Cain was now ten years old. He had grown to about one hundred and fifty centimeters in height, and he had neatly arranged his silver hair and was quite a beautiful boy, just like his mother Sarah.

'I can finally register as an adventurer.'

　Cain muttered with the biggest smile he could muster.

'You'll be registering as an adventurer as soon as you can, won't you?'

　It was Sylvia who approached Cain. Sylvia has grown up quite a bit.
　She's been with me since she was born and has been working as a maid since she was twelve years old for ten years now.

''Yes. That's right!　I was looking forward to it.

　He puts on his leather armor and lowers his sword from his waist.

''Be careful. I don't expect anyone to beat you though.''

　Sylvia had watched him practicing in the training grounds he had created in the yard of his house, so she knew exactly how strong Cain was. She had been surprised at the first time when she sat back and was surprised.

'I'll do my best!

　Cain waves to Sylvia and heads through the gate of the grounds and into the city.
　The Adventurer's Guild is located near the outer wall.
　It is not good if the materials of the defeated demons are carried to the back of the king's capital, so it is installed near the outer wall in every city.
　As we walked through the city, we passed through a busy street lined with shops and stalls.
　I bought one skewer on the way and ate it as I walked.
　Adventurer's Guild is marked by a sign with a sword crossed on a shield, which is common in every city.
　The guild is on the main street, so I found it early and opened the door to enter. As expected of a guild of the royal capital, it was a larger building than the Gracia territory.
　There are about ten receptions lined up in front of the front, there are more than Gracia territory, the drinking place on the left was also busy.
　I stood in front of the vacant reception desk and waited my turn. As expected, the adventurers in line are mostly adults and well-built.

Oh, boy, did you come to register as an adventurer?　Good luck.

　A person who looked like a red-haired swordsman in line in front of me called out to me.

''Yes!　Now that I'm ten years old, I'm finally ready to register as an adventurer.

　He's a nice guy and I answered honestly.

'Okay, well, that doesn't mean you should take it easy, because you only have one life.

　He patted Cain's head and smiled at him, then immediately went to the counter as if his name had been called.

'You look like you've seen me somewhere before,'

　I thought I saw someone similar somewhere in my memory, but I just forgot about it when my turn came.
　When I went to the front of the reception desk, there was a beautiful human tribal woman, about 20 years old, sitting there. The receptionist of the Adventurer's Guild is famous for its many beautiful places. However, I had heard that she rarely came on board when I asked her out on a date.

''It's a pleasure to meet you, Adventurer's Guild Royal Capital Headquarters. What can I do for you today?

　The receptionist is polite and helpful.

'Yes, sir!　I'm here to register as an adventurer now that I've turned ten.

Then please fill out this form. Do you want me to write it for you?

I can write. Thanks.

　With that, I received a form to fill out.
　She's a receptionist who treats children in a decent manner.

　When filling out the name, there's no point in calling yourself an adventurer and a nobleman.
　Write Kain in the name, and write that his special skills are swordplay and magic. The age is of course ten years old. It seems that you only need to fill in the minimum amount.

''It's done. Please.

'Yes, it's all right. Then can you put a drop of blood on this crystal? That way, the magic power will be registered in the card.

　Cain pricked his fingertips with the needle he was given and dabbed the blood on the crystal as he was told. The crystal glowed for a moment and then a card emerged from the device underneath it. It's an iron-colored card.

It is the guild card. When you put magic into it, your name and rank will appear on the card. The materials will also change as your rank goes up, so please do your best. You will start off with G. So do we need to explain about the adventurers?

'Yes!　Please.

　I asked Millie and Nina a little bit about it when I was in Gracia territory, but I didn't ask them in detail. Come to think of it, I wonder how the two of them are doing, let's go on a 'transition' next time.

''Adventurers have ranks and start at G. As for SSS, there's only one person so far. It will only be King Yuya, the first king of this country three hundred years ago. The ranks G to F are Iron, E to D are Bronze, C to B are Silver, A is Gold, and S to S is Platinum (Mithril). The SSS rank of the first king is said to be a black card. As for promotion, the guild makes its own decisions, so we don't make it public.

　I'm not going to be able to tell you what to do with it.

I'm not going to be able to tell you what to do, but I'm going to tell you what to do. However, if a client nominates a person, the guild will review the request and then make a nomination request. As for emergency requests, there have been cases of flooding of demons in the past. As for the war with other countries, the guild will be neutral, so please use your own judgment.

　The receptionist is polite and helpful.

You'll find regular requests posted by rank on the bulletin board to the right of the entrance, so please remove them and bring them to the reception desk. However, if it's labeled as a regular request, it will be considered an accomplishment if you deliver it to us without taking the request. It's mainly about defeating goblins and the like. Also, there are cases where you can take requests solo or with a party. If you want to form a party, please register with your guild. By doing so, guild points will be added to both parties' assessments. Please note that the guild will not detect a conflict between adventurers. If serious crimes are involved, it will be involved. That's all I have to explain, if there is anything you don't understand, please feel free to ask me at any time.

