Chapter 106 Six and Nine*
Edited by: Kanaa-senpai
Aki recounted the previous night’s chaos—the Mountain Demon’s subjugation, the Fallen Angel Raynare’s schemes, and his own emergence as a Stray Devil Form¹—all while Rias used her stunning legs, delicate hands, and heavy breasts to stimulate “Little Aki.”
He didn’t hold back his plans for Amano Yuuma; despite her twisted personality, her utility was high. He figured that if he could keep her from going off the rails and provide a little “hands-on discipline,” she’d make a reliable pawn.
Rias, for her part, couldn’t have cared less about the monsters or the Fallen. The Mountain Demon was just another target on a list she’d already vetted, and she’d never doubted Aki’s ability to crush it.
As the one in charge of Kuoh Town, she was well aware of the outside players moving through her territory. She knew they were up to something, but as long as they didn’t touch her people or the local civilians, she was content to let them play their little games.
It was Aki’s new form that truly held her attention. After having him manifest his Stray Devil wings, she spent several minutes tracing the ink-black feathers before curiously seizing his thick, whip-like tail.
”If you didn’t lack the horns, I’d swear you were a stray remnant of the Ancient Devils²,” Rias mused.
”Ancient Devils?” Aki asked. (Great, another term I’ve never heard of.)
The crimson-haired heiress didn’t answer immediately. Instead, she shifted her body into a series of provocative poses, using every inch of her skin to worship his “Great Dragon.” Between sharp, hitching breaths, she began to weave the history of the Ancients and the evolution of Mana. Aki didn’t let the distraction of “Little Aki’s” constant activity keep him from absorbing every word from “Professor Rias.”
The Ancient Devils were the primordial stock, tracing their lineage back to the very dawn of the world. Before the clean distinctions of Demons, Gods, and Dragons, the world was a battlefield for three massive factions: the Devils of Hell, the Celestial Gods of Heaven, and the Human Alliance.
It was a war of total attrition. To keep their armies from vanishing, both the Devils and the Gods began breeding subordinates—the modern Demon and Angel races were born from that desperate need for cannon fodder.
Time eventually ground the original Ancients and Celestials into dust, and the Human Alliance fractured into the world we know today. The modern races rose from the ruins, inheriting the old blood-feuds.
It wasn’t until ten thousand years ago, when the Dragons and other human-realm powers grew too strong to ignore, that the two sides finally called a truce. While the Seventy-Two Pure-blood families were proud, they were just a shadow of the true Ancient Devils who had long since vanished.
As the Gremory heir, Rias’s blood was as pure as it got, but she only possessed the wings—a mere 33.3% of the true Devil phenotype. Aki, however, had the tail and the wings of a primitive.
Rias suspected he carried a dormant “Ancient Devil” gene—not a full bloodline, but a genetic echo—that had finally been triggered by the Evil Pieces³.
Aki didn’t bother correcting her. He knew the Evil Pieces were just a catalyst; the real heavy lifting came from his Dual Cultivation⁴. Still, as long as it wasn’t a problem, he didn’t care what she called it. While a true Ancient might be a threat, a modern Demon with a trace of “noble” ancient genes was actually a status symbol among the aristocracy. It was a “high-tier mixed-blood” status that could rival the prestige of the current Pure-bloods.
The conversation eventually shifted to the synergy between Qi and Mana. Once a practitioner “Breached A-rank” in one discipline, the evolution of their very soul would naturally drag the other along for the ride. Even without specialized Magic Power Extraction⁵, Aki was on a slow, inevitable path to becoming a Mid-Rank Mage.
As Rias finished her explanation, the tension in the room hit a breaking point. Aki lay back on the floor and pulled Rias over him in a reversed “six-and-nine” position.
He spread her porcelain-white thighs, his tongue exploring the slick, quivering folds of her “Flower Valley.” Rias, draped over his legs with her full breasts pressed flat against his skin, let out a sharp cry before closing her lips around the throbbing “Red Dragon.”
”Mgh… nnh… mmmph…”
Even with her mouth stretched wide, she could only take in a fraction of him before he hit the back of her throat. Without mastering the art of deep-throating, swallowing “Little Aki” whole was an impossible task.
They traded pleasure in a rhythmic, desperate heat. Feeling her floral path begin to spasm as she hit her limit, Aki stopped holding back. He thrust his hips upward, pressing against her tongue as he unleashed a massive, scalding flood of essence.
With her mouth full, Rias tried to swallow the thick, white cream, but there was simply too much. She choked and coughed, the excess spilling from the corners of her mouth and even trickling from her nose as the climax tore through them both.
Once the fire burned out, they spent a few more minutes in the bathroom, washing away the evidence of their “extra-curricular activities.” When they finally stepped out, they were greeted by Akeno and Koneko. Both girls were beet-red, their eyes darting between Aki and Rias with palpable jealousy. The bathroom’s soundproofing was non-existent; Rias’s uninhibited moans had clearly left the two girls outside wet and wanting.
Rias smoothed her hair, putting on her best professional facade. “Alright, you two. Go get washed up. We have class.”
”My, my… and whose fault is it that we’re running so late?” Akeno said.
Rias shot her a warning glare. “Just go!”
”Yes, yes, President~”

”Aki, here. This uniform is custom-made for your measurements. I didn’t give it to you before because of the wings, but it’s perfect now.” Rias pulled a fresh set from the wardrobe.
Since they’d already shared everything, Aki didn’t hesitate to strip and change right there. Standing before the mirror, he felt a bit restricted—and not just because he was “going commando.” The suit felt tight across his shoulders.
Rias noticed, stepping in to adjust the collar. “That’s strange. You’ve grown, Aki. I had these measured right before summer break. I’ll have to order you a bigger size.”
Aki paused. He’d checked his height just two days ago and he’d been 170cm. But standing next to the 172cm Rias, he realized they were now eye-to-eye.
He realized what was happening. His physical growth had been suppressed by the Cuckold Template⁶ he’d been forced into. Now that he had reached A-rank and begun to reclaim his life, his body was finally catching up to his true potential. He was finally growing out of the “loser” role he’d been scripted to play.

Long black hair, crystalline earlobes, and pitch-black feathered wings betray her true nature, concealed beneath a pale pink dress or a revealing black leather outfit. Initially appearing pure and innocent, she reveals a submissive, obsessive side during combat and intimacy—becoming Aki’s devoted slave, her defiant warrior spirit melting into yielding ecstasy as her body remembers the sensations of Dual Cultivation.
