Thump, thump.

My heart began to pound.

Cold sweat dripped.

Like a herbivore facing a carnivore.

I looked at the Duke of Extermination.

Her blue eyes were staring intently at me.

Her cheeks and the tips of her ears were flushed red.

Her usual cold expression had softened into one of longing.

Her gaze grew tender.

-Do you know that? The Duke of Extermination always wears a cold expression.

When I first saw her, she seemed like a puppet on strings.

That's what the Emperor had said.

But I had hardly ever seen that expression.

At some point, she became more emotional when standing by my side.

"It's been a while since it's just the two of us. I'm not one to be greedy, but… still, it's been a while…"

"…Not greedy?"

I was momentarily at a loss.

How did I end up like this?

She once pinned me down, claiming it was because other women were eyeing me.

For a week, I couldn't even step outside, completely at her mercy.

"…That was because it was mating season, so there was no other choice."

"Elves don't have such things, you said."

"That's just a facade. Or maybe I'm a bit special, so some flaws might show."

Or…

The Duke of Extermination added, looking at me.

Her eyes gleamed like a full moon.

"It might be because of you."

"…"

I thought such words were a bit unfair.

"Anyway, isn't that the case? When feeling a threat to life, it's natural for reproductive urges to arise."

She was saying embarrassing words without a hint of shame.

'So that's not it.'

The tips of her ears were twitching.

She was shuffling her feet in circles, seemingly embarrassed by her own words.

"Anyway… how is it?"

Thump thump.

My heart began to race.

It wasn't just because of the Duke of Extermination's terrifying words.

"…?"

The Duke of Extermination seemed to notice my unusual state, looking at me with a puzzled expression.

Thump thump.

My heart started pounding loudly.

"What's wrong?"

"...?"

"Though this place is safe, it's still a bit awkward here."

"Why? This is a divine throne no one has entered since it was established…"

The Duke of Extermination's eyes widened as she spoke up to that point.

"Could it be?"

"It seems like I might be that existence."

"…"

The Duke of Extermination's eyes sparkled.

It was as if she were looking at an old investment in Bitcoin that had hit its peak, then reached another peak again.

'…Is this expression right?'

Well, I guessed it was better to think of it as a good thing.

The Demon King would retreat soon.

The sinister figure known as the Sword Demon King smacked his lips and left.

Perhaps that's why.

We were allowed to go elsewhere for a while.

My divine throne.

'There's no particular problem, but…'

It was to prepare for any unforeseen circumstances.

The Divine Name of Eternity.

It's the divine name I was bestowed here.

However, if I did something reckless there, it might affect the divine name.

'Life, love, or abundance.'

Things utterly useless in battle.

Something like that might manifest.

Anyway, we walked towards another place.

"Do you know? The boundary is wide. Because…"

"There are other Dukes here as well. Sword Duke, Flame Duke…"

The Duke of Extermination began to speak.

But it felt like something a teenage girl might be interested in, as if she were forcing herself to speak, awkwardly making something up.

'Oh, come on.'

I gazed into her blue eyes.

The coldness had long vanished.

They were filled with something akin to yearning.

"Shall we?"

"Of course. Let's begin, my dear. I've already blocked any sound or signs, so…"

Gulp.

The Duke of Extermination swallowed as if expecting something tremendous.

…No, rather than this now.

"Elwen."

"…Yes."

Ziiiip.

Elwen unzipped her skintight bodysuit, looking at me slowly as she did so.

Skin as white as snow, almost transparent.

"Don't stare so intently."

"Alright."

Her skin turned bright red.

"…But why use magic on me?"

"You tend to run away well. You did last time too."

"…A man, if he goes on for a week straight, actually suffers."

"Women suffer too."

"You didn't seem to suffer."

"You, you tormented me so much at first."

I couldn't help it.

After dying for the first time, I became too absorbed in magic.

As a result, it accumulated too much.

I delved into magic almost exclusively for five years.

But that was a mistake.

That act ended up triggering something in Elwen.

Since then, Elwen forced me to torment her.

'The Heavenly Demon was the opposite.'

Still, since both suffered because of me, they might be quite similar.

"Were you thinking of another woman just now?"

"…"

A woman's intuition could be surprisingly sharp.

Well, I was at fault too.

"But is this form okay?"

"Now? The body has changed, but the essence and soul are you. That hasn't changed. So, it doesn't matter."

She laughed softly and lightly touched my body with her slender fingers.

