While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 95: The True Monster’s Name (4)

Chapter 95: The True Monster’s Name (4)

“Nn…”

Takuya Yasuoka awoke.

Not due to Karin’s movements on his lap or her moans.

Just naturally.

“Suu… suu…”

Feeling her peaceful breathing by his ear and her warmth against his skin.

His exhausted body and mind, somewhat recovered, left him with a languid awakening.

…Then, he noticed a blanket draped over them, and as he vaguely pondered this—

“You’re awake.”

A voice prompted him to lift his gaze.

Over Karin’s shoulder, he saw a boy.

Even in the dimness, his eerie presence was unmistakable.

His stillness was almost unnatural, blending into the background—as if he’d been there all along, standing casually.

A male student from their school. A junior.

“You…”

Seeing him, Yasuoka felt a mix of tension and strange relief, an odd realization.

So that’s how it is.

The boy gave a faint chuckle, his voice bright with amusement.

“Man, I was shocked. To think it’d go this far. The power of a girl in love, huh? Terrifying…”

He called it “terrifying,” but his tone was almost gleeful, deeply intrigued.

He glanced at Yasuoka and Karin—naked, connected, draped in a blanket—nodding occasionally.

“…Did you do this?”

“Hm? Do what?”

“Don’t play dumb.”

Feeling Karin’s sleeping warmth and his own body regaining heat, Yasuoka grew slightly hot under the blanket. Shifting it to let air in, he stared at the junior.

“You’re the one who set this up, aren’t you…?”

“I didn’t do anything.”

“Liar…”

Yasuoka, weary and exasperated, dismissed the junior’s denial.

“Yuu Onodera or Yakko Tsukimi… what, were they both too precious to you…?”

“…”

The junior listened with interest, his silence urging Yasuoka to continue.

“Using some guys to rough up Onodera and Tsukimi… make them damaged goods… so I could claim them. Too obvious a plan, huh…?”

“…”

The junior remained expressionless, silent, just listening.

“Didn’t think a monster like you was hiding among the regular students…”

“Monster, huh?”

The junior shook his head weakly, as if saying “come on,” with a slightly mocking air.

“Hey, where’d you hear about my plan…?”

“Who knows who I got it from?”

“Damn joker…”

Yasuoka clicked his tongue.

Yet, oddly, he wasn’t upset talking to this junior, which surprised him.

“The more people you involve, the harder it is to trace the leak. Probably just heard it from some guy, right? Let’s go with that.”

“…”

This guy’s such a joker, Yasuoka thought, echoing his earlier sentiment.

“You’re the one who put weird ideas in Karin’s head, aren’t you?”

“Weird ideas? I didn’t say anything weird.”

“You’re not gonna say you only told her what she needed to hear, are you?”

“Well, the bare minimum.”

“So you did egg her on…”

Expecting a full denial but getting a half-admission, Yasuoka fell silent.

Karin, now asleep against him, had been driven to this deranged act—she was used.

He felt she’d been manipulated to trap them both, a chill running down his neck.

“No idea what you’re misunderstanding, but I meant well.”

“Meant well, my ass.”

Whether to ease Yasuoka’s suspicion or not, the junior’s playful remark made no sense to him.

“Remember?”

“…?”

But then, the junior turned his clear eyes on Yasuoka with a meaningful look.

“When I asked, ‘Is a girl like Yuu your type?’ you nodded and said, ‘Something like that.’”

“…!!”

Yasuoka’s eyes widened, shock plain on his face.

He didn’t understand.

…No, he did recall his own words, but the junior’s intent eluded him.

“Well, tying your beloved to a place outside your territory… Yuu would call that ‘sloppy.’ But I’m the one who suggested this place. Karin’s house would’ve been risky—if you yelled, neighbors might hear, causing a scene. Gagging you to silence your talk felt wrong, too.”

“You…?”

“Someone like Yuu—with a similar mindset, brimming with possessive desire, given the same tools and justification—would end up like this, I guess.”

“What the hell are you talking about…?”

Yasuoka’s mind filled with question marks.

He couldn’t grasp the junior’s words.

…No.

With thought, he could understand, but it was too absurd, like something from another world.

It didn’t feel like a grounded, realistic conclusion.

And the junior’s detached attitude—yet oddly sincere—felt bizarre, deepening Yasuoka’s confusion.

But—

“You… you didn’t…”

One thing was clear.

“You planned all this from the start, didn’t you…!?”

“…”

The junior stayed expressionless.

Silent for a moment, neither confirming nor denying.

“Not exactly planned. But tailing you was overkill. Getting guys to attack girls, fostering that kind of mindset—it didn’t take long to notice your plan. It’s done now, so whatever.”

“What—!”

Manipulating elements on a grand scale, using people’s emotions to create a desired outcome—Yasuoka had done the same.

Using lackeys to mess with Yuu Onodera and Yakko Tsukimi, shaking up the junior himself.

Normally, they’d have fallen. They’d have wavered.

An ordinary high school boy, lucky or kind enough to win a girl’s heart, should’ve been easy to manipulate.

But this time, Yasuoka’s moves were all blocked.

Maybe, from the start, this junior saw through everything—

“My lackeys…! What happened to them…!?”

“Oh, that Mana girl and… some senior guys, right? We used people, too, and got leverage on a few. Controlling someone with influence means you can make others below them—or unrelated—back off. Takes less effort than you’d think.”

“…!!”

…What the hell?

A quiet, nerdy junior, moving so precisely, so swiftly.

And so covertly.

Like a spider ensnaring prey in its web—

“When did you…?”

This wasn’t just skill.

To Yasuoka, the junior seemed even more unfathomable.

He didn’t feel like he was talking to a first-year high schooler.

The boys he knew were reckless, immature, passionate about clubs, studies, or hobbies—

And easy to handle.

Or so he thought.

“You…! Ren Hoshimiya… what the hell are you…!?”

That junior—Ren Hoshimiya.

He didn’t fit any category of human Yasuoka knew.

“You know me well. Got my name right. You’ve got the gist of it. Just a plain, ordinary, unremarkable Mob C—something like that.”

“You bastard…! Still screwing around at a time like this…!?”

“I’m not screwing around. I’ve been living desperately, you know…”

“…!”

Ren’s words grated harshly on Yasuoka’s nerves.

“‘Living desperately’!? You set people up, then stand there acting like a bystander!”

“…”

Ren’s eyes widened slightly, but he nodded as if understanding and spoke.

“You can’t tell someone’s history at a glance. Their character, how they’ve lived, what they carry inside, how they see things… you need to observe closely. Even then, it’s hard to grasp accurately.”

Ren narrowed his eyes, speaking with a gentle expression.

“You should think more about yourself, Yasuoka-senpai, and the people who love you.”

“…Tch!”

Yasuoka clicked his tongue irritably.

…And then.

“Karin-senpai even took ovulation-inducing drugs… she’s serious.”

“What?!?!”

Ren’s next words left Yasuoka pale, mouth agape.

“She prepared them herself. I tried to stop her, just so you know. I tried, but…”

“What?!?!?!”

Yasuoka’s face drained, his mind blank, staring incredulously at the sleeping Karin, her chin on his shoulder.

“Suu… suu… suu…”

Her slightly disheveled black hair clung to her sweaty back, rising and falling rhythmically.

She breathed peacefully.

“Karin… you…”

“Suu… suu… suu…”

Her face was hidden, but her breathing was utterly serene.
