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 15: Yandere Unmatched, the Tampered Memories of an Intensely Heavy Love

I ended up making a weird promise to both Azuri and Mayana, and now the two of them are coming to my house tomorrow…

When I think about it calmly, didn’t I just make a really dangerous promise?

Asking my best friend’s little sister to help me train at getting used to girls is already pretty shady behavior to begin with.

On top of that, inviting younger girls into my room…

Just thinking about tomorrow made my heart pound so hard that I sipped my tea without tasting a thing.

…Oh, this tea is actually really good.

“Let me make this clear. Ryoya-san invited me to his room because he wants me there, so Saito-san, please keep some distance, okay?”

Somehow it feels like my words are being twisted again… I didn’t invite her because she’s my “target” or anything.

“…I was the one who came first.”

“Hmm? Did you say something?”

Azuri has been completely hostile toward Mayana from the start, and Mayana keeps glaring sharply at me.

Maybe Mayana really resents that I went back on our original promise.

“To get back to the main point… Ryoya-senpai, what exactly is your relationship with Niijima-san?”

“Eh? Relationship? Even if you ask me that…”

I looked down at the tea in my cup and glanced sideways at Azuri.

Suddenly, Azuri made a finger heart at me and gave me a huge smile.

What is that supposed to mean…!?

“Ryoya-senpai? Don’t tell me…”

“No, no, it’s not anything shady! It’s just that I’m not very good at talking to girls, so to get used to it, my best friend introduced me to his little sister, Azuri.”

“Oh… I see. So Ryoya-senpai isn’t very used to women. Hmm.”

Mayana said it in a tone that made it clear she wasn’t interested at all.

Well, of course she doesn’t care about me.

“Ryoya-san? After ‘introduced me to,’ there’s more, right? There are plenty more things you could say about our relationship, aren’t there?”

“Uh, no, I think that’s pretty much it.”

“Ryoya-san! You told me, didn’t you? That you wanted me to be your training partner for life♡ And along with that confession, you gave me a handkerchief as a pledge.”

A lifelong training partner for getting used to girls means I’ll never get a girlfriend!

Is there any training that commits to failure like that!?

Also, I only lent her the handkerchief!

Everything about our conversations and memories is definitely being rewritten.

“Ryoya-senpai… if you’re able to make a confession like that, then there’s no point in doing this so-called training, is there?”

“No, I’m in this mess precisely because I never said anything like that.”

“As I thought. Niijima-san really is the type who imagines things.”

“It’s not my imagination.”

The air shifted again into one where another fight looked ready to break out.

Why do they keep having the same kind of argument over and over?

“Hey! It’s getting late, and I don’t want to overstay my welcome, so I’m heading home.”

“Ah… you’re right, it’s already turning six. Then I’ll walk Ryoya-san home.”

“N-no, it’s okay! But thanks, Azuri.”

“Ah♡”

When I turned her down, Azuri looked strangely happy for some reason.

I no longer have any idea what makes her happy or upset.

Is communicating properly with girls really… this hard?

“Thanks for the tea. See you both tomorrow.”

“Please take care on your way home, Ryoya-san♡”

“…See you, Ryoya-senpai.”

“Y-yeah.”

I half-ran out of Azuri’s room and left the dorm through the back exit.

“Phew… the gravity in that room was insane.”

The moment I stepped outside, the lightness made me feel like I could float into the sky. I was filled with relief.

But tomorrow… those two are coming to my room.

It’ll be the first time I’ve ever had a girl other than Maki in there, so I need to prepare properly…

All I can do is hope the air doesn’t get so heavy that the floor collapses.

Chapter 16: Yandere Friction and Landmine Fashion

Azuri and Mayana were coming to my room, so the next day after school, I hurried straight home and started cleaning up.

I really should’ve done it the night before, but last night I was so exhausted from everything that I just passed out as soon as I hit the bed…

Well, there’s nothing suspicious in here anyway, and I already sprayed and wiped down anything that might smell, so it should be fine.

According to Azuri and Mayana, classes end around 4 p.m., so they’d head over right after.

To begin with, was it really okay for the teachers at that fancy all-girls school to allow two proper young ladies to go to the same boy’s house like this? It felt insanely risky.

But they did say they had a curfew, so maybe as long as they kept to that, they were free to go out?

While I was lost in those thoughts, the intercom suddenly rang.

Already here? But it’s only just past 4 o’clock…

Thinking they were awfully early, I answered through the intercom.

“—Ryoya-saaan, open the doooor ♡”

Even through the speaker, I could clearly hear Azuri’s sweet, spoiled voice.

Okay, okay, I’d better go open it.

I left my second-floor room, went down the stairs, and headed to the front door.

“Sorry to keep you both wai—!?”

The moment I opened the door, standing right there in front of the entrance were… no way, seriously?

“Ryoya-senpai, sorry to keep you waiting.”

“Ryoya-san, sorry to keep you waiting ♡”

“Y-you two… what’s with those outfits?”

Yes… both of them were fully decked out in hardcore “landmine-style” casual clothes.

Azuri wore a pure white frilly top covered with tons of black ribbons, paired with a pink skirt and chunky pink platform boots.

Mayana, on the other hand, was in a pitch-black top overflowing with frills and ribbons, a pitch-black skirt, plus cool belts and jet-black platform boots. The contrast between her pale hair color and the total monochrome look was striking.

A pink mass-produced type and a pitch-black landmine…

These two were even matching as opposites in fashion too!?

“Ryoya-senpai, what do you think?”

What do I think… Honestly, I was still too shocked that they changed out of their uniforms into these outfits to form a proper opinion.

“…Y-yeah, both of you look really, really cute.”

““Huh? Both of us?””

The moment I praised them, both girls reacted with clear dissatisfaction.

“Come on, Ryoya-san. You have to clearly say which one is cuter, you know.”

“Ryoya-senpai… it’s me over this mass-produced type, right?”

Sparks practically crackled in the air between the two landmines.

They hadn’t even stepped inside yet, but my front entrance already felt like it was about to burst into flames…

Please, somebody put out the fire…!!
