"Big bro! You secretly brought that E-cup woman to the infirmary behind my back!?"
As she entered the lounge, Yuki dramatically struck a heartbroken pose, glaring at Kuzeha with exaggerated indignation.
"What do you mean secretly? And is the infirmary supposed to be some kind of shady place?" Kuzeha asked helplessly.
"It's the infirmary! One of the classic maps in that kind of manga! One careless move and boom—dodo happens!" Yuki declared solemnly.
"If I hadn't shown up in time just now, there's no way you'd have resisted that E-cup Alisa!"
"…Nonsense. Marikawa-sensei was there too…"
Yuki's eyes sparkled suddenly, her face lighting up with mischief.
"Ohh! So Marikawa-sensei was in on it too!"
"Of course! What kind of medical office romance doesn't involve a sexy school nurse?"
"And Marikawa-sensei looks at least F-cup from what I can tell—big bro, you really are a full-blown oppai-lover, huh!"
Kuzeha froze.
She's really my sister, alright. brain full of… imagination.
Bonk.
Kuzeha chopped her lightly on the head.
Yuki let out a strange yelp.
"Ah! Kuzeha-kun, so rough! Be gentle with me!"
Just then, a loud crash came from outside, followed by Alisa's frantic apologies:
"Sorry, Marikawa-sensei! I didn't mean to knock that over—!"
Yuki crossed her arms, smug satisfaction written all over her face. Kuzeha could only shake his head with a wry smile.
Compared to Yuki, both Sora and Alisa were still too green.
"…Only Akiko can give her a proper verbal fight," he thought, picturing a certain long-haired girl; Akiko Himenokoji, the queen of banter. Sharp-tongued like Yuki, but with zero follow-through. A trash-talker to the core.
Looking at Yuki, Kuzeha asked, "So… did you come to me for something?"
Yuki blinked, then suddenly remembered.
"Oh right! I heard from Sakura that you're planning to build a manor near the orphanage?"
Kuzeha nodded. From Yuki's look, he could already guess what was coming.
Sure enough—
"I have to get the room closest to you!" she declared, face turning serious.
"Nope."
"Don't tell me… Sora already claimed it!?"
"No. I made a rule this morning—whoever performs best during this period gets first pick."
Hearing this, Yuki straightened up immediately.
She patted her thigh and said with a grin,
"Big bro, you must be exhausted from classes today. Why not enjoy a special knee-pillow service from your little sister?"
Before Kuzeha could reply, she was already guiding his head down onto her lap.
Her fingers began gently massaging his temples.
"How's that? Comfortable, right?"
Seeing the tension melt from his face, she hummed proudly.
"Mhm. With this kind of care, Yuki's gonna ascend today," Kuzeha said, eyes closed, voice relaxed.
The lounge soon fell into peaceful silence.
After a few minutes, Yuki murmured quietly,
"Big bro… you've been carrying so much…"
A seven- or eight-year-old child, protecting an entire orphanage and raising countless lost kids.
Even though she had grown up in the comfort of the Suou family, Yuki couldn't imagine how he had survived those early years alone.
Kuzeha was about to speak, but suddenly, soft lips brushed against his.
A faint, sweet taste.
Kuzeha's eyes snapped open.
Yuki's long lashes trembled gently in front of him.
A few seconds later, she whispered,
"Spending this long in the infirmary and not doing something? That'd be such a waste."
"Shame it was over too quickly…"
"…Don't ambush me next time," Kuzeha muttered.
"Okay, big bro! Next time I'll go all in—"
Bonk.
"—Ow!"
Rubbing her head, Yuki grinned.
"Oh right, big bro—are you busy after school today?"
"I'm heading to kendo club for practice."
Yuki squinted slyly.
"Practicing with that Saeko-senpai again, huh…"
Seeing him nod, she pouted.
"She's older than me too…"
"I'm telling you right now," she said, puffing her cheeks, "if you're gonna build a harem, I get to be the head wife!"
Kuzeha raised an eyebrow. "What's with that obsession?"
Yuki held up her hand and gestured to her chest.
"Because I'm just a C cup! You know how satisfying it'd be to dominate all those oppai monsters from the top?"
She clenched her fist dramatically, like a revolutionary leader rising up.
"…Well, good luck then."
He ruffled her hair. At least she had dreams.
Outside the lounge, Alisa stared at the closed door, her blue eyes narrowed.
Her lips moved slightly.
"Twenty-three minutes and fifty-eight seconds…"
"…Fifty-nine…"
"Twenty-four minutes."
Ten minutes ago, Marikawa had already finished treating her sprained ankle.
