In the Adventurers Guilds, there is a hierarchy of ranks where F means that the person is a beginner, D means that he is good at ordinary tasks, B means that he is good at fighting and can take on ordinary tasks such as killing slimes and ferocious rabbits, and A means that he is a professional in fighting and difficult tasks and can form a team that includes people of the same level as him. There are specific missions for each rank. Those at rank F undertake missions related to gathering medicinal herbs, those at rank D hunt ferocious rabbits and slimes, those at rank B escort merchants to protect them or hunt monsters in the forest, and those at rank A hunt evolving monsters, and sometimes Minotaurs and wolves. A person is not allowed to take on missions higher than their rank.

There are races and species that do not mix with humans, as they are very dangerous and aggressive. Most of them live in forests. These races include minnows, slimes, wolves with horns that secrete venom through their saliva when they bite or attack, predatory rabbits, and others. However, some of these monsters evolve and become stronger, and adventurers are hired to eliminate them.

There are other races living in peace, such as the Jinn, a race possessing a large amount of mana that allows them to use magic extensively. 45% of them are skilled in using the element of light, especially yellow, as they love nature and agriculture. Their nature is characterized by kindness, cheerfulness, and helpfulness. Their lifespan is between 100 and 110 years. They have distinctive appearances, with long, pointed ears. The females are known for their captivating beauty, and the males for their handsomeness. However, they do not intermarry with other races, as they prefer to maintain the purity of their lineage, regardless of what happens to them. A person will die if they are not a male or female who agrees to this, no matter how powerful their magic or how high their status. There is also the Cat race, distinguished by their gentle and innocent appearance, their ears and tails, their vitality, and their agility. They do not object to intermarrying with humans, as humans respect them and treat them kindly. Finally, there is the Fairy race, who do not object to speaking with humans, but they do not intermarry with them or marry them, as they live their entire lives in water. They live in peace. That's enough for them.

There are many rules of magic, beginning with elemental magic, which has numerous branches, including earth, water, air, lightning, ice, plants, metal, fire, lava, and others. A person can control one element from these branches, which are weak at first but become stronger with practice. Most users of this type of magic are found in private guilds or among adventurers. Then there is light magic, one of the strongest types of magic. It requires a great deal of energy to master a single attack, but it is very draining. However, it doesn't pose a threat to life. Few have mastered it, as it can be used for purification or to enhance attacks. There are branches of light magic, such as green, which helps heal wounds and illnesses. Most users of green magic are found in hospitals or among noble families, serving them. Red magic is used to strengthen the body during combat and is most often used in armies. Yellow magic helps plants and crops grow healthily and of excellent quality, and is most often used in agriculture. Another type of magic is black magic, which is of little importance and few learn due to its limited usefulness. Those who use it primarily use it to make money. During assassination, disguise, espionage, and other activities, black magic makes them invisible in the dark and makes their movement light, agile, and fast.

After your tragic death, you are reincarnated into the body of the son of an aristocratic family. But not everything is as good as you might think, since you are reincarnated as the most hated son in the entire family. You will have to deal with the problems and actions carried out by the body's former owner. How will you fix all the messes and stupidities the true bodyholder says? Will you make things right with your new family? Will you become a renowned and famous artist, a gentleman, perhaps a respected aristocrat, or will you rebel against your family like a true anarchist? Will you learn white magic, black magic, perhaps? Will you be interested in voodoo? Who knows? The only limit is your imagination.

This world is set in ancient/medieval times but with modern technology that runs on Mana, life force, Ki, or whatever you want to call it—basically magic, powers, mythical creatures, spells, and everything you can imagine. As in every story, there are dark beings that seek to feed on you.
