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 39

I was furious, something I hadn’t felt in a long time. I was running. I had made up my mind.

“Why didn’t I check properly? Am I an idiot? Damn it, I’m seriously going to kill someone!”

I had been too carefree, too arrogant. I had only considered assumptions that were convenient for me and believed in conclusions that suited me. It was too much of a convenient delusion to think that the demon of Koshien would fulfill the promises and wishes of us siblings.

“Riko! Maika! Sorry for calling you out so late! Emergency family meeting! I’m home!”

As I unlocked the door and burst into the entryway, I shouted. Then I noticed.

“…What’s going on…?”

Riko’s favorite sports sandals and Maika’s usual sneakers were missing.

I rushed to the living room. No one was there. I ran upstairs to Riko’s room. Again, no one was there.

That’s when it hit me.

“I could just call them.”

But there was no need for that.

Notifications from LINE on my smartphone. Messages from Maika. It seemed she had sent them shortly after I left the house.

Her message read:

“I just thought of this, but let’s go to Hyakunogi Maika’s house.”

“Why would you do that!?”

Without thinking, I blurted out in Nanchatte language. It seems this world has it too. Apparently, they’ve been doing the same thing in this world too. Yikes…

“Anyway, if I can’t spend the night under the same roof as Kyugo, I might as well show my face there.”

Maika would say something like this because she has been straightforward about her feelings in this world, more so because she’s been quite open in her messages since her previous life. What a cute troublemaker.

However, it makes sense. Going to the Hyakunogi household was indeed something we needed to do eventually. I think Maika’s judgment is not wrong, except for the fact that she went out alone at night. I need to be careful about that… but apparently, she wasn’t alone.

“Riko says she’s coming with me. She won’t take no for an answer.”

“Is this girl trying to mess up my engagement with Kyugo at my parents’ house?”

“Well, leaving her alone would be bad too, so it’s fine.”

“I’ll introduce her to the parents as the sister of the fiancé.”

“Oh, was I not supposed to announce the engagement yet?”

“………”

Riko… what are you thinking?

No, I see. Riko had no other choice but to act this way.

It was strange that Riko had so easily agreed to let Maika move in with us. For Riko, it was more convenient to do so, which is why she easily acquiesced—or rather, pretended to reluctantly agree.

However, with Maika returning to the Hyakunogi household, any plans Riko had would start to fall apart. The secrets she had been hiding would be revealed to us. It was inevitable.

Rather, it was a wonder that it hadn’t come to light in these two months. For Riko, such a day was something she had long been prepared for. She had prepared the actions to take and the words to say for when it would come.

Now, at the Hyakunogi household, Riko was showing that to Maika. Perhaps, she had already done so.

At that moment, my smartphone beeped with a new message from Maika.

“………”

“The parents were nice!”

(Chikawa eating sukiyaki sticker)

“Riko got along with them so well!”

“I’m so relieved! I thought Riko was up to something, but not at all!”

“So, Kyugo, don’t worry about anything!”

(Chikawa dancing sticker)

“I see. She’s lying through her teeth.”

Maika’s use of stickers isn’t because she’s in a good mood, but rather a habit from her past life when she’d use stickers to cover up her secrets. Chikawa is a cute character in this world too.

Maika had realized Riko’s secret. My suspicions weren’t wrong after all. With all these factors aligned, it couldn’t possibly be a mistake.

“Riko… you weren’t my sister after all…”

In this world, Riko, Hyakunogi Riko, wasn’t related to me by blood.

Hyakunogi Maika and Hyakunogi Riko were real sisters in this world.

All the romantic conclusions about this reincarnation fulfilling the promises between siblings were completely off the mark! What was all that romance behind the bench with Maika about? It was as if I had done nothing but spill my seed in the bullpen!

“Ah, ah? Kyugo, you’re back. What should we do, is it still good to have breakfast?”

The following Saturday morning.

Upon seeing me waiting on the living room sofa, Maika momentarily froze before flashing a forced smile.

“Welcome back, my honey. You look cute this morning. By the way, where’s Riko?”

“Stop it, it’s too early in the morning… Darling, you look cool too. The coolest in the world. Don’t make me say it! Really, Kyugo… I’ll whip up something quickly, just have some glutamine for now, okay?”

My honey fanned her flushed cheeks with her hands. Her small face and gleaming blonde hair were the most beautiful in the world today.

“Thanks, as always. Take your time. Actually, let’s take it slow for once. It’s okay to be late to practice. But really, where’s Riko?”

“Captain, you know we can’t do that. Really!”

“Really, don’t think you can cover everything up with ‘really.’ Where’s Riko?”

Maika stopped washing her hands abruptly, and without turning to face me, said,

“She went directly to the club activities from our house. Really.”

“From the Hyakunogi house?”

“Yeah. Really. Oh, it came out like ‘Let’s give birth.’ Kyaa. Kyugo, you’re naughty. Really!”

“Why is Riko, who is supposed to be a child of this house, coming from the Hyakunogi house?”

“She’s totally become like a Hyakunogi child. It feels like she’s finally accepting our marriage as my sister-in-law… I guess? Really!”

“Riko’s uniform and jersey are supposed to be here.”

“Hmm… Ah, I lent her my spare, Hyakunogi Maika’s uniform and jersey that were at the Hyakunogi house. Really!”

“They won’t fit around her waist.”

“Reallyyyy!!!”

A roundhouse kick came flying at me. It was deftly weakened just before hitting me. Classic Maika. Despite her pudgy belly, she moved like an athlete.

And with that, she finally faced me, allowing me to confront her directly. Though I really wanted to grab her belly and tease her, I might get killed for it, so I grabbed her shoulders instead,

“Tell me the truth, Maika. Something happened. Riko has been hiding something from us, hasn’t she?”

“…Riko also has some belly fat.”

“Alright. Thanks for the valuable information. What else? There must be more? Hint: the surname. Hyakunogi.”

“…Peach? Butt? Well, my butt is bigger than Riko’s… so yeah, maybe I can handle Kyugo’s overflowing libido better? Riko’s frail body might not hold up—like, she’s your real sister, so you don’t need to worry about that at all! Ahaha! Gross, really!”

“Hyakunogi Riko is your real sister, isn’t she! She’s been pretending to be my real sister ever since we reincarnated into this world, but actually, she’s your sister character, isn’t she!”

“Was it that obvious? Really!”

Maika collapsed to her knees. All I could do was look down at her with sadness.

It was confirmed…

Once again, it was driven home.

Just as initially set up, Yamada Kyugo never really had a sister.

In the next game, appearing as a sub-heroine, the erotic character from “Live Commentary! Powerful Koshien,” Hyakunogi Riko, was indeed Maika’s sister, Riko—Hyakunogi Riko.

Damn it, stuffing in unnecessary settings, you damn scenario writer! Don’t think you can provide a subtle thrill to the users with such casual connections to past works!