But she could no longer feel the pain, her mind was completely occupied with what might be happening inside.
Twenty-four minutes…
That was more than enough time for that…
If the nurse hadn't told her to keep her leg elevated, she might've stormed in already.
Finally, when the school bell rang and thirty minutes passed, Yuki and Kuzeha stepped out.
Immediately, Alisa's eyes locked with Yuki's.
Yuki turned around, smoothed out Kuzeha's collar, and said sweetly,
"Kuzeha-kun, I'm very satisfied today."
One sentence.
But it sent Alisa's brain into overdrive.
Satisfied!?
What the hell did they do!?
She almost exploded from curiosity.
As Yuki walked away, Alisa looked at Kuzeha, opened her mouth to speak, then stopped.
She wanted to ask him directly. But… what if she didn't like the answer?
So instead, she muttered,
"I'm heading to the student council room."
Kuzeha picked her up and carried her there.
All the while, he could hear her muttering in Russian:
"If Yuki can do it, I can too…"
"No, I can do better…"
"Mmm, Kuzeha smells so good…"
"…I kinda wanna bite his cheek…"
By the time he gently set her down in the council room, he let out a long sigh.
If that walk had lasted any longer, he might've cracked.
"You rest now, Alisa. I'm heading out."
He waved and left.
Alisa, blushing, exhaled deeply.
She'd ranted so much in Russian earlier.
Things she'd never say aloud otherwise.
"…Good thing Kuzeha-kun can't understand it," she muttered.
Knowing a language no one else did… wasn't so bad.
"Alisa, what happened to your foot?"
A gentle voice came from the doorway.
A brunette who resembled Alisa entered quickly.
"You got hurt? Why didn't you tell your sister?"
Maria Mikhailovna Kujou—Alisa's older sister and fellow student council member.
"It's just a sprained ankle. I'll be fine in a few days," Alisa replied.
"Good… I'm glad you're okay."
Then, curiously, Maria asked,
"By the way… was that guy just now your boyfriend?"
"W-What!? Sis, stop jumping to conclusions!"
"Boyfriend? He's just my desk mate—Kuzeha."
"Just a classmate? But I saw him princess-carry you all the way here. Don't you like him?"
Alisa's face turned red. Her gaze darted everywhere.
Anything to avoid looking her sister in the eye.
But what she didn't notice was that Maria wasn't looking at her either.
She had a thoughtful expression as she bit her slender index finger.
"Alisa doesn't like him, huh…"
That face she'd seen earlier.
It overlapped with the image of a certain boy from her memories.
"Kuzeha…"
The day before the kendo tournament, Kuzeha intended to go easy on Saeko. Let her rest.
But instead, she showed up in a bikini.
A barely-there one.
Every move she made risked a wardrobe malfunction.
Kuzeha changed his plan immediately.
Intense practice session activated.
He feasted with his eyes. A full banquet.
"Thank you for training me all this time, Kuzeha-kun," Saeko said sincerely.
Her skills had improved dramatically.
Her strength had multiplied several times over.
But Kuzeha frowned.
"Just a thank you with words?"
To his surprise, Saeko gave a sultry smile.
"I was saving this for after the tournament, but… consider it an early reward."
"My mouth… isn't just for speaking."
Kuzeha quickly found out what she meant.
That evening, when he left kendo club, practice had gone on an hour longer than usual.
For the first time, Saeko's sorest parts weren't her arms or legs.
That afternoon, Kuzeha returned home.
Compared to Saeko, practicing with Suguha and Kanao was much less stimulating.
Since the tournament was tomorrow, he didn't have them train swordplay.
Their technique had plateaued for now—no point grinding further.
Instead, he had them reach "Total Concentration: Constant" with their breathing techniques.
With Kuzeha's modified version, it enhanced the body even more than the original.
No side effects either—basically a safe version of the demon slayer marks.
By his estimate, the two girls could now hold their own as Pillars in the Demon Slayer Corps.
"Big bro… after the tournament, can I keep training with you?" Suguha asked shyly.
"Of course," Kuzeha said, ruffling her hair.
"The tournament's just the beginning. There's a long road ahead."
Suguha beamed.
"I'll prepare a present for you next time, then!"
She ran off, blushing.
Kuzeha tilted his head, a bit puzzled.
But smiled and called back, "I'll look forward to it!"
That evening—
Sakura prepared dinner.
It was Friday, which meant the sisters studying outside would likely return.
So she made extra food and started earlier than usual.
Meanwhile, Kuzeha brought Ayumi to a remote plot of land.
Before Ayumi started school, he needed to help her fully master her "Collapse" ability.
