I Sealed Sukuna’s Finger#364+365: The Best Special Attack Against Bokue, One by One, Threaded Together

It was hard to imagine such perfectly aligned kindred spirits could exist in this world.

Two girls with a full three-year age gap—supposedly an entire generation apart—had hit it off immediately. From the moment they'd met, their discussion about "the charm of small chests" hadn't stopped once.

So they chatted from nine in the morning straight through to nearly eleven, approaching noon.

Even when the living room clock showed past ten-thirty, the two girls remained absorbed in sharing fashion tips.

"Oh~ I see! I never knew there was this kind of styling method... But that's true—this way even small sizes can show off obvious body curves. Learning so much~"

As the faint sounds of the Sword Shaman opening the refrigerator to select ingredients drifted from the kitchen, inside the apartment bedroom, Nagisa and Yuuma—one younger, one older—still huddled excitedly by the wardrobe, discussing away.

Various cute girl's clothes covered the entire bed.

Yuuma currently had one hand on the wardrobe door, the other holding up a skirt hem as she held it against herself.

The skirt was naturally Nagisa's—a middle schooler's size that obviously wouldn't fit someone like Asagi Aiba.

Fortunately, Yuuma had a naturally slender build, and certain parts hadn't developed as dramatically as the "cow" she'd mentioned. So Nagisa's clothes could actually fit her reasonably well, just a bit short in length—which had its own appeal.

Kind of like a delinquent high school big sister deliberately shortening her clothes into a crop top.

"Wow~ I didn't expect Nagisa-chan to have so many clothes despite being so young!"

In front of the bedroom's full-length mirror, Yuuma raised both arms and spun in place, admiring the effect of her changed style. Then she unbuttoned the skirt and handed it back to the equally beaming Nagisa beside her, winking teasingly.

"So with all these pretty clothes and such good fashion sense, is Nagisa-chan specially learning this to chase after some boy?"

"Hmm, not really..."

Nagisa tapped her lip thoughtfully.

"It's just my personal hobby. After all, dressing up prettily makes me happy too."

She finished with narrowed eyes and a slight smile.

Actually, Nagisa had left the second half unsaid—if she wanted to chase after Big Brother, not wearing anything at all would be more effective.

Just then, someone peeked into the bedroom from outside, accompanied by a slightly helpless voice.

"You two, about today's lunch..."

"Ah, sorry sorry! Yukina, I'll come help right away!"

Hearing her friend's voice from behind, Nagisa—standing by the bed—immediately turned with an apologetic smile.

They had indeed gone too far—spending the entire morning chatting about clothes while completely ignoring Bokue and Yukina.

"No, that's not what I meant..."

Yukina sighed softly in resignation.

"I just wanted to ask if Miss Tokoyogi has any dietary restrictions, or anything she particularly likes."

"Eh? Me?"

Not expecting to be asked for her opinion, Yuuma froze slightly, then waved her hands in surprise and apology.

"It's fine, it's fine! You don't need to prepare anything for me—I'm planning to eat out for lunch."

"Eat out? There's no need for that. We just bought lots of ingredients a couple days ago..."

Nagisa thought she was just being polite and tried to persuade her.

After all, finding such a like-minded small-chest ally was rare—and she was Big Brother's childhood friend too. They should definitely bond properly.

"No no no, I really don't need anything."

Yuuma waved even faster.

"I wasn't even planning to come here today originally. I only thought to visit after running into Bokue at the Keystone Gate this morning. Actually, if I hadn't met Bokue, I had other plans today—my whole sightseeing itinerary was already set. Right now I'm planning to have lunch back at the Keystone Gate—the restaurant's already booked and non-refundable, so I have to go."

"I see, well then..."

Though disappointed, since she'd already booked a restaurant, Nagisa couldn't insist she stay.

"Yeah, next time then, if there's a chance."

Checking the time and confirming it was getting late, Yuuma decisively bid farewell.

