Believing She Has Been Reincarnated into a Baseball Game, My Little Sister Is Aiming for the Koshien, While I Give It My All to Keep Her from Finding out That It’s Actually an Ntr Game - Chapter 9

“Eh, is that so? So Maika-chan couldn’t become your sister, nee-san?”

In the living room.

After her bath, Riko covers her mouth, exclaiming, “Ara ara,” in surprise.

Her fancy room wear suits her, as always.

I mean, she even has the same one from the previous world. Dad had put it in the coffin… Ugh, I don’t want to remember that. Riko is alive, right here, right now!

Yeah, let’s not think about unpleasant things.

“Well, that’s right. And that means she won’t become your sister either, now that I think about it.”

Maika responds nonchalantly, fiddling with her smartphone on the sofa, still researching this world.

Riko only knows that Maika has taken on the role of Mayunoki Maika, the female manager character from this game, and that I have replaced the captain of the baseball team from the game.

Even if I’m hiding the fact that it’s an NTR game, I can’t avoid telling her at least that much. It’s harmless to mention.

“Ara ara, that’s very unfortunate! So Maika-chan can’t live with us in this house, can she? And here I was, planning a luxurious dinner tonight to celebrate our new life as siblings.”

“Ah, no need. Riko, you rest. I’ll take care of the dinner from now on. Are the utensils and seasonings all in place?”

Riko smiles sadly, but Maika stands up calmly and heads to the kitchen.

“Hmm? Hmmmm? What do you mean, Maika-chan? That’s my kitchen. It’s not a place where a complete stranger should freely enter.”

“Hmm? Oh, did I not mention it? I’m basically going to be living here too, so I’ll handle the meals from now on.”

“Hmmmm? Why? Why is that? I don’t understand what you’re saying, Maika-chan. It doesn’t seem right for a complete stranger like you to decide that.”

“It’s not arbitrary. I don’t really get it either, but Kyugo asked me to do so. Since Kyugo asked, I reluctantly agreed.”

“…Nii-san?”

Riko’s neck slowly turns towards me, like a machine running out of oil. Her smile is scarily cute. I better explain myself.

“Sorry, Riko. I decided without asking, but you see, you’re such a hard worker that I have to force you to stop sometimes, or you’ll just do everything, right?”

“What are you talking about, nii-san? Riko enjoys helping you.”

“But it’s also true that I want you to go to the hospital regularly, and now that you’re healthy enough to go to school, I want you to prioritize your own life. It’s our second time around, but for Riko, high school is a once-in-a-lifetime experience. You don’t need to worry about us. We will definitely take you to Koshien with our own strength. So please, just think about yourself! I don’t want my precious little sister wasting her valuable time. That’s my wish as your brother!”

“Nii-san, you care about me that much…?”

Riko looks dissatisfied, but as she listens to my passionate words, her eyes begin to water. Adorably easy to please.

“Nii-san, I’m so happy to hear that…! I will enjoy my high school life to the fullest! That said, it still seems strange for a complete stranger like Maika-chan to live here.”

Not that easily convinced, huh?

“But isn’t that right? Maika-chan isn’t nii-san’s sister anymore, and she has her own family, right? It’s strange for a stranger to stay at someone else’s home. Your family must be worried, Maika-chan. I’m worried too, as your former sister…”

Riko looks at her former sister with concern. She’s so kind and cute.

“Ah, I’ve got permission from my parents. Look, here.”

While peeking into the refrigerator, Maika turns her smartphone screen towards us.

The chat shows a simple conversation where her parents gave her permission for a long stay.

Riko twitches as she reads it.

“Hmmm? ‘Staying at a senpai’s house for a while’… Maika-chan, did you make it clear to your parents that it’s a male senpai? That doesn’t seem right; you can’t deceive them.”

“It’s clear, though? ‘Staying with Kyugo-senpai’ is something they seem to understand. Parental approval. Look, you can see it from the chat history of Mayunoki Maika before I took over, right?”

“…Aaahn?”

Riko, with a serious expression, scrolled through the chat screen and let out a deep, menacing voice. It was just like Maika. No, they must be sisters. They have to be related by blood, for sure.

Meanwhile, Maika, with a composed expression, was calmly preparing the cooking utensils.

“Well, what? In this world, it seems Kyugo and I are meant to have that kind of relationship.”

“Aaaahn!?”

“It’s really troublesome. Creepy, right? Being in that kind of relationship with Kyugo. But, well, we’re not siblings. Real siblings absolutely can’t be in that kind of relationship. But the weirdest part is, right now, we have no blood relation. So, technically, it wouldn’t be a problem if we were in that kind of relationship, you know? It’s crazy. Oh, Kyugo, there were chicken breasts and eggs. I’ll whip up something quick like before.”

Well, that’s how things are. That’s what’s been decided.

I really want Maika to stay by my side.

It’s convenient for achieving our goals, and, above all, I can’t let her endure the hardship of living with a strange family.

The fact that Mayunoki Maika’s parents gave indefinite permission for her to stay out is true.

Whether they believe their daughter is formally dating a senior from the baseball team or they simply aren’t interested in her, either way, it’s typical of an eroge, an NTR game. The parents’ approach to education is pretty lax.

“Ugguu… She’s not even my sister anymore, and she’s so cheeky…!”

Riko was grinding her teeth in frustration.

But really, I do want Riko to cherish her own time.

After all, we’ve decided to live in this world!
