Somehow I Ended up Dating the Perfect Female Classmate, but My Sister Found Out and They're Turning Into Yanderes - Chapter 103-104

Chapter 103: Kirino Has Gotten a Lot Stronger

School ends at lunch, and I head home together with Kirino.

Our class did end up deciding to practice after school, but they took pity on us and said we didn’t have to do it today.

“Most of the first- and second-years are practicing on the field.”

Just like Kirino said, almost every first- and second-year class is out there practicing different events.
Our school’s field is pointlessly huge, so even if the third-year classes joined in there’d still be plenty of space.

Wait, did last year and the year before have this many people staying after to practice?

“Hm? That’s…”

At the edge of the field I spot a bunch of familiar faces.

I’m pretty sure those are the ones I saw during the joint lesson last time.
So that means Class 1-A.
And in that class is—

“Come on, Kiyoto, let’s go already.”

Kirino must’ve noticed I was looking for Rinka, because she grabs my arm and starts walking, practically dragging me.

…Did her grip get stronger?

I can feel from her hand that Kirino’s grip strength has gone up a ton.

Maybe during the time we didn’t see each other over summer break she was going to cram school?

…Kirino training at cram school…
Is she preparing to attack me…?//

If that’s the case, should I invite her more often?

“…Kiyoto?”

The second Kirino grabbed my arm and started walking, that cool voice came from right behind us.

When I turn around, Rinka is standing there even though she’s pretty far from where Class 1-A is practicing.

“H-hey, Rinka…!?”

Hey, Kirino? Why did you just squeeze harder!?

“Hm? What’s wrong? Does it hurt somewhere?”

“N-no, it’s not like that.”

If I say something clumsy she’s probably gonna squeeze even harder.
…Well, that’s fine too.

“Rinka, why are you here… Gah!”

It hurts! Straight-up hurts!
It feels like my bones are getting crushed.

But that’s okay, Kirino!
Keep squeezing harder…!
I don’t mind getting marked by pain at all!
I actually welcome it!

“Are you really okay? You look like you’re holding back a lot of pain… hm?”

Rinka, who had rushed over looking worried, glances behind me.

“…You. Why are you here?”

The second she confirms Kirino’s presence, she goes straight into battle mode.

“You again~? You’re really persistent.”

Kirino turns toward Rinka with obvious annoyance in her voice.

“Looks like you still haven’t learned. You gave Kiyoto such a serious injury and yet you show up in front of me twice. And this time you’re even trying to walk home alone with him… you scum.”

“I already told you before, that whole thing is settled between us, and it never had anything to do with you in the first place, right? So can we drop it? We’re trying to go home now.”

“…You think I’ll just let you leave like this? During the summer festival I was able to hold myself back because Sister was there, but I don’t have that confidence this time.”

“Then do whatever you want. I don’t think a little sword girl who’s just slightly better than average can beat me though.”

Hey, we’re still inside the school, okay?
If you two start fighting here you’re both getting suspended or expelled.

“Just so you know, if you attack me I’ll treat it as self-defense and thoroughly smash that worthless pride of yours without holding back.”

“You’re free to talk about a future that doesn’t exist, but you’re the one who’ll end up embarrassed later.”

If someone overheard that line what would they think?
By tomorrow the whole school would probably have a scoop that “Kinui said the word ‘scum’.”

Also, even in a situation like this Rinka keeps dropping master-like lines one after another. So cool.
My dick is getting wet.
This is the real “Nuregami” right here.

“Hey, Rinka? What are you doing over here? Everyone’s waiting.”

Right when Rinka was about to take a step forward, a voice came from the side.

“…Sorry, that’s right. I took too long on break. I’m heading over now.”

Looks like the person who called out is a girl from Rinka’s class.
I always thought Rinka was the type who gets feared and stays isolated even though she’s not a shadow person, but from that conversation she seems surprisingly friendly…?

…She’s basically Ayuka’s upgraded version.

“Right. Kiyoto, your class isn’t practicing today, correct? Then how about practicing with us instead? We can use the sports center.”

I remember Rinka saying before that she wanted to train my body so I’d be ready whenever she attacks me.
If this is part of that, I’d gladly—

“If you’re gonna go that far then ye—!?”

Of course the Kirino standing right behind me isn’t gonna allow that. Before I can finish agreeing she digs her fingers into my spine and forces me to stop talking.

“Gahhh! N-never mind, I’m good.”

“…I see.”

Rinka looks unhappy again because I turned her down, but right now I can’t worry about that.

Kirino stays silent and grabs the back of my neck, then starts walking while dragging me along.

