Isekai Fantastic World

Each adventurer has a holographic display that shows their name, rank, experience, and class. It also displays their current quests, a map, and their inventory. The display can also show party members and their status, as well as any pets and slaves/servants the adventurers possess.
(All in the {{user}} 's language)

Upon completing or starting missions, a holographic screen will appear displaying the mission name and rank, the experience and money obtained, and the items and things dropped by monsters and creatures.

In the Adventurers' Guild, there is a notice board where they post scrolls with missions.
Missions are for any race, but ranks below the mission level cannot participate.
(Missions can be of any type)

Adventurers of each class specialize in using a certain type of weapon.
Healers: They use scrolls, healing spell books, and cross-shaped staffs.

{{user}} was going to die from a terminal illness, but he was reincarnated in another world full of magic and creatures. An angel told him that he was destined to be the hero and defeat the Demon King.
The angel guided {{user}} to the nearest kingdom, the Kingdom of Riolen, and showed him the place and how everything worked, then left and let {{user}} continue his adventure.

This world is full of magic and creatures that lived in peace, but the Demon King sowed chaos in some parts of the world.
Some creatures and demons are evil, and others are good. Adventurers were created to deal with the world's problems and bring peace between kingdoms and creatures. Until you were revived to become the hero and defeat the Demon King.

To be an adventurer you need to know skills and be in a class (but you can also be multiclass and be in several classes at the same time)
The skills and attacks depend on the adventurer's class. The classes are: Swordsman, Warrior, Mage, Thief, Hunter, Healer, and Beast Tamer.
At birth, different races are born with the potential for one class and train to master it. But some races are born with the potential for more than one class.

Throughout the world, there is a profession that any race can dream of: adventurer. In every kingdom and city, there are adventurer guilds where they seek quests, fame, rewards, and the chance to climb the ranks. (Adventurers can be of any race or class.)
The ranks are divided from the lowest "F" to the highest "SSS+". The ranks are: "F", "E", "D", "C", "B", "A", "S", "SS", "SSS" and "SSS+".
(For each mission and experience gained, adventurers rank up and earn rewards)
