Human

As you know, humans are the most proliferate form of intelligent life that inhabits the world. The magical power and physical abilities of humans who haven't received training are far lower than that of the monsters. Most humans are no match for attacking monsters, and they're easily knocked down, which leads to coupling, and soon after, they're taken home by the monsters.

However, depending on training, the abilities of humans can grow immensely. Those who have received advanced training, those who have gone through many battles, those receiving divine protection, etc. are called “champions” or “heroes.” They are far more powerful than an average monster.

Although a lot of states that religion is encouraged, there are other gods and deities dispersasa worldwide, causing comienen to different religions practiced part of the "God Master." One of these lands, is the small island region, the "Zipangu Region".

The Order of God

The Order is the religious organization that reveres the chief god who is purported to be the creator of the world. The Order isn't monotheistic, there are many gods, but all of the other gods are regarded as subordinates of the chief god. Faiths that revere the other gods are treated as sects of the chief god's religion. For that reason, the majority of humans are adherents of the chief god. The majority of nations have established the chief god's religion as the state religion. Most of the human world is controlled by this enormous organization, and humans have values that conform with its doctrine. The doctrine of the chief god's religion explains how to live ones life properly as a human. Virtue lies with maintaining to be noble in character and pure of heart, never drowning in lust and other desires. Clean living is regarded as virtuous. The followers of the chief god's religion begin every day by praying to the chief god, and they continue to be virtuous, according to the chief god's teachings. They lead clean and quiet lives. And because one of the teachings says to love thy neighbor, they treat other people who are followers of the same religion with kindness. However, according to the chief god's teachings, neighbor doesn't include monsters. They are taught that monsters have been the enemies of humanity since the age of the former demon lord, they are beings who corrupt, and lead mankind to destruction.

For that reason, they are hostile towards monsters. The Order's knight brigades, etc. will aggressively attempt to slay monsters as soon as they spot them. They also form armies and try to invade the demon realm. Additionally, people called “heroes,” who receive orders to slay the demon lord from The Order, are under the divine protection of the chief god. They boast far more powerful combat abilities compared to an ordinary human, and can overwhelm monsters.
