My sister is a monster fascinated by the power of magic.

A twin sister who split blood.

A family that has grown up together under her mother.

I have the opposite personality, my hair color is black, and my sister is white. Everything was the opposite, but I thought it was strange and friendly...

We are neither humans nor monsters, nor beasts, but we have one end of the monster's power and are therefore susceptible to its instincts. Because of this, the people in the nearby village were spooked, and sometimes they continued to scold and mock at each other.

It was my mother and sister who protected me.

That's why it wasn't hard for me.

With your mother, you can overcome a difficult life and a difficult situation with your sister.

--Yes, I believed it.

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

One day, all of a sudden, my sister changed.

The villagers who mocked and looked down on us as “mixtures" and “monsters” and the sister who destroyed the house, without even hearing the voice of my mother and my stopping voice, wrapped up their power as monsters, and said so to me, and disappeared.

Afterwards, an organization called the Demon King Army came up with stories of sisters and sympathetic people leading monsters and doing bad things.

---This is the play my sister was talking about.

My sister, who had become a leopard, was swallowed by the power of the monster.

A lot of people have been hurt because of this.

As soon as I was gone, I left my mother and tried to find my sister.

To do this, I had to acquire the power to fight, and I needed a technique to know my sister's information, but neither of them was equipped for me.

I was good at handling knives.

My strength as a monster has grown my body strong.

However, on the other hand, when it comes to fighting, I will be swallowed up by my power as a monster, and I will fight roughly so that I can become violent.

----I don't want to be like my sister....!

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

But to get close to your sister, you need to learn to handle your powers.

Being impatient and always in anger with myself - I was summoned to the Kingdom of Hendir as a brave man in a brave summoning ceremony.

A special Transfer Magic Faction in the Hendir Kingdom, limited to the realm of the Kingdom.

As a result, I was summoned by the Queen Jessica Flair Hendir to take on a mission as a brave man.

The brave man was in a convenient position to approach his sister in a way, but I was not overwhelmingly strong enough to be a brave man.

Explaining it to the queen, she smiled refreshingly, not seemingly a queen -

Then hurry up and strengthen yourself. Besides, you have lonely eyes, so find a “companion” you can trust from your heart. Let's start there. "

I was surprised at the way it was said that it was too crushed.

Something like that made me unpublished as a brave man until I gained strength.

Honestly, just because you've become a brave man doesn't mean you've changed your position and become stronger. There was a plan to train the Knights of the Kingdom, but since my way of fighting in the first place was a world-class one far from the Knights of the Kingdom, I didn't get much fruit.

At that time.

I heard about the brave man who was summoned to the Kingdom of Filgen at about the same time as me.

Although his name has not been announced, he is a special brave man who has been summoned from another world.

In an unprecedented state of affairs, the Hendir Kingdom side was also confused, but when I heard that the hero had grown strangely in less than a few days since being summoned, the surprise turned into something else.

---The genius of the heroes of other worlds is too abnormal.

That was my impression of those who knew about the brave.

Still surprising, but even more surprising was the “request to search for someone” from the Kingdom of Filgen.

It was about the boy who got caught up in the summons of the warriors of the different worlds of the Kingdom of Filgen.

His name is Alihara Kite.

They were interested not only in the Queen, but also in other kingdoms.

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

In other words, the talent of the person cannot be the same.

Quickly, the chosen brave men and the bounty hunters searched for him.

Well, as I searched for a trusted companion, I went to the guild where the Queen gave me permission and all the talented people ---,

Kite.

While I was walking around the guild doing nothing, I heard a voice like that.

Reacting to the voice, the Lord of Voices was a black cat on the table.

In front of the black cat was a boy stroking a silver slime---and the moment I saw him, my strength as a monster in my chest stopped snugly.

---That was the meeting with Kite.

At first, Jacob Rising was given a pseudonym or something really confusing... Ever since then, his presence has been out of my mind.

It was my first experience to be able to suppress my powers as a monster, and above all, he was nostalgic for two characteristic monsters and accepted it because he was a favorite person for me with powers as a monster.

So when we met again in the room where the Adventurer took the exam, I felt like I wasn't cool.

Then I found out that he used a pseudonym against me, and that his own magic had a special magic called "Pure Demon Magic”, which could calm my power as a monster.

His power was fascinating, but I was honestly glad he could help me.

I was so relieved to be able to fight together that I was able to understand that this was the queen's “trusted companion".

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

But for now, I'm going to fight with Kite.

We do our best to make requests, and we get stronger together.

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