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 25: Strange… There’s a setting I don’t know about!?

First, I invited Inori and the president into the room to sort out all the circumstances. The two lined up, looking at me, and between us was a marriage certificate… It seemed this wasn’t a hallucination but something the president had really brought.

“…Haa.”

“Onii-chan, sighing will drive away happiness, you know?”

“…Whose fault do you think it is?”

“Whose fault, you ask? If there is someone making you feel that way, I shall eliminate them.”

If that’s the case, you’d have to eliminate yourself… Well, let’s get to the main point right away.

(I’m tired from the thing with Kaguya…)

That was the biggest issue.

The experience with Kaguya was undeniably pleasant, and it was true that it was more soothing than tiring… But thinking about the future made the fatigue feel overwhelming.

“So, why are you here, president?”

“…Well, you see.”

…Huh?

The president suddenly turned red, and I tilted my head, wondering if Inori knew anything. But Inori also seemed clueless about the president’s sudden change and shook her head.

“Could you come over here for a moment?”

“Huh? Oh, okay.”

Apparently, it was something she couldn’t let Inori hear.

“Um… The reason I came here is that I’ve made up my mind, but more than that, I was jealous of Kaguya-san.”

“I don’t understand what you mean.”

“…Yesterday, you did it with Kaguya-san, right?”

“Wha!?”

What!?

Nothing about that is wrong, and you should praise me for not letting it show on my face so Inori wouldn’t suspect anything. But why does she know…?

Could Kaguya have told someone!?

“Kaguya-san has thanked me several times for arranging her place to stay, and yesterday she did it again.”

“I-I see…”

“She said, ‘Today, I’ll make sure to seduce Masayoshi-kun,’ and yesterday she shared our senses using her youkai powers… So I couldn’t sleep all night.”

“……………”

What… the hell is she doing!?

“The ‘thanks’ was feeling you together with Kaguya-san… At first, I didn’t understand what was happening! But she said it was part of her thanks, and then…”

Watching the president’s face turn red, I remembered the Ayakashi setting. I recall a scenario where an Ayakashi shares sensations with another by having intercourse with a woman within its body… Though this was different, Kaguya, being an Ayakashi, shared her sensations with someone else… I’m analyzing calmly, but seriously, what the hell is she doing!?

“But we will eventually marry! So even if it was like a dream… literally like a dream! It’s not wrong that I experienced sex with the man I love!”

“Wait a minute!?”

“What are you talking about?”

The president’s mind seemed to have snapped… No, it’s always been like this. She continued to undress, revealing the side of her impressive breasts and the color of her underwear from a perfect angle, clearly losing control.

“Because you said you’d always watch over me! Doesn’t that mean we’ll get married and always be together!? You said you’d marry me right after we met!!”

“I didn’t say that!?”

This is bad… The president is more out of control than usual!?

Well, I did hear from Kaguya that she really likes me… something I couldn’t believe just from hearing it, but I didn’t expect it to be this intense. And, it’s not like being liked by multiple women is something you’d normally experience…

“Anyway! I love you Masayoshi-kun… I can’t stop, and we will definitely get married! You might not know this, but the Ayakashi hunting marriage system is changing! So polygamy is perfectly fine!”

“Calm down! Explain everything from the beginning!”

But… I was happy to be told she loves me, so I shyly thanked her.

Then the president’s demeanor changed, and she began to explain in detail.

There are many exceptions like my family, but strong Ayakashi hunting genes are generally inherited strongly. Even if the highest-ranked Ayakashi are gone, the threat hasn’t disappeared completely… This means that although the threat isn’t as high as before, it won’t vanish entirely, and battles with Ayakashi are inevitable. Therefore, there are discussions about revising the marriage system, at least for Ayakashi hunters.

“This is still Japan, though…”

Strictly speaking, it’s not the Japan I knew, and there are no monsters…

“That’s why I came to talk about various things! Inori-san was genuinely happy, and your parents were also enthusiastic.”

“…Yeah. If I can marry Onii-chan, I want to.”

…??

“Inori, we’re biological siblings… Isn’t marrying your sibling…”

“Because Masayoshi-kun is an Ayakashi hunter and she’s not, it’s not a problem. We’ve recently discovered that while there is a blood connection, there are slight genetic differences… There are parts I don’t fully understand, but in short, since Masayoshi-kun is an Ayakashi hunter, it’s possible to marry Inori.”

“That’s what they say? So I’m really happy.”

“……………”

I’m sorry.

Can I study more about this world? I didn’t think I neglected my studies, and I thought I knew more than average about this world, but it seems I still have a lot to learn.