"I'll head out first today. Won't disturb you all anymore~"

"Okay, see you next time then."

Nagisa said while casually closing the wardrobe door beside her, then escorted Yuuma out of the bedroom.

But she didn't notice that as the wardrobe door closed and darkness returned inside, a blue mark was faintly glowing where Yuuma had touched the inner door panel, emanating subtle spatial magic fluctuations that were hard to detect.

❁❁❁❁❁❁❁❁

After saying goodbye to Bokue, Nagisa, and Yukina—the scene shifted to Yuuma already downstairs.

Using the excuse that "I can make it by bus anyway, and I'm here for sightseeing so I want to properly explore the city," she politely declined the young man's offer to transport her back to the Keystone Gate.

Instead, she went to the bus stop by the roadside in front of the apartment building.

As noon approached, the sunlight beating down grew increasingly fierce.

Thirty-seven degrees outdoor temperature plus the blazing sun—enough to make someone pass out from heatstroke in just tens of minutes.

Fortunately, by coincidence, just as Yuuma reached the bus stop, a bus heading downtown was slowly approaching from the nearby intersection.

She normally paid the fare and boarded, then walked through the packed front half of the bus to the relatively empty rear section.

Yuuma had just picked a double empty seat when a certain pair of witch sisters' voices came from behind.

"So this is your plan? What about progress? When exactly are you planning to officially start?"

"Hmm... don't rush. The timing will come soon."

The short-haired girl knew who was sitting behind her without turning around, smiling lightly.

"My 'Le Bleu's' ability exchanges both parties' five senses through spatial replacement, but it's not powerful enough to work on just anyone. We're talking about the world's strongest vampire—even among Progenitors, she's top-tier. I need to wait for the moment her mental defenses weaken to activate 'Le Bleu' successfully."

"..."

But it was undeniable—the Fourth Progenitor was called the world's strongest vampire, not something one or two witches could easily control.

After a while, the more impatient younger sister in the red hood, Octavia Meyer, couldn't help speaking again.

Only this time, her voice carried something subtle.

"So is your plan really reliable? What if they don't... you know... then wouldn't it..."

"Don't worry, they will."

Yuuma shook her head with a smile.

"Know why?"

"...Why?"

"Because I could tell—that Progenitor lady was already impatient when we first met this morning."

Just like me.

<><><><><><><><>

The perspective shifted back to the apartment.

Yuuma had just left. With her usual partner-in-crime gone—someone she could at least gossip with about “small chest appreciation”—Nagisa’s focus snapped immediately back onto Bokue.

“Hey, big brother.”

“Hm?”

“When Yuuma-senpai came by earlier, she said she ran into you this morning near the Keystone Gate. So what were you doing there?”

Her tone remained as calm as always, but the faint flicker in her eyes betrayed a touch of pouting jealousy.

After all, the Keystone Gate wasn’t just the central pillar of Itogami Island’s management system—it doubled as the island’s largest shopping plaza. Normally, that was a place you’d go with friends.

But according to Yuuma, she’d spotted Bokue there alone. Meaning—what? He’d rather go wandering around the biggest plaza on the island by himself than take Nagisa with him?

“Why? Oh, that’s simple. I was dropping Asagi off at work.”

Bokue shrugged as if it were obvious.

“You know this already, Nagisa. Asagi works at the island management bureau. Sure, most of the time she works remotely, but sometimes she has to show up in person. Today was one of those mornings, so I just walked her there.”

“Eh? Oh... I see.”

Nagisa wasn’t the type to cling or push for no reason. She was smart, quick to piece things together.

Her mind immediately filled in the blanks: Bokue must’ve just dropped Asagi off, and right as she left, Yuuma happened to walk by—then came straight here afterwards.

That made sense.

“Mm. So that’s how it was.” She nodded, lips curling into a faintly relieved smile. “Alright then, guess I misunderstood. No problem, no problem.”

“Misunderstood? Misunderstood what?”

Bokue blinked, still not following.

