The Little Succubus’s Oath

“…No, it’s nothing.”

Looking at the panicked and teary-eyed Lunai, Vivian just shook her head gently.

“I’m just curious, how did you know?”

Vivian was genuinely curious.

She hadn’t felt anything other than the abdominal pain, so how could everyone else sense it?

This was just too unreasonable, wasn’t it?

“Er… it’s-it’s just that… when I get close to you, Lady Demon Lord, I can feel that there seems to be another presence inside you.”

Blinking, Lunai responded cautiously.

“But I can only sense it up close. After all, we succubi are naturally more sensitive to life force, and the other life growing inside you, Lady Demon Lord, seems a little strange to me.

It’s like it’s a demon, but also not, which is why it felt more obvious.”

“Is that so?”

Vivian pondered for a moment and decided she couldn’t be careless, so she covered her abdomen with a layer of mana.

“So, what about now?”

“Um… I can’t feel it anymore.”

Lunai craned her neck, looking left and right, then nodded in confirmation.

“That’s good.”

Vivian let out a sigh of relief.

After all, she couldn’t have everyone she met see that she was pregnant, could she?

That would be too ridiculous.

“But, Lady Demon Lord, how did you get pregnant… Could it be that you were insulted by those damned, lowly humans!? And these humans, should we get rid of them too?”

But then, Lunai’s line of questioning shifted, focusing on the very thing Vivian herself understood the least, while also glancing at the other unconscious human soldiers nearby.

“…’Insulted’ isn’t quite the right word. As for killing them, let’s not. The moment these people die, the life monitoring magic will activate, and our whereabouts will be exposed.”

Vivian fell silent for a moment, carefully thinking back on the spring nights she had spent with the former strongest Hero.

After much thought, she didn’t feel she had lost out in any way.

She replied with some helplessness, while also stopping Lunai’s idea of finishing off the other unlucky fellows.

At the same time, she was observing Lunai’s reaction.

Although she had been timid all along, when humans were mentioned, a murderous intent and hatred still welled up from the bottom of Lunai’s heart.

It seemed that other demons, just like in the game’s setting, still held a natural animosity toward humans, no matter how harmonious they were among themselves or how harmless they appeared.

Even the Lunai before her would probably kill all the other humans with a tear-streaked, timid face if Vivian gave the order.

“Getting pregnant was just somewhat inexplicable. I don’t understand how it happened myself, but I have a premonition that from the day this child is born, it will change the world.”

With that, Vivian couldn’t help but gently stroke her abdomen.

“Lunai, you won’t leak this secret, will you?”

Vivian turned her head to look at the white-haired little succubus, speaking with a hint of a smile.

The next moment, Lunai was startled and immediately fell to her knees.

“I-I swear to you, Lady Demon Lord, I will never reveal your secret! I will swear upon my soul and my life to the great Demon God! I will guard your secret with my life and pledge my eternal loyalty to you!”

She swore her oath to Vivian with sincerity, and even humbly kissed the tip of Vivian’s shoe.

No matter how kind she seemed, she was still a Demon Lord, an existence worlds apart from a little succubus like her.

So Lunai knelt and swore her allegiance without a shred of hesitation—in fact, she had no doubt that if she showed even a hint of indecisiveness, the once affable Demon Lord would twist her head off.

“Get up. You don’t have to be so careful.”

Seeing Lunai kneeling on the ground, even trembling slightly, afraid that she was angry, Vivian was both amused and exasperated, and spoke faintly.

She did want Lunai’s assurance, but she never expected the girl to swear the most binding of oaths.

Still, this was good too. It saved her a lot of trouble—otherwise, things might have gotten difficult.

“It’s about time. I see you’ve recovered quite well. We should prepare to set off and cross the border front.”

After eating breakfast and finishing their hot tea, Vivian didn’t plan to linger.

She got up and left with Lunai.

She hadn’t rested much last night, but as a Demon Lord, her physical constitution was still there.

Going without sleep for a few days was not a problem.

And yesterday, even before Lunai woke up, she had been thinking.

Thinking about future developments, about the future state of the world.

Through Adrian, she knew that she was not the only transmigrator in this world now.

Perhaps there were others.

‘What will their identities be? Heroes? Or a Demon Lord like me? Or maybe they’re starting from scratch…’

‘And, will the future script really follow the game’s plot? After the intervention of transmigrators like us… wait.’

‘If you put it that way, it’s not impossible that the strongest Hero, Lucia, was a transmigrator, is it?’

“…Holy crap, then it would make sense why Lucia didn’t follow the script and came straight to kill me, wouldn’t it?”

Vivian was startled by this thought, but on second thought, it seemed unlikely.

‘If Lucia really was a transmigrator, then she probably wouldn’t have died so suddenly, right?
So the most likely possibility is that another transmigrator was guiding Lucia, or even changing the script… but I can’t rule out other possibilities either.’

‘But no matter what, I’ll have to investigate them one by one later. And re-establishing my own power and intelligence network is also crucial. The most important thing is to have a safe place to give birth.’

Vivian’s current goals were actually very clear.

In the short term, it was to return to her Demon Lord’s Castle, regroup her forces and territory as much as possible, strengthen her armaments, strengthen everything that could be strengthened, and then give birth to the child in her womb.

After that, it was to raise the child, find information about other transmigrators, and also… try to survive in this world.

Starting with the body of a Demon Lord, while not the absolute peak, was still far stronger than many others.

She had so much capital to work with.

Take Adrian, for example.

He went through countless hardships, sacrificed who knows how many lives, and collaborated with the Rhine Holy Church, only to gain a sliver of that power, which barely lasted any time at all against Vivian.

Not to mention more powerful beings.

Just talking about those on the same power level, the other Demon Lords and the top Heroes, Vivian would not be their match in a head-on fight—let alone the even more powerful and ridiculous beings set up for the late game due to power creep.

…Damn it, Vivian had truly never hated the term “power creep” so much.
