Chapter 475 Stuck in the Bull’s Horn
Edited by: Kanaa-senpai
After confirming that Koneko had become Aki’s cat — and that her power had skyrocketed as a result, her Bloodline fully awakened and controlled without going berserk — Kuroka’s feelings became deeply conflicted. She never again raised the issue of taking her sister away.
Though Kuroka gave up on reclaiming Koneko, she still refused her sister’s request to stay. She believed that the two of them carried a bloodline of warriors in their veins, and that only a group like Khaos Brigade could offer them the right path. If they surrendered to a peaceful life, they would kill their friends and family when their power inevitably ran wild, and regret would come too late.
But Koneko hadn’t gone berserk. She’d mastered her Bloodline even better than Kuroka had.
Torn, Kuroka returned to Khaos Brigade with her thoughts in turmoil, continuing her plan to capture Fenrir. Of course, the fact that the cat-eared loli hadn’t stopped her at all made the departure effortless.
No matter how Kuroka’s mindset shifted, this encounter had finally let Koneko move on. If Kuroka wanted to stay, there was still the old incident to clear up — that would be its own headache. Since she wanted to remain with Vali, let her go.
With that thought, Aki stopped worrying about the situation.
Three days later, while serving as a mascot in the Student Council Room, Shinra Tsubaki came to find him.
”Aki, President sent me to get you.”
Sona Sitri’s injury hadn’t been made public. Aside from the few of us present that day, even Kusakabe Reiya and the rest of her Peerage didn’t know.
Seeing Shinra Tsubaki arrive, they asked curiously, “Vice President, where’s President? She hasn’t been to class in days.”
”She’s been busy handling family matters.”
Once they were out of earshot of the Student Council members, Aki asked, “What’s the sudden summons? Did President’s condition worsen?”
”No, President’s already healed.” Shinra Tsubaki shook her head. “Between healing magic and the phoenix tears we gathered later, President made a full recovery yesterday.”
Aki frowned. “Then why…”
”You’ll understand when you see her.”
They used a Transport Magic Circle to reach the Sitri family’s territory in the Underworld.
The buildings before them were no less grand than the Gremory estate. Inside the central villa’s main building, the decor, the number of servants, and the quality of their service were all top-tier.
Accompanied by Shinra Tsubaki, Aki arrived at Sona Sitri’s door.
Knock, knock.
Shinra Tsubaki announced respectfully, “President, Lady Serafall, I’ve brought him.”
After receiving a reply, she bowed slightly and withdrew. Before leaving, she gave Aki a meaningful look.
He saw it. He didn’t understand it.
Why not just message him through the Soul Network? What was with the cloak and dagger?
He didn’t have long to stew over it. The moment Shinra Tsubaki left, the door swung open.
Serafall — with her twintails, cute outfit, and smoking body — yanked him inside.
”Aki-chan, finally here!” Serafall blinked her big eyes, looking pitiful. “Please, help me talk some sense into little Sona! She worked so hard, right? The enemy was just too strong! How can she blame herself?”
”Huh?”
Aki blinked, pressing for details. The story came out:
After the battle with Loki, Sona Sitri’s mindset had fallen apart. Of the seven girls, she’d been the weakest. She’d been the one who held everyone back. In the end, she’d become the entry point for the forced breakthrough, forcing Aki to push through, nearly triggering Ragnarok.
Even if Aki hadn’t broken through, Serafall would have fought Loki anyway — the outcome would have been the same. Aki was confident he could have ended Loki in one blow, but neither Sona nor anyone else shared that confidence. If that one shot had missed, the Three Realms would already be in chaos.
So even though Aki had tried to reassure her, Sona still sat there with her knees drawn to her chest, face buried, not moving at all.
Serafall had been trying to comfort her for a long time before Aki arrived. All the rational points were clear to Sona, but she was stuck in the bull’s horn — spiraling inward.
Aki tried a couple of lines. He gave up fast.
Some people you can’t talk out of something. The worst type isn’t the one who doesn’t understand — it’s the one who understands perfectly but still can’t let go. And when this happened to someone like Sona, the most calm and rational person you’d ever meet, it was almost impossible to solve.
”Serafall…”
”If you’d like, you can call me big sister, just like Sona does.”
Though worried sick, she knew she couldn’t add pressure. Serafall forced her usual cheerful demeanor.
”Alright. Big Sis Sera.”
Just calling her “Sister” felt strange. Adding the name made it better.
”I think President’s issue is simply that her power has fallen behind — way behind Rias and the others. Comforting won’t fix that.”
As Aki spoke, Sona, who had been frozen, visibly flinched.
