"That's far enough. Perfect."
The boy rose from his chair and approached her. He extended his right hand, brimming with concentrated mana, toward her lower abdomen.
His fingertips felt warm. She bit her lip at the sudden heat spreading into her cool skin. She barely stifled the moan threatening to escape. If it had slipped out, she knew it would've been far more lascivious than any before.
"Mmm. Good."
She wondered what kind of spell required placing his hand on her lower belly.
At that moment, he began chanting the incantation. Only then did she realize the mana in his right hand wasn't gathered to kill her, but to cast this spell.
Her fear had been so overwhelming she'd failed to distinguish it from offensive magic. Disgraceful for a mage, she thought just as—
The brief chant ended, and the magic seeped into her.
"Haaah—!!"
Before she could hold it back, a lewd cry burst from deep in her throat.
"Hauk! Hngh... Haaah!"
An indescribable sensation erupted from deep within her belly, overwhelming her entire body.
Her mind blurred for an instant, her raised arms nearly giving way, but she forced herself to hold the position. Whether he approved of her resolve or was satisfied with the spell's success, the boy nodded with a pleased smile.
"...Nghh...♥"
She had no time to decipher his expression.
She focused everything on enduring the strange sensation coursing through her.
She bit her lip until it bled. The metallic taste sharpened her mind slightly. Mage's instinct, perhaps—she tried to analyze the unknown feeling.
Her body temperature rose, her lower belly throbbed, and an itch built around her chest and groin.
...Ah.
Only then did she realize it was sexual arousal.
It felt just like the time she'd snuck a peek at what she thought was her master's secret archive as a child, only to discover it was an erotic tome—and masturbated for the first time.
She'd missed it in her tension, but the demons had mentioned charm magic as the base for this spell. That made sense. A spell to seduce the mind and inflame the body.
But it was strange. Charm magic was unique to succubi. How could a male like him wield it? She couldn't dwell on the question—the rising pleasure was too much.
The ecstasy raced through her veins, circling her body until it reached her head. It felt like something burst from the crown of her skull.
"Ah, ah... Aah... Haaah—!!"
Her head snapped back. Her toes curled involuntarily, her hands clenched, crumpling her skirt. Her vision sparkled like fireworks exploding before her eyes.
After a couple of spasms, she finally regained her senses.
But she was exhausted. Not just tired—it was like she'd depleted every drop of mana in her body, leaving her overwhelmingly drowsy.
"Haa, haa, haa."
"You did well."
"Y-yes, mastehhr."
She slurred her response to his praise. It slipped out reflexively.
"It took nicely."
As he spoke, he stroked Bilma's lower belly.
She looked down at where his hand rested.
There, in pink ink, was a small heart shape.
Viewed alone, it was just a tattoo. But the color, the shape, and its position over her womb made it feel utterly obscene.
"Still, just drawing it gets me only to stage one. Hmm, yeah—effects that strong come with heavy restrictions."
"Wh-what... is this...?"
Every glance at the tattoo sent a little jolt through her body.
"Oh, this? I call it Lewd Tattoo Magic. This one's the Tattoo of Submission."
"S-submission?"
"Don't worry. It won't make you drop dead if I tell you to. You'll just... obey me a bit better."
It was a lie.
Not that it'd kill her on command, but it was far more than that. Every lewd tattoo shared certain effects, and this one had special obedience powers to match its name. But he kept that hidden.
It'd be more fun that way.
"Anyway, I'm still inexperienced, so it must've drained you. Sleepy? Go ahead and rest."
"Ah, y-yes..."
She closed her eyes as if she'd been waiting for permission and collapsed. He caught her waist, but even if she'd hit the floor, she wouldn't have woken.
He carried the deeply sleeping Bilma to the bed in the corner and laid her down.
"Hmm, looks like I need more mental domination to raise the stage. That's a restriction, fine—but it eats too much caster stamina and mana. Gotta tweak that."
Reviewing the spell, he sat on the bed's edge and gazed down at her.
He brushed away the sweat-dampened strands clinging to her lips. Golden blonde overall, but shading to gray at the tips. He'd never seen it himself, but he'd heard the description many times.
Her face and details matched the file Irina had given him exactly. He'd overlooked her since her revenge priority was low, but the hair jogged his memory.
"Who'd have thought I'd cross paths with that bloodline. Is the goddess aiding my vengeance?"
Of course not.
The only god in this world was the Goddess, and she despised demons.
Unable to intervene directly, she influenced the continent through oracles and such. She'd chosen him as Hero via oracle too. Though she'd never foreseen this.
"Still, this is fun."
A wicked laugh echoed through the dungeon, at odds with his boyish looks.
"So, how do you plan to infiltrate?"
"Hm?"
Irina, back from reinforcing patrols around the dungeon, asked him.
