As if overcome with emotion, Sona suddenly hugged him.
"Wha—!?"
The unexpected contact left Kazuki stunned. He looked around for help, but the reactions varied—some were shocked, some were pissed, and others seemed highly entertained.
Sona was much more delicate than Rias or the others—if he hugged her too tightly, she might actually break. And unlike Rias's seductive fragrance, she carried a refreshing scent, like cool mint.
"Hey! Sona! Just how long do you plan on clinging to Kazuki?!"
And just like that, Rias's thunder struck.
As if finally realizing what she was doing, Sona jolted and quickly pulled away.
"Hyaaah!? S-Sorry, Fuwa-kun!!"
Her face was burning red, a stark contrast to her usual composed demeanor. The flustered expression, so unlike her usual cool attitude, made her look unbelievably cute.
"S-Sorry. I'm sure it didn't feel good to have someone like me hugging you… I mean, unlike Rias, I'm… small in a lot of ways, ahaha…"
Sona let out a self-deprecating laugh, clearly comparing herself to her more "endowed" peers.
Kazuki frowned. 'She seriously didn't realize how attractive she is? That is just a damn shame.'
Leaning in, he whispered into her ear.
"Yeah, the size difference was there… but your skin was so soft, and you smelled incredible. Honestly? It felt really good."
"!!!??"
The moment those words left his mouth, Sona's entire face turned crimson—even her ears were red.
With a startled yelp, she jumped away from him, trembling uncontrollably.
"W-Wha…!? S-Soft… smelled good… w-wait… hyaahh—!!"
Her words spiraled into incoherence before she wobbled, her eyes rolling back.
Just as she was about to collapse, Kazuki caught her. But by then, she was already out cold.
"President?! Hey, are you okay?!"
Before he could do anything, Saji appeared, snatching Sona from his arms.
"Oi! What the hell did you do to Kaichou?!"
"I just whispered a compliment—"
"You whispered?! What the hell were you whispering to her?! Damn it, I'll take her to the infirmary!!"
With Sona in his arms, Saji bolted down the hallway at full speed.
Kazuki sighed and turned to Yumi.
"Yumi, go after them. If the nurse isn't there, I don't want him being the one to take care of her."
"Got it! I'll be back in a bit." Yumi nodded and quickly followed after Saji.
Rias crossed her arms, letting out a sigh. "Kazuki… Sona has zero immunity to men."
"I messed up, huh?"
Rias nodded silently. 'Yeah, okay, maybe you went too far!!'
However, ever since Kazuki became a devil, he'd been surrounded by beautiful women all the time. It was easy to forget boundaries sometimes.
And then—
"Oh? Where's Sona-chan?" A familiar voice made Kazuki turn.
There stood Serafall Leviathan, now fully changed.
"Whoa…"
He couldn't help but let out a sound of admiration.
Gone was the childish, magical girl aesthetic. Instead, she wore a navy-blue knee-length suit, tailored perfectly to her body. Her twin tails had been undone, letting her silky black hair flow down her back in a sleek, straight style. A touch of light makeup enhanced her already striking features.
She looked elegant. Refined. Gorgeous.
No one would ever believe that this was the same woman prancing around like a magical girl earlier.
"Well? How do I look?"
"You look stunning, Leviathan-sama!! Truly beautiful. If someone told me you were Sona's older sister, I don't think anyone would doubt it."
Serafall's lips curled into a shy smile.
"Really? Ehehe… That makes me happy."
Her bashful reaction was too cute, and Kazuki felt his heart skip a beat. To cover up his momentary lapse, he turned to Shinra and gave her a thumbs-up.
"Shinra-san, good job."
She nodded and returned the gesture.
Then, Serafall tilted her head, looking up at him with curious eyes.
"Hey, you… Can you tell me your name?"
Kazuki immediately dropped to one knee, bowing in proper etiquette as he introduced himself and apologized for his earlier disrespect.
"I apologize for my rudeness earlier. My name is Kazuki Fuwa, a [Pawn] in Rias Gremory's peerage. I did not mean any offense, Leviathan-sama."
"Fuwa Kazuki…? Ohh, so you're the rumored 'Guyver' everyone keeps talking about."
Hearing that she already knew about him, Kazuki felt both honored and tense.
"I am truly honored that you've heard of me, Leviathan-sama. However, what happened earlier was entirely my own fault. I will accept any punishment, but please do not hold Rias or my fellow peerage members responsible."
What he did was something that could have easily been considered disrespectful, even if Sona had forgiven him. Depending on how this played out, a lesser man might have been executed for it. That's why he was ready to take full responsibility, ensuring that Rias and the others wouldn't suffer for his mistake.
But then—
"You can relax, Kazuki-kun!! This is just a private moment, and I was getting a little carried away myself."
Serafall smiled gently, her cheeks lightly dusted with pink.
"So of course, I won't be punishing you, or your master and her peerage. Besides… you were the first person to ever scold me like that. It was kinda… nice."
Her soft smile and faint blush made her look criminally cute.
Kazuki exhaled in relief.
"Thank you, Leviathan-sama."
But the moment he said that, Serafall suddenly puffed her cheeks in mild frustration.
"Hmm… I don't really like being called that."
Her lips curved into a playful pout before she leaned in, eyes sparkling mischievously.
"Hey, Kazuki-kun, what do you call Sirzechs?"
The sudden use of his name caught him off guard. Hearing it from Serafall with that innocent smile made it hard to even argue.
