Not far from there, Grayfia, Sona Shitori, and Tsubaki Shinra stood calmly.
Sona, with her signature glasses, looked neat in her Kuoh Academy school uniform.
Her black hair was styled in a short bob, her body slender, and her purple eyes reflected the seriousness that had become her trademark.
Next to her, Tsubaki stood gracefully. Her long, straight hair fell all the way to her knees, with bangs neatly parted across her forehead.
Tsubaki also wore glasses, but what stood out most were her heterochromatic eyes: the left one purple, the right one light brown, conveying a balance between calm and sharpness.
Both of them watched the human who, just a few days ago, had easily defeated them: Rian Andromeda.
Meanwhile, Grayfia remained completely unfazed by Rian's eccentric antics.
Not because she was unaware, but because… Grayfia had long since given up trying to comprehend the strange existence that was Rian Andromeda.
For her, the main focus was the Rating Game screens, in accordance with her role as official observer and witness of the match.
Even if there was anything strange in the room, she was used to it… especially when it involved Rian.
"Rian…" Sona spoke up, her tone laced with curiosity. "Rias and her peerage seem to be struggling. Aren't you even a little worried?"
Rian removed one of the cucumber slices from his eyes, glanced at the magical hologram screen in front of him, and let out a small sigh.
"Really?" Rian muttered casually. "Tch… Gesper-kun runs so slowly. I'll have Shironeko chase him while carrying some onions later."
The atmosphere in the room suddenly turned strange: silent, as if everyone was holding their breath.
"U-uhh… You're really not worried?"
This time, Tsubaki spoke up, her voice awkward and accompanied by a cold sweat at her temple.
Rian slowly turned toward Tsubaki, replying with a calm, almost arrogant expression.
"Worried… about them?" Rian smirked. "For what? I'm far more worried about my own face."
Sona's eyes widened slowly, her breath heavy. A vein on her temple was faintly visible, a sign that her patience was nearly at its limit.
Her right hand began to rise to shoulder height, as if preparing to launch a high-pressure water spell straight at Rian's face.
Tsubaki, standing beside her, had already taken a half-step back, fully aware of what might happen next.
But before her anger could erupt, Sona restrained herself, taking a deep breath… and exhaling slowly. For some reason, she regretted giving attention to that narcissistic creature.
"…No, it's not worth it," Sona murmured softly, though her body trembled as she struggled to contain her emotions. "Calm down, Sona…"
Meanwhile, Rian remained seated casually, pressing another cucumber slice back onto his eyes.
"Good. Stay calm, Sona-chan. An angry aura can ruin your skin, you know? Not very relevant if you want to be a good wife."
Hearing Rian's words, Sona's patience finally snapped completely.
With a smile that seemed calm but carried hidden anger, Sona turned to Tsubaki and Grayfia.
"Tsubaki, Grayfia-sama," Sona said softly, raising her right hand slowly. "Please… let Rias know that there's been a little… accident here."
Instantly, several blue magic circles appeared in the air, slowly spinning above Rian's head. The atmosphere shifted drastically, like the calm before a storm.
Tsubaki and Grayfia immediately stepped back a few paces. Swiftly, they raised their hands and formed layers of magical barriers, ready to withstand the outburst of the normally composed Student Council President.
"Tidal Wave," Sona said flatly, almost devoid of emotion.
And then, the flood came.
High-pressure water slammed into Rian with incredible force, sweeping across the floor, toppling chairs and walls, drenching bookshelves, and destroying nearly the entire interior of the clubroom.
The water raged in every direction, temporarily filling the room to the brim, turning the elite space into a chaotic swimming pool.
Amid the receding flood and the destruction wrought by Sona's wrath, only one sound could be heard: the laughter of Rian Andromeda.
"Hahaha…"
Even though the room was in shambles and the sofa Rian had been leaning on was destroyed, his uniform remained completely dry, and not a scratch marred his body.
Rian could now activate Infinity passively, thanks to his mastery of the Reverse Cursed Technique.
He had even configured his body, especially his brain—to automatically trigger the technique at regular intervals, maintaining mental clarity and alertness.
