While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 97: The True Monster’s Name (6)

Chapter 97: The True Monster’s Name (6)

By the way, it’s Golden Week.

The day after Takuya Yasuoka’s confinement incident, I was handling the aftermath for both him and Karin Hanazawa. It’s already cost me tens of thousands of yen, but… oh well. Just one more phone call to wrap things up.

Even over the phone, the voice on the other end dripped with drowsiness, trembling, followed by the sound of a nervous swallow.

“Um… is this really… about the Student Council President… Yasuoka-kun…?”

“Yes, thank you for your help. Thanks to you, he’ll have a chance to reflect on his behavior.”

“So… it really… worked…?”

“Yes, everything went perfectly. Yasuoka-senpai won’t have the energy to stir up trouble anymore. So, please, get some good sleep from now on. Take care.”

“W-Wait, wha—”

Beep.

The senior’s voice was flustered, timid, and shaky.

At first, I thought she just sounded sleepy, but… it seems a certain incident has left her, still young, suffering from insomnia. What a pity.

The pain of sleeplessness is indescribable. I hope she can finally enjoy some rest.

Alright, job done!

Golden Week has kept me busy, and with only two days left, including today, it’s been quite a ride.

Sure, I sacrificed a couple of days, but the payoff seems worth it.

Case in point—

“You ended up dismantling the harem Student Council, huh? ♥”

“Yeah, pretty much.”

Yuu, always clinging to my arm even indoors, said that.

Well, that’s not entirely accurate.

“I never planned to get involved with the Student Council, whatever form it took…”

“Nfufu! ♥ Ren-chan’s precious girlfriend was targeted, so it couldn’t be helped, right? ♥”

“…”

True, once Yasuoka set his sights on Yuu, we had to take action. But knowing Yuu, she’d have handled her own defense if targeted, and I’d only need to back her up.

…This time, I had to orchestrate things and involve others because another vulnerable girl was in his crosshairs.

“That guy’s downfall was not understanding others’ hearts. He toyed with the pure feelings of the girl closest to him—Vice President Karin Hanazawa. It’s just desserts, but he probably still doesn’t get it. If he thinks it’s all because ‘Ren Hoshimiya got him,’ he’s truly beyond saving.”

“…”

Yuu spoke with conviction, staring into space, nodding slightly with an expressionless face. What’s going through her mind?

“I could’ve ended up like him if I’d taken one wrong step.”

“Ren-chan…”

Yuu’s dark, abyssal eyes welled up, tightening her grip on my arm.

The sensation of my arm nestled between her soft curves felt blissful.

Her body, even through her blouse, was soft and faintly warm.

“No way… absolutely… Ren-chan, you’d never become like that…”

“…”

Yuu says that, but… who knows? That’s all I can say.

From what I dug up, Yasuoka’s home life was a mess.

Despite that, he excelled academically, served as Student Council President, and earned a certain level of respect for his abilities, regardless of his reputation among peers.

His womanizing was his glaring, warped flaw.

…Talking to him directly, I didn’t get the sense he was rotten to the core (though he’s somewhat tainted).

He wasn’t corrupted by being overly indulged, festering in stagnation.

No, he was someone hardened by struggling in the mud—a mentality unique to that.

Use whatever’s available. Use everything and everyone to keep searching for something.

Not just hungry for women, but for something else—something deeper.

I can’t fully explain why I got that impression or how I saw through him…

Maybe it’s empathy.

Maybe, at his core, he’s a lot like me.

“Ren-chan…”

Yuu’s teary eyes locked onto mine from close range.

A maddeningly intense light in her gaze fixed on me.

“R-e-n-c-h-a-n h-a-s m-e, right…? So… okay…?”

“Yuu…”

She shook her head, then nodded, her glossy black hair swaying, as if to affirm her presence.

Then—

“Hey, you two?”

““Hm?””

We turned toward the voice.

The speaker, the room’s owner—no, the house’s owner—was—

“Flirting in someone else’s house is a bit much, don’t you think?”

With an exasperated look, Yakko Tsukimi, her blonde twin-tails a signature, narrowed her sharp eyes at us.

“Fair point.”

“…Ugh, don’t interrupt us at a good moment, Tsuki-chan!”

“No, I mean, this is my house…”

Right, we’re at Yakko-chan’s place.

I felt bad intruding during Golden Week, but she lives alone, so she said it was fine.

