Yandere and Menhera - Suddenly Having a Yandere Older Stepsister and a Menhera Younger Stepsister Makes Every Day Difficult - Chapter 1 - 4

Around 4 PM, Matsuri-neesan was getting ready to pick up Ririka-chan. I was holed up in my room, regretting whether it was really okay to have agreed to this.

Ten minutes later, the front door clicked open, and Mari-nee-san and Ririka-chan came back. As I left my room to greet the two of them, Ririka-chan dashed over and jumped at me.

“Whoa!”

“Please take care of me from today on, Onii-chan!”

“Y-Yeah, nice to meet you.”

With a small body making a big bow, she let go of me and said she was going to go shopping for dinner with Matsuri-neesan, then dashed out of the house. I hurried after them to hand over the house keys, and Matsuri-neesan, noticing this, stopped.

“What’s up?”

“I-I have to go to judo practice now, so I need to give you the front door keys.”

“Thanks. Good luck!”

“Y-Yes!”

I went back inside, packed a judo uniform and a sports drink into my bag, and headed to the club. Upon entering the dojo, everyone was already assembled.

“Good morning!”

“Hey, Ryusuke, what’s up? You’re later than usual.”

“Sorry. I had some circumstances. Really sorry.”

“Don’t apologize so much. Just make up for the time you’re late. You have the potential to win nationals.”

“Yes!”

I quickly changed and started practicing. About an hour in, the dojo became noisy, with everyone looking in the same direction. Curious, we paused our practice to glance over, and there stood a beautiful person.

It was Matsuri-neesan.

I couldn’t help but exclaim.

“Matsuri-san?!?!”

“Ah, Ryusuke-kun~!”

Club members glared at us, and one approached me.

“Is she your girlfriend?”

“N-No, she’s not!”

“Really now?!”

“Why are you speaking so oddly?!”

Then, the coach approached Matsuri-neesan.

“Excuse me, may I ask who you are?”

“Nice to meet you. I’m Ryusuke’s older sister.”

“Ryusuke had a sister?”

“Ah, my apologies. I’m his older step-sister.”

“I see, I see. Well, the practice isn’t over yet, please feel free to watch. You can see how hard Ryusuke is working.”

“Yes, I’d love to!”

Matsuri-neesan sat beside the coach, her gaze fixed on me forever. The awkwardness was overwhelming, not to mention the club members were so smitten with Matsuri-neesan that practice hardly proceeded.

It was clear how beautiful Matsuri-neesan was, but what scared me more was how she found out about the club I attend.

Practice ended around 9 PM. Normally, the coach would drive me home, but since Matsuri-neesan was there, he had to take other kids instead.

“Let’s go, Matsuri-neesan.”

“Home, then. Good work today!”

“Yeah.”

We slowly walked home, and it was past 10 PM when we arrived. The moment we opened the front door, Ririka-chan was standing there, arms akimbo.

“Ririka-chan?”

“You’re late. What were you doing?”

“Judo practice.”

“…Oh. So, you don’t care if I’m scared being home alone? It’s fine if I get kidnapped?”

“I didn’t say that?!”

Ririka puffed up her cheeks, clearly upset.

I thought there was no need to be scolded since I had told her I would be at practice, but maybe if Matsuri-neesan had been at home, this wouldn’t have happened. As I pondered this, Matsuri-neesan suddenly kissed me on the cheek, taunting Ririka-chan in the process.

“Ryusuke-kun is a good boy, unlike Ririka, so it’s not tiring to be with him.”

“Onee-chan is stupid. Usually so meek and always lower than me.”

“That’s not true. Onee-chan is—”

“Ah, yes, yes. I understand~”

I felt there was some kind of problem between Ririka-chan and Matsuri-neesan as the day came to an end.

I was anxious about whether everything would really be okay moving forward.
