I Sealed Sukuna’s Finger#435+436: Yura-chan Wants Some Too, Senpai Wakes up!

Bokue wasn't entirely surprised that Yura would say something like that.

After all, Japan had no concept of "dating too young," so both boys and girls matured relatively early.

Under normal circumstances, if someone was reasonably popular, they'd have a romantic partner by middle school. Especially for girls—if you were still a virgin in high school, you'd likely get teased about it.

But being questioned by his little sister about this was admittedly a bit awkward.

And so, half a minute later, Bokue found himself half-forcibly dragged into Yura's bedroom and made to sit down on the tatami.

"Come clean. Did Brother use taking Senpai back to her hotel as an excuse to do something inappropriate with Busujima-senpai?"

"It wasn't anything inappropriate..."

Under his sister's scrutinizing gaze, Bokue's mouth twitched slightly.

While they had indeed done that, it couldn't exactly be called "inappropriate," could it?

"Then what exactly did you two do?"

The young Onmyōji girl narrowed her eyes, continuing to press.

"Brother's relationships with women are already complicated enough. Last time when you took me to Itogami Island, every single one of those ladies living at the top of the Stone Gate had an extraordinary relationship with you. And if that number keeps increasing..."

Bokue: "..."

Honestly, if it were anyone else nagging him about this, Bokue would've already sent a Heroic Fist their way to physically shut them up.

But sitting across from him right now was Yura. Yura was Yura, so he obviously couldn't do that.

After brief consideration, a little lightbulb dinged above Bokue's head.

"Oh, I remember now. We were just discussing Busujima-senpai's technique in her room."

"Technique?"

Yura paused slightly.

She knew her brother had never been interested in researching spells or techniques. His approach to using power was all about overwhelming force through sheer strength—simple and brutal.

He actually had the leisure to discuss techniques with Senpai?

"Actually, Busujima-senpai was the one who brought it up... about that incident at Kiyomizu-dera when she attacked me with her blade while in her Domain state."

Bokue said.

Oh, that...

Yura immediately recalled the scene in her mind.

Honestly, she'd been genuinely startled when she saw that happen. But since Bokue had left her floating in that light sphere barrier in the air at the time, unable to get out, she could only watch helplessly as events unfolded.

Fortunately, his strength had been sufficient to prevent any bad outcomes.

"So what exactly happened back then? Why did Busujima-senpai attack you, Brother?"

The moment anything related to her brother's safety came up, the young Onmyōji girl's attention immediately shifted.

"Well..."

Bokue got stuck here. While Saeko had brought up the topic at the time, she'd only mentioned it—there hadn't been any detailed explanation before things fast-forwarded to the next step.

However, judging by the feeling he'd gotten on Kiyomizu Stage, Busujima-senpai probably lost all rationality after Domain Expansion, leaving only instinct to guide her combat.

In that case...

"Probably a physical self-preservation mechanism."

Bokue came up with the most reasonable explanation he could think of at top speed.

"Yura, do you remember Busujima-senpai's attack patterns after activating her Domain? Her body simply can't withstand the force she outputs. Even just attacking tears her muscles and shatters her bones. That kind of pain isn't something an ordinary human could endure while conscious."

"Physical self-preservation... I see."

Hearing this, Yura nodded.

As the Keikain family's heir apparent, with her level of Onmyōdō mastery, she naturally understood what Bokue had just explained.

Simply put, the power Saeko unleashed after Domain Expansion completely exceeded the human body's safety threshold. Each attack was like forcing someone to smash their bare hands against a boulder until their hands broke.

Forget the subsequent pain—just the psychological barrier of breaking your own hands was incredibly difficult to overcome.

"Right, so then what?"

"...Then what?"

Bokue got stuck again.

He didn't know what specifically Yura's "then what" was referring to.

"Well, yeah?"

The young Onmyōji girl tilted her head as well.

"Didn't you and Busujima-senpai discuss technique-related topics? Didn't you reach any conclusion in the end?"

"Conclusion..."

Bokue hesitated once more.

"Hmm... the final conclusion was that Busujima-senpai needs to continue strengthening her physical body until it can handle the force output from Domain Expansion."

"You mean she needs to work hard training her body?"

