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 21

Several days later.

Our Netora Academy Baseball Club was defeated in the first round of the spring prefectural tournament. It was a complete rout, just as expected.

Well, we weren’t exactly aiming to win.

Neither Nomo nor I took the mound; we left it to our third and fourth pitchers. We had gone through intense weight training the day before, and even with our unusually quick recovery rates, we were far from our best condition.

We had written off the spring season since it doesn’t lead to the nationals at Koshien, and our physical forms were far from fully developed. Moreover, I wanted to keep my presence under wraps until the peak of summer.

At least we confirmed that Nomo could competently handle second base, which was a significant takeaway.

The following month was a whirlwind, indeed.

The effects of our training began to show. Normally, such significant changes wouldn’t occur within just a month; bodybuilding isn’t usually that forgiving. But we’re not normal. We have an enormous testosterone secretion rate and are simply young.

Our muscles were visibly growing, and naturally, our strength was significantly increasing. Not just the weight we could lift on the barbell, but also our pitching speed, hitting power, and the distance we could hit—all were improving dramatically.

Of course, I was no exception.

While my body was already somewhat developed, making such rapid progress seemed impossible. Yet now, I am a monster with even greater testosterone levels than them. In just one month, my muscle hypertrophy, which had stagnated during my baseball days in a previous life, has now progressed explosively.

My top pitching speed is nearing 150 km/h.

And muscle isn’t the only weapon I need to acquire.

During this month, after returning home, I undertook special training in ‘amadashi.’

There was no particular reason for it, but I decided to perform it nightly in bed after my regular meetings with Maika—again, for no particular reason.

As a result, I finally mastered the technique of ejaculating in small bursts! Perhaps the muscles I developed through squats played a role.

However, I can’t exactly control it at will. It’s not possible to adjust it to something like 50 milliliters; if I tried, it would all burst out with the same momentum.

More precisely, I’ve discovered the exact timing when I can stop it, which is right at the moment of ‘byubyu’… By applying force then, it only drips ‘dara’ and can be contained.

This might seem insufficient, but it’s more than enough. The ‘byubyu’… ‘dara’… typically results in about 30 milliliters each time. That’s more than enough for a pitcher’s grip aid for one inning. (Besides, 30 milliliters of ‘amadashi’ is already five or six times more than a typical ejaculation in my past life.)

If it’s 30 milliliters per inning, even if I pitch all nine innings, it only totals 270 milliliters. Even in extra innings, there’s still plenty left. I can complete the game without a full ejaculation, using the most powerful adhesive substance without any disadvantages like energy drain or vitality loss.

The actual sensation of applying the ‘amadashi’ juice to my hand and holding the ball was incredible. The ball seemed to stick to my hand, creating a feeling of unity. It literally did stick. The sense of oneness between my hand and the ball was unparalleled.

Of course, I report all these developments to my partner Maika, but since she has been peeking at my ‘amadashi’ training from the gap in the door, these updates are, frankly, unnecessary. Riko and I often heard Maika and another girl fighting in front of my room during those days.

It seems there are no issues between Miyakotona and Nomo.

Originally, if it weren’t for the homewrecker, they’d be like a couple straight out of a romantic comedy manga about childhood friends. If I just stay out of it, they’ll naturally come together eventually.

Well, even though I say there are no issues, they still haven’t managed to make the first move. Miyakotona is shy, and Nomo is clueless—traits straight out of a romantic comedy, making a cuckold scenario extremely likely.

Particularly with Nomo, it seems my pushing him towards baseball might have made him more engrossed than usual, not really in the mood to advance a romantic relationship.

Well, as the current Yamada Kyugo, and despite feeling a bit guilty about the previous Yamada Kyugo’s actions, maybe I should push them a little.

We managed to arrange a practice match against a strong school, just as I promised Miyakotona. Thanks to the coach’s long career and my pitching videos, they agreed. Facing a pitcher with a top speed of 150 km/h is irresistible bait, especially for a powerhouse.

The opponent is the top team from neighboring Fukushima, a frequent visitor to Koshien, with this year’s squad as strong as usual. Winning here would prove that we have what it takes to compete at Koshien, enough to convince Miyakotona.

And on the day of the match, the last day of Golden Week, we arrived at a field that was simply spectacular under the bright midday sun.

“Listen, everyone,” I began, standing at the center of our team huddled before the third-base bench.

“Don’t slack off, thinking this is just a practice game. Don’t cower, thinking they’re better than us. This is a litmus test to see if we can really make it to Koshien. Think of it as the final of the summer qualifiers. After all, the environment is set just for that.”

The team members, all ears, and Miyakotona, the manager keeping score, seemed to grasp the seriousness of my words.

Winning this game, as promised, is the condition for earning her true trust.

It could mean erasing the existence of the “homewrecker” character “Yamada Kyugo” from this NTR game world for good. Maybe then my sister, who still believes this is all just a baseball game, won’t find out that it’s actually an NTR game.

So what I most want to convey to them right now is,

“We’re going to win this, everyone!”

My declaration was met with a collective roar from the team.

Great expressions. They’re full of confidence. Remembering the faces of those I betrayed in my previous life, I felt something stirring within me.

Saito, Manaka, Ohbayashi, Miyashita… I’m really sorry, everyone… I’ve been comparing you all to mere pawns in an NTR-free game.

For two and a half years, I thought I was fostering something like friendship, but upon reflection, I’ve only ever seen my baseball teammates as pieces to fulfill a promise with Riko, whether in the real world or an NTR game.

No matter how many times I’m reborn, there’s only one person who truly matters to me.

“Onii-chan! You look so cool today, Onii-chan!”

Riko…!

Next to the bench, behind the safety net, my beloved sister was cheering me on. Dressed in a tracksuit, holding her usual support fans, and hopping excitedly. She’s too cute. Too precious. I just want to hug her.

As for the other female manager, she’s currently not in my line of sight.

She’s probably busy behind the scenes, refilling water jugs, preparing ice bought nearby for icing, among other tasks. There’s a lot to be done, and I deeply respect the managers for it.

Though, if it were the usual her, she’d likely handle these tasks much more efficiently and with ease. But today, she seems strangely averse to meeting my eyes since morning, diligently handling tasks related to my nutrition but avoiding direct eye contact, her cheeks faintly blushed.

What’s going on, really? At such a critical time… Well, I have a hunch about the reason, but let’s not dwell on that now. There’s no time.

Because…

“Alright, let’s kick this off with a bang.”

The game is about to start, and I’m the leadoff hitter.

Pitching first, that’s me. My usual spot since my previous life. The coolest. The best chance to impress Riko. I’ll hit first, score first, then take the mound and hold them down. Since my Little League days, I’ve always been the most prominent and the coolest.

I was always supposed to be the coolest Onii-chan…

“…that’s why I hate you, Otani…”

He’s just too similar to me.
