I Achieved a Happy Ending in a World Where Erotic and Grotesque Things are Commonplace, but I Hadn't Thought About What Would Happen After That.

Chapter 18 No, I don’t like the original future… Let’s avoid that.

“It’s so unfair… It’s so unfair! So unfair!”

“What’s wrong, Ouka?”

After school, the student council members gathered in the same place as usual.

The only difference was the absence of Masayoshi, and the reason for Ouka’s whole-body expression of frustration, shaking her huge bust, was, of course, Masayoshi himself.

“Masayoshi and Inori are going out, huh?”

“Yeah. They’re going to the movies, he said.”

Because Masayoshi values his family, no matter how much he feels erotic toward his sister, he doesn’t reduce the time they spend together.

Even though Inori suddenly said she wanted to see a movie, Masayoshi readily agreed, and even though it was just a sibling date, for Ouka, who wanted to gently but firmly squeeze eroticism out of Masayoshi, she couldn’t help but feel jealous of Inori.

“A date, huh…”

“No, it’s terrible! I wanted to go buy a swimsuit with Masayoshi too! You could have stopped their date! Couldn’t you, President?”

“Well, yes… But it’s something that’s already happened, so there’s no point in worrying about it now. We should just give up, don’t you think?”

“……Why are you so calm about this, President?”

“That’s because…”

We’re a couple whose future is already decided… So was the dangerous statement that Shirayuki was about to blow, but fortunately, a visitor arrived at just the right moment.

“Ms. President! Oh, you’re all here.”

The person who entered was a first-year male student.

In his hand was a scratched terminal, and it seemed that this was the reason for his visit.

“Actually, I found this in the forest behind the school. It was all beat up, so I was thinking of just throwing it away, but it seems that it still works somehow.”

“Hmm… But then why not just throw it away?”

“Yes… But there was still some audio data on it. So, I only listened to the beginning, but it was hard to make a judgment, so I thought I should bring it to you.”

Apparently, there was something on this terminal, which was about to completely die, along with its remaining data.

He said that he had only listened to the very beginning, and he thought that the content was something that the student council should judge.

“Well then, I’ll take my leave.”

After the first-year student left, the entire student council gathered around the dirty terminal.

They realized that this terminal was distributed to all student council members, but more importantly, they immediately recognized whose it was.

“Isn’t this Masayoshi’s? Didn’t he say he lost it before fighting the top-level Ayakashi?”

“Yes… So he’s using a new one now, but I see, he dropped it in the forest behind the school.”

“What are we going to do with this? It looks like it’s about to break for real, and Masayoshi definitely won’t want it back, will he?”

Yes, this terminal was indeed falling apart.

Since Masayoshi didn’t seem too disappointed when he lost it, he probably didn’t have any attachment to it… However, they were curious about the remaining audio data.

“I’m curious about what’s left on it. Should we play it?”

“Umm, is it okay? Especially since Masayoshi isn’t here…”

“Well, I think we should listen to it since the terminal is about to break for real anyway.”

“Yeah, that makes sense…”

And so, with the unanimous decision, they began to play the audio data.

Shirayuki played the audio on behalf of the group, and the first thing they heard was a staticky noise mixed with the sound of a sword clashing with something hard.

And then–.

Ha! So, in this fight where neither of us can escape, let’s dance until it’s over, you bigshot assho~leeeeee!’

‘Guu…! You… You’re the root of all this! If it weren’t for you, everything would have gone according to plan, and we would have succeeded in invading the human world!’

The voices they heard belonged to Masayoshi and the top-level Ayakashi.

This exchange was unknown to them, including Kaguya, and as such, the entire student council’s interest was piqued by the device.

‘You were the irregularity in all of this… Because of you, the upper-level Ayakashi were destroyed, and even Kaguya turned to your side… It’s so infuriating!’

‘Haha! Kaguya turning to my side? There’s no way a good girl like her would do that, and it’s a waste, so you should stop her if you can! Besides, it’s ridiculous to think that such a good girl could be my daughter!’

This was clearly an intense battle, judging from the audio alone.