Why had she gotten stuck in this bull’s horn? A big part was that everyone had been at roughly the same level before. Now, her own Queen, Shinra Tsubaki, had broken through to Demon King class, completely outstripping her in every way. Before the Loki incident, she hadn’t realized the gap — she’d just thought she’d catch up with more cultivation. But the battle made the distance real, undeniable.
To put it bluntly: if things kept going like this, she wouldn’t even qualify to stand beside Rias and the other girls.
In truth, Sona Sitri’s strength was far from low. She hadn’t even come of age yet. Once she reached adulthood and started Rating Games, she’d easily crack the top ten — maybe even the top five.
But the human mind feared comparison.
In the Loki battle, all seven girls were roughly the same age, but Sona’s power had fallen dramatically below the others. Rossweisse wasn’t yet Demon King class either, but her combat instincts were sharp, and her knowledge of Loki’s abilities let her perform far better.
A Valkyrie who couldn’t fight wouldn’t deserve the name.
More importantly, compared to her own older sister Serafall, Sona looked even worse. Serafall wasn’t as strong as Sirzechs, but she was still one of the Underworld’s top fighters. Otherwise, she wouldn’t hold the title of Leviathan Demon King.
Sona hadn’t been born that much later than Serafall, yet the power gap between them was huge. Rias was in the same boat — her older brother had already become a Demon King, so her family had fallen to her. The same was true for Sona.
Sona’s reaction didn’t escape Serafall. It made her feel helpless.
She thought her little sister was already amazing — in strength and everything else. Even if Sona was a bit weaker, Serafall could protect her. But saying that now wouldn’t help.
Serafall looked at her sister, stuck in her own spiral, and said quietly, “Sona… get some rest. I’ll come visit again tomorrow evening.”
She didn’t handle many matters personally, but being a Demon King meant she couldn’t stay at home forever.
Serafall left. Aki was about to say his goodbyes too. The sky was getting dark. Even though they had a Master-Servant relationship, staying alone in a bedroom together after dark… it didn’t feel right.
Well, mostly, Aki was worried about what he might do.
”I’ll take my leave too, President…”
Slap!
Before he could finish, Sona was suddenly beside him, gripping his wrist.
”President?”
Looking at the black-haired girl with glasses, her eyes rimmed red, her lips pressed tight in a fragile expression, Aki’s heartbeat quickened.
Was it really what he’d been thinking?
Once he’d realized the root of Sona’s spiral was her lack of power, this possibility had crossed his mind. But Serafall was there, and it felt a bit like taking advantage…
Sona stared at him for a long moment, then slowly released her grip.
”Aki, I’m still your Master, aren’t I?”
”Yes…”
Aki looked at Sona’s slender figure wrapped in her pajamas and forced himself not to peek down her collar. Her emotions were unstable. Misreading this would be disaster.
Of course, if it was what he thought, then everything would be simple.
Sona didn’t leave him wondering for long. She wasn’t the type to agonize over decisions. Once she’d made up her mind, there was no hesitation.
If Rias could do it, if Shinra Tsubaki could do it, if so many others could do it, why couldn’t she? She knew her feelings for Aki weren’t at that level yet, but feelings could grow.
But if she didn’t act now — forget her dream of building a school where even lower-class Devils could study — she’d be left so far behind that she’d lose sight of everyone around her.
”Aki, I’m ordering you now, as your Master.”
Sona returned to her usual calm. She knelt on the bed, her eyes fixed on Aki through her glasses.
”Dual Cultivate with me. Now. Raise my power.”
Looking at the black-haired schoolgirl whose eyes were still swollen from crying, Aki smiled. No more words were needed. Just one answer.
”As you command, President.”
The moment he said it, a flash of magical light sealed the door shut. The curtain that had been slightly drawn also snapped closed.
The bedroom, filled with a girl’s sweet fragrance, became their private space. Feeling the sudden stillness and charged atmosphere, Sona — who had never been physical with a man — instinctively tensed.
The delicate, pale toes curling beneath her pajama leg, like silkworm cocoons. Her eyes drifting away, avoiding his.
Seeing the always-calm-and-rational President behave so adorably made Aki feel a little mischievous. He wanted to tease her.
But considering her mental state, he held back.
There would be plenty of time to play fun games with his dear President later. For now, he needed to focus on business.
Aki smiled warmly and moved closer to the black-haired girl on the bed. She just turned her head further away, as if that could make her shyness disappear.
Even though Sona wasn’t taking the initiative, her posture was practically an invitation. Facing her like this, Aki had no self-control left to even try.
He lunged like a tiger at its prey, onto the bed, pinning Sona beneath him.
Hot, hard Little Aki pressed against Sona’s thin pajamas and her bare shoulder. Through the loose neckline of her sleepwear, her small, delicate, yet firm white breasts peeked out — pale and clean, trembling with his movements.
