light, different from the flames or the magic of illumination, was shining.

I would soon come to know it as a ‘fluorescent lamp,’ but that was a tale for another time.