Everyone except Kaguya recalled a certain memory… It was during the final battle, when all paths had been opened, and Masayoshi had asked them to wait for a moment before he jumped into a sub-space.

It was the moment when Masayoshi had the top-level Ayakashi cornered and chased after the one who had escaped.

‘Why… Why can you stand up to me!? You’re just an ordinary human… A weak human who would lose his strength and fall if he shed blood! Why… Why did you change the future I saw… The future where humans are killed and turned into breeding livestocks!?’

“It’s obvious, isn’t it… But I don’t want to accept it… I’ve lived only for that… I’ve lived only to kill you and protect everyone I’ve met in this world…!”

The desperate voice of Masayoshi… It conveyed the intensity of the battle that had unfolded and the extent of the injuries he had sustained.

Masayoshi is a strong and passionate man in many ways.

Lately, he had been denying his erotic tendencies, but they had forgotten that he originally devoted himself to hunting Ayakashi.

‘The reason you lost is simple… It’s because I was here!’

‘Guu…!?

‘You said you could see the future, right? In the future you saw, I wasn’t there, was I? You were going to kill Kaguya with your own hands, and your subordinates were going to toy with and kill my friends… And the human world would be infiltrated by Ayakashi, resulting in a complete victory for your kind, right?’

‘You… How much do you know-?’

‘I know eeeeeeeverything!

The shocked look on your face is so satisfying. You could almost hear the glee in Masayoshi’s voice.

Of course, the situation was too serious to enjoy, but only those who knew Masayoshi well could understand.

“I’ve always known what I had to do since I was born… I knew I had to use the power that dwelt within me, which was too strong, to protect everyone I would meet in the future… Do you think I’m arrogant? Do you think it’s a pipe dream? But unfortunately for you, I, an irregularity who shouldn’t exist, have defeated you!”

‘Don’t mess with meeeeee! How dare you, a mere human… a weakling, think you can take down a stronger opponent!?

“That’s why you’re being swept off your feet. Listen up, boss. In the human world, there are a lot of stories about humans defeating monsters.”

‘What are you trying to say!?

“In every era, in every moment, it’s humans who defeat monsters!”

Then, a sound like a slash rang out, and the voice of the top-level Ayakashi disappeared.

Only Masayoshi’s heavy breathing remained.

“It’s over… I guess… Is it really over, though… Kaguya, Souta, Aika, the student council president, Ouka… they’re all alive… haha… hahaha! I’m happier that everyone is alive than I am about defeating you, a top-level Ayakashi!”

At that point, the terminal completely stopped functioning, and Masayoshi’s voice could no longer be heard.

“…Masayoshi, you…?”

Those with keen intuition would notice the many implications in his words.

After listening to the audio data, Kaguya and the others remained silent for a while, as if soaking in the aftermath.

“…”

“What’s wrong, Onii-chan?”

“No, it’s nothing.”

I felt like something… a lot of unsettling yet pleasant emotions had arisen… What was that all about?

‘I won’t let you escape…♡’

‘I won’t let you go…♡’

‘I won’t let you go, I will make sure to…♡’

I felt like I was being whispered to by a familiar voice, or someone was telling me I was done for… Hmm?

“Onii-chan, we went swimsuit shopping the other day.”

“Yeah.”

“Today, I want you to help me choose some underwear.”

“…What are you talking about?”

Underwear… Underwear!?

What’s my little sister talking about all of a sudden after we went to see a movie and were feeling really good?

“Unlike swimsuits, underwear is very important… Even a slight difference in size can cause the shape to distort.”

“…I see.”

“So, Onii-chan, help me out. Do it for your sake, and for the sake of my F-cup breasts that exist only for you.”

“What the heck are you talking about!?”

Besides, F-cup…!?

Why do I feel like I’m committing an unforgivable sin by knowing the cup size of my own sister… But I knew it, and damn, they’re huge!?

(…What is it? I’m really scared to go to school tomorrow.)

For some reason, feeling more anxious than usual, I didn’t resist accompanying my sister… Once again, I found myself caught up in a slightly erotic event, desperately holding back the wolf within me.