"No... it's not quite that simple..."

Bokue scratched his forehead.

"To put it bluntly, I used my power to enhance Busujima-senpai's physical strength."

"Huh?"

Yura had expected some other explanation, but certainly not direct power transfer. She couldn't help but pause in surprise.

And when did her brother even have that ability?

"Brother, you mean you directly transferred your power to Busujima-senpai, thereby increasing her strength?"

"Exactly."

Bokue nodded affirmatively.

Everything else he'd made up on the spot, but this one point was an unchangeable fact.

After all, Kuroka—who he'd already "filled up" into a Transcendent—was proof of concept. Plus, everyone else including Rias and Akeno all experienced varying degrees of power increase after he "filled" them.

"Then... Brother, can you give me a little bit too?"

Yura thought for a moment and extended her hand.

The girl said it casually, but to Bokue's ears, it was an entirely different matter.

"Huh? What do you need that for, Yura? And haven't you always advocated relying on your own..."

"I'm just verifying it for you, Brother."

Yura kept her hand extended, insisting.

"Just a tiny bit. It's not like I'm going to rely solely on this method to get stronger from now on."

Hmmmm...

Bokue fell into thought.

Honestly, his spiritual power really wasn't suitable for distributing carelessly. Once someone was exposed to it...

"What's wrong? It's just a little bit."

While the young man was still hesitating, Yura across from him was already urging him again.

"Or did you actually use 'power transfer' as an excuse to get handsy with Busujima-senpai?"

"...Can you have just a little more faith in your brother, Yura?"

Bokue rubbed his forehead slightly.

Though it should be fine, right? After all, under normal circumstances Yura wouldn't have much intimate contact with him—at most just holding hands while going out together. And she probably wouldn't have lewd thoughts about him like Kuroka did.

It shouldn't trigger a "craving" state.

With that thought, under the young Onmyōji girl's watchful gaze, Bokue raised his hand and condensed a small sphere of golden magnetic field energy at his fingertip. With a light touch, it merged into Yura's small body.

"Mmm... so this is Brother's power? It feels warm, and also..."

Yura didn't continue. Under the bedroom's warm lighting, the flush on the young Onmyōji girl's cheeks deepened slightly, and her legs pressed more tightly together beneath her pajamas.

❁❁❁❁

At the same time, in Bokue's own bedroom—

The swordswoman lying under the covers slowly opened her eyes. Facing the pitch darkness that filled her vision, a warm, humid murmur escaped from between her lips and teeth.

"Bokue.."

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

Since he never managed to catch any dirt on him, Bokue only stayed in Yura's room for about ten minutes before leaving.

Late into the night now, the entire Keikain main estate had fallen quiet. On this late summer evening, aside from the cicadas still singing in the trees, only the rustling of wind through leaves could be heard.

The corridor of the family head's residence had no lights on, pitch black—though for Bokue this wasn't much of an issue.

He stopped at his own room's door and turned to look toward Yura's room. Only after seeing the light inside go out did he withdraw his gaze, sliding open his own door and walking in.

His room was also completely dark. Saeko Busujima seemed to have fallen asleep immediately after he'd tucked her into the futon. The room was utterly silent.

Bokue lightened his footsteps, treading on the moonlight filtering through the window onto the tatami as he approached the futon he'd laid out earlier. Without a second thought, he lifted the covers and lay down directly.

His head touched the pillow. Beside him came the swordswoman's gentle breathing.

So she really did fall asleep...

Bokue thought.

However, just as he was about to close his eyes and drift off, the swordswoman lying beside him silently opened her deep blue eyes.

At the same time, a pair of lotus-like arms—slender yet firm from years of kendo practice—coiled around his neck like two water snakes.

"Hmm? Senpai?"

Noticing Saeko's movement beside him, Bokue reopened his eyes and turned slightly to face her.

He wasn't entirely sure whether Saeko had actually woken up—it was also possible she just had a habit of hugging her pillow or bolster while sleeping at home.

But Saeko's next action proved her state of awareness.

She burrowed directly into the young man's embrace beside her, first burying her face against his chest and greedily taking a deep breath near his collarbone. Then her arms tightened slightly, pulling her entire body upward.

