Kaiseki, who brought back the branches of the world tree from the village of Elves, went to seventy-three levels with his feet.

First, I went to the world tree and handed the power that Kaiseki had given me in the village to the world tree as it was.

As a result, the world tree grew slightly larger, and the spirits that were even larger in the palm of the hand changed dramatically.

The appearance has changed to a girl as young as elementary school students, and even though there are some words and a little less tongue, she can speak them.

Unlike until we empower them, it's a change that clearly reminds us of the fairies we met in the Elves.

I was then asked to name Essena, so I laughed happily when I named her.

The assistant who saw the smile,

(What a cute kid. Are you going to wake Lo...?!

It's another story I was afraid of.

Regardless, the next choice is where to bring the Essena and plant the branches of the world tree.

This was entirely up to Sarah, who came back with me.

I used magic to plant branches in the place that Serra chose so that Essena and Serra could take root on the spot.

There was no particular change in appearance, but it was said that it would need to be properly adjusted from now on if it could grow well.

It took some time for that, so I returned to management.

Two days after returning from the village of Elves.

I checked the management menu and found that it was tower LV4.

However, there was no significant change compared to the change to Tower LV3.

The addition of installations to each hierarchy and the addition of Summon Monsters added a function called "Transfer".

Regarding, it is a convenient feature that you can only transfer from the tower (the management of) to any location in the Central Continent.

It can only be used within the continent, but it is still a very useful feature, so it can be used effectively.

As always, Mitsuki brought in a consultation to study aids that were stuck in the creation of status-checking artifacts.

The seventy-sixth floor managed by Mitsuki welcomed the family one after the other by summoning the bloodsucking princess, Shreyn.

Summoning here refers to something other than what Kouchi and Mitsuki have done before.

Of course, there is a very common blood connection in Schlein's bloodsucking family, but the family members who are contracted by the bloodsucking act become the same family.

Shreyne herself said that she had never contracted for blood suction, but in that case, her family could be summoned in the same way as an ordinary summons.

In other words, it is close to the contract between Kaosuke and Ko (Fai-lone).

With those summonses, Shreyn summoned a clan to run the castle.

"... so? What are you talking about?

"Shreyn, you can't let me say" no "... so that I can come to the management team freely."

"I mean, no matter what you think, you're after my blood, right?"

"That's... okay. On the contrary, what if I didn't aim for blood?

The examiner looked like he had been poked in the face.

"... eh!?

"The seventy-third floor will become increasingly unattainable, and the fifth floor is almost ready to open, so it will be difficult for Kaiseki to just pull him here like he is now."

"... that's what it's all about, but... well, I guess so."

"So either Kouhi or I should be as free as possible, but Kouhi has an elf, so I'd better leave my hand free."

"... I see. So, what happened to Shreyne?

"That's right. And one more thing. She and Kaosuke-san have a blood contract."

"Blood contract...?

If you think of it as a study aid that you have never heard of, it feels like what it is.

"You gave her blood when she summoned you? There it is."

"Didn't you just give him blood?

"Well, she liked you, so she said she tied it herself."

"... are you okay, what is it?

Mitsuki laughed bitterly at the suspicious study aid.

"It's okay. Looks like she's your family now."

"... to?

Kaiseki shouted foolishly at the bomb that had been dropped.

"Why don't you check your status the next time you meet? I'll be clear."

Having heard the story, Kaiseki found out why Mitsuki brought this story.

A person who has basically become a family member may not greatly disobey the principal person.

It is noted, however, that this does not apply unless the act leads to the saving of the Lord's life.

Disobedience means not being able to engage in betrayal or to cause harm to one's life. Otherwise, it's just a doll to listen to.

It is a good story that you can get a new family member while it is confirmed that you will be busy from now on.

"So, what do you think? If we don't target the blood, can we get her in as a janitor?

"... uhh...!"

It was a study aid that felt buried in the outer borehole somehow with rationing.

