Side Story: The Happy Life of an Evil Demon King~

Side Story Setting and Premise: From the moment of her transmigration, Sibyl leveraged her instant-kill passive ability to fortuitously slay Alan with a Minor Fireball, successfully intimidating Carol and Evelyn. After several wars, Sibyl became the sole ruler of the Western Demons, growing into an unparalleled Great Demon King whom both women could only submit to (without sarcasm).

On the tall black crystal throne, a petite pink-haired loli slouched in a rather unladylike pose, propping her chin up with one hand.

"Sister Carol~ Come here for a moment~"

Sibyl called out to the black-haired beauty beside her in a soft, sweet voice. She didn’t look at Carol, merely crooking her little finger slightly with her right hand as a signal to approach.

Carol swallowed hard, a flicker of panic crossing her face. But she forced a smile, stepping forward and kneeling on one knee. "Great Demon King," she asked respectfully, "what do you need?"

At this, Sibyl pouted as if wronged. "Uwaa~ Can’t I call you without a reason? My dear Carol-sis~sis~"

"N-no, of course you can, Great Demon King. It’s an honor to be summoned by you." Carol replied hastily.

"Oh la la, is that so?"

Sibyl murmured absently while reaching out with her tiny hand. She casually played with Carol’s silky long hair, her fingers soon drifting to the lone horn remaining on the black-haired beauty’s head.

Since Sibyl hadn’t spoken, Carol dared not move. She stood frozen as the little demon-like ruler fondled her noble head.

But Sibyl quickly grew bored. Her gaze shifted to Carol’s chest.

Such perfect shape and curves—surely they’d feel wonderful to squeeze?

With this thought, the pink-haired loli perked up excitedly. In a commanding yet babyish tone, she declared: "Stand up. Let me touch your breasts."

"What?"

Carol flinched, instinctively stepping back.

"I said~ I want to touch Sister Carol’s breasts~ Must this Demon King repeat it a third time?"

Carol’s eyes flickered with inner struggle. Finally, she nodded in submission. She rose from the floor and walked to stand directly before Sibyl.

Then she dropped into a perfect horse stance, leaning forward so her chest aligned with Sibyl’s small hands.

"Pfft..."

The pose was so absurd that the petite Demon King couldn’t hold back a snort.

"Sister Carol, are you here for a product inspection? I’m not a quality checker, and your breasts aren’t merchandise. Can’t you use a normal pose?"

Carol’s fair face flushed red. But under Sibyl’s imposing aura, she suppressed her embarrassment and asked: "Then what pose does the almighty Great Demon King Sibyl desire?"

"Uwaa~ I want Sister Carol to hold me~"

Sibyl feigned coyness, though a mischievous smile played on her lips. "Your princess carry has always been so comfy~ Lying in Sister Carol’s arms while being served—that’s what I truly want. Hurry up, I can’t wait any longer~"

"Your will be done, almighty Great Demon King Sibyl."

Carol raised no objections. She carefully lifted the pink-haired loli from the throne and stood motionless.

Sibyl noticed this. "Sister Carol, why are you standing? Sit down already~"

"But this is your seat. As your subordinate, I—"

Sibyl frowned impatiently. "Sit."

The black-haired beauty had no choice. Trembling slightly, she sat on Sibyl’s throne.

"Why so stiff? Don’t you fear your breasts will harden and ruin the feel? If I’m unsatisfied, I’ll punish you with a month of paperwork!"

"But I’m already handling this month’s files?"

"Then next month’s yours too!"

Carol instantly adopted a compliant expression. "Understood, Great Demon King. I’ll ensure your satisfaction."

"Hehe, that’s more like it."

The petite loli Demon King, cradled in her subordinate’s arms, reached out a wicked little hand toward the beautiful Succubus.

"Mmm, not bad~"

After a moment’s exploration, Sibyl gave her approval. "Compared to Evelyn, whose chest can’t even fill one hand, yours feels much better~"

"What? Evelyn was also... enjoyed by you?"

"Of course. That one’s utterly clueless. At first, she tried using her daughters as shields—what’s there to touch on those flat-chested girls? She kept resisting, forcing me to use mind magic. Touching an unresponsive doll-like lady is no fun at all."

Sibyl shook her head, recalling an unpleasant memory. Then her tone brightened. "Sister Carol is truly the best! So gentle, so thoughtful, great at cooking, and with such a lovely figure. Ah, what blinds my eyes~"

Perhaps feeling cheerful, Sibyl unconsciously flashed a sweet smile.

Watching the Demon King who groped her while looking adorably cute, Carol couldn’t help but want to stroke the loli’s little head.

Of course, she only dared to think it. Actually doing so would surely provoke the Great Demon King’s fury.

*Sigh.*

The black-haired beauty sighed softly. The summoned Demon King had completely turned the tables—a mischievous little demon she couldn’t defeat, teasing her daily. What could she do?

Yet Sibyl’s smile in her arms was so pure and lovely, stirring an urge to protect her.

*This isn’t so bad after all...*

"Sister Carol~ Your eyes tell me you want to stroke my head, right?"

Just as Carol drifted off, Sibyl suddenly spoke up.

Carol jolted. "Your unparalleled cuteness makes anyone think that. Pay it no mind, Great Demon King. Please continue."

At this, Sibyl stopped her hands. A smile spread across her face. "Sister Carol~ You want to do this—right?"

The pink-haired loli shifted to a pitiful pose, kneeling on Carol’s lap. She deliberately rubbed against the older girl while murmuring softly: "What are you hesitating for? Will you miss this precious chance for a head-pat from this Demon King?"

Carol finally lost her last shred of reason under the Demon King’s deliberate temptation. Her hand reached toward the loli’s small head.

But Sibyl blocked her just before contact, a sly curve on her lips. "Wait~ I have something to say~"

"W-what is it?"

"Sister Carol, let’s make a deal~ If you sign a contract pledging to become my eternal subordinate, I’ll let you enjoy my body. Sounds fair, doesn’t it?"

As she spoke, Sibyl lifted Carol’s chin. "Of course, you have no right to refuse, Sister Carol~ Be mine—forever and ever—as this Demon King’s person~~"
