The world of the Mazes does not significantly change with variations in weather or sunlight in the few areas where the outside can be seen. Therefore, there are no seasons to speak of.<br/>
The term "season" refers to largely symbolic groups of months - usually trimesters. Their signficance varies depending on culture. Angelic faith recognizes four seasons of three months each, based on each one of their deities:* The '''black season''' or '''season of the Black Tortoise'''* The '''blue season''' (sometimes '''azure season''') or '''season of the Azure Dragon'''* The '''red season''' (sometimes '''scarlet season''' or '''vermilion season'''), or '''season of the Vermilion Bird'''* The '''white season''' or '''season of the White Tiger''' Youkai culture re-uses Angelic faith season names, simply translating the Angelic season names and deity names into their language, as follows:* Black season: '''黒季節''' (''kurokisetsu'')* Black Tortoise: '''玄武''' (''Genbu'')* Therefore, Season of the Black Tortoise: '''玄武の季節''' (''Genbu no kisetsu'')