"Uh… normally, I call him 'Maou-sama' or 'Sirzechs-sama.'"
The moment he said that—
"No, no, no! That's not good enough, Kazuki-kun! You should call me Big Bro-in-Law! Or just Big Bro!"
"Absolutely not." Kazuki rejected instantly.
This was the same guy who had nearly obliterated him earlier, and after seeing how much of a dumbass he could be, Kazuki had no intention of getting any closer to Sirzechs than necessary.
"Then… then how about calling me 'Sera-Oneechan'?"
"That's…"
He had no idea how she thought that was a reasonable alternative, but it was way too much. He opened his mouth to refuse, but—
"Is that a no?" Serafall's big, pleading eyes locked onto his.
"Sera-nee-san, then."
"Yay! It's decided!"
'Fuck.' He'd fallen for it.
Serafall's 'Is that a no?' attack had been too much.
She was a Maou, and yet she had the face of an innocent girl begging for affection. He didn't stand a chance.
Kazuki sighed, already feeling the weight of his defeat.
Rias, meanwhile, crossed her arms and glared at him, her expression ice cold.
"Kazuki… seriously?"
'Yeah, I'm feeling it.' The chilly gazes from Rias and the others were piercing into him.
'But what was I supposed to do?!'
At times like this, he recalled the words of a great historical figure:
"Cute is justice."
Just as Kazuki was mentally preparing to accept his fate—
Ding-dong, ding-dong!
The school bell rang, signaling the start of the next class.
"Oh no! Class is about to start!"
Issei quickly bowed to the Devil Lords and bolted, prompting the other second-years to follow his lead and rush up to the third floor, where their classrooms were.
Kazuki took the opportunity to escape, sprinting toward his own classroom.
"Ah! Kazuki, wait up—!"
Rias called out to stop him, but he ignored her and kept running.
"Do your best, Kazu-kun~~☆"
Serafall—no, Sera-nee-san—cheered him on in a bubbly voice as he dashed toward class.
"…Well, they've all gone now."
As the students returned to their classrooms, the courtyard fell quiet.
Now, the only ones left were Sirzechs, his father, Grayfia, and Serafall.
"So, Serafall. What exactly was that all about?" Sirzechs spoke up, his expression unreadable.
"Hm? What do you mean?" Serafall tilted her head cutely, playing dumb.
Unfortunately for her, Sirzechs wasn't Kazuki—he had known her for far too long to fall for her innocent act.
"Obviously, I'm talking about that whole 'Onee-chan' thing."
Kazuki was Rias's Pawn, her servant, and—though unofficial—her fiancé. Yet Serafall had just forced him to call her 'big sister.' From an outsider's perspective, it could easily look like Kazuki had chosen Sona over Rias.
"Hmmm, I didn't really mean anything by it~? I just thought… having a cute little sister like Sona-chan is great and all, but having a cheeky yet kind little brother like Kazu-kun might be fun too☆"
Serafall winked playfully, unfazed by his scrutiny.
"Besides, Oji-sama hasn't even officially approved Rias-chan's engagement to Kazuki yet, right? So technically, nothing's set in stone. If Sona-chan happens to get close to Kazu-kun in the meantime, there shouldn't be a problem, right?~ And from the looks of it… he is interested in her."
Serafall turned toward the doorway, where three figures had just arrived.
Sona. Saji. And Yumi.
It looked like they had returned from the infirmary.
"W-W-W-Wait… Me and Fuwa-kun…?" Sona stammered, her face instantly turning bright red.
It seemed like she had imagined the scenario in her head.
Saji was standing there, frozen in shock at hearing his master's older sister say such a thing. Meanwhile, Yumi puffed out her cheeks in obvious displeasure.
"Well, you never know how relationships between men and women might change~" Serafall giggled, then smirked mischievously.
"…And if it comes down to it, I wouldn't mind being his partner either, you know? "
Her teasing words and flirtatious gestures left Sirzechs sighing as he rubbed his forehead. 'This is going to be a mess.'
His father chuckled awkwardly, beads of sweat forming on his forehead.
Honestly, this was all his fault for not officially approving Rias and Kazuki's engagement yet. Now Serafall was taking full advantage of the situation.
'And if Mother found out about this… well!' Sirzechs wanted no part in that fallout.
For now, he could only pray that Rias would do whatever it took to properly secure Kazuki for herself.
'Good luck, Ri-tan.'
—
A week had passed since that chaotic and troublesome school visit.
—
After the event, Sirzechs and the others had a chance meeting with Issei's parents, and for some reason, they hit it off instantly. Before anyone could stop it, they had been invited to the Hyoudou residence.
Realizing the potential disaster that could unfold, Rias had no choice but to accompany them. However, when she returned home late at night, she looked completely drained, as if her very soul had been sucked out.
When Kazuki asked her what had happened, she whispered in a lifeless voice:
"I've never been more humiliated in my entire life…"
'What the hell did that damn Maou do?!'
It took a ridiculous amount of effort to revive the burned-out Rias. Kazuki had to soothe her, pamper her, and, in the end, fuck her brains out until she was satisfied.
Meanwhile, Serafall and Sona left together in a seemingly good mood. As they parted ways, Serafall flashed Kazuki a teasing smile.
"I'll be back soon, Kazu-kun~♪" she sang.
Sona, on the other hand, had been sneaking glances at Kazuki all night, her face flushed red. The sight of her bashful expression stuck with him.