'Thank you so much for being so gracious, sister!

　Cain also bowed politely and thanked her.
　I didn't even know the receptionist's name yet, so I became a big sister.

''Oh, excuse me. My name is Letia, I'm a receptionist at the King's Capital Headquarters. It's nice to meet you, Mr. Cain.''

You don't have to call me by my name ・・・・・・ I'm only ten years old, so just 'Kun', please.

Okay, then, Cain-kun, please do your best from now on. Cherish your life.

　The receptionist, Letia, smiles at me.

'Yes!　I'll do my best.

　Cain replied with an honest smile.
　They were smiling at each other, when suddenly a voice called out from behind them.

'Hey, hey, hey, when did you get into the younger hobby, Letia?　Why don't you stop acting like a little kid and leave us alone for the rest of the night, so I can keep you company? You're still a little kid, aren't you? I don't want you to come over here and help around the house. You can't just come in here, you little brat.　

　Letia-san's face suddenly turned disgusted.

　She turned around and saw a group of three rattling adventurers. One of them suddenly put a kick into Cain. He dodges it half a step off and dodges it directly.
　I didn't expect to suddenly come across something tempting. The red-haired adventurer from earlier was also a nice guy.

I'm sure you're not the only one. You're a cocky guy, you need some education.

　The other one suddenly hits me. I shift my face to dodge it, too. I've been beaten to this point.
I clench my fists to try to fight back.

'Oi!　You!　What are you doing?　Not with a kid like this!　If you want me to deal with you that badly, I'll do it for you, okay?

　I turned around and it was the red-haired brother who had called out to me earlier.

"Geez. It's Claude of the ice flame.

　One of them muttered.

Shit, you don't need that kind of grief. You little bastards.

　With that, the trio walked out of the guild.
　Cain unclenched his clenched fists.

''Thank you, Master Claude,''

　The receptionist, Letia, thanked her red-haired brother.

'Mr. Claude?　Thank you.

　Cain continued to thank him.

'It was for those guys that I stopped them. Isn't that how strong you are, kid?　Just look at the way you carried yourself earlier. What's your name?

　I think he saw me ducking earlier.

''My name is Cain. What's that 'ice flame' you were talking about earlier?

'Oh yeah, well, I'm Claude, and Ice Flame is our party name. My wife and I are playing adventurers. My wife will be here in a little while, so come join us for a drink, oh, and juice, because she's still a kid!

　As it was, Claude took Cain by the shoulders and led him to a drinking area in the back. After ordering a drink, Claude speaks to me.

'Cain, like I said before, you work out a lot, don't you?　There was no waste in the movement. That's a trick you'd have to do a lot to do.

　Claude rushes in.

'I've been training since I was a little girl, and I've had an adventurer's tutor with me.

　Cain replied honestly as well.

'Oh yeah, well, I'm sure Cain will be able to move up to a pretty good rank when he grows up, so good luck with that.

　As he says this, he hits me with a mug of the drink I just came from.

'Here's to a good meeting!'

　Then he fanned his mug.
　Of course, it was the fruit juice that came out to Cain.
　I asked Claude about the adventurer's story, and it was very helpful. I heard that the party was a two-person party and that Claude was a swordsman who used flames and his wife was an ice sorcerer. That's how they came to be called Ice Flame, and that's why they chose the name of the party as it is. Moreover, I was surprised that it was a gold (gold) rank.
　As the two of us were talking, I suddenly heard a voice from behind me.

''When I thought you weren't here, what are you doing here!　And you caught this kid!

　Standing behind Claude was a woman in a white robe with light blue hair that reached her chest and was tied back.

'Whoa. Lina, you're finally here. Cain, it's my wife, Lina!　Nice to meet you.

　Claude is hilarious because of the alcohol in his system.

'You're here at last! No, I'm not. I came here to see what you want and what are you drinking?

　Lina, by contrast, is angry.
　Cain stands once and bows his head.

''I'm Cain. When I came to register as an adventurer earlier, I got saved by Claude-san when I got tangled up with him. And I've been listening to adventurer stories until now. Sorry.

　Cain lowers his head again.

'Hmm. I didn't know that happened. Cain-kun, I think I've heard of him somewhere: ......

　Lina tilted her head back to think.

'Well, all right. Here, Claude!　We'd better get going.

　Then, I hit Claude on the head with the wand I was holding.

''Ittete. I'm sure you'll be able to find it. I'm going to go then, so Cain, see you later!

　He drank the contents of the mug he was holding and stood up.

'Thank you!'

　Cain also cheerfully called out to Claude.
　Claude walked over to the request board with his hands up in the air as he walked back.

'Oh, I was going to look at the request too.

　Cain also gulped down the remaining juice before running to the request board.
