Koshi Castle

Koshi Castle (古志城) is a stage exclusive to the Warriors Orochi series. It serves as the final stage for all story scenarios in Warriors Orochi. Though Koshi is a district in Japan, the castle is fictional as there are no historical records of it.

Role in Games
The castle is implied to be Orochi's base of operations as the armies fight here for a decisive battle against the snake demon. Koshi Castle is a hidden fortress situated in the bleak wasteland of a semi-active volcano caldera. Surrounded by four cannon bases and garrisons at each corner of the map, the castle is well defended. The gates are surrounded by two drawbridges over a moat of molten lava, which block intruders from entering. When the defenses are ruined, Lu Bu will often serve as the final guardian before reaching the inner keep.

In Warriors Orochi 2, the place is not visited as frequently. In Shu's story mode, Kiyomori uses this location to conduct a ceremony to resurrect his lord.
