I Was Not Popular With Girls in My Previous Life, but I Was Reincarnated Into a World Where Harems Are the Norm, and a Mentally Unstable Elf Beauty Follows Me Around - Chapter 9 & 10

I’ll Take Care of All Sorts of Things for You Too

The succubus who had appeared before me was the one who worked reception at the marriage agency.

Her black leather outfit resembled a bikini, leaving both shoulders bare, and the fabric was nowhere near enough to cover her ample chest. On her back were large wings. On her head were two thick black horns, and her long purple hair framed a striking beauty.

And the lower half of her body, which the reception counter had hidden back at the agency. But now it was clearly visible. Her navel was fully exposed, and the fabric was minimal. It was a wonder she did not get attacked by men more often.

“You are human, right? Human men have such a strong life force, and that is just my type.”

The succubus licked her lips while eyeing me.

She seemed familiar from comics and anime, but I recalled that succubi were supposed to be quite dangerous in the original lore. A misstep could even cost a life.

“Are you the succubus who has been attacking only low-rank male adventurers?”

“That is right. Adventurers, not just humans, tend to have more vigorous men than average. And low ranks can hardly ever beat me. So I can safely drain their life force.”

“That is just bullying the weak.”

“I am not trying to take their lives or anything. Besides, they enjoy it too, so no one gets hurt. Some men even seemed happy about it.”

“You cannot justify it with excuses like that.”

“Hmph, say whatever you want. You are E rank, right? Now let me do something nice for you.”

“How do you know I am E rank?”

“That is easy. It is written on the profile sheet you submitted at the agency.”

“No way. So what is your goal for working there? Sizing up men who come in seriously looking to get married.”

“That is a bit off. I do think people need partners in life. I want to help with that. That much is true. And while I am at it, I look for men I like. I want to get married too.”

“What you are saying makes no sense.”

“Then let us end the chit-chat.”

Right after she said that, the succubus’s eyes glowed red. I knew that glow induced the “Charm” status ailment.

Without resistance, I would have been in real trouble.

“Ufufu, how do you feel? I will take it slow from here. Come over here first.”

I approached the succubus as she commanded.

“That is it, good boy. Next, kneel right there… What is wrong? Do it quickly.”

“As if I would!”

I declared that and cast binding magic on the succubus.

“M-My body will not move…!?”

“Surprising. It works so easily.”

“That cannot be… Does that mean your magic power surpasses mine!?”

“Probably. So from here, it is up to me. Behave, and I will take you to the national knight order—”

“I have been waiting for this! I have been waiting! For someone to surpass my magic power someday!”

“Huh, what? Are you listening to me?”

“I finally found you! I will follow you!”

“Wait, how did it turn into that?”

“How? Is it that strange? For a succubus, following a man with magic power that surpasses hers is the ultimate joy and happiness.”

“Even so, it does not have to be me. I am human.”

“I do not mind at all… Oh, I see. You need proof that I will never do this again. Then I will cast a restraint spell on myself, and you order it. ‘Never attack people again.'”

Restraint magic. It was a taboo magic in this world. Originally, it sealed specified actions on another person.

Defying it brought unimaginable pain.

Because of its dangerous effects, it was taboo and said to be lost nowadays. There were even historical tales of wars between nations over the allegiance of its users.

“You do not need to do that. Just turn yourself in at the knight order.”

“Yes, I understand. But I will still cast the restraint magic. To show you I am serious. So order it.”

Judging by her eyes, she seemed genuine. In that case, I should respect her will.

“Got it. You are really sure?”

“Yes, I am serious.”

And so I ordered the succubus never to attack people again. It formed a black magic circle and melted into her body.

“Thank you. Now, will you take me to the knight order?”

A few days later, after finishing a request as usual and returning to the guild, we spotted the succubus sitting in one of the entrance chairs. Our eyes met, and I had a bad feeling.

The succubus came over to me and said one thing.

