Morning broke gently over Kuoh Town, its golden rays spilling through the tall windows of Issei Hyoudou's chamber. Light danced across tangled silken sheets, wrapped around two bodies locked in intimate embrace—where warmth came not just from the sun, but from unbridled desire.
Akeno Himejima straddled Issei with feline grace, her raven hair cascading like midnight silk across flushed skin. Beads of sweat shimmered on her bare body as she moved in slow, reverent rhythm. Her back arched, a quiet gasp escaping her lips—each exhale a whispered offering.
"You're insatiable in the morning, my Lord," she moaned, voice a heady blend of teasing and surrender.
Issei chuckled, his golden eyes half-lidded, hands gripping her hips with practiced control. "Just following orders."
Akeno leaned down, her lips grazing his neck. "And doing it so very well."
The room pulsed with the scent of sex and rising power—an atmosphere thick with both pleasure and purpose. As their bodies neared climax, a chime rang clear in Issei's mind.
[System Notification: New Tasks Acquired.]
[Task One: End Rias Gremory's Engagement with Riser Phenex.]
[Reward: Mutated Evil Pieces – Allows peerage members to evolve into dragons.]
[Task Two: Claim the Two Gremory Sisters.]
[Reward: Destruction Magic (Lucifer Variant) & Familiar Summoning Scroll.]
[Task Three: Assist in Training Rias and Her Peerage.]
[Reward: Personal Training Room — Fusion Type: Danger Chamber (X-Men Protocol + Hyperbolic Time Chamber).]
His smirk faltered. Strategy took root where lust had bloomed.
"Damn system," he muttered. "Where the hell are these tasks coming from?"
[From your King's—Rias Gremory's—deepest desire. She has formally submitted her request to join your harem. She also consulted her elder sister, the Maou Lucifer.]
Akeno, ever perceptive, lazily traced a finger down his chest. "What's the little voice in your head whispering now, Master?"
Issei exhaled. "Rias wants in. And she brought her sister into the loop."
Akeno's violet eyes sparkled. "So, the princess is ready to kneel. About time. She'll make a fine second."
With sudden force, Issei flipped their positions, seizing control. Their pleasure surged—fast, furious, final. When it passed, Akeno lay draped across his chest, completely spent.
"…Also," he muttered, eyes on the ceiling.
[Yes, host?]
"I can't keep calling you 'System' forever. It's getting old."
[Would you like to designate a name for this interface?]
"Yeah. Something fitting." He paused. "Mission Command?"
[Denied. You are not a space pilot, host.]
"…Queen?"
[You already have one in bed with you.]
"Fair. Oracle?"
[A touch dramatic, but acceptable. Still, consider alternatives.]
He sighed. "Fine. Eden. Feels right."
[Accepted. System designation updated to: Eden.]
"Eden, huh?" Akeno murmured. "Sounds divine."
[Speaking of divinity—your Evil Pieces are not standard.]
"…Huh?"
[A surprise awaits. One that will reshape your peerage.]
"Better not mean they turn into furries."
[Unlikely. More like… monsters.]
Issei smirked. "Good."

Later That Morning – Gremory Manor
The Gremory Manor stood like a citadel of nobility and infernal might—crimson towers carved from enchanted marble and adorned with sigils that shimmered like starlight. Inside, the air was perfumed with roses and power, where legacy hung heavy on every wall.
In a sunlit drawing room, two red-haired women sat opposite each other—sisters, yet so vastly different.
Sirzaria Lucifer, the current Maou, bore a striking resemblance to her mother, Venelana Gremory. Her long crimson hair cascaded in thick, commanding waves, and her features were regal: sculpted cheekbones, piercing scarlet eyes, and lips that wore equal parts command and amusement. Her armor gleamed black and gold, shaped to her tall, powerful figure—more queen than warrior, yet both.
Opposite her sat Mio Gremory, the middle sister. Five years older than Rias and far less formal than Sirzaria, Mio's beauty was explosive—voluptuous, wild, and defiant. Her red hair flared like fire, tied back with a dark ribbon, and her violet eyes sparkled with curiosity. She wore a sleek bodysuit with a crimson half-cape—less militaristic than her elder sister, more provocative, more battle-ready.
Rias, by contrast, sat stiffly, her beauty more youthful and unsure. Her sapphire eyes darted between her sisters, seeking guidance.
"You're serious?" Rias asked, voice trembling. "You both support this? Me becoming… his?"
Sirzaria leaned forward, her gaze both comforting and commanding. "Rias… I've seen many devils rise to power. But Issei is something else entirely. He's not just strong—he's destined. Dragons don't kneel to kings. They become them."
Mio smirked, swirling wine in her glass. "Honestly, I thought you'd choose a weaker man. But Issei? He's dangerously fun. I approve."
Rias swallowed. "But it's a harem. Isn't it wrong to just… give myself away?"
"You're not giving anything away," Sirzaria replied. "You're choosing. And in choosing Issei, you're aligning with someone who could change the Underworld itself. Do you want to fight beside him? Or be left behind?"
Rias looked down. "He's different. He doesn't chase me. He doesn't need me…"
"And that's why you want him," Sirzaria said, smiling. "Tell him the truth. About your engagement. About your wish to be his. And when the time comes, let him meet me. I want to see what kind of dragon dares to charm my sweet little sisters."
Mio leaned in with a predatory grin. "I might want a turn too, Riri."
"Mio!" Rias blushed furiously.
Sirzaria only laughed. "Let's see if he survives you first."
Later That Morning – Rias's Private Room
Golden light filtered through gauzy curtains, painting Rias Gremory's chamber in hues of warmth and longing. She lay atop her bed still in uniform—blouse crisp, skirt immaculate, crimson jacket unfastened. Yet her expression was anything but composed.
A soft knock.
"Come in," she called.
Akeno stepped inside with quiet grace. Her uniform was once again pristine, but the morning's glow lingered in her cheeks and the satisfied gleam in her eyes.
"You've been quiet since the meeting," Akeno noted, settling beside her.
"I've been thinking," Rias replied. "About you. About him."
Akeno smiled faintly. "Yes—it happened. Yes—I was his first."
Rias turned toward her, sapphire eyes uncertain. "And you don't feel… guilty?"
"Only if I had lied," Akeno said gently. "But I didn't. You always knew. You were just waiting for permission—from yourself."
Rias exhaled. "I was. I wanted him to chase me. To prove I mattered."
"And instead," Akeno whispered, brushing her fingers through Rias's crimson hair, "he's becoming the one we fight for."
"What does it feel like?" Rias asked. "Being his?"
Akeno's voice softened. "Like standing in the heart of a storm. He's wild, powerful… overwhelming. But I've never felt safer."
Rias sat up slowly. "He'll change us."
"He already has."
Silence. Fragile, intimate.
Then Rias laughed quietly. "Don't be smug when it's my turn."
"I'm always smug," Akeno teased, kissing her friend's cheek. "But I'll try."
"No, you won't."
"True."
Akeno rose, adjusting her collar with flair. "So, when's the confession? Tonight? Chemistry class? Over a Bunsen burner?"
"Akeno!"
She smirked. "Pounce soon. Fewer rivals to stab."
"You're impossible."
"And you," Akeno called as she exited, "are in love with a dragon."

