Evelyn, now fully materialized and standing by the bed, turned and rubbed her perfectly round, stinging ass.
The skin there was still bright red where his palm had made contact.
"Owww," she whined, sticking out her lower lip in a perfect pout.
"That really stings, Nii-san. You hurt your little sister too much."
Kaelen slid off the bed, looking down at her.
"You deserved it," he said firmly.
"And if you ever pull a stunt like that again, trying to manipulate me with your scent or your 'sleeping' act, I'll spank you until you can't sit for a week. Got it?"
Evelyn's eyes, still glazed with a mix of pain and lust, widened.
Her voice dropped to a husky, breathless whisper.
"Yes~ Daddy~"
Despite her flirting He focused himself to stay focused.
Evelyn giggled at his reaction and turned toward the wardrobe.
She pulled out a set of simple, well-fitting black trousers and a soft, dark gray shirt.
She tossed the clothes at his face.
"Dress up! We're going out."
Kaelen caught the clothes and started pulling them on.
"Where are we even going, Evelyn?"
"To the Royal Treasury, of course!" she replied, already heading for the door.
"We need to weaponize my sweet Nii-san. You can't fight the Holy Grail War with C-rank stats, even if you are irresistible to all women."
She opened the door, and Kaelen followed her out into the grand corridor.
As soon as they stepped onto the polished stone floor, a new, small purple screen flickered into existence right in front of Kaelen's eyes.
> 💖 Mini Quest Alert 💖
> [Quest: Select the Weapon from the Demonic Royal Treasury.]
> Reward: Skill: Aura of Erotic Hypnosis (Passive) - Subtly influences non-bonded partners to be more receptive to Apostle Kaelen's advances, making them crave intimacy with him when he focuses his Lust Aura.
> Failure: None
> Accept? (Yes/No)
Kaelen sighed heavily, rubbing the back of his neck.
"God damn it, Evelyn. Are we going to have a quest pop-up for every single thing I do?"
Evelyn, who was still fully dressed in her tight purple dress, walked ahead of him, skipping slightly.
[✿Think of it as helpful guidance, Nii-san! And hurry up and accept! That passive skill is a must-have for charming our Empress!✿]
the System's voice... or her voice, giggled directly in his mind.
He quickly tapped 'Yes' on the screen.
"Where is the Empress's office, anyway?"
Kaelen asked out loud, catching up to her.
"Ignisarya's? It's on the east wing," Evelyn said, not even slowing down.
"We need her. She's the key to everything right now. She's the Empress; with her, we can take anything we like from this palace...including the strongest weapons."
She slipped right beside him, pressing her body close to his arm.
She leaned up, her lips brushing his ear.
"And also," she purred, "I'm going to hook you up with her, Nii-san. I'll make sure she's begging for your attention. So, you better pick up the hints and don't stay stupid and still like those Japanese MCs who can't see the obvious."
Kaelen stopped dead, forcing her to stop too. He looked at her with a dubious expression.
"Hook me up? What is this, Evelyn? Have you developed some kind of cuckold fetish now that you're an Ascended Demoness?"
Evelyn threw her head back and laughed—a sound that was pure, innocent joy, mixed with something far older.
"That's not entirely true, Nii-san!" she laughed.
[✿My soul is now interconnected with yours for all of eternity inside your body, Nii-san. I know no one will ever, ever take my place in your heart. All those other women? They will be below me. I'm the one who will make sure they are worthy to share your time!✿]
She stated in his head, her voice full of unsettling confidence.
Kaelen shook his head slowly. "You're quite full of yourself, aren't you?"
Evelyn placed both hands on her hips, striking a pose that highlighted her curvaceous figure.
"Of course I am. This body is made only for Nii-san's preference, after all."
Kaelen narrowed his eyes.
"Isn't it the same body you had on Earth?"
Evelyn simply gave him a small, mischievous smile that didn't confirm or deny anything.
"Wait... If your soul is in my body," Kaelen pressed,
"then who am I talking to right now?"
Evelyn shrugged, her pink hair bouncing.
"This is now just a doll for me to materialize into, Nii-san. Lilith split my soul from it and put the essence into your soul as I wished. I'm literally the System now."
She leaned in close again, lowering her voice to a suggestive whisper.
"I can customize this body for you whenever you want, too. You want a milf mommy figure, bigger breasts and wider hips? Or maybe a tighter virgin high school teenager for a challenge? Just tell me."
Kaelen stared at her, utterly speechless.
"Your kinks are seriously getting off the roofs, Evelyn."
She simply giggled in response and didn't wait for him to catch up.
She led him straight down the corridor, turning a corner that led to a pair of large, black doors.
A blonde maid, dressed in the same uniform as the others, stood by the door.
Evelyn approached the maid without hesitation.
"Excuse me, we need to speak with the Empress. Please call Ignisarya out for us."
The maid bowed deeply, her head lowered.
"Right away, Holy Daughter." She then turned and slipped inside.
Kaelen leaned toward Evelyn.
"How did you know her office was here?"
Evelyn looked at him, utterly serious.
"Are you seriously asking me that when I'm almost on par with a goddess, Nii-san? I can sense her power signature."
Before Kaelen could reply, the door cracked open.
Ignisarya emerged, composed and respectful, her beautiful crimson eyes focused on them.
She said. "Did you require anything?"
Evelyn stepped forward, her most bubbly, innocent smile in place.
"Ahh yes..The Goddess Lilith told us to come and get 'that' weapon for Kaelen," Evelyn announced.
Ignisarya's crimson eyes widened instantly in surprise, her composure faltering for the first time.
"But... but that weapon..." Ignisarya stammered.
Kaelen looked from the Empress to Evelyn, confusion etched on his face. "What weapon, Evelyn?"
Evelyn's smile turned cold and sharp, her eyes gleaming with power.
"The Weapon of the previous Demon King."