Every time he looked, it struck him anew. So beautiful it was breathtaking.
Aki reached for her pink sleep set. The shy President still kept her eyes shut, but her slim arms and long, straight legs obediently lifted, parting for him.
Without clothes, Sona’s pale, perfect, youthful body seemed to glow under the light, radiating stunning allure.
Looking at her slender but beautifully proportioned figure, Aki could only marvel.
But even as he admired her in his mind, the insistent desire between his legs kept telling him the same thing: he didn’t want to just kiss or touch this exquisite face. He wanted to conquer her, right now.
Deep blue Mana glimmered. Little Aki — already more than ready — sprang free.
Aki gripped Sona’s breasts, perfectly sized for one hand, watching as the soft, round peaks pressed together to form a long, thin line. Only then, satisfied, did he slowly slide Little Aki between them.
”Haaah…”
A sharp exhale. Aki’s body trembled as he panted, as if he could barely contain the overwhelming stimulation. Eyes closed, savoring an ecstasy beyond ordinary experience, he began to move.
Rocking his hips, he pressed his full weight into the act of claiming that tempting body. Sona’s pale cheeks slowly flushed, and faint gasps began to slip from her lips, never stopping, matching his rhythm.
Feeling the tight slide of her soft breasts around his shaft, Aki panted and reached his other hand down, brushing against Sona’s tender garden.
Under his attack from both sides, Sona made no sound — but her body responded, slick and ready. The soft, untouched garden slowly wrapped around Aki’s fingers, hotter inside than out, as if it craved him.
The delicate flesh writhed, trying to keep his fingers inside to soothe the burning inside her.
Aki explored, searching her soft little garden for the weak spots, one after another. His skilled fingers found a patch of inner wall and pressed just slightly — and the girl beneath him let out a sultry cry.
Her walls clamped down on his fingers, as if all the desire in her body was being ignited by his touch.
Juice. Flooded.
So much — like losing control — soaking through the sheets, coating the dry fabric in thick, slick fluid.
Looking down at Sona, quiet as if she were asleep, Aki could barely contain his excitement. He released it all on her body without restraint. His movements grew wilder, harder to stop.
Pounding. Driving her soft breast flesh together, kneading those full, elastic peaks. The hot, thick head of Little Aki repeatedly struck deep into the valley between her breasts as he ground against her.
Aki gritted his teeth. The wave of desire was overwhelming. He drove into those round, soft mounds again and again, mindlessly.
”Gnn… it’s terrifying… I’m supposed to be the one in charge… so why do I feel like I’m being devoured…”
Feeling Aki moving on top of her, Sona thought dazedly.
For his first time being this close with President, Aki refused to hold back, gritting his teeth and thrusting into her chest without restraint. The soft mounds scraped and squeezed against his sensitive glans.
Compared to big breasts, these — just the right size to fit in one hand, needing to be squeezed together to use — offered a tighter, more focused pleasure.
The mounting pressure made Little Aki pulse violently. Aki was gasping now, close to spilling.
”Nngh…!”
With one last hard forward thrust, Aki’s body shuddered. The urge he’d been holding back finally burst through his control.
A flood of Life Essence filled Sona’s cleavage instantly; white fluid spilled from the sides of her body.
Panting, he slowly pulled Little Aki out. A bridge of white Life Essence stretched from one breast to the other across her valley, trembling with each breath Sona took, her flushed face making the sight even more enticing.
It was almost unfair…
Still gasping, Aki felt himself harden again without even a pause.
He wrapped his arms around Sona from above. Little Aki was already lined up at her garden’s entrance, rubbing slowly.
”President. Time to raise your power.”
Even with his mind practically drowning in desire, he still remembered his real purpose.
Looking at Sona’s flushed face beneath him, he cast aside every stray thought and thrust forward.
Little Aki drove deep into Sona’s tight, warm virgin garden. The moment he entered, a wave of pure exhilaration hit Aki.
An intense, unexpected grip clutched him from inside — nothing like her cold, rational surface. Countless tiny mouths seemed to greedily suck at Little Aki, making him gasp, desperate to keep himself under control.
But then, seeing Sona’s brow furrowed, her expression set with resolve, Aki clenched his jaw and pushed through, piercing the girl’s Purity Symbol, driving deeper into the wet, narrow passage inside.
”Nghh! It… it hurts… so this is the pain Rias and Tsubaki went through to get stronger?”
Thin traces of red dripped from Sona’s smooth, pale garden, flowing down her white thighs and blooming like plum blossoms on the sheets.
It was pain. But she felt it was right.
If you wanted to get stronger fast, you had to pay something.
