"Even so, isn't it a bit much to hole up in your room all day making your subordinates work while you have sex?"
"...Sorry about that."
"I really don't know what you'd do without me."
"You're right. Thanks to you, I can slack off easy. I appreciate it."
"......Here are the documents."
"Mm."
I unfolded the papers my subordinate handed over.
They contained information gathered over six years.
Details on the seven kingdoms across the continent. Key figures in each nation. Their governing structures, current situations, and the whereabouts of revenge targets including my old hero party. Exactly the intel I wanted.
There was nothing on troop numbers like how many knights, mages, or soldiers they had. I could check military strength two years from now. For my plan to crumble the continent from within, what I needed was info on the 'people'.
"Excellent. As expected of you, Irina."
At my words, Irina adjusted the temple of her glasses with her left hand.
"No need for flattery. It's only natural as your direct subordinate, young master."
Her face seemed impassive at a glance, but a small smile played on her lips. And when she'd lifted her glasses just now, her hand had flushed red. Proof she was embarrassed—or pleased.
She's in a good mood, huh. Always so bad at being honest.
I looked up from the papers at Irina.
Violet hair unique to succubi. Neat bob cut. Prim glasses. Cool impression. And a impeccably tailored suit typical of demonkin. A woman who exuded cold efficiency and intellect, the very picture of a secretary at first sight.
That was Irina—my first direct subordinate and second lover.
"As I mentioned this morning, I'm bringing you along on this one."
"I figured as much, but won't it be tough with me sticking around?"
Succubi were especially distrusted by humans among demonkin. Unlike me, with my half-human blood, her purple hair would draw knights and mages the moment she stepped out.
"That's why you'll wait at the safehouse."
"Relay point, got it."
We had to keep in regular contact because of the Demon King, but direct lines weren't feasible while infiltrated. Relays would allow occasional check-ins, though.
"Speaking of safehouses..."
"I set up a few back in my hero days. They'll probably still be there if nothing's happened."
"I see."
Irina was one of the few who knew I'd reincarnated as the hero. She'd been my wet nurse, but knowing about my past life was a big plus for making her my direct subordinate.
"When do we depart?"
"Tomorrow morning."
"Then you should head to bed. It's getting late."
I glanced at the clock at her words.
It was definitely too late to stay up. Spending over twelve hours in the bedroom with the Demon King was the culprit.
"But the Demon King's probably still asleep in my bed?"
"...Then come to my room."
Irina tempted me, embarrassed yet straightforward. A smile spread across my face.
"Sounds good."
I took her flushed red hand and headed to her chambers.
The castle servants we passed in the hall all covered their mouths with one hand, murmuring "Oh my" in hushed tones. Everyone knew we were lovers—and where the corridor led.
A man dragging a woman by the hand to her room late at night. Just the sort of scene the female staff loved.
The moment we entered her room, I roughly tossed Irina onto the bed.
"Kyaa!"
She let out a cute scream as she landed, the faint smile on her face betraying how much she enjoyed this.
My hands tore at her clothes savagely.
"Haa, haaht...♥"
A few rough motions left her in just her underwear.
Grinning, I slid my hand to her lower abdomen.
Squelch...
Her panties were so soaked it was questionable if they even counted as underwear anymore. If we hadn't been together constantly, I'd suspect she'd leaked halfway through.
"Why's it so wet down here?"
"Aa♡ B-Because you, young master, are bestowing your grace on this pitiful succubus... I prepared in advance... hauk!"
It was a far cry from her usual cool demeanor—pure lewd abandon.
But I knew that was her charm. I smirked, snapped my wrist, and smacked her pussy.
"Hnng...!"
"Who told you to get ready on your own?"
"S-Sorry... haat..."
Irina apologized in a slurred, loosened voice. But her face wasn't that of someone sorry at all. More like she wanted me to punish her harder.
It was a familiar expression, yet one I never quite got used to—in the best way. It sent thrills up my spine every time.
I snapped my wrist again. This time with four fingers including the pinky, targeting her clit precisely.
Slap!
"Kyaaahuk...♥"
It sounded painful, but Irina came lightly from that one hit. Her head arched back, body trembling.
"If your pussy gets wet on its own again, you'll get punished."
"Y-Yes, nyaaang..."
"Now, what should you do next?"
At my words, Irina slowly moved her arms and legs despite the aftershocks wracking her body.
She folded her legs into an M on the bed, slid her panties aside with her left hand. Her remaining hand combed through her neatly groomed, soaking wet pubic hair to find her hole.
Her pale, slender finger wrinkled from her juices as she spread her pussy wide, exposing her inner walls.
Squiiiish—
"P-Please stamp this lewd, dripping succubus pussy... with your cock, Masterrr♥"
Fitting words from the succubus who'd taught the Demon King dirty talk.
"I'll pound this pathetic succubus cock-sleeve pussy! Cum on your master's dick!!"
I spat the words I never got used to, no matter how many times, then slammed my raging cock into her hole with all my might, just as she wanted.
