In conclusion, I failed.

I couldn't prevent another person from being reincarnated into Hart's body.

─ ─ ─ ─

I've always thought that since the Demon King reigned in this world, there would come another world who would be brave enough to defeat it.

Even as Hart celebrated his fifth birthday, he never turned into my brother. That's why I was a little relieved.

I didn't even hear anything about the demon king showing up somewhere in the first place. This must be between when your father took you to the king's capital, because he sneaked up on the voices of kings and ministers to check the situation in other countries as well.

I'm sure the Demon King couldn't emerge for any reason, so I thought the other worlds weren't reincarnated as brave men into the world over here.

But two days after Hart's birthday...

"Ah. Good morning... Dear Sister Charles (Hey)"

I was taking a break from my magic school class to come back to the mansion to celebrate Hart's birthday. So I was going back to school today, so I came to say goodbye......

Too much greeting.

Until yesterday, Hart had a different vibe.

I felt bad and tried to read Hart's mind.

... Oh, that?

Why is that?

The voice of Hart's heart was deafening.

For once, if it's just a little bit, I can hear my heart. I can't hear it as a voice well, kind of like a cover was put on Hart's mind.

I don't have a choice... let's do that.

Some humans rarely resist my reading minds. Tina, who became the exclusive maid of Hurt, is one of them.

Well, it's no wonder she says that about a hundred years ago now, she's a hero who worked with brave men from different worlds to defeat the Demon King.

But I had the means to even read the voice of such a hero's heart.

That 's--

"Hart, hi."

I hugged Hart and turned my hand around his neck, touching his skin directly.

Being in direct contact with the subject - this is my strongest reading mindset, where even the voice of a hero's heart can be heard.

It's usually the ability to listen to a human heart nearby, but when his skin is in direct contact with someone, he can only hear that human heart.

And it doesn't make sense that the subject was taking measures to prevent thoughts from being read with any powerful magic or magic.

Once upon a time, when your father introduced Tina to our family, she didn't say it in her mouth, but she leaked it with her heart about her level.

Tina's level is 250. Sounds like a profession called Magic Swordsman. I think he's the strongest man in this world right now, without the brave man.

Besides, Tina is an elf with strong resistance to mental attacks.

Elves and the strongest being in the world. Even Tina-Harribel's voice could be heard if he could touch his body, and Hart's voice could be heard because I used my skills to the best of my ability.

"Wow. Shah, Sister Char (hey)!?"

(Oh, sister...... skinship, isn't it intense!?)

The voice of my heart didn't belong to Hart.

Because Hart has never called me 'sister'.

... really, it looks like the otherworlds have gotten into Hurt's body.

It got dark in front of me.

My sweet Hurt. My brother, who sounded so beautiful...

He's gone.

What shall we do......

How can we get Hart back?

…………

"Oh, um... what's going on?

(Why won't you leave me? But it smells so good, I guess I can keep doing this for a little longer)

I haven't changed the type of detergent that washes my clothes since Hart used to tell me he liked the smell of my clothes.

At the Count Silveray house, the whole family is having their maids wash their laundry separately with different detergents.

It can be to prevent clothes from being taken apart. By the way, among the Count Class nobles, it's very normal.

"Hey, Hart."

"Yes, sir"

"The smell of my clothes, like it?

"I love it!

(I haven't smelled much in the original world, but why... I like this smell)

He doesn't seem to know very well himself, but his tastes haven't changed with those of Hurt.

Though the singular name of the voice of my heart has changed to 'me', I was convinced that there was a Hurt in Hurt's body.

Your father also said, 'Because the souls of Hart and those of the other worlds mix, they do not cease to be completely harts' ─.

That's why Hart is here.

I was a little relieved to find that out, but I had another thing I really needed to check on.

"It's me, I'm going back to magic school for lunch. So long time no see...... bathe with me, won't you?

What I wanted to make sure was that the otherworlds who have been reincarnated into Hart's body are not sketchy Osama.

Even though my pretty little brother's soul is here, if it was Osama mixed up with it...... something, I don't like it.

If it were (...) or (...), I might try to get rid of Osama's soul from Hart at any cost.

That's why I tried Hart.

"Oh, is that a bath?!?"

(No, I'm five now... that's just not good. I remember taking a bath with your sister, but...)

Hart's lit up.

The voice of my heart was in quite a hurry.

Something like that at the beginning.

I mixed it up with Hart's soul, so I thought it was, but are the otherworlds who have been reincarnated young for what?

I was a little horrified.

I'm glad they didn't give me an instant answer for wanting to take a bath with me.

"Hehe. I'm just kidding."

"... already. Don't make fun of me."

(Your sister is so cute, I can't turn her down if she asks me out so hard?)

Not as beautiful as the original Hurt, but his heart's voice sounds so beautiful and well.

I found out that it must be the good guys who have been reincarnated.

And I guess it's also a plus point that you said I was cute.

─ And I flashed that it was here.

"Hart, do you have a minute?

"What is it?

"When Hart grows..."

Hurt is Hurt, but it's not entirely my brother Hurt anymore.

Then I love Hurt.

So...

"Marry me!!"

The otherworlds have been reincarnated, and they're not full sisters and brothers anymore.

There's nothing wrong with getting married in the future, is there?
