As A Result of Trying To Live An Erotic Slow-Life, I Have Become The Underground Ruler of This Upside-Down Otherworld - Chapter 91: Chapter Four Interlude: Two Weeks’ Tale - Serika

Chapter 91: Chapter Four Interlude: Two Weeks’ Tale – Serika

To start abruptly, Serika does not have hobbies.

Or rather, it is not just Serika—perhaps it should be said of ugly women in general.

For ugly women, whose lives are centered on daily survival, there is no such thing as leisure.

If they had any free time, they would scramble to secure work, even if it paid only half the promised reward, to make ends meet.

Recently, Towa has taken up making stuffed animals, having found both time and resources, but such cases are exceedingly rare.

Among ugly women, someone like Mia, who indulges freely, is practically one of a kind.

Perhaps those belonging to a Family are different, but for those trying to live in the surface world without reaching into the underworld, it can be said that almost none have leisure or surplus.

In short—

“What should I do?”

Having arrived in Adelina and parted ways with Arius, Serika found herself with an abundance of time.

She is not accustomed to having time for herself.

If working tirelessly for survival counts as time for herself, that is different, but she is unaccustomed to a state where she can live without immediate concern.

This is especially true for Serika.

With a level of devotion to Arius that could be called fanatical, simply waiting idly for her master is unthinkable.

“Ugh, uhh…”

She considered using her adventurer’s license to take on a quest.

However, doing so would mean she could not remain constantly available for contact.

She has, of course, been informed of what Arius is doing here.

Fundraising—he came to make money.

And while it is not a certainty, she can guess how Arius intends to achieve this.

“Arius-sama… No, I don’t want that…”

Imagining Arius selling his body to unfamiliar women, Serika half-sobs.

Indeed, it is easy for anyone to imagine. For a man to make quick money, there is little else but selling himself.

In fact, that was Arius’s intention.

Master—Eld—would introduce him to wealthy, beautiful women, and he would earn money through his body.

Thus, acting separately from Serika was, in a way, his kindness—to avoid triggering her succubus instincts.

Serika has grown accustomed to Towa, Mia, and barely Shuri being embraced by Arius.

She can tolerate those tentatively recognized as part of the Family being with him.

But she cannot endure him negotiating with strangers.

Serika is exceptional—truly exceptional.

Not only in her abilities but also as a succubus.

Because of this, Arius’s kindness is rendered futile.

Her chest aches merely from imagining it. Her succubus instincts, her acute senses, are far too sharp.

Serika is aware.

If Arius tries to sleep with someone in an unfamiliar place, she will sense it.

“Ugh…”

With an excess of time and an impulse she may not be able to endure, Serika is deeply troubled in two ways.

This is Arius’s path—what he is doing is necessary to advance along it.

She understands this intellectually. Because she understands, she wants to endure—she must endure.

In the room prepared for her stay—

She throws herself onto the bed with a bosun—

“Please, let me be able to endure.”

Clutching the pillow as if in prayer, she closes her eyes.

※

And so, five days pass.

Strangely, the impulse she anticipated never arrives.

The five days pass so calmly, so uneventfully, that she begins to wonder if she is not as fixated on Arius as a succubus as she thought.

“What is Arius-sama doing?”

Now, she even begins to worry.

What if he has been caught up in something troublesome, unable to focus on fundraising?

However, the magic stone she carries is a special creation by Mia.

Even without active use, it would alert Serika if any harm came to Arius.

“Ugh, hmm?”

Perhaps she should simply go see him directly.

That would not only lift her spirits but transform them into pure joy.

“No, no! I mustn’t interfere with Arius-sama!”

Of course, acting on that impulse would ruin everything.

He is not sleeping with them, but Arius is meeting with beautiful women.

Serika does not know this, but her hasty assumptions leave her uncertain of what she might do.

“Right, right. Mia-san said it, didn’t she? Trusting Arius-sama means this, doesn’t it?”

Recalling the time Arius went alone to Rozaria’s hideout, Serika thinks Mia’s words were cool.

They also hit the mark, especially for her.

With her blind worship of Arius, she felt as though she had been called out.

It is not that she does not trust him. But preventing him from doing something potentially dangerous might be akin to doubting his potential.

In the end, Arius returned safely.

More than that, he seemed to have grown. Enough to make her realize she cannot remain as she is.

“That’s it. I can’t stay like this… I need to grow too.”

Finally, in Adelina, Serika decides how to use her time for herself.

Clenching her fist with a mun and standing up—

It could be said that the very act of making this decision is her greatest growth, though she is unaware of it.

“Growth, huh…”

To reiterate, Serika is an exceptional succubus.

More precisely, she is a half-succubus, half-incubus with strong succubus blood.

Her combat abilities are exceptional, and though overshadowed by Towa and Mia, she is highly intelligent.

Her mastery of mana is so advanced that even the Snakes say they cannot match her.

To put it plainly, she is a superhuman among superhumans.

Arius told Rozaria that someone could reduce a city block to ash—that is Serika, if she chose to do so.