Yakko-chan’s not the type to go out and have fun, so this setup feels natural enough.

“By the way, you insisted on inviting us, so here we are… what’s up?”

“Um, well…”

Yakko, fidgeting shyly, explained why she invited us.

“I thought… maybe we could play some games together, like old times…”

““Games?””

“Yup.”

With that, Yakko, still in her tracksuit, lightly stepped to her room and pulled out a few board games.

“Ta-da!”

“This is…”

“Lonely Tsuki-chan has a ton of games for group play…”

“That’s a bit harsh, Yuu.”

“No big deal! I just… kinda… bought them on Am*zon by mistake!”

“Wow…”

“Stop it, Yuu.”

Despite Yuu’s sharp jab and Yakko’s defensive excuse, the games Yakko brought were TRPGs—tabletop role-playing games. In Japan, they’re often called “table-talk RPGs,” but the term technically comes from “tabletop role-playing game.”

No computers, just conversation-driven gameplay. Following a rulebook, a game master guides the story, players take on roles, and the narrative unfolds. Some use dice, like board games, others use cards, spanning a wide variety of styles. A dream for game, manga, or story lovers.

“…So why suddenly want to play this with me and Ren-chan?”

“No biggie, right? Do you have to question your friends like that?”

Yuu pursed her lips, questioning, while Yakko did the same, annoyed at the probing. She seemed to want Yuu to just get it.

“…You plotting something shady?”

“N-No way!”

Yakko averted her eyes, making a poor attempt at whistling. Are there even shady motives in multiplayer games? This isn’t a mixer.

“What, planning to marry Ren-chan in the game or something sneaky?”

“Okay, let’s do this!”

Yuu’s paranoia veered into absurdity, so I cut in quickly.

“Whatever, let’s play, Yuu.”

“Nice, Ren-kun gets it~!”

“Ugh… Ren-chan, you’re so innocent sometimes…”

Yuu gave in, seeing my enthusiasm.

…I’ve always wanted to try a TRPG!

*

So…

“If the die roll is odd, the swordsman dodges the dragon’s breath. If the next roll is four or higher, the swordsman lands a critical hit to slay the dragon.”

“Come on, Yuu-chan!”

“Come on? It’s just luck. There’s only a one-in-four chance of pulling it off…”

The dice clattered lightly, stopping.

Yuu’s two rolls: “5” and “6.”

Success! Swordsman Alexander-Yuu dodged the ferocious attack of Evil Dragon Dragunov J. Paranoia and felled it with a single critical strike!

“Hahaha! Yuu-chan’s crazy strong!”

Yakko clutched her stomach, laughing by the living room table.

“…”

Yuu, sitting primly at the table, looked displeased, her face sour.

“And so, the two adventurers, with brilliant teamwork, defeated the dragon. They claimed its treasure, securing a foundation for a stable life.”

“Happily ever after,” I, the game master, concluded, as two sighs followed.

“Hahaha, that was fun~!”

“I wanted to adventure with Ren-chan…”

“We agreed not to say that!”

Despite the game’s happy ending, both looked unsatisfied. Yakko seemed somewhat content, though.

Well, with these two, this reaction makes sense.

…I wanted to adventure too, you know!

Why’d my first TRPG have to be as game master? I wanted to be a player, not a narrator! Damn you, rock-paper-scissors gods!

“Also, does this mean the adventure continues? This story…”

The storyline intrigued me more. It felt like it could go on, with a realistic, bittersweet edge—like the fleeting nature of windfall gains.

It practically called adventuring an “unstable job.”

Harsh world…

But sword-and-magic adventures are so cool.

“I’d have switched with Ren-chan… ugh! But then Ren-chan would’ve adventured with Tsuki-chan…! Unacceptable!”

““…””

Yuu clutched her head, wrestling with her possessiveness, but never mind that.

“So, what’s next? Ren-kun as player, and who’s his partner—”

“No, wait.”

Yakko threw out that hellish dilemma.

She could’ve just let Yuu have it… but slipping herself in as an option is so her.

“Is there a three-player game? All equal, all three of us.”

““Hmm…””

I’m not criticizing TRPG systems, but most require a game master. Typically, there’s a storyteller role separate from the characters.

“Oh!”

Yakko’s sudden idea drew our eyes.

“You two still play that app?”

““App…?””

