The wyvern Lisa and I were riding on descended in a slow circle.
The sound of the wind was clamorous in our ears.
Finally we landed on the ground and jumped.
A jet-black castle stands in front of us.
The place where we find ourselves is the garden of the royal castle where the demon king lives.
The black wyvern I rode on curled up and began to sleep.
"I expected the demon king's castle to be creepier... But it's pretty standard."
"Who would like to live in a horrible place? A strong beast can only grow in a suitable environment, remember that a scrawny tiger will lose to a well-fed wolf."
I see, that's true too.
Even the demon race does not want to live in a difficult environment.
"Based on what we talked about on the way over, are you sure about all this?"
"Of course. You must be my servant, the hero meant to be the champion of the world beyond the demon king's lands."
"Then speak with more humility. I am offended by your attitude."
"Oh, I'm sorry. It's not that I want to look like a fool, it's just that I'm trying to project my dignity as Demon King."
Lisa hugs me and apologizes.
I'm turned on by her breasts pressing against me and the cleavage peeking out from so close.
She also wraps her long, white leg around mine.
She is the Demon King, and she is terrifyingly beautiful and bewitching, and she stimulates me to the extreme.
"I will give you everything I have."
"I'm counting on you, Lisa."
I remembered the moment Toru showed up, he was very upset.
I never thought that Toru, that fucking loser, would turn out to be the hero of the Manyu Brigade.
I'm curious to know how he got so much power, but he's no match for me anyway.
I have a level 800 demon king by my side.
In addition, she says that it is possible to greatly increase my power with her side's demonic elements.
I've been exercising steadily, and it's getting ridiculous.
"Come this way."
While Lisa guides me, I enter the castle.
"Welcome, demon king."
It was the maids who greeted me at the entrance.
All of them are beautiful and to my liking.
I have always wanted to hold a demon woman in my arms.
"You are free to do whatever you want. This is your castle."
"Kuku, that's great, is there anything else I should know about?"
I walked up the stairs and into the courtroom.
There stood a black throne decorated with gold. A ruler's chair which is perfect for me.
Lisa insisted that I sit down.
It feels good.
Kings live well.
Kata kata kata kata
The sacred sword at my waist begins to tremble.
The next moment, the sword disappeared in a burst of light particles.
"Where did the sacred sword go!!!?"
"You are no longer worthy. But don't worry, here is a demon sword that is as good as the holy sword."
"I hope so."
It's true that I lost the sacred sword, but that doesn't mean I'm in trouble.
If there is a replacement for that weapon I will gladly use it.
Besides, I've always been more interested in demonic swords than sacred ones.
Those monstrous designs are my favorite.
A beautiful black-haired woman enters the room.
Deneb must be one of the six generals.
She was dressed in a tight black suit, and her arms were covered with hand armor that looked like demonic armor.
I couldn't help but lick my lips at the sight of her style.
Deneb keeps her face down and her gaze fixed.
I don't dislike her strong attitude.
It makes me feel better when they look at me from the ground.
"Prepare a demon sword for Sain."
"I will do so Immediately."
Deneb, who left the room, immediately brought a sword.
It is a jet-black, one-handed sword of hideous and terrifying design.
Even just looking at it gives me chills.
"You can't use a sacred sword unless you take it off its pedestal, but a demonic sword is different. Anyone can use it and become its owner."
"What happens if the owner dies?"
"It comes back here. It's the same as the sacred sword in that regard."
I rose from my throne and picked up my demon sword.
I grabbed the hilt and tried to pull it out of the holster, but quickly stopped myself.
The sacred sword has had its trials. It is normal to think that the demonic sword also has them.
Lisa knew what I was thinking, so she gave me a brief explanation.
"There is only one test for the demon sword. It is to draw the sword from its sheath. However, a pain more terrible than death will try to prevent you from doing so."
"I just have to take it out? It's easy."
I began to draw the sword quickly.
I immediately felt a tremendous pain throughout my body.
I dropped the sword and crouched on my knees.
An unpleasant sweat broke out all over my body.
It was as if I had submerged my body in lava, or rather, as if I had been naked and exposed to extreme cold.
Is it really something a person can endure?
This is, in fact, hell.
"I forgot to mention that the more you pull the sword out, the more painful it becomes. You can pull it out once, but it's better not to do it again. It will probably break your spirit."
"I need time."
"Sure, have as much fun as you want."
I was left alone in a room Lisa gave me.
I dropped the sword again.
I wonder how many times I've done this.
Wouldn't it be better to forget about the demonic sword and strengthen myself by other means?
But Lisa said that no one will follow a hero who is not the owner of the demon sword.
In this dark realm, power is everything, and the symbol of that power is the demonic sword.
Those who cannot use a demon sword are not accepted by the demon race.
In order to make an appearance here, I must first successfully weild this demonic sword.
But it is incredibly painful and agonizing.
It's so painful that I want to drop everything and run away right now.
"I'm not going to stop... I am a hero, a hero who will take over the world and all it has to offer. Toru, I'm going to show you who you've made your enemy."
I grabbed the sword again and quickly pulled it out of its sheath.
A horrifying pain ran through my whole body, and for a moment my vision went blank.
I must have fainted and fallen backwards. And when I came to, I saw Lisa with a big smile on her face standing over me.
I felt a sword in my right hand.
I have taken it out.
"It's more than I could have imagined. I thought you'd give up sooner."
"Don't be silly..."
"That's not true. In fact, the one I gave you was one of the strongest demon swords. Throughout the history of the world, there are only about nine people who have been able to pull it off, which means Sain is the tenth."
I sat and thought about it for a moment.
The most powerful of all demon swords?
What is it?
"Unlike the Sacred Sword, the Demon Sword has its own rank. The Sixth General possesses the second from above. That one is a very powerful sword."
"Did you trick me?"
"That's not true. If you were to become prejudiced of its power, then you wouldn't be able to pull it out. I didn't dare tell you because I was thinking about your well being Sain, and it was hard for me."
Lisa hugged me.
Results are everything to me.
As long as I can get the strongest sword among all the demon swords, the rest doesn't matter.
"Does this mean I've surpassed Toru?"
"I don't know. I don't have the assessment skill, so I don't know his level. If he's that strong, he'll probably come to the Dark Realm, and then we can check it out."
"...Will Toru come here?"
"Since the nations don't have a hero to fight the demon king, they'll have to find a replacement, and I think the Manyu Brigade are the most qualified for the job, so they will be chosen. At least, that's what I would do."
Toru's face looking at me crossed my mind.
That damned nuisance was looking at me with those eyes of contempt.
I will not forgive you. I will make it very clear who is above whom.
Toru, I will kill you.