“From today, I will be in your care for life! Of course, I will take care of all sorts of things for you too.”

For some reason, she had become intensely clingy upon her return.

In the Future, That Means Marrying All Three of You

The one who approached us at the adventurer’s guild was that succubus.

“From today, I will be in your care for life! Of course, I will take care of all sorts of things for you too.”

“Wait a minute. Back then, you definitely went with me to the national knight order and turned yourself in. Why are you here?”

“Of course, I was prepared for long-term detention too.”

Then the succubus began explaining the circumstances. But she went off on tangents, like talking about a handsome guy in the knight order, so it dragged on forever. To summarize the essential parts appropriately, it went like this.

First, the knight order had already heard about a succubus causing trouble. In fact, one of their own members had been a victim.

And while this succubus had confessed, there was no physical evidence. So they took testimony from the knight order member who had been victimized.

According to that member, he had indeed been taken to some strange space, but everything after that had been consensual.

Moreover, she had never done anything harmful. In fact, he even said she had been “remarkably kind.”

Furthermore, there were no formal complaints filed. Some people had said they “got done in by a succubus,” but now it was unclear what that even meant.

In the end, the succubus had not assaulted anyone or caused any injuries. So what crime had she committed? After a few days of investigation and detention, she was released. It felt like overly aggressive flirting, perhaps.

And I knew from the restraint magic that this succubus had sworn never to attack people again.

“So that is why I decided to follow you for life.”

“If it is just joining the party, that is one thing, but for life feels exaggerated, does it not?”

“Oh, I told you before. For a succubus, being with a man whose magic power surpasses hers is a source of joy and happiness.”

In terms of monitoring this succubus, having her close by might be the safest option.

“If you mean to join the party, then I need the agreement of the other two as well.”

Upon hearing that, the succubus eyed Airi and Meg up and down, as if licking them with her gaze.

“An elf and a human. What reasons do you two have for being together?”

“Does being with someone require a reason?”

“I am adventuring with Kaito as part of my marriage hunting! Spending a long time together lets you see things that come to light, right?”

“I see. So in the future, that means marrying all three of you.”

“Wait a minute. How did you arrive at that?”

“How? Both of you… Kaito, was it? You both said you want to be with Kaito. So you have to marry both of them and make them happy.”

“That is why I am asking how it leads to that.”

“It is obvious. Because everyone can be happy that way.”

I understood that this was a world where such thinking was normal. I understood, but I could not switch so quickly from the sensibilities I had built over thirty years in Japan.

“Imagine it? Every night a different partner. Tonight it is me, tomorrow the elf girl, the next day the human girl. How does that sound? Does it not seem fun? And it does not have to be one at a time either. I would welcome that too. The possibilities are endless!”

Well, sure, I thought it was a man’s dream. But I was not thinking like a succubus! What did she even mean by endless possibilities?

“Hey, hey, Kaito, what do you think? Should we add this succubus girl to the party?”

“That is my intention.”

Meg asked me that, and I answered immediately. I thought it would be better that way, including for monitoring purposes. I had my own will too.

“I see… In that case, shall we think about it seriously?”

“Seriously? What do you mean?”

“The party house. Everyone in the party living together in one house.”

“Would it not be fine to keep staying at inns like before?”

“But do you not think it is better to cohabitate before marriage? We are strangers suddenly living together. Little things about each other might bother us. So it is important to learn those things in advance.”

“I think you are jumping ahead too much. What do you think, Airi?”

“Well, I do wonder why a succubus would join the same party. However, I like what I like. I want to respect those feelings. But if she tries anything strange with Kaito, I will blow her to the ends of the earth with ‘Wind of Ruin.’ Actually, I was prepared to do the same with Meg, but since she has a good personality, I trust her. Oh, sorry, that was about cohabitation. I am all for it.”

“Was the long speech necessary beyond ‘I am all for it’?”

Even back in Japan, I had never cohabitated, and now I was going to live with three girls all of a sudden?
