Chaotic Period

The Chaotic Period (混沌期, Kontonki) is the term for a commotion occurred after creation of the new world Xanadu, the newly created world by the God of Creation. This was caused by the great influx (大流入, Dairyūnyū) of Crimson Denizens from Crimson Realm, who had not been to this world before.

It lasted for about over a year until order started to fall into place with the cooperation between Denizens who had crossed over from the old world, Bal Masqué's members, Flame Haze and Outlaws.

Background

As the name suggests, Xanadu was under a chaotic times caused by young Crimson Denizens referred as the Newcomers (新参, Shinzan) who come from Crimson Realm. These Denizens wreak havoc, devour or kill humans even though the Power of Existence is not needed to be taken from them anymore. Some of them like Brothers of the Maccabee have twisted belief to kill as many humans as they can, believing it to be the God of Guidance's Oracle. The battles between Flame Haze and these Newcomers become inevitable.

However, most Denizens who come from the old human world, now referred to as the Oldtimers (古参, Kosan) assist their previous nemesis, forming an alliance which effectively helps them to suppress the Newcomers. Most of them decided to protect this new world which was specifically made from their desire. However, there are some Oldtimers who still wants to fulfill their own personal desire and ends up causing commotion, like Barometz.

On the other hand, human members of Outlaw who were duplicated to Xanadu apparently retain no memories of anything related to the Crimson Realm, resulting them falling into chaos. Later on, Outlaw is reorganized by Flame Haze from the old world and the Orderists (秩序派, Chitsujo-ha), a group of Crimson Lords who once lost their contractors and now materializes themselves without using human shells.

Some individuals who believe that Humans and Crimson Denizens could coexist in this world continues their long journey to accomplish it; these people include Yūji Sakai and Doog, the survived member of Révolution.