The result? Rian could now effortlessly repel any harmful substances around him, including the pressure of Sona's magic water.
Still lying on the floor amidst the wreckage of the sofa, Rian casually removed his facial mask.
But before he could make any of his typical cheeky comments—which he knew Sona, the demoness responsible for the flood, definitely wouldn't want to hear—Sona stepped forward, positioning herself directly above his reclining form.
Her right hand rose, forming a sharp, solid spear of water.
Rian looked up at her, his expression calm yet mischievous.
"Eh? Sona-chan… why do you want to get me wet? And that… water spear? What's it for, if I may ask?"
Sona glared sharply, her aura flaring with an intense blue glow that pulsed like water under pressure, ready to explode at any moment.
"I hope you end up more than just wet, Rian Andromeda," she said coldly. "And as for this spear? Isn't it obvious?"
Rian, as shameless as ever, gave a small smirk and replied with a relaxed tone,
"More than just wet? And that spear...? Don't tell me…" He tilted his head slightly, his smile growing thinner. "Sona-chan's starting to like seeing a handsome man's body exposed? Tsk, tsk… how indecent."
Without another word, Sona thrust the water spear straight toward Rian's chest, mercilessly.
But, as expected, it never truly connected.
The instant the spear's tip neared him, Infinity activated.
The space around Rian warped, and everything slowed down, as if time itself refused to approach him.
An endless sequence of invisible layers split the distance between the spear and Rian's body—an unseen, absolute barrier separating the two.
No matter how much demonic power or pressure Sona poured into her attack, the result remained the same—Rian couldn't be touched.
Grayfia and Tsubaki could only sigh, watching as the human known as Rian Andromeda managed to turn a girl as calm as still water—Sona Sitri—into a raging sea of fury.
On the other hand, Tsubaki couldn't help but recall what had happened a few days earlier, during the sparring session between Rian and Sona's peerage.
Rian had indeed won easily… but that session had gone completely off track.
Instead of fighting seriously from start to finish, Rian had spent most of the match teasing every single member of Sona's peerage—who, unfortunately for them, were all women.
Perfect targets for someone like him.
With his usual flair, Rian delivered sweet lines wrapped in that infuriatingly confident smile and exaggeratedly dramatic gestures straight out of a cheap romance drama.
And yes… even Sona herself hadn't escaped his antics.
What made it worse was that Rian's reputation at school was just as bad. He was infamous for flirting with the female students—
from the shy first-years to even the captain of the martial arts club.
Naturally, this caused countless uproars, most of which ended with Rian being summoned to the Student Council office.
So, if Sona was finally exploding like this… it made perfect sense.
It was perfectly reasonable that today, Sona Sitri genuinely wanted to silence Rian once and for all—and throw him into the open sea without a boat.
"Sona-chan," Rian said softly. "This position… isn't very proper, you know? I'm starting to worry you're getting too used to being on top, not underneath."
His grin turned even more mischievous, laced with shameless teasing.
With slow, deliberate confidence, Rian lifted his right hand and, using only the tip of his index finger, touched Sona's water spear.
The touch was gentle—almost like a caress—yet annoyingly provocative, as if he was doing it purely to mess with her.
"Y-you—!" Sona's face flushed crimson, a mix of fury and embarrassment coloring her expression.
"You know what I mean, don't you, Sona-chan?" Rian interrupted smoothly, his tone still warm and composed. "A beautiful and confident girl like you… should already understand things like this."
"JUST DIE, YOU PERVERT!" Sona finally shouted, her voice sharp and trembling with rage.
Her demonic aura surged violently, shimmering like heatwaves, the air around her rippling with raw energy.
Rian, however, remained lying calmly on the floor—unfazed, unshaken, and still smiling as if he were simply greeting the girl next door.
It was a smile far too friendly for a situation that could easily turn lethal.
A few moments later, the absurd incident came to its inevitable conclusion: Sona Sitri was, officially, frustrated beyond words.
Expression blank but clearly seething, she turned on her heel and walked out of the ruined room—devastated by her own spell… and, of course, by Rian's relentless provocation.
