Chapter 9 – Sibling Relationship

“Um, Arisa-san? Do you have a minute?”

At lunchtime the next day, a girl classmate approached Tsumugi with trepidation.

“Yes, what is it?”

Tsumugi put down her chopsticks and turned her gaze to the girl.

“Well, um, so…”

The girl’s gaze wandered, as if she was reluctant to speak.

As if searching for the direction of the conversation, Tsumugi subtly sensed the attention of other classmates gathering around them.

“Is it about Nii-san?”

“Heh? N-Nii-san? I-Is that person Arisa-san’s older brother…?”

“Yes. My mother remarried and Tsukishiro Takuma became my step brother.”

Taking the initiative, Tsumugi smiled.

“…No way! That scumbag is our angel Arisa Tsumugi’s brother!”

“Well, it’s better than them being in a relationship… Wait, there’s no way that could be true, right!?”

“I-I don’t believe it… I refuse to believe it. This must be some kind of mistake… Aarrgh…!?”

“Tsumugi-chan… Why wasn’t it me…? And why that scumbag of all people…”

“Oh, God, I hate this, I wish this world would just perish——!!!”

The screams coming from everywhere reminded Tsumugi once again of the bad reputation of Tsukishiro Takuma.

“Hey, are you okay, Arisa-san? Did he do something terrible to you?”

The frown on the girl’s brow showed that she was sincerely concerned for Tsumugi’s wellbeing.

So Tsumugi also responded with a gentle tone of voice.

“It’s okay. Nii-san has had a change of heart.”

“Eh? A change of heart…?”

“So don’t worry. Nii-san and I have a very good relationship.” (T/N: Ohooo…)

“I-Is that so? T-That’s good to hear…”

“Yes. I’m happy to hear that. Well then, I have somewhere to go.”

Tsumugi stood up with her lunch.

“Ah, I’m sorry I held you up.”

“No, it was nice to talk to you.”

Tsumugi thought it was nice because her classmate listened to her properly.

Tsumugi cut off the conversation and left the second-year classroom.

“Sometimes Arisa-san leaves class like that… I wonder where she goes for lunch…”

The classmate murmured curiously, not yet knowing that Tsumugi’s destination was different from the day before.

“Amazing, Takuma-kun! You’ve finally conquered the school’s number one beauty!”

After class, Yuuto was the first to speak to me.

I had been delaying going to class in the morning, and running away to the bathroom every recess, but finally I was caught.

“What the hell~ You should’ve just told me about it~ So that’s why you refused the other day~”

Apparently, Yuuto interpreted this as the reason why I refused to go to the mixer because I was occupied with Tsumugi.

“Hey, keep your voice down.”

“Oops. Sorry, sorry. I just got excited.”

Yuuto lowered his voice, but still grinning.

“So, so? How far have you gone? Have you done it already? Takuma-kun, you must have, right? How was it?”

“…..”

What a disturbing conversation.

The fact that it’s about a girl who became a step sister, and not someone else, makes it all the more disturbing.

“Well, um, I have a favor to ask. If Takuma-kun ever gets tired of her, could you pass her on to me? Just for a little while. Just a little bit, okay? Is that alright?”

“! Seriously, you…!”

Just as I was about to finish my words…

——Bam.

“Hiiii!”

My desk was hit violently, and Yuuto jumped in surprise.

“Tsukishiro Takuma!!”

It was Minase, the head of the public morals committee. Her cheeks were red, as if she was agitated, and her anger seemed to be at a high level.

“P-Perhaps you have some business with Takuma-kun!? It’s none of my concern, right!? It’s probably better if I’m not here, right!? Well then, goodbye!”

As usual, Yuuto ran away like a rabbit. Does he really consider me as his friend?

“Hmph.”

Minase didn’t even look at Yuuto.

As much as it pains me, it seems Yuuto was right. Minase stared at me with sharp eyes.

“What was that about proving yourself? Did you trick me again?”

This is probably about Tsumugi again.

“I didn’t trick you.”

“But you’re laying your hands on that girl…!”

“No, I’m not. She’s my step sister.”

“Huh? Step sister?”

“My father remarried and Tsumugi became my sister. If you think I’m lying, you can ask our teacher.”

The teacher should have already been informed.

If Minase doesn’t trust my word, I’ll give her more reliable information.

“…If you say that much, I believe you.”

Minase relaxed her tone a little.

“But… Well, um…”

Suddenly, she started to speak hesitantly, fidgeting with her words.

“Y-You’re not doing anything immoral to her, are you…!?”

“I’m not. We were just walking next to each other this morning. There’s nothing to be guilty of.”

She even linked arms with me, but as expected, I asked her to stop when we were near the school.

“W-Well, t-that’s right…!”

Minase still pressed on, as if to complain.

“Or is there some other reason why you’re coming at me?”

I think Takuma is the type of person she wouldn’t want to have anything to do with, but I think it’s because of her position as the head of the public morals committee.

I guess she thinks it’s dangerous for me to come in close contact with Tsumugi.

“W-Whaa~~~~~~~~~!!!”

As if on fire, her face, which was originally only somewhat red, is now stained red up to the ears.

“I-I don’t want to know anymore! Do whatever you want! I’ll do what I can to settle these rumors! I’m doing it for Arisa-san!”

She talked rapidly and then turned her body around.

Just after her beautiful black hair danced in the air—

“——Excuse me.”

A crystal clear voice cut through the classroom air.

“Huh? …Second year student, Arisa Tsumugi!? Why are you in a third year classroom!?”

“Eh…? D-Does this mean…!?”

My classmates must have been thinking the same thing. Everyone’s eyes were on me.

“Ah, Nii-san!”
