>>36364504It's the warring states era from Japan history, where you had dozens of independant, highly militarized states all working against each other until one warlord (Oda Nobunaga) managed to go through the country and united all the clans under his banner through conquest, diplomacy, trickery.
It's pretty cool stuff.
Moriji is a Japan AU where the warring states period never really ended but the Sohei Monks gained enough military and political power to curb down inter-state warfare.