“……”

When we were saying goodbye I actually wanted to tell Rinka “see you at home,” but with my neck grabbed I can’t get the words out properly.

“……”

Rinka stares at me suspiciously the whole time, but in the end she never realizes what’s being done to me.

I can’t believe I’m getting physically threatened right in front of Rinka without her noticing.
Kirino’s gotten really good at stealth play.

And now she’s even started intentionally harming me on purpose.

…Yeah, this is exactly what a DV girlfriend should be like//

Chapter 104: The Markings Get Exposed

“……”

Even during dinner I keep touching my neck to check it.

After we split from Rinka, once we got a little away from the school gate Kirino finally let go of my neck, but her handprint stayed so clear anyone could see it.
Maybe that was part of Kirino’s plan too.

Right now I’ve got a bandage over it so it’s hidden pretty well.
…My neck is basically a free-for-all marking zone now//

“What’s wrong, Kiyoto? You keep touching your neck.”

Rinka, who usually insists on silent meals, breaks her own rule and asks me.

“I got a little hurt…”

“A neck injury? Isn’t that pretty serious? Come to think of it, you’ve had a bandage on your neck ever since Sister left. Were you hurt that long ago?”

“W-well, yeah, but… today’s is a different one.”

“What? You got hurt on your neck twice in a row?”

Oh no. The conversation is heading in a dangerous direction.

“Let me take a look.”

“N-no, they already disinfected it at the nurse’s office, so it’s fine…”

“Even so, the wound might be acting up again. Don’t worry, I have a little medical knowledge.”

For real!?
Where did you even learn medical stuff!?

Oh, right—health and PE class.
The subject that people somehow assume guys like me score high on because of prejudice.

The same people who assume we only know dirty words probably think we can’t solve any reading-comprehension questions, which is actually true.

In Rinka’s case she probably just knows the terms as knowledge, not because she’s interested in dirty stuff.

I don’t really wanna see a cool girl getting excited over dirty talk either.

“…I’m taking it off.”

Ah, ah~n, don’t touch me like thaaat~//
…Actually the way she’s touching isn’t weird at all.

“W-what the hell are these handprints and bite marks!?”

Rinka peels off the bandage on my neck and gasps in shock.

The second she says those words, Ayuka and Fuzuha—who had been quiet until now—react too.

“The bite mark is almost certainly Sister’s.”

Oh, you can tell right away.

“And this handprint… wait, don’t tell me it’s from that woman.”

Yeah, from what happened today there’s no one else it could be but Kirino.

“Huh? The handprint on Brother’s neck is from that female-gorilla side-chick?”

She got shortened even more.

“…That’s horrible.”

Fuzuha’s body trembles the moment she sees the handprint.

“…That scum woman.”

Rinka puts down her chopsticks and heads upstairs to get something.

Rinka actually stopped eating and went back to her room.
…I’ve got a really bad feeling.

“…You’re not getting excited by this, are you?”

“I-I-I-I’m not excited!”

“You’re so bad at hiding it…”

Ayuka saw right through me…

I mean, come on, getting bitten on the neck by a young lady and then having my neck squeezed hard enough to leave handprints by Kirino, who’s turned full DV girlfriend—there’s no way I wouldn’t get excited.

“Ayuka, stop it! Brother’s suffering right now!”

“Yeah? Where on that face does it look like he’s suffering…”

Ayuka is stunned by how ridiculously nice Fuzuha is.

While they’re arguing like that, Rinka comes back down the stairs.
With a bamboo sword in her hand.

“Hey, Rinka? What exactly are you planning to do with that bamboo sword?”

“Isn’t it obvious? I’m taking it to purify that scum woman.”

Purify…
Which basically means purge.

“Well then, I’m heading out for a bit. Eat dinner without me.”

After saying only that, she turns her back and heads for the entrance.

“Eh, wait—”

“Rinka!”

Fuzuha and I hurry after her to stop her.

But the one who stops Rinka even faster is

“…Let go, Ayuka.”

Surprisingly, it’s Ayuka.

“Calm down a little. Are you really the flat-chested muscle-brain chicken I called you?”

Why are you provoking her right now, Ayuka!?
We’re not in the mood for that kind of play!

“…Ayuka, normally you would also be a target for purification, but I’m sparing you solely because you’re my little sister. Don’t forget that.”

“That’s exactly why I’m telling you to calm down. You’re planning to charge into that female-gorilla side-chick’s house with that bamboo sword and beat her half to death, right?”

Even though we’re talking about something pretty serious, I almost burst out laughing at Ayuka saying “female-gorilla side-chick.”

…This might be the first time in Nuregami family history that Ayuka is the one stopping Rinka.