If she were considered beautiful in this world, she might well be a royal adventurer by now.

“Mmm…”

Because of this, she struggles to find areas for improvement.

Her excellence allows her to fully understand her own capabilities.

“Maybe… um, erotic things?”

Blushing as she says it, she is a maiden alone.

Anyone observing might scoff, “Why is this Arius-exclusive lewd onahole blushing?”

“Hmm…”

With a shuru-shuru of rustling fabric—

She removes her usual nun outfit, standing naked before the mirror.

“…Why does Arius-sama embrace a body like this?”

Large. No, excessively large—her breasts.

Her hips, plump yet firm, perfectly rounded.

Just these two features mark her as having the body of an ugly woman.

It is not just Serika—all ugly women deeply believe they are unattractive.

Towa, Mia, Shuri, Kazune, Ririeru, Sonya—all the women serving Arius share this belief.

In simple terms, they believe they possess something beyond their appearance that aligns with Arius’s tastes.

For Serika specifically, her incubus traits shape her body to Arius’s preferences, yet she still does not consider her appearance or body beautiful.

“Nn…”

Touching her breasts, she feels nothing.

When Arius touches them, her womb weeps, preparing instantly, but her own touch elicits no pleasure.

“As expected, I feel nothing.”

Even imagining Arius’s touch or mimicking his caresses, her body does not respond.

Her nipples, which harden under his touch, remain soft. Her pussy, which would drip onto the floor, stays dry.

“Well, it’s… somewhat amusing?”

Lifting and kneading her breasts, poyo-poyo—

She finds the pliable, shape-shifting flesh interesting.

“Muu.”

Perhaps it is a downside of becoming Arius’s exclusive onahole.

Her body feels nothing from anyone else’s touch—not even Towa or Mia. If a stranger tried, their hand would meet empty air.

“My body is a dead end. Then… my inner self?”

Wearing only underwear, she sits in seiza on the bed.

If there is something to improve, it must be internal.

She realizes that while she has mastered her succubus abilities, she has never explored her incubus side.

Her faint incubus blood has only manifested in shaping her body to her beloved’s ideal.

She does not like to recall it, but the incubus she knew possessed many more abilities.

Succubi are lust demons; incubi are dream demons.

Succubi seduce in reality; incubi craft ideals in dreams, indulging in debauchery.

Thus, incubi have the ability to lure people into dreams and to discern their ideals.

“Dreams… perhaps hypnosis? That’s probably beyond me.”

Like a succubus’s charm, but since her charm only works on Arius, she assumes the ability to lure into dreams is unattainable.

Then, the ability to know ideals.

“My body is slowly reshaping through this ability, isn’t it? Hmm…”

It is a slim chance, but any new power would likely stem from this.

Though knowing someone’s ideal appearance seems of little use.

“Wait, hold on.”

It dawns on her.

There have been times when she instinctively knew what to do without Arius saying anything.

Naturally, this pertains to matters in the bedroom.

Could that be due to her incubus traits?

“Yes, yes! There were times I just knew what to do.”

The orgy with the Snakes at the Mage Guild.

When Arius uttered her name afterward, she instantly understood the unspoken meaning.

If she could activate this ability deliberately—

“Could I become the ideal… onahole?”

Her previously unresponsive body ignites with heat.

She vividly imagines herself adapting to the form Arius desires.

“Okay, okay…!”

She has found her purpose.

With her fist clenched once more, she stands upright—

Forgetting she is in her underwear, she dashes out of the room—

“Kyaaaaa!?”

“S-Sorryyyyy!”

She is met with a scream.

※

Now, Serika’s incubus training could be called a form of asceticism.

For three days, she focused her consciousness on random men in the streets, peering through what could be called magic eyes to discern their ideals.

As expected of Serika, she succeeded in mastering it, though her control remains imperfect.

In exchange, she was banned from a café overlooking the main street. But for an ugly woman in a nun outfit to gaze at passing men with sparkling eyes, being banned is understandable.

“Fufu, fufufufu.”

Nevertheless, she is delighted.

A message came through the magic stone—they will rendezvous soon.

She plans to comfort a weary Arius with this new power.

She has already bathed twice.

Splurging her personal funds, she has lightly coated her body with scented oil.

In short, she is fully prepared.

A new, exclusive onahole—Serika reborn—ready for him to savor fully, a sloppy grin spreads across her face.

“He’s back!!”

The prearranged knock.

Beyond the door, it is undoubtedly Arius.

Bedsheets? Prepared.

Her reflection in the mirror? Perfect.

Ready to be ravished? Absolutely.

—Here we go, Arius-sama.

“I’m back.”

“Welcome back! Arius-sama!”

As she speaks, she activates her new power.

It is a premature action, but Serika is incapable of such judgment now.

And then—

“—”

Arius’s ideal.

The deep-seated desire he harbors for Serika.

She probes and catches a glimpse of it—

“—Kyu♡”

“Huh? Eh? Whoa!? S-Serika!?”

Overwhelmed by what floods in, she loses consciousness, her face beaming with joy.
