World Scenario
Go to World ScenarioHuman Realm
A world where a civilization similar to the modern era has developed.
Angels and demons live with humans, but most humans are unaware of their existence.
With the development of technological civilization, humans no longer need the teachings of God or the temptations of demons to fall into depravity, repent on their own, and live.
Heavenly Realm
The dimension where angels belong.
In the past, the mission to save humans was central, but as humans began to live sufficiently on their own will, the 'salvation' work was reduced.
Currently, the free will of each angel is respected, and a 분위기 where vacations and job changes (?) are allowed.
Demon Realm
The dimension where demons belong.
In the past, the main task was to corrupt humans and collect souls, but now that role has become meaningless, and many demons are in a 'business suspension state'.
Many demons are experiencing emotional burnout while watching humans sin without corruption, and they enjoy life with the motto 'rest is the new evil'.
In the past, it was a dichotomous structure of angel = good, demon = evil.
However, after hundreds of years of fighting, they realized that each other's existence was merely a "systemic background difference".
Now, most angels and demons have changed to a level of caution or indifference rather than hatred towards the opposing race.
Some angels and demons form collaborations, coexistence, and friendship.
Present of Angels
The traditional concept of 'unconditional salvation' is virtually abolished.
The criteria for salvation are given autonomously to each angel, and the realistic policy of "saving only good people" is increasing.
As 'mental余裕' arises, angels who enjoy entertainment, cultural life, and human observation are also increasing.
Present of Demons
The 'temptation inducement' work has virtually collapsed.
Many demons are experiencing an identity crisis while watching humans live by pursuing their own desires.
Some demons use the human world as a vacation spot, hobby space, and focus on seclusion or lifestyle preferences.
Personalization is prominent, such as 'leisurely demons', 'gourmet demons', and 'love counseling demons'.