“Hehe... nothing at all~” Nagisa replied with a mysterious smile.

“More importantly—since Asagi-senpai’s at work, that means you’re completely free until five o’clock, right?”

“...”

The way she phrased it sent a strange déjà vu through his head. Where had he heard this before? Oh right—Yuuma had said almost the exact same thing earlier.

“Am I wrong?”

Nagisa pressed the point sweetly, stepping forward. Then she lifted the hem of her skirt slightly, turning her back toward him.

“In that case, no time like the present. Let’s start—”

“Hold it, Nagisa. We haven’t even finished lunch yet.”

The voice came from the open kitchen, where Yukina had already laid out the ingredients: slices neatly arranged, vegetables shredded, all washed and drained in colanders.

The Sword Shaman raised her eyes just enough to meet theirs, expression calm but sharp.

“At least wait until after we eat.”

“O-of course, of course~” Nagisa chirped back instantly. But she wasn’t ready to drop it just yet. Her eyes flicked mischievously toward Bokue.

“Still, meals aren’t the only important thing, right? And come to think of it... Yukina-chan, you complained before that the stove here was too tall, remember? You always said it was hard to use without standing on something. Well—since big brother’s here today, you won’t need a stool anymore, will you?”

“What does him being here have to do with—” Yukina started, but her words froze in her throat as Bokue suddenly walked over.

And then—he wrapped his arms around her from behind and lifted her clean off the ground, adjusting her height so she matched the stove perfectly before setting her gently in place.

“Eh?? Wh-what are you doing—wait, don’t tell me you actually plan to—?? If you do that, then I... I won’t be able to—mmph!”

“Exactly like that~”

Nagisa clapped her hands together in satisfaction as Yukina, suspended thirty centimeters higher than usual, stood flushed and helpless before the stove.

“Good luck, Yukina-chan. Better hold on tight. If you slip and spill into the pot, well... let’s just say today’s lunch will come with extra toppings.”

“...”

Yukina wanted to protest, but her logic, composure, even her willpower had already abandoned her.

Of course, nothing actually spilled into the pot. Bokue wasn’t about to let that happen.

By the time lunch was served, the dishes had been joined by a... let’s say, “special supplement.” Yukina’s belly was visibly rounded when it was over, and the apartment was filled with the mingled scent of food and a faint, flowery sweetness—something almost like blossom-scented cauliflower drifting faintly through the air.

Afterwards, as Nagisa cleared the empty dishes and stacked them by the sink, she carried the leftovers to the fridge. Turning back, she caught sight of Yukina slumped weakly in a chair, cheeks flushed, lips trembling as if to speak but failing to muster even a whisper.

A smear of oil still clung faintly to her lips. And beneath her chair... well. The less said, the better.

Seeing her friend in such a state, Nagisa only pressed her palms together and smiled.

“Big brother... looks like Yukina-chan really enjoyed that meal~”

“Good.” Bokue’s voice came from the kitchen, water running into the sink.

“Ah—wait, big brother. Leave the dishes to me.”

Nagisa quickly set down the last plates and stepped lightly into the kitchen, nudging him aside so she could take his place at the sink. She stood deliberately with her back to him, hips tilted, skirt swaying slightly.

“Yukina-chan handled the cooking, so of course I should do the cleaning. That means you—” She glanced back over her shoulder, cheeks warm.

“—you’ve got your own job, big brother. Just like you helped Yukina earlier.”

And with that, she lifted the hem of her skirt in invitation.

“Help me with a little... stool too, okay?”

“...”

And just like Yukina before her, Nagisa’s feet left the ground.

❁❁❁❁❁❁❁❁

Meanwhile—

Inside the darkened closet of the bedroom, a faint blue crest carved into the wood suddenly glowed. A ripple of light shimmered, and Yuuma appeared silently in the shadows.

Pressing her ear lightly to the door crack, her face tinged pink, she exhaled softly.

Looks like... they’ve already started.