And then, Bokue's lips were once again covered by something soft.

Perhaps because she'd just woken from her dazed state and still lacked strength, this kiss was neither passionate nor particularly long-lasting, but it was certainly clinging.

As if trying to prove her feelings, Saeko offered up her soft lips again and again, kissing repeatedly. When she felt a bit tired, she'd release him to catch her breath for a moment before pressing forward to kiss him once more.

Only when she truly had no strength left did she finally relent, lying in the young man's arms and taking small breaths to steady herself.

After another two or three minutes, once Saeko's breathing had completely calmed, she rested her head on the young man's shoulder and let out what seemed like a murmur to herself.

"How surprising. I never expected you to be such a domineering person..."

"Is that so?"

Bokue's hand slid around the swordswoman's waist in his arms, neither confirming nor denying.

"Isn't it though?"

Feeling the slightly increased pressure from her abdomen, Saeko's face—hidden in the darkness—once again showed faint traces of crimson.

At this distance, every word she spoke sent her breath gently brushing against Bokue's neck up to his earlobe.

"Earlier in the hotel room, Kouhai wasn't trying to get me pregnant—you were trying to break me completely, weren't you?"

"'Break' is way too dramatic."

Even as Bokue spoke, the hand around the swordswoman's waist shifted slightly downward, his fingers applying a bit of pressure.

Mmph...!

Feeling the clear sensation of fingers beneath the hem of her yukata, Saeko's body trembled slightly as she instinctively bit down lightly on her lower lip.

But she continued speaking anyway.

"Really... isn't it? Then what if I still wanted to treat tonight as just an accident?"

"Then I'd just have to keep going until you passed out, Senpai."

Bokue answered without hesitation.

"...See?"

Saeko's voice paused briefly.

"There you go again. Doing whatever you want, disregarding everything, until the girl becomes completely your personal possession."

She said.

Saeko could distinctly feel that when Bokue said he'd go until she passed out, her abdominal muscles unconsciously contracted and transmitted obvious heat.

As if already preparing itself.

"But that's precisely why I'm even more..."

As Saeko spoke, she propped herself up slightly once more to kiss the young man's lips, exhaling breath saturated with affection from between her lips and teeth.

"After all, I... have long since become Kouhai's personal possession."

That's right—not just her body, but including her spirit. From the moment Bokue had clearly expressed that he didn't reject her true nature, she could no longer separate herself from him.

Like finding the only shelter in the vast world.

Saeko understood very clearly just how reprehensible her true nature was by conventional standards.

Whether it was the naturally combative genes inherited from the Busujima warrior bloodline, or the battle-lust trained through exchanges with her father and fellow students since childhood—she simply couldn't suppress the impulse to fight and slaughter her enemies.

But this was absolutely forbidden in modern society governed by law. If it ever came to light, even her father—who'd taught her swordsmanship since childhood—wouldn't accept it.

After all, her father could hardly imagine that his daughter, seemingly raised into a perfect yamato nadeshiko, would have such a side.

But Bokue was different.

For Saeko, if there was anyone in this world who could accept her worst side, it was without question her dear Kouhai—and him alone.

No, more accurately, he simply "didn't care."

And that very indifference was precisely what Saeko needed.

After all, if it were merely at the level of "acceptance," then that just meant "able to tolerate."

But only "not caring" meant truly being able to completely embrace her.

"So, Kouhai doesn't need any reservations..."

Inside the covers, the two pressed chest to chest. Saeko gently blew a breath toward the young man's ear.

"Please continue to use me as you please."

"..."

Moments later, as a soundproofing barrier spread throughout the room, the futon's covers were tossed aside. A pair of slender hands long accustomed to gripping sword hilts came to rest on the windowsill.

Facing the moonlight streaming through the window, Saeko's cherry lips parted slightly as she arched her neck high.

❁❁❁❁

At the same time, within the territory of the Keikain Fukuju branch family—

A figure clad in a black sailor uniform descended quietly on the moonlight atop the compound wall. Nine white fox tails swayed gently behind her. In her pitch-black eyes reflected the still-brightly-lit council hall within the branch family grounds, and the corners of her mouth couldn't help curving into a mocking arc.

"So desperate to survive..."
