The registration certificate is a processed recording stone. In it, information as an adventurer if you are an adventurer, or as a demon if you are a demon is recorded.
　The magic body (avatar) information is one of them.
　However, because the amount of information on the magical body (avatar) is enormous, and the magic power to reveal it must be built into the body, it requires a record stone equivalent to a registration certificate.
　That's why two sets of registration cards are basic. One is for personal information and the other is for magic body (avatar) information and magic power.

　The device that connects the spirit to the magic body (avatar) resembles a cocoon.
　There are two big white, round cocoons connected with several tubes.
　One of them is for you to enter, your personal information registration card.
　The other one is unattended, and contains the registration certificate of the magical body (avatar).
　Each one is pushed into a special insertion slot.
　All you have to do is enter the cocoon of one of them and lie down on the couch because it is like a bed.

　Then you will wake up immediately.
　It is the cocoon that was unoccupied until a few minutes ago that we will use to leave. Yes, I'm already on the move.
　The magic body (avatar) is constantly synchronized with the registration certificate, and when you leave, the memory up to that point is poured into the main body.
　It's the same when you enter the safe room and leave the dungeon.

　I was using my cocoon for the first time since I became a demon in the staff-only link room - the room where I transferred my mind from my flesh and blood to my magical body (avatar).
　His costume was essentially a black robe, but he looked even more suspicious than before. When the hood is deeply covered, it can cover up to the nose.
　Since the magical body (avatar) includes equipment, there is also a mask to hide the face afterwards.
　The most significant change is still the horns.
　They are black horns, just like the Demon King and Master.
　However, the number of horns is not two from the side of the head - it's the number of horns.

It's Remegaton. Is that all right?　I gave you what you asked for.

　She was a demon king.
　Her hair, which was as tall as she was, was tied up in one piece today. Thanks to her hairstyle, she doesn't drag her hair.
　The crimson demon king was looking at me - Remegaton - curiously.

''Yes. Ever since I decided to become a demon, I've been thinking that this is what I wanted. Thank you for making it well.

　For the first one, the Demon King's Castle covered the entire cost. After that, it seems to be half the cost.
　The magic body (avatar) costs money to create and repair it, but the demons are basically the ones that get killed.
　The demons in the first layer are usually killed every time you attack, and there is usually not enough money to pay for them. That's why many dungeons offer to cover some of the costs.
　Also, since the magic body (avatar) is basically your alter ego, the cost of creating one will increase or decrease depending on the amount of magic power you have, the size and structure of your body, and your special skills.
　Even if we say the magic body (avatar) in one word, the cost is dramatically different for the 【Brave Man】 and 【Demon King】 and other types of avatars.
　Conversely, if you're a demon placed at a lower level, even if you're defeated, it won't cost you as much money as the 【Brave Man】.

　In my case, the situation is a bit special, and the cost is actually as high as Fenix.
　When I was an adventurer, I did my best to stand around and avoid taking damage to my magical body (avatar). In fact, I used black magic to get the three front three to defeat the demons before the enemies reached the two rearguard members of Lily and I.

You're a strange guy. I'm not sure if I've ever heard of it.　A demon with one horn...

Yes, I know.

　I nodded, interrupting the Demon King-sama's words.
　Yes, I only had one horn growing from the left side of my head.
　I didn't grow one on the right.

''Mm........I see. What did your grandfather say to you?　As I recall, you made a request for a dungeon name as well.

''Haha I know it's up to the Demon King to decide.


　The Demon Lord laughed dumbly and waved his hand in a flutter.

''No, it's fine. I'm sure your grandfather is a demon king too. I had to use my own sense of taste to name the parts that weren't specified. But don't call yourself that yet?　Today you are only the Man in the Mystery Robe.

Yeah, I know.

　My job until Fenix and the others reach the tenth layer, that is - to fight off the other parties.
　The Fenix Party is, after all, the fourth most popular party in the world rank. The broadcast of the Demon King's Castle's attack was seen by many people, and they were also enthusiastic about it.
　When it comes to that, the one thing that appears is, "We can do it too, can't we? I am an adventurer who thinks that this is a good idea.
　Since the Fenix Party had already captured the castle, they could imitate its methods, even if not completely.
　They were planning to capture the first layer of the Demon King's Castle that they had captured.
　This was their intention to take advantage of the topic.
　At the time of the first layer, it's "Recommended Level 4", so not everyone can enter the castle, but the reservations are pouring in.

　From today I will be handling them to some extent.
　Apparently it doesn't have to be every time. I'm sure this is so that the preparations for the tenth layer can be done at the same time.
　The first layer is the realm of the watchdog.
　I've already thought of a plan and told them.
　Today's guests are the two hundred and forty-ninth party. He's quite capable. As a matter of course, there's no [Black Mage], but there's another warrior instead.
　He's the type of person who pushes hard with his offensive power.
　The method is similar to that of the Fenix Party, they must think that they are similar to the Fenix Party, they must think that they can break through using the same method.
　That's why they think they can break through in the same way.
　We can't underestimate the 'Impregnable Demon Castle'. We can't let Lucy-san's replacement tarnish our reputation until now.

''Now that I've been hired, I'll give you the results you deserve.　

That's very encouraging. You look completely different from your adventuring days.

　It's not exactly a full range of abilities, but at least it's nice to be able to use them as you please.
　Everyone else is already waiting in the wilderness.
　We head to the recording stone set up in the room.
　Adventurers reproduce the registration certificate for personal information in their magical bodies (avatars), but it seems that demons have that function built into their bodies.
　That's why you can transfer just by touching the recording stone. It's a bit of a strange sensation, but you'll soon get used to it.

''Sa, Sanbo!

　I suddenly heard a voice and turned around to see Kash.
　He was peeking out from the entrance of the room.
　Naturally, a smile appeared on my face.

'Good luck!

Yeah, I'll do my best.

You're that one, you should think about your tone as a Remegaton.

　I nodded at the Demon King-sama's words.

''Ah........ I wonder if it won't be as powerful as it is, I think to myself.

It doesn't have to be as extreme as Carmilla's, but you don't want to be exposed as [Black Mage] Leme by mistake, do you?

'Yes. I'll think about it.

　He waved to Kash and this time went to the recording stone.
　I moved into the dimly lit, narrow space.
　I touched the nearby wall to make sure it was clear, and pushed on a specific spot.
　Then, with a gurgling sound, a section of the wall shifts to the side.
　The light gets stronger.
　I stepped beyond the displaced wall and soon I was out in the wilderness.
　The recording stone was hidden in a large chunk of rock.
　As I exit, the rock face immediately covers the doorway.
　One [Black Demon Dog] was waiting for me.
　I stroke its head.

''Nice to meet you. .........no, uh......nice to meet you.

　I lowered my voice a bit. Hmm, it's going to take a bit of time to solidify my character as Remegaton.
　I pet the 【Black Demon Dog】 wagging its tail once more, and for the time being, I bring my voice back.

''You guys are the ones who will fight off the 【Brave Person】 party. I will only lend my strength. But don't worry, if we're together--we can definitely win.
