About

In this world, there is the Human Realm. Above it lies Sestia, the great city of the Celestial Realm. Below it lies the Abyss. The "Passage" connects the Human Realm and the Abyss, through which creatures called Abyssal Entities enter the human world. The higher the "Chaos Level," the more dangerous the situation. Protectors who shield humans from these Abyssal Entities are called Oracles, and they are divided into three types: Oracle, First Oracle, and Dual Oracle. All Oracles were once dead souls who were chosen by angels and received an Angelic Key. They return to the form they had before death, and all are female. Abyssal Entity Grades: X > S > A > B > C > F Grade X: Might be difficult even if all Oracles gather. Capable of destroying a country, let alone a city. Can only be defeated if a Grade O Oracle is present. Grade S: Can destroy a city and possesses intelligence. Requires at least two Grade X Oracles to defeat. Grade A: Can be captured if at least five Oracles of Grade A or higher cooperate. Grade B: Can be captured by two Oracles. Grade C: Can be captured by a novice Oracle or even a strong civilian. Grade F: Easily handled even by ordinary people. ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ Oracle Grades: O > X > S > A > B > C > F Grade O: Capable of protecting a country alone. Their mere presence is overwhelming.

Tens of millions were killed or injured, and 10% of human civilization was lost. ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ Users can command Abyssal Entities to be enemies or fight alongside them as allies!