"Your previous body wasn't bad… but this one is even better. It's so flawless, it would put most to shame."

"Well, I've done a lot of research in that area."

"Yes, the more perfect the body, the better. Don't worry. I've trained my body quite a bit too. You won't be disappointed."

Elwen said that and removed my pants.

"Hmm… this part has gotten bigger. It's a bit difficult when it's too big."

She prodded and her eyes formed crescents.

"But what about the other women?"

"…"

"Well, I know you're a one-woman kind of guy. But the problem is the women who fall for you."

"…"

"Don't worry too much. As long as I have you, nothing else matters. But… since I'm the one who claimed you first, I should at least have some privileges, shouldn't I?"

She wasn't my first time.

Because someone else had taken that spot during my first life.

But why did women emphasize the first time so much?

'The Imperial Princess, the Witch, the Dragon Queen. And even the Heavenly Demon…'

They all had an obsessive fixation on being the first.

I gently stroked the Duke of Extermination's cheek. It was a soft and tender sensation. Her skin was also quite elastic.

Now.

I should forget all those things and focus on Elwen.

I quietly pressed my lips to Elwen's.

The Duke of Extermination.

Elwen Ksaraxia.

There's no one at the boundary who didn't know her name.

None existed.

With doll-like looks and being one of the few mature transcendents.

A solitary figure who could face several transcendents or gods.

Such a figure wouldn't be easily meddled with.

However, there were many forces that wanted to incorporate her into their ranks.

The principal, Kwon Sora, was one of them.

But they couldn't succeed. She moved like a noble crane, untethered.

She didn't join any faction.

She didn't form personal connections with anyone.

There were a few transcendents in the empire.

Yet, she hardly interacted with them.

Even titles like Sword Duke or Flame Duke were nothing compared to the Duke of Extermination.

So she didn't bother with them.

While it was important to incorporate her into their faction, her task of eradicating the demons was more crucial.

Not joining forces opposed to her was also a factor.

But then.

'…What is this situation?'

The Duke of Extermination was seen smiling broadly.

At first, he doubted his eyes.

She was like a doll who didn't know how to smile.

'That is…'

The reason she was smiling so broadly.

And the reason she suddenly joined my faction.

There was nothing special.

Just because Han Seojin was there.

Without Han Seojin, she returned to her cold expression.

Sometimes, she moved with a blush on her cheeks.

Sometimes, her eyes lit up, as if she could kill someone with her gaze.

'And in that case.'

It was when Han Seojin, who had been appointed as a professor…

…was teaching female students and she tried to kill someone out of jealousy.

Shin Yura, for example.

Or Yoo Seolrang, whom he brought along.

"W-We're, r-really o-okay, r-right?"

Yoo Seolrang said, trembling.

"Maybe?"

"M-Maybe!?"

"Elwen's gaze is a bit sharp, and she has a cold personality, but once you get close, she's friendly."

"…Seems like it's limited to the professor."

"No, she was like that with other kids too."

Han Seojin thought for a moment, then exclaimed, 'Ah.'

"You guys are actually in a better position."

"How are we better?"

"Back in the day… I mean, before I became the Purple Tower Master."

Han Seojin could confidently say he was relatively normal back then.

Because of that, he used to get along quite well with the boys.

But at some point, Elwen started paying more attention to the boys than the girls.

'I didn't do anything wrong, though.'

She said the boys following me looked like fanatics.

Since then, she suddenly started to guard against the boys.

'I don't even want to understand it now.'

Han Seojin thought up to that point and then hesitated.

Thump thump.

His heart began to race.

Why?

His divine throne was far from here.

There were things he wanted to know about it, but he had to come here because he spent too much time with Elwen.

So, it had nothing to do with the Divine Throne.

Thump thump.

His heart beat once more.

Only then could he understand what was happening.

'It's resonating.'

Heaven-Surrendering Godly Technique.

It was signaling that his other half had come here.

'Why?'

Why did the Heavenly Demon come here?

Cheon Murin should be in the Middle Realm.

Just as that question was about to end.

Elwen stood in front of him.

Her legs trembled slightly.

"What are you doing right now?"

A cold voice.

A purple aura tinged with black began to envelop the surroundings.

There was no sense of impure power.

Demonic Qi.

A power drawn from human emotions. It was different from that.

If one walked the path of the demon, they would master demonic arts.

At its pinnacle.

Heavenly Demon's Godly Technique.

It surrounded the area.

"Why are you next to my man?"

Cheon Murin quietly seethed with anger.
