How I Ended Up with an Extreme Yandere Landmine Beauty When I Asked to Hang Out with My Best Friend's Sister to Get Better at Talking to Girls

Chapter 25: The Yanderes’ Frenzy, The Strange Feeling with the Underwear

—The next day.

Thanks to my best friend’s little sisters somehow coming over to hang out in my room for some reason, there was a bunch of weird confusion, but in the end we wrapped things up after making some vague promise that I still don’t fully understand.

“Sunday… a date with those two, huh.”

On my way to school, I added the plan I made with them into my calendar app.

I never imagined that the training to get used to girls and find a girlfriend would spill over into the weekend… and what the heck even is this “Heart-Pounding Measurement Game” anyway.

On top of that, even though we played in my room yesterday exactly like Mayana wanted, because Azuri was also there I couldn’t ask Mayana anything about the summer festival… so playing in my room ended up meaning absolutely nothing.

The only good thing about it was probably getting to see those two in their casual clothes?

I have no idea why they were both wearing landmine-style outfits, but they looked really cute, that’s for sure.

While thinking about stuff like that, I walked along my usual route to school… or at least, that’s what I was doing.

“Huh… something feels off about my boxers today… they have this weird new feeling, like the fit is different…”

Maybe Mom switched them out for a new pair?

But I’m pretty sure she already bought me new ones with a different pattern just the other day…

Still bothered by that strange sensation, I kept walking all the way to school and stepped into the classroom.

“Hey! Ryoya! Morning!”

“Morning, Ryoya!”

As soon as I entered the room, Shinichi and Maki called out to me right away.

What is this feeling of relief?

Sorry to those two, but yeah… being with my two best friends really puts me at ease. I don’t have to be on guard or anything.

“So, Ryoya? How’d it go yesterday?”

“Yesterday? Oh, nothing really happened.”

“Hmm…”

“So how is it, Ryoya? You getting used to girls yet?”

“Don’t rush me. Not even close.”

“That’s right, Shinichi! Ryoya only ever had me as a girl friend, so he’s not gonna get used to it that fast!”

Maki said that while giving a shy little smile.

Why are you grinning like that, Maki?

But yesterday she was acting kinda weird and I was worried… today she seems back to normal.

“Hey, Ryoya, if things don’t work out with Azuri-chan, then like I said before, I can still introduce you to one of the girls I know—”

“No way, no way. Ryoya is a great match for our Azuri! Azuri needs to get used to guys too, so it’s killing two birds with one stone!”

“…Really? But if it starts getting tough on Ryoya, promise you’ll tell me right away, okay?”

“You’re fine, right, Ryoya?”

“Y-yeah.”

Both Maki and Shinichi worrying about me this much makes me happy… but it also kinda makes me feel bad.

I started wanting to change because I wanted a girlfriend, but all I’ve done is take advice from Azuri, and I don’t really feel like I’m growing at all.

Alright, in that case… I’ve got to at least try to take the lead and escort them properly on Sunday’s date!

“…………”

“Hm? What’s up, Maki? You’re staring at me.”

“Nothing! Anyway, once that training’s over and you feel confident enough to want a girlfriend for real, tell me right away, okay? I’ll introduce you to someone nice!”

“O-okay…”

She always says “I’ll introduce you, I’ll introduce you”… I’d at least like to pick the girl I fall for myself, you know…

Maki’s always been the worrying, overprotective type ever since we were kids.

I’ve got to make sure I actually get a girlfriend so Maki can feel at ease too.

And with that, I headed toward the Sunday date…

Chapter 26: Hanging Out with the Yanderes on Sunday (Suggestive)

——And so Sunday arrived.

At 10 in the morning, I finished getting ready and left the house.

I used to always wear lame outfits like T-shirts and shorts, but thanks to Shinichi teaching me a bunch of stuff about fashion, I finally managed to put together something that actually followed current trends.

“Weather’s good, outfit’s good… now just—”

I arrived at the nearest station, which was only a short walk from my house.

As usual, there stood two girls keeping their distance from each other: a sickly beautiful girl with black hair in twin-tails wearing the classic pink mass-produced landmine fashion, and a cool landmine beauty with very pale hair color despite being dressed head-to-toe in pitch-black landmine style.

“They really don’t get along, huh… same as always.”

The distance between them was so wide it was hard to believe they were going out to play together as part of the same group.

It seemed Azuri and Mayana had been waiting for me in front of the station.

“Sorry, you two! I made you wait!”

I hurried over to them at a light jog.

Then, like magnets, the two who had been standing apart suddenly moved closer toward me at the same time.

At this point it wasn’t even landmine anymore—it was more like iron sand.

“Ryoya-san, you’re so late〜♡”

“Ryoya-senpai… I wasn’t waiting. I just got here too.”

“Ah! Y-yeah, I just arrived right now too♡”

“Hey, stop copying me.”

Once again, the two of them were having some weird argument that didn’t even make sense.

“By the way, there’s still twenty minutes until the meet-up time. When did you two actually get here?”

“…Saito-san was already here before I arrived.”

“No, I came after Niijima-san.”

“That’s only because you went to the convenience store and came back later.”

“But Niijima-san went to the station convenience store too.”

The complicated conversation kept chaining on and on.

What is this, some kind of brain-training puzzle!?

“A-anyway, let’s just go already. We’ll miss the amusement park opening time at this rate.”

I cut off their argument and urged them to start moving.

Today the three of us were heading to an amusement park in the next city over.

According to Azuri, it was supposed to be a “one-week anniversary of starting my womanizer training” thing, so she planned a holiday date… or something like that.

…………

The atmosphere definitely didn’t feel like any kind of anniversary.

It was just aggressively tense between them.

Apparently we were going to play some kind of heart-pounding whatever game at the park, but honestly I only felt uneasy.

“Saito-san, your makeup is way too done up. Are you actually feeling nervous or something?”

“You’re one to talk… you’ve got way too many accessories on. You’re just desperate for attention, aren’t you?”

Seriously… I have no idea how this day is going to turn out.