"Uhyiiiiit—♥♥"
That night, the sounds of flesh slapping and feminine moans leaking through the poorly shut door kept every servant with nearby quarters tossing and turning sleeplessly, or so I'm told.
"...My body's sore."
"I told you not to push yourself."
"But you'll be busy from now on. When else would you make time for me if not today?"
Irina pouted slightly, burying her face in the pillow.
"Haha, you're always most honest in bed, Irina. Though the absolute most honest is probably..."
I trailed off with a sly grin. She wasn't dumb enough not to guess the rest.
"...What can I do? It's just how I am."
She was innately cool and aloof. Even as a succubus who seduced men, she hadn't racked up much success there.
But her brains and magic talent landed her the administrative role in the Demon King's Castle.
That job let her survive the last war, earn a promotion to fill vacancies, become the sole wet nurse for the Demon King's son—and now, his direct subordinate.
In the end, she'd fallen for the boy she'd raised like her own, living a fulfilling life.
"I wasn't teasing. I like both sides of you, Irina. You're cute either way."
"Hmph, th-thank you..."
Feeling better, Irina lifted her head to gaze at the man beside her—her lord, master, lover, and once her charge like a son.
She'd been shocked learning he was the hero reborn, but now it didn't matter. If anything, it was great for the Demon Army. His thirst for revenge felt real to her.
The greatest foe of old had become the best ally now.
Half-human or not, his monstrous talent and power remained. He looked like an ordinary boy on the surface. Yet even before maturity, he'd beaten a Heavenly King one-on-one. That was just a year ago. No one in the Demon Army but the Demon King in her prime could beat the stronger him now.
In other words, he was currently the strongest demon in the castle.
How strong would he grow after two more years to adulthood? Just imagining it sent shivers down her spine.
"We still have time before breakfast, so catch a quick nap."
"Ah, yes."
His warm voice lulled her eyes shut.
His merits weren't just as Demon Army muscle.
As next Demon King, he was exceptional.
For starters, leadership and charisma. His awakening made him resemble his hero days more, so even without knowing he was the hero, many demons sensed a connection.
Rebellion was natural.
Yet he'd embraced even those demons, earning recognition from his haters. Sure, over half bowed to raw power—demon nature—but the result was loyalty to a strong heir.
Now, few demons didn't follow him, and none doubted he was next Demon King.
As supreme commander, he shone too. Despite frontline focus over headquarters, he had battlefield-wide vision and cool judgment.
Irina could rave about his virtues for hours. Flaws were harder to find.
Same as a man. While even demons eyed succubi with prejudice, he always treated her warmly. The ever-gentle man turned ferocious beast in bed, ravishing her as she craved.
Irina was utterly hooked—couldn't live without him.
"...Hehe."
Lost in thoughts, a dopey laugh slipped out.
"Why the grin?"
"Oh, nothing."
"Heh, alright."
Feeling his affectionate hand stroke her hair, Irina drifted into short slumber.
"All prepared, my son?"
"Of course."
I answered the Demon King's question with a confident smile.
For the departure of the Demon King's own son infiltrating the continent, only a handful were present.
Me, my companion Irina, the Demon King, two of the Four Heavenly Kings in the castle, and the intel unit captain handling spies.
Six total. With two leaving, just four to see us off.
This was top secret.
The next Demon King infiltrating the continent? We couldn't rule out demons colluding with humans. Officially, I was entering secluded training to hasten awakening.
"Using blood for coordinate engraving... impressive."
Elder Lich Imur—one of the Heavenly Kings—suddenly exclaimed in admiration.
"...? I told you before."
"Ah, sorry."
"Forgetting again? Geez."
I gave Imur an exasperated look.
I knew it already, but his forgetfulness never got easier to handle.
"Haha, what can you do? Surviving's a miracle enough."
Imur had held a Heavenly King seat eighteen years ago too.
He'd clashed with the hero party. In the final battle, he'd blocked me—the hero—and barely survived mortal wounds, cursed with this amnesia since.
"Whatever, I'll explain again later. Fix that memory first."
"Heh, I'll wrap it up in two years."
Hence his ongoing experiments for a cure. Minus that, he was top-tier castle power.
I chuckled at Imur's reply, then prepared the warp spell.
Ultra-long-range from Demon King's Castle to the safehouse in Ulstro Kingdom—first destination.
Normally, warp magic wasn't solo. It demanded massive mana, spatial comprehension, coordinates, mana efficiency—tricky stuff.
But I could do it.
The circle had arrays and preps for smooth casting. Plus the bloodline coordinate engravings I'd imprinted when building the safehouses.
Reacting only to my blood let me warp with minimal effort.
"Alright, everyone. I'm off."
"We'll be going now."
The Demon King's eyes reddened slightly at our farewell. Up to two years without seeing her beloved son and lover.
Tears were inevitable.
"I'll visit when I can, so prep for war properly."
"Got it. You watch yourself too, son."
"Yeah, obviously."
Mana flowed from my hand through the magic circle. With a flash, the two atop it vanished without trace.
The Demon King stared at the empty circle a moment, then turned.
"...Then let's get to preparations."
"""Yes!"""
And so the countdown to the new war began.