"Didn't I tell you?"
"You only said you'd infiltrate Ulstro Kingdom."
"Ah, my bad."
He glanced around, thinking briefly.
Irina and the now-awakened Bilma were there.
He'd originally planned to station Irina here as a relay to the Demon Castle.
But he'd changed his mind. By coincidence, Bilma had appeared—a fine pawn. She seemed perfect as Irina's assistant. Using them both would greatly aid his conquest of the kingdom.
Having sorted his thoughts, he spoke.
"First, I'll sneak into the palace."
"...Pardon?"
"H-how?"
Both women looked stunned at his declaration.
"Simple. I'll use the martial tournament."
"Excellent. That has real potential."
"Eh? What's a martial tournament? ...Wh-what're you staring at? I-I might not know!"
Bilma squeaked, embarrassed by their gazes.
"A demon explaining the martial tournament to a continental. Unbelievable."
"You probably just forgot. You've heard of it: the Hero Memorial Martial Tournament."
"Oh..."
Even the full name didn't ring a bell for Bilma. Irina sighed softly and continued.
"Ulstro Kingdom suffered the second-heaviest losses against the Demon Army, after Ventorino. Ventorino lost its royal line entirely, but Ulstro lost its Hero—the sole Ulstro native in his party—and the crown prince too. The people were lost without leaders."
"That's when the current queen stepped up. She rallied the surviving nobles and led the masses. But talent was scarce. So she got clever. Just three months after the war, she hosted a massive tournament in the Hero's honor."
"Nobles fretted, but it was a roaring success. Ulstro became known as the land of knights, and the throne solidified. Now it happens every three years—and this is year three."
"Now that you mention it, it rings a bell."
Bilma nodded.
She'd known it only as Ulstro's festival and hid her ignorance of the backstory. She already had a "foolish" image; no need to worsen it.
"Good thing."
"Your first human subordinate isn't an idiot."
"...N-next?!"
She had no idea how to use the tournament but played along and asked for the rest.
"A half-breed winning would draw too much attention at the wrong time. Second place, then enter as a squire."
"Then corrupt the royals. Something like that?"
"Spot on."
Corruption.
Falling from the righteous path to depravity.
Once a word with many meanings, now it meant one thing:
Betraying the continent for the demons.
Whether for material gain, succubus seduction, magical pacts, or overwhelming power—it didn't matter.
"Is that even possible?"
Bilma blurted it out.
Corrupting a queen and her princesses? It sounded absurd. What could they lack to side with demons?
His handsome face wore such confident smugness, it couldn't be a joke.
Handsome? Wait...
She recalled Ulstro was ruled by a queen with two princesses beneath her.
"You're going to seduce them with your looks?"
"Close."
"Come on, even so..."
Bilma waved it off.
He was handsome, sure.
Dark red hair hinting at demon blood couldn't hide it. Any woman might glance twice passing him.
But he looked mid-teens. Not enough to sell a kingdom for.
"I've got this."
"...Eh?"
Her heart suddenly pounded.
Her face burned, her stomach churned. Her eyes locked on his face.
Then she remembered charm magic and lewd tattoos. She'd slept so soundly, she'd forgotten.
"B-but isn't charm magic exclusive to succubi?"
Charm magic was a succubus racial trait. No male succubi existed. Men were the ones to guard against it—or so it was known.
"Right. This is my analyzed imitation. Tricky conditions, weaker than the original. But usable, yeah?"
"...Yes."
"Add lewd tattoos, and it's better than most succubi."
The charm faded, returning her to normal. But her heart still raced.
This guy's a genius.
No one had ever deciphered charm magic. And this boy had.
Humans had excuses—few succubi, demon hostility making samples hard. But as a fellow demon, he'd had prime research material.
Still, the achievement stood tall.
"I handle other schools well too. White magic's my specialty, but I'm versed in black. I helped Irina with her fluid magic. See? Good call contracting with me."
Noticing her expression shift, he grinned brightly.
He was right.
Her doubts vanished. She had no patriotism or love for humanity. She'd contracted with a demon to survive—and pursue magic. With help or not, she'd sell her soul for progress.
"Yes... sincerely."
"Haha, more enthusiastic now. Oh, I never introduced myself. Name's Valdes. Demon Prince, set to become Demon King in two years."
Demon Prince.
Higher status than she'd imagined.
The Demon King died eighteen years ago. Either her son ascended, or the throne was vacant. This boy was his son or grandson.
Top—or second-top—in the Demon Army.
The perfect boss and contractor.
"...Pleased to serve, Lord Valdes."
Hearing Bilma's reply, Valdes looked up, past the dungeon wall, into the distance.
His past party's betrayers—and those who'd joined them—came to mind.
Wait just a little.
"I'll take everything from you."
