Finally, I found...

　The only word that came out of my mouth from the sense of accomplishment was such an ordinary word.
　After slaying many monsters, avoiding many traps, and pushing forward, I finally found the crystallization of the dream I've been searching for - the crystallization of my dream is in front of me now.
　It's a book that sits on an altar.
　I've risked my life to get this book.

　My name is Noah Whitefield.
　I have a family name, but I'm not a great nobleman, I'm the third son of a low class nobleman who lives in the countryside. Of course, I don't own a fiefdom, I'm from a family of vassals who are only entrusted with some of the duties of the office in the fiefdoms ruled by frontier counts. Although my father is a baron, he is in effect just a mere errand boy for the frontier count.
　And I was born into such a family, and I can be said to have been born into an aristocratic family. However, can we really call a poor family that delights in having a piece of soup with a piece of meat for dinner a nobleman?
　Moreover, he is the third son, and the eldest and second sons are still alive. And of those born into a noble family, only the eldest son has the right to inherit the family. It may seem like there is no need for him to take over the family, but the heir to our family is Hal, the eldest son and heir to our family.
　That's why Ray, the second son, quickly left home and joined a knight's club, and I became a free adventurer as well.
　All in order to seek this book in front of me.

This.........is the Book of Job Change.......!

　A vocation is something that is given to us from heaven.
　Every human being receives a vocation from heaven when he or she reaches the age of 15. It is given to you in the form of the qualities you possess. I have no idea what the criteria are. There are various theories that it is something that the person was born with, or that it is based on his or her previous experience, or that it reflects what the person wants to do most, but the fact is that we have no idea. In fact, there is an example of a baker's son being given a job as a blacksmith.
　For example, a person like Brother Lei, who was given the vocation of 'knight', even if he was a commoner or a woman, could join the knightly order. That's how important this vocation is.

　When I was 15 years old, I was given a vocation from heaven.
　You will be able to find out if you are going to be given a knight, a sorcerer, or an unlikely occupation, such as a villager or a merchant, while you are trembling. No matter what kind of profession it was, I was willing to accept it if it was my calling.
　I'm sure you'll be able to find a way to make your life easier.
　I'll say it twice. I was a brave man.
　I was the brave man who defeated all kinds of evil, dealt with the demons that pervaded the world, and ultimately defeated the Demon King.
　He is the brave man whose role is always to defeat the demon king, who has appeared many times in history.
　There is only one person in the world, and if there is a person who has been given a vocation, he or she must be recognized by the country and go on a journey that will never return until the Demon King is defeated, that brave person.

　I was exempt from that at all costs.

　I had always wondered about it in the first place. Why is it always the role of the brave man to defeat the Demon King, I wondered.
　In general, the presence of the Demon King doesn't mean that there's anything detrimental about him. Defeating the demon king doesn't mean the demons will disappear, it's not like the demon king is trying to take over the world, and the world is relatively peaceful. In this country where a slightly more belligerent neighboring country is more dangerous than the Demon King somewhere far away, there is no need for a brave man. Well, I don't know if the Demon King, whom I've never met, really wants to take over the world.
　That's why I despaired. The moment I found out that I had been given the vocation of 'The Brave', I was in despair.
　The priest who performed the vocation ceremony and the friends who went to the ceremony with me were also worried about me, I was in despair.
　At best, the good thing was that the words given in the ceremony of the vocation were heard by no one but the person in question. Unless a sorcerer applies the "Analysis" (Analyze), the vocation is basically self-reported. It's a good idea to have an "analysis" of the vocation of a servant of the state, such as a "knight", and therefore fraud is considered meaningless.
　That's why I falsified my vocation. That's why I falsely claimed to be a village man.
　The priests and friends were very sympathetic. I'm not going to be the only one who can do this. When I reported this to my father, he cursed me for being so useless.
　But it was still good.
　If I declare that I'm a 'brave' person, the moment I declare that I'm a 'brave' person, I'll be on the worst possible journey that I can't return to until I defeat the Demon King.

''Huh........''

　Hence, I set out on my journey, doing my best to hide the fact that I'm a 'brave' person.
　Although I am an adventurer, I haven't registered with the Adventurer's Guild in any way. At first I thought about registering, but the guild card issued by the Adventurer's Guild would have my vocation written on it. It wasn't self-reported, but was properly analyzed. If I had registered without knowing this fact, it would have been seriously bad.
　As such, I call myself an adventurer, but I'm practically unemployed.
　The reason I set out on this journey was to seek the legendary item, the Book of Job Change, which I only heard about in rumors.

　It is the only book in the world that can change one's profession, a book that is only rumored to be found in the depths of the deepest labyrinth, in the hidden village of the elves, or in the dragon's lair.
　The historical adventurer Alexander is said to have transformed himself from a 'warrior' to the world's only 'magic warrior' by using the Book of Changes. Legend has it that he wore magic on his sword and was able to fight both demons that were resistant to physical attacks and those that were resistant to magical attacks. I've heard that there are a few others who have obtained the book of changing jobs, but no one is still alive at the moment.

　Then I thought to myself, "What if I use the Book of Job Change?
　I'm going to use the book of change, I can change this d*mnable vocation of being a brave man, if I use the book of change.

I wonder how I'll use it...

　He flipped through the pages and tilted his head.
　It's been a long, long journey to get here. At the age of fifteen, I was given an abominable vocation, and it's been almost five years since I left immediately. I've been searching all over the world without ever visiting my parents' house.
　The reason why I was able to make such a long journey is because of my power as a brave man. It's an abominable vocation, but I was impressed by the ability to face the Demon King on my own. The current me can even defeat a dragon with a single blow. With my bare hands.
　And finally, I discovered it. It was rumored to be in the depths of one of the largest labyrinths in the world.
The ruins of Rilkara - it's an underground labyrinth in a deep forest.
　In the past, Demon King Rilkara was said to have been in this land about two thousand years ago. You will find that you will be able to get a good deal more than you expected. As a result, it has become a nest for demons and adventurers to visit, but it is a devilish labyrinth where the more you go underground, the stronger the demons become.
　After all, it took me two weeks to get here from the entrance without ever leaving the building. In fact, I almost died a few times. Even I, the "brave" one, came close to dying.

　I kept flipping through the pages.
　I'm impressed by the variety of occupations on the page. In the beginning, they were all common occupations such as 'warrior', 'sorcerer', and 'knight', but gradually they became rare such as 'alchemist' and 'madman', and then in the latter half of the book, they listed only rare occupations such as 'magician' and 'dragon knight'.
　Well.
　I found it, but I don't know how to use it at all. What should I do to change my vocation?
　Oh, there's a page for 'The Brave'. It's utterly disgusting. The "Demon King" occupation is next to it. I didn't know that the Demon King was a profession.
　My hand stops at a certain page.

The first thing that comes to mind is the fact that you can't get your hands on it.

　My hand suddenly stops moving, as if some kind of compulsory magic is being cast on me.
　And as the glowing pages illuminate me, a voice runs through my mind.

--I will give you your profession from heaven.

　This is the voice I heard in that vocation ceremony.
　This is the voice that only I can hear when I receive my vocation.
　I'm going to...
　I can throw away my d*mned vocation, The Brave Man--!

--You're The Fiend Master!

　I was delighted.
　The hero, Noah Whitefield, died.
　And the new Noah Whitefield was born.
