My sister - my sister is a monster who has been fascinated by the power of demons.

The twin sisters who divided the blood.

The family we've grown up with at Mother's.

My personality is the exact opposite, my hair color is black and my sister is white. Though everything was the opposite, he thinks he was close to wonder...

We who are neither human nor demonic, nor beastly men, have one end of demonic power but are therefore susceptible to being pulled by that instinct. Because of this, people in nearby villages kept saying spooky, occasionally heartless curses and words of ridicule.

It was my mother and my sister who protected me like that.

So I couldn't be harder.

A hard life, a situation, if it's your mother's, with your sister, you can get over it.

- Yes, I believed you.

"---Leafa, let's play. Me and you, as usual. '

One day suddenly, my sister changed.

Without even hearing the voice of my mother and my restraint, the people of the village who had mocked us as "mixed things", “monsters” and looked down, and their sister, who had destroyed the house, wrapped her powers as a demon around herself, saying so to me, and disappeared.

Then there was an organization called the Demon King Army that had a story about a sister and a thoughtful person leading a demon to do something wrong.

- This is the play your sister was talking about.

The leopard-changing sister has been swallowed up by the power of demons.

A lot of people are hurt because of that.

Being unable to stay or not, I tried to find my sister as soon as I left her.

In order to do so, I had to acquire the power to fight, and I needed the skill of being able to know my sister's information, neither of which was available to me.

I was good with knives.

Power as a demon was making my body grow strong.

But on the other hand, when it comes to fighting, I'm swallowed up by my powers as a demon, and, as I ramble, I'm going to fight rough.

- Like your sister, I don't want to be...!

I don't want to be swallowed up by the power of demons.

But you have to acquire the art of dealing with your own powers to get close to your sister.

In my impatience and constant anger towards myself - I have been summoned by the Kingdom of Hendil as a brave man in the ritual of summoning brave men.

A special transfer magic formation that takes place in the Kingdom of Hendil and is limited within the realm of the Kingdom.

As a result, having been summoned, I was to receive a mission as a brave man by the Queen - Dear Jessica Flair Hendil.

The brave man was in a position of convenience in a way to approach his sister, but I had so much qualities as a brave man that I was not overwhelmingly accompanied by strength.

Explaining that to the Queen, she has a refreshing grin that she doesn't think is the Queen -,

'Then get on with your strength. And you, you've got lonely eyes, so find a "companion” you can trust with your heart. Let's start there.'

I was surprised not to think of the way I said it so shattered.

That being the case, I was not to be published as a brave man until I gained strength.

Honestly, just because you've become a brave man doesn't mean you've just changed your position and made yourself stronger. There was also a proposal to train kingdom knights, but my way of fighting in the first place did not yield much aromatic results because it belonged to our own people, far from kingdom knights as well.

That's when.

It was about the brave men summoned by the Kingdom of Firgen at about the same time as I did.

The man is a special brave man whose name has not been made public, but has been summoned from another world.

Unprecedented events also had confusion on the part of the Kingdom of Hendil, but the surprise turned to something else when he heard that the brave man was being summoned to show unusual growth in less than a few days.

- The talent of the brave men of different worlds is too unusual.

That was my impression with those who found out about the brave.

Still, surprisingly, it was the "search request for a certain person" sent by the Kingdom of Firgen that was more surprising.

What a thing that was about a boy caught up in the summons of the brave men of the other worlds of the kingdom of Filgen.

His name is Alihara Kite.

He said that people from other kingdoms as well as the Queen were interested in this.

of the same world as a brave man of unusual talent.

For the talent of the person cannot be lined up either.

Quickly, those who had already been chosen as brave men and those who were looking for bounty money were going to look around for him.

Well, nothing else. I also went to the guild to get permission from the Queen and have all the strength, looking for it with the feeling that I would look for it at the end of a trusted fellowship----,

"Kite."

I heard such a voice as I looked around the guild at all costs.

If you react to that voice, the Lord of the Voice was the black cat on the table.

In front of that black cat there was a boy stroking a silver slime--the moment I saw him, his power as a demon that had been bothering me in my chest had stopped perfectly.

- That was the meeting with Kate.

At first they named Jacob Rising an alias or did something so confusing...... Ever since then, his presence has been out of my mind.

It was my first experience that my power as a demon could be suppressed, and above all because he was nostalgic for two characteristic demons, and accepting it, he was also a favored figure for me with his power as a demon.

So when I reunited in the room taking the adventurer's exam, I didn't feel calm, not even in the pattern.

Then I also found out that he used a pseudonym against me, or that his own magic powers possess a special magic called "pure demon magic" that can calm my powers as a demon.

His power is fascinating, but more than that, I was honestly glad he helped me.

I was so relieved to be able to fight together that I could understand that this was the Queen's "trustworthy companion from the heart”.

Until now, I've been thinking about stopping my sister all by myself.

But now, I fight with Kite.

I'll do my best to do the request, and we'll be strong together.

Not for the brave of the kingdom of Filgen, but for him who chose me.
