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 2: Yandere Landmine Little Sister Is at Max Humidity

I had zero experience with romance. To help me get used to girls, my best friend Shinichi introduced me to a girl he said would be perfect for me. I never imagined it would turn out to be his own little sister, Niijima Azuri.

The moment our eyes met in front of the school gate, Azuri spoke to me first.

Her face was like the idols trending lately—eyelashes curled up cutely, lips plump and glossy, double eyelids, the whole deliberately adorable look.
Her figure stood out even more, with a tiny waist that made her large chest impossible to ignore.

But beyond her body and face, there were several things about her that felt seriously dangerous.

One of them was how she dressed in that overly dark-cute style.

The uniform she wore belonged to Yuri ga Oka Girls’ Academy, a super elite private school in the prefecture that everyone knew about. Only girls with top grades, perfect behavior, and the right background could get in.
Normally, just wearing that uniform was enough to turn heads on the street—it was the school’s brand and pride.

Yet over that prized uniform, she had thrown on a pink sweater covered in way too many heart embroideries.
Her long black hair was tied into loose twin tails with an oversized pink ribbon hair tie, and she even had another pink ribbon at her chest.

That strong sense of self, that everything-pink fluffy vibe, somehow gave off a clear landmine warning.

“Hehe, I’m so happy we get to meet again♡ Ryoya-san. This is the first time we’ve seen each other since that day, right♡?”

The smile Azuri gave me as she spoke was so soft and melting that no girl would ever show it to a guy she had just met.

She’s seriously cute…
No, wait! That’s not the point right now!

“Um, Azuri-chan? Did you come here today because Shinichi asked you to?”

“Yes♡ My brother told me, ‘Please talk alone with my best friend, no matter what.’ When he said best friend, I kind of figured it might be Ryoya-san, so I came…and wow, it really is you♡ Between that day and this, it feels like fate.”

Azuri spoke in a sweet, spoiled tone and took one step closer with every word.
If we kept talking like this, those huge breasts of hers would end up pressed against me.
I backed away and braced myself carefully.

But what exactly is this “that day” she keeps mentioning?
When I thought about it, she had been acting this whole time like she knew me well, while I barely remembered her at all.

Shinichi talked about his sister Azuri from time to time, but his family had always been strict in all sorts of ways. Because of that, we usually hung out at parks or my house, and only sometimes at Maki’s place.

So I had never met Shinichi’s sister and basically knew nothing about her…yet it seemed Azuri had met me on “that day.”

Well, I could just ask her directly.

“Hey, um. I’ve been wondering this whole time, but what exactly is this ‘that day’ you keep talking about, Azuri-chan…?”

The moment I asked that question lightly—that instant.

“…Huh? Are you saying you don’t remember? That can’t be possible…right? Right? Right?”

Her tone lost all its ups and downs in a flash and turned into rapid speech.
The gentle fairy-like smile she had a second ago flipped instantly into a sharp, demonic glare.

Th-this is bad…!!!
It’s hard to explain exactly why it’s bad, but the air suddenly felt heavy, and if I said the wrong thing…I’d be in serious trouble.

I-I have to go along with it!
Even someone as bad with girls as me could tell that agreeing was the only right choice right now!!

“U-um, I was joking! Azuri-chan! L-long time no see!”

I quickly decided to play it off as a joke.

H-how’s that…?

“…Phew~ I’m so relieved~. If Ryoya-san had actually forgotten about me, I would have gotten so depressed I might have ●ied! You’re so mean~”

Azuri lightly tapped my shoulder as she said that.
It was supposed to be a light tap, but for some reason it felt like a heavy body blow.

“But since you do remember me, I’m really happy. Also, according to my brother, you wanted to talk with me, right? Then how about we go to the nearby Snow Tops and chat slowly over some frappes?”

“Uh, y-yeah. Sure.”

“Yay♡ Shall we go, then?”

Azuri grabbed the sleeve of my uniform and pulled me along as we started walking.

I had casually asked Shinichi to introduce me to a girl, but…were girls really this complicated?

At that moment, I still had no idea that the “get comfortable with girls training” starting today with Azuri would look incredibly sweet on the surface yet feel strangely heavy underneath.
