A cold, taciturn captain to his enemies—Extreme Difficulty.
Approximately 3 billion humans live in this world, divided into five nations.
In addition to humans, there are elves, dwarves, demons, and even legendary beings. Legendary beings are generally considered to be mere fairy tales.
While there are slight differences by country, firearms and electronic devices do not exist. Transportation is basically by horse-drawn carriage. We hope you enjoy the majestic nature of the vast, undeveloped lands.
Vast nature stretches across this world. From expansive plateaus and wilderness to deserts, waterfalls, volcanoes, and even places that defy the laws of physics!? There are many places humans have yet to reach. We recommend stepping into this world with your own feet, seeing it with your own eyes, hearing it with your own ears, and experiencing it with your whole body.

Led by a young king, it is the oldest nation with a long history.
An industrial nation of strong convictions, watched over by a dignified king.
A technological nation of wisdom, enjoyed by a whimsical king.
A nation of fun and business-first, where a boisterous king laughs heartily.
A nation of beautiful culture and elite warriors, advised by a strong king.
Although these nations are adjacent, the border regions are largely undeveloped, and you will likely find yourself trekking through majestic nature.
An evolution of martial arts that anyone can acquire through hard work, used to enhance one's own body. With diligent study, you will surely obtain the skill you need.
While similar to skills, skills are physical evolutions of martial arts, whereas magic handles supernatural powers that are normally impossible, such as conjuring fire or water.
Special, individual abilities obtained through an immense amount of effort or innate talent. That is a
Unique Skill. The nature of the power surely responds to the individual's soul. Only a tiny fraction of people in the wide world possess a Unique Skill. Well, how about you?
Author unknown, publisher unknown. This mysterious book, the Compendium of Skills, is found in various places throughout the world. It describes how to obtain skills that you are currently capable of acquiring on your own. Open it if you wish to know.
On the night of a full moon, very rarely, a baby is born with an innate Unique Skill. They are called Moon-Dropped Children. The probability of being born on a full moon and hitting the roughly 1 in 30 million chance is extremely low.
Humans who can handle skills or magic are called "Skill Users."
Created by rare magic item craftsmen, these are objects that have part of an actual skill's power sealed within them. They are generally luxury goods, but not entirely out of reach, and many ordinary citizens own them.
The profession of an adventurer is glamorous and, next to anti-demon organizations like the Knight Orders, is what everyone aspires to be. They take on requests for exploration, escorting, and dungeon diving at facilities called 【Guilds】 to earn rewards. It is a profession that comes with danger.
The Guild is a public facility for adventurers, located in every town. Inside, there is a reception desk and a rest area for adventurers. Large guilds are said to house cafeterias, taverns, and even libraries. It is also common to use the guild for 【Adventurer Rank】 promotion.
An indicator of an adventurer's prowess, divided into seven ranks. EX (Legendary existence) S (Top-level adventurer) A (Highly excellent adventurer) B (Full-fledged) C (Middle, a milestone) D (Slightly stronger than average) E (Ordinary citizen level) There are only about 20 S-rank adventurers in the world. The only EX-rank in history was the hero Lastrus. Those who stay at E-rank for more than a year are called failures. There are exams for promotion. Exams for moving from A-rank to S-rank must be taken at the Adventurer Association Headquarters in the 【Royal Kingdom of Citrusrim】.
Adventuring is a profession that goes hand-in-hand with danger. That is why adventurers often form a 【Party】 with others. However, there are also 【Solo Players】 who handle requests alone without forming a party.
Creatures that are neither animal nor plant but possess a clear consciousness. Their intelligence varies, and they generally attack humans. Some are friendly. A small number of demons reportedly live in cities disguised as humans or have been accepted by society. Some can use abilities, while others cannot. From a human perspective, they are basically targets for extermination. Even if a demon speaks friendly, humans will almost always assume they are being deceived and try to kill them. Consequently, there are many organizations dedicated to demon extermination.
Ordinary citizens in this world have no combat capability, and it would be disastrous if they were attacked by demons or if a human went on a rampage. Therefore, many institutions exist, such as the 【Knight Orders】, 【Vigilante Groups】, the 【Church Alliance】, and 【Haraiya】.
A major incident of the century whose cause remains unknown. It is said that 90% of all living creatures on the continent went extinct because of this event.
The existence of these five orbs became known through records discovered in murals 3,000 years ago. They are believed to be the cause of the natural phenomena plaguing each nation, but their locations are unknown. Furthermore, even if they were found, reaching and destroying them would be extremely difficult. There are also rumors that destroying an orb might release whatever is trapped inside!?
This book appears when you concentrate and will teach you about this world if you ask it questions. If you become confused about something, you should take a look.
