Yandere and Menhera - Suddenly Having a Yandere Older Stepsister and a Menhera Younger Stepsister Makes Every Day Difficult

Dinner progressed as usual. To keep the atmosphere from getting too bad, I answered some questions and spent the time idly before returning to my own room. It’s strangely calming here, I thought, as I collapsed onto my bed, trying to sleep without thinking about anything.

Knock knock…

“Yes?”

“Onee-chan, can I come in?”

“…Sure.”

“Thank you.”

Matsuri-neesan entered the room, dressed in polka-dotted pajamas. Even so, I tried to ignore her and go to sleep. That’s when I heard the sound of something being undone. Instinctively, I bolted upright to see Matsuri-neesan stripping down to her underwear.

“Neesan…?”

“Ara, I thought you were going to sleep?”

“…It’s not about that.”

“You’re used to seeing your sister’s body, right? It’s fine. It’s a bit warm in here.”

“Please put on your clothes.”

“Ara, what’s this? You act all tough but get shy at times like this? Isn’t that gap moe?”

Matsuri-neesan approached me, a bit of drool hanging from her mouth. I pushed her away, grabbed my wallet, and ran to a nearby vending machine to calm down.

Clunk…

A can of cola dropped. I pressed the cold, chilled can against my forehead to cool down. Just as I was about to head back home, sighing,

“Ara, ara~? What are you doing out here at this time of night?”

That annoying girl from school was there.

“It’s none of your business.”

“Hey, hey!”

“Annoying!”

“Hehe. You finally looked me in the eye.”

“…What?”

“Don’t look at me with those scary eyes~. I just want to talk!”

“…”

The thought of going back home to Matsuri-neesan in her underwear was depressing. Hoping for a distraction, I decided to follow the girl.

“Fine, got it.”

“Ufufu~! Happy!”

“So, what’s your name?”

“Huh? You forgot, even though we’re in the same class? It’s Azumi! Everyone calls me Azumin!”

“Right. Azumi.”

“Hehe! Cute name, right?”

“Cute, isn’t it?”

Blushing, Azumi clenched my shirt tightly and said,

“I’m happy. Thank you.”

“…It’s nothing.”

“Hey, I wanted to talk to you about something.”

“?”

“…How about I save you from those sisters?”

“Huh?”

My sixth sense was screaming. This girl is trouble. Running away now would be too suspicious. Trying to play it off, I asked,

“Save me? What do you mean?”

“Just what I said.”

“Huh? Your tone changed all of a sudden…?”

“Well, if you’re fine with how things are, that’s up to you.”

“…What are you exactly?”

“Don’t raise your voice so quickly.”

◆　◇　◆

Azumi spoke with a frightening glare as if trying to reason with me.

“I don’t know what happened to you, but you used to be active in sports and somehow ended up at this low-ranking school. Strange, isn’t it? Well, thanks to that, I got to meet you.”

“…What do you want?”

“I told you. I’m going to save you from those sisters.”

“Shut up. I don’t need your help.”

As I attempted to flee, clutching the cola can tightly and about to run, I heard an unpleasant crackling sound from behind.

“That’s your problem. You never listen to the end. Oh, this? It’s a stun gun. I carry it for self-defense because I’m often out at night.”

“What the hell are you?!”

“Me? I’m Azumi.”

“Not your name!”

“Then I’ll change my answer. I’m your stalker.”

I was speechless at Azumi’s confession of being a stalker. I thought that was something one would generally hide. My instincts screamed even louder that I needed to escape from her, but how could I escape from a woman wielding a stun gun?

“Can you put down the stun gun?”

“If I do, you’ll run away, won’t you?”

“…Then I’ll change my question. Why are you stalking me?”

“Because I like you.”

Frozen by the confession from a woman admitting to being a stalker and holding a stun gun, my brain refused to comprehend.

Then, noticing Azumi’s face darken, I turned around to see Matsuri-neesan smiling eerily with a kitchen knife in hand.

“You’re late. I was worried.”

“Ma-Matsuri-neesan…”

“Who is this girl?”

“A… classmate.”

“Hmm. A classmate, huh? Little girl, you better hurry home before your family starts worrying.”

The tense standoff, with crackling tension between them. I was looking for a chance to slip away when Matsuri-neesan said, laughing,