Later That Day – Kuoh Academy
As the afternoon sun dipped low, Issei and Akeno walked side by side under golden skies. Behind them, Rias followed—regal as ever, but her eyes betrayed the weight she carried.
"So, how do you want to handle Rias?" Akeno asked casually.
"Directly," Issei said. "She'll come to me tonight. But before that—we talk about Asia."
"The nun girl?" Akeno's tone darkened.
"She has Twilight Healing. Raynare's watching her. We move tonight, or she dies."
"Then we act tonight," Akeno said. "You'll make her Rais Bishop?"
Issei nodded. "She's worth it."
Akeno considered. "Rias should know. Framing this as 'balance maintenance' might ease things."
"One more thing," Issei added. "Do you think Rias could build me a forge?"
"A forge?" Akeno blinked, then laughed. "You're smithing now?"
"After the duel with Kiba, I gained blacksmithing knowledge. I want to make my own gear. Maybe gifts."
"She'd build you a mountain if you asked shirtless," Akeno smirked. "So yes."

Nightfall – Occult Research Club
Twilight stained the sky in streaks of blood and amethyst. The ORC's summoning circle pulsed gently beneath flickering candlelight.
Rias stood alone before it, nerves tangled in every breath. Her hands trembled. Her heart thundered.
The door creaked.
Issei entered, followed by Akeno, who took her place along the wall with a smirk.
"Rias," Issei said.
"Issei," she replied softly. Her gaze flicked to Akeno, who gave a nod and stepped aside.
"I've made my decision," Rias said, voice low. "I want to join your harem. If… you'll have me."
Issei stepped forward, gold eyes gleaming. "You've always been mine. You just had to accept it."
Tears welled. "I want this… but I need to be free. The engagement…"
"Riser," Issei growled.
Rias nodded. "The Rating Game. Win, and I'm free. Lose…"
"You won't," he said. Firm. Certain.
"You'll fight beside me?"
"Always."
She moved closer. "Then help me. Not just with Riser. With everything. I want to belong to you… but also stand beside you."
He cupped her cheek. "Then start now. We've got someone to save."
"Asia," Rias breathed. "She's in danger?"
"We move tonight," Issei said. "Raynare's closing in."
"Then we go together," Rias agreed. "And Asia… you want her as your Bishop?"
"She deserves strength. And safety. My dear king, I want her as yours"
"She'll have both."
Akeno stepped forward. "You sound like his Queen already, Rias."
Rias looked at her best friend. "Not yet. But I will be."
[Eden Log Updated.]
[Task Confirmed: Rescue Asia Argento.]
[Optional Objective: Eliminate Raynare.]
[Bonus Reward: Divine Dragon Scale – First Layer Unlocked.]
[Warning: Host entering divine conflict zone. Radiant and demonic energies will clash. Recommendation: Prepare emotionally aligned party.]
"I'll need all of you with me," Issei said aloud.
"You have us," Akeno replied, lightning sparking at her fingertips. "Let's give those fallen a night to remember."
"Rias," Issei added, eyes locking with hers. "When this is over—when you're free—I want to mark you. Like I did Akeno."
Her blush deepened, but she stood tall. "Win with me first. Then… everything I am is yours."