Yakko beamed, clearly struck by a great idea, while Yuu and I tilted our heads.

An app we all share… oh, that one!

“…I think my data’s still in the cloud…”

“Same.”

“Then it’s settled!”

Yuu and I answered, and Yakko grinned happily.

*

“Ugh, I hate this boss!”

“Me too, I struggled with it the first time.”

“Really? I’m still bad at it.”

“Once you get the knack, it’s easy.”

“Oh? If you’re so confident, let’s see Yuu-chan take it down~☆”

We were playing a famous puzzle game.

Intuitive controls and satisfying gameplay—a pioneer in monster-collecting, puzzle-solving, battle-and-gacha apps… or its legitimate successor, rather.

It’s been years since it launched, but… it’s still running (!).

Our multiplayer mode involved setting up a dedicated room for battles.

It’s a mode where we burn stamina to face bosses, not a practice mode but one with rewards, adding thrilling tension.

“What!? Why’d you leave such a messy board for me!?”

Yuu, up after Yakko, shrieked at the puzzle board she inherited.

“Sorry, sorry~! It’s tough to control☆”

“You did that on purpose!”

“Hurry, or you’ll leave a mess for Ren-kun’s turn~!”

“Ugh… you’ll pay…!”

“You two are getting way too into this.”

Since it’s a shared puzzle board, the previous player’s actions heavily affect the next.

What Yakko just did (probably on purpose, as Yuu said) was a classic “troll play.”

“I won’t lose…!”

Yuu activated one monster’s skill from her team, then smoothly manipulated the puzzle with deft fingers—

“—Oh!?”

She took down the tricky boss on her turn.

But—

“Ugh!! Sorry, Ren-chan!! I left one bad tile…!!”

“Whoops~♪”

“Quiet, you culprit! Because of you, Ren-chan’s—!”

“No problem.”

The boss on my turn was one that spawns bad tiles for several turns. No big deal.

“I’ll clear the bad tile too.”

I used a skill to wipe the bad tile and prevent more from spawning.

We’re using old characters against nostalgic bosses, and I’m moved that we can still fight like we did back then—and that the game still supports it.

“Nice one, Ren-chan! ♥”

“Hahaha! You’re both so strong!”

Yakko’s having a blast, as always. That’s what matters.

“Next is the final boss. You good, Yakko-chan?”

“Huh?”

I’d just cleared a mid-boss, passing the turn to Yakko as the screen shifted.

Up came a grotesque, whale-dragon hybrid monster.

This creepy final boss hits hard from the start. Survive its initial attack and kill it in one turn, or its onslaught will wipe you out.

“I forgot… yeah, this guy…”

Pale-faced, Yakko hesitantly reached for her phone—

“Oh!?”

““What?””

No wonder we were shocked.

Because—

“I used the wrong skill…”

““…””

The screen was a sea of red—a completely unplayable board.

This is hopeless…

“What do I do…!?”

Yakko looked at us, teary-eyed, seeking help.

“Tsuki-chan… we’ll never forget your sacrifice.”

“Farewell, Yakko-chan. Thank you, rest in peace…”

“Waaah!!!”

Yakko spammed skills recklessly, fumbled the puzzle, dealt chip damage to the high-defense boss, and was swiftly taken out by its attack.

“Waaah!!!”

Crying out again, Yakko dove into a nearby sofa, burying her face in a cushion, mumbling complaints—likely about Yuu, who ignored her completely.

“All done! ♥ Cleared the boss for Ren-chan! ♥”

“Nice, Yuu.”

No spotlight for me—Yuu easily beat the boss, ending the game. We got some nice rewards, and the multiplayer room disbanded.

Our old characters can’t keep up with the current meta.

I get why gacha games inflate power levels for revenue, but recalling the game’s current reviews about broken balance, I closed the app with a sense of harsh reality.

“…Man.”

It wasn’t just harshness. There was nostalgia, too.

“Felt pretty nostalgic.”

“Yeah! ♥”

“…Fugo.”

Yakko, face still in the cushion, deliberately said “fugo” as a weird reply.

“Back in middle school, we’d sometimes hang out and game like this, right? Gurgle.”

Oops, my stomach growled mid-sentence.

““…””

“…Don’t look at me like that.”

Yuu and Yakko stared, wide-eyed.

“It’s lunchtime, huh? ♥”

Yuu used my stomach as a clock.

