I paid off the debt for the most beautiful sisters in the school, and then they barged into my house where I live alone. “Please go back home; you don’t need to repay the favor.” “No way.” “We don’t want to~☆”

Chapter 9 - Beautiful Younger Sister Attacks



The following day.

Kamishiro had mentioned that she would be stopping by the store after school, probably to pick up various items for her sister, who would be coming to our house today.

I’ll need to increase the living expenses to include my sister’s share. But I have a feeling Kamishiro won’t accept it.

Ah, before that, I need to prepare a futon for her sister. Maybe I’ll ask Mr. Higashi to buy it for me again.

With these thoughts, I arrived in front of my house from school.

And then, someone was standing in front of the entrance?

“………………..”

Whoa! I was momentarily captivated.

Even from a distance, her appearance was striking.

A young woman, or rather, a girl in a school uniform. Fairly tall, with light-colored hair, perhaps due to a lack of pigment. Moreover, her long hair made her stand out even more.

Above all, her style was extraordinary.

It was as if a model was standing there, an out-of-place spectacle in front of my house. But why in front of my house?

“Ah.”

Noticing my presence, the model-like girl turned around.

She walked towards me with light steps.

“Hey, big brother, are you Kagami?”

“Eh? Ah, yes, I am, but…”

“Oh, I knew it! You look more ordinary than I thought? But they say you can’t judge a book by its cover.”

Wh-what’s she talking about? Up close, she has an imposing presence.

The more I look at her, the more her intense beauty strikes me.

I might even describe her beauty as startling, unlike anything I’ve seen before.

“Ah. Who are you, exactly? What brings you to my house?”

In response to my question, she looked puzzled and tilted her head. Her movements were very cute, considering how beautiful she was.

“Huh? Didn’t you hear? I’m supposed to be living with you starting today.”

“――What?”

Today? Living with me? Wait a minute…

“I’m Kamishiro Erika, Karen’s little sister! You’re the one who helped us, right? Nice to meet you!”

The girl, who introduced herself as Erika, leaned in close as she named herself.

She was tall, so even at my height of just over 170 centimeters, her face was right below my line of sight.

Wait, what!? She’s in middle school with that appearance!?

“Hey, Erika, didn’t I tell you to contact me before coming and to greet me after we met up?”

“Come on, it’s fine. I wanted to meet Kagami-san and see my sister soon. I missed you, big sister~ Hug~”

“Hey, Erika, don’t just hug me all of a sudden… Oh, my.”

After inviting Erika into the house and waiting for Kamishiro to return, the moment her sister arrived home, she jumped up from her chair to hug her.

The passionate embrace showed that they were quite close as sisters.

However, since the younger sister was taller, it looked like their roles were reversed at first glance.

“I’m sorry, Kagami-kun. Did this girl cause you any trouble? She’s a bit… different, shall we say.”

“Boo~. I think my sister is just too serious.”

While I agree that her sister is overly serious, I also understand that Kamishiro’s younger sister is free-spirited.

I was bombarded with questions while waiting for Kamishiro, and it was exhausting.

“Hey, hey, were you living alone, big brother? Isn’t it strange for a high school student to be rich? Isn’t it dangerous? Why?”

“Ah, do you have a girlfriend? Even if you don’t have one, tell me your type!”

“And, to be honest, what do you think of my sister?”

“Actually, do you like her? Were you targeting her? Huh, you’re not? Really, really?”

It was indeed tiring.

I mostly brushed her off since it was tedious to answer seriously.

“It wasn’t really a bother.”

It was a nuisance, but it couldn’t be helped.

From her sister’s perspective, it’s natural to be curious about the person who’s employing her sister.

“That’s good. Then, let me introduce you again… Oh, before that, let me put the groceries in the fridge.”

“I’ll do it~”

“Really? Thank you. I’ll make tea in the meantime.”

After a sigh of relief, Kamishiro hurriedly went to the fridge, with her younger sister quickly joining in to help.

Perhaps it’s natural for sisters, but their collaboration was incredibly smooth.

The two finished their teamwork in the blink of an eye as I sat and watched.

Now they were both seated across from me, with tea in front of them.

“Let me introduce you again. This is my sister, Erika.”

“I already told you, but I’m Kamishiro Erika. Nice to meet you, big brother?”

With a cheerful smile, Kamishiro’s younger sister inquired.

Kamishiro seemed to relax too. Maybe having her sister next to her is comforting.

“Ah, I’m Kagami Seiichiro. I suppose I’m your sister’s employer for now. Nice to meet you.”

“Sei-chan, right! Nice to meet you!”

Sei-chan!? The last time I was called that was by my grandpa when I was a child. He used to call me “Makoto.”

“Hey, Erika. It’s rude to call him that all of a sudden.”

“Aw~? Really? Is it bad, big brother?”

Kamishiro’s younger sister asked with a genuinely innocent expression. The gap between her appearance and her gestures was quite powerful.

“You can call me whatever you like; it’s fine.”

“Yay~. Ah, but I’ll call you ‘big brother.’ I never had an older brother, so I wanted to try calling someone that.”

Isn’t it wild to call a complete stranger “big brother”?

Maybe Kamishiro’s younger sister has high social skills. Perhaps she’s more casual than her sister?

But no matter how casual or younger she may be, I must address her properly. I owe her an apology.

“I’m sorry. I kept your sister here all the time. I didn’t consider that you’d be alone in the apartment.”

“That’s all my fault.”

“Ahaha, it’s fine~.”

My apology was interrupted by Kamishiro’s younger sister.

“I was often alone because my sister often worked part-time, and Mom was hardly ever home. And I knew this would happen when I heard about it.”

“Is that so?”

“Yeah. My sister was so determined to repay the person who helped her!”

“Erika!”

Kamishiro tried to stop her, but her younger sister’s revelations continued.

“My sister tends to go all out once she decides something. So I knew she wouldn’t come back halfway. Even visiting Mom in the hospital, she said she couldn’t go, so I should go.”

Visiting her mother in the hospital!? Was she planning not to go even for that…?

I looked at Kamishiro in astonishment, and she subtly averted her eyes.

“I never asked you to do that, nor did I intend to?”

“Yes, I know. But I understand why you’re doing this. You’re doing it for me too, right?”

With a gentle smile, Kamishiro’s younger sister embraced her sister.

The two looked so close. It was a beautiful sight.

“Thank you, Erika. But you don’t have to worry about me. I’m fine. I’ll do my best to make sure you can live well.”

“Yeah, I know. I trust you.”

Their conversation was heartwarming.

But, as a third party, I had to say something.

“It’s only for a short time, but let’s get along.”

I extended my hand to Kamishiro’s younger sister.

“I’m looking forward to it, big brother!”

With a cheerful smile, Kamishiro’s younger sister grasped my hand firmly.

It was a strange feeling. It’s been a while since I interacted with someone like this. It was also a refreshing experience to meet someone who could speak so openly with me.

Our life with three people had begun.

It was a lively start, but how would it turn out? Only time would tell.
