Chapter 3

300 years ago.

In an era when the power of humans was still weak, a legendary hero was born.

The hero's name was "Oga."

According to legend, he possessed a muscular body over 3 meters tall and had an incredible talent for magic, making him unbeatable by any human. More than anything, what is passed down in the legends is his kindness. He saved countless people by slaying numerous evil demons and beasts who were oppressing humans.

And finally, after defeating the two most powerful beings known as the "Demon King" and the "Dragon King," he is said to have withdrawn from the battlefield and disappeared from the people's sight.

"I can't believe that the 'Demon King' and the 'Dragon King' are sealed here..."

If this were known in the outside world, it would cause a huge commotion. Still, why did the legendary hero seal them instead of defeating them? Was it because they were too strong to defeat?

Hmm. No matter how much I think about it, I can't figure it out. It's better to think about escaping now rather than pondering the distant past. I would have been at a loss in this white space alone, but fortunately, there are two people here who are much more amazing than me.

They might know a way out of here. It would be a lie to say I'm not scared, but I have to muster the courage to speak up!

"Umm, excuse me!"

"Hmm? What's wrong, boy?"

The one who responded was the Demon King lady in the sexy outfit. Her name is Testarossa. She seems smart, so she might know something.

"Um, do you know how to get out of here?"

"Out of here, you say? Hahaha!"

Testarossa suddenly burst into laughter. Did I ask something so ridiculous?

"Hehe, I'm sorry, boy. I'm not making fun of you."

"Then why are you laughing so much?"

"Because it's impossible to get out of here. And yet, you're asking seriously how to get out."

"It's... impossible to get out!?"

Her words made me feel weak, and I involuntarily dropped to my knees. No... to be trapped in this empty place forever!?

"Of course it's impossible. If there was a way out, we would have escaped long ago."

The one who spoke was the Dragon King, who had returned to her young girl appearance. She's right. The Demon King and the Dragon King, the strongest duo, haven't been able to escape for 300 years. There's no way a mere human like me could get out. It's no wonder they laughed.

"We are sealed by the hero's magic. Because of this, even if we try to tear through dimensions to escape, our souls cannot leave this space. Look, here's the proof."

The Dragon King suddenly lifted her clothes to show me her chest. Under her clothes, there was a small magic array. This is the sealing magic.

Naturally, I don't have this magic array on my body, even though I fell into this infinite prison.

I searched my entire body, but there was no such thing anywhere. Why?

"Um, this is..."

"Wh-what!?"

Testarossa suddenly started touching my body! Ah, it's embarrassing. I thought about resisting for a moment, but I was powerless against her incredible strength and could only be groped.

After thoroughly groping my body, Testarossa finally stepped back, seemingly satisfied. Ah, I can't get married now...

"There's no doubt. This boy doesn't have the sealing mark...!"

"What! Why do you not have the sealing mark and yet you're here!"

"Ah! Let go!"

The Dragon King grabbed my collar and shook me violently. If Testarossa hadn't pulled her away, I would have fainted.

After regaining my composure, I told them how I got here. After listening to my story, Testarossa lowered her eyes in thought and then opened them with a wicked smile.

"I see, I understand the situation. This boy accidentally entered a dimensional rift. That's why he wasn't formally sealed."

"Can a dimensional rift just open up by accident?"

"This space has existed for nearly 300 years. It would be more unusual if it hadn't started to break down."

That's true.

It must mean the hero's power is that incredible.

"The important thing is not that! The important thing is that if you're not sealed, you have the potential to get out of here!"

"Get out of here...!?"

Her words made my heart feel lighter.

Yes! I don't have to spend my whole life here!

"Then what do I need to do!? If I can get out, I'll do anything!!"

"Anything...?"

"Anything...?"

When they heard my words, they both gave me a very wicked smile.

"Eh? What...?"

"The only way to get out of here is to open a hole in the space yourself. In other words, you need to become much stronger than you are now."

"Open a hole in space...!? I can't even swing a sword properly! I'll be an old man before I can learn that!"

"Don't worry. You don't age in this space. Plus, we'll help you train. In return, if you successfully escape, you must help us get out of here, okay?"

They kept getting closer.

Ah, it's too scary. I might be the only person to be cornered by the Demon King and the Dragon King at once.

"Do I... have a choice...?"

With teary eyes, I tried to assert my right to refuse. But they smiled like angels and said devilishly,

"None! ♪"

And so, my long, long days of hellish training began.