But it is also important to have more trusted allies for the future.

"... okay. Let's make Shreyne an administrator."

"Really, Kaosuke?

Suddenly a voice that should not have been there was heard from behind, and the examiner stood up unexpectedly.

It was also empty, and the examiner was hugged by someone from behind.

I felt something soft on the back of my head, but I decided to ignore it as much as possible.

"Shh... Shrain, when did you get here...?!

"Since when did Mitsuki come here?

"Almost from the beginning...!?

Kouhi and Mitsuki didn't say anything, so it was an exam aid that I didn't realize at all.

And Kouhi and Mitsuki were smiling at the two of them.

"So, can't I join you here?

Shreyn's words, which seemed not to be too weak, stuck the study aid for a moment.

"... no... no, that's not true...

"Real...!?

"Yeah, well. Yes."

He replied that he didn't boil anything, but if he tried to shrain it, he would still be happy, and his face was broken.

"Thank you...!!

That said, I further strengthened my ability to embrace the study aid.

(Wow... wait a minute, if you put so much effort into it...)

In a hurry to study under certain circumstances, Shreyn turned into a strange face for a moment, and immediately realized the reason and smiled.

"Ugh. Kaosuke is also a man."

That said, I pushed the splendid Nikoyama back into my head.

Fuck!

The examiner looked at Kouhi and Mitsuki in a hurry, but for some reason they sighed as if they were stunned and laughed.

In this way, Kaiseki and Shreyne's defense could continue for a while.

♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦♢♦

"Iglid?

After Shreyn's skinship, which would be categorically denied as a study aid, Shreyn once again spoke his name.

"Hmm. My family is enough to manage the castle alone, but I don't have enough to think of it as all that hierarchy. Then I would like to bring us and our related species there."

"You have a connection?

"... the clan was a species that chose to spend a long time underground to avoid strife. They usually live in places that no other race can pass through. At some point, a part of the family may emerge on the surface and start living. But that's the problem."

"Problem?"

"Hmm. The clan is also famous for its distinguished appearance, unlike the Elves. Simply put, it's often described as a doll, thanks to its small body length and almost no aging appearance."

If you say so, you will also know how to study.

I can easily imagine that the leaders who target such a family are people who have such hobbies in a good or a bad sense.

"... ahh. I see. So?

"What's even more troubling, as you can see from its appearance, is that the Iglids are a very vulnerable species. At one point, one of my clans made a deal and demanded something in place of protecting the Iglids with my clan."

"... what is that?

"The blood my family needs and what they make. They've spent a long time underground, famous for their cleverness."

"... blood after all. That's what I mean..."

Shreyn seemed somewhat disappointed in the words of Kaiseki.

"By the way, perhaps Kaosuke is somewhat mistaken about us? My family certainly drinks human blood, but it's not a necessity in particular."

"... Huh? Really!?

Such a thing was a first-time study aid.

"That's right. For us, the blood of the human species is, in other words, closer to our favorites."

"Oh, is that so? I'm sorry."

"No, no, I don't want you to apologize... no, well... cohon. Anyway, that kind of contract means my family has been protecting them for a long time."

I honestly apologized and nodded while looking at Shreyn's warm and pleasant examination.

I see. Does that mean Shreyn wants to welcome the Igreeds into this tower?

"... can't you?

"No, I think it's fine. I'm also interested in what the Iglids make."

"I see...! No, thank goodness. Well then, we have to get ready to welcome them."

"Oh, hey... he's gone. I haven't been an administrator yet..."

Schlein, who left the control room momentarily, smiled bitterly.

"Sorry, Mitsuki. Can you follow me and tell me how to manipulate the transfer gate? I'll set it up as an administrator."

"Okay."

Mitsuki nodded and left the control room.

And afterwards, Kouhi and Kouji were left behind.

After all, the fifth layer of the metastasis gate was opened, and the seventy-third layer was joined by the Elves and seventy-sixth layer by the Iglids.