“Body’s honest, huh? ☆”

“Shut up.”

I couldn’t deny Yakko’s tease, though.

Ugh… my body’s so honest lately with this regular lifestyle… my stomach aches for food at mealtime…

“Oh, I forgot to tell Mom I don’t need lunch—oh, a message.”

“…”

Yuu’s lunch-mode muttering made me glance at the living room clock. My stomach was right—it’s past noon. We were so into gaming, time flew.

“…Huh?”

Yakko, lifting her face from the cushion, hair messy, looked at us with a question mark.

“Yuu-chan, don’t you usually cook for your family?”

“Yup.”

“Your mom’s cooking now?”

“Yup.”

“…”

“…”

Why did that exchange spark tension?

“…?”

Forgive my confused head-tilt.

The two shared a strange pause, locking eyes with mutual restraint.

“…W-h-y? Why all of a sudden, again?”

Yakko, sitting upright on the sofa, asked nervously after a long pause.

“Why, you ask…?”

Yuu faltered, but her eyes and expression showed no hesitation.

Yakko’s brown irises glinted with conviction as she pressed.

“…What, you’ve been that busy lately?”

“Something like that.”

“…”

“…”

Another weird pause.

They stared intensely—wait, a yuri twist? No way.

No chance of such a flowery development now.

“Why? Why’d you suddenly stop cooking?”

Yakko’s voice trembled, tense, her expression fearful.

“‘Why’? That’s obvious, Tsuki-chan.”

Yuu brushed her glossy black hair, meeting Yakko’s gaze head-on.

“I’ve been cooking for Ren-chan all this time.”

“…”

Yakko froze, staring at Yuu in disbelief.

Yuu stared back.

“…You two?”

Something’s off.

The flow.

The vibe.

It’s wrong.

Why’d it turn out like this?

I was trying to spark a nostalgic chat—middle school memories, laughing over silly times.

I wanted that warm, reminiscent vibe, leading to lunch or grocery shopping—

Why don’t these two ever follow my plans?

“…S-t-a-l-k-e-r’s gotten cocky.”

Yakko muttered, her sharp words piercing.

“Huh? What’d you say?”

Yuu, instantly livid, glared without blinking.

“Hey, you two—”

This isn’t it. This fight isn’t what I wanted.

“Tsuki-chan’s the stalker, chasing someone else’s boyfriend—”

“Like you’re any different. Just happened to meet him first—”

“—Huh?”

“—Huh?”

No, I’m the one saying “huh” here.

Stop, not now.

“I know. The other day, you checked Ren-kun’s bag, taking notes on his stuff—”

“Oh, that? Ren-chan noticed, no big deal.”

“Really? Shall we confirm? Ren-ku~n—”

“You’re so desperate to dig up dirt on Ren-chan’s girlfriend? Trying to break us up?”

“Yeah, so what? I still think it’s weird Ren-kun’s with a nutcase like you.”

“Huh? Who’s the nutcase?”

“You, obviously! Why you’d think otherwise is beyond me.”

“If we’re talking nutcases, look at yourself! Trying to kill Ren-chan—you’d be in jail if he weren’t so kind to a ‘mere friend.’ Be grateful.”

“Friend… huh.”

“Oh? Did that sting? Truth hurt?”

“Think being his girlfriend makes you untouchable? Laughable. High school girlfriends are just future exes.”

“That’s you, Tsuki-chan. Acting like you and Ren-chan have some past? That’s so cringe. It’s what nobodies say to seem relevant.”

“If you think there’s nothing, fine. I-t d-o-e-s-n-’t c-o-n-c-e-r-n y-o-u, right?”

“It does concern me. I’m Ren-chan’s girlfriend. Wanting to know everything about my boyfriend is natural.”

“Can’t you get that’s not how it works? You’re so—”

“What?”

“What’s that?”

Ah…! Aaaah…!

I hear my daily life crumbling!!

“R-Ren-chan…!?”

“R-Ren-kun…!?”

“…”

They looked up, startled, as I stood abruptly, but I didn’t care.

“You two, we’re going grocery shopping!!”

““Huh?””

“Follow me! Don’t lag!!”

I checked my phone and wallet in my pocket, then dashed to Yakko’s front door—

““Ren-kun-chan?!?!””

…I put on my shoes properly and bolted outside.
