The Sousui formerly lived in Hakuma as the King. His castle was located extremely close to Hakuma's center, where the land's god was sleeping. The castle's other occupants were his wife Suigetsu, various servants, potential puppet soldiers, and Majinaishi (the future Shinyuuchi Hunters were made up of the latter two). Without warning one day, tired of enduring his younger brother's betrayals, the King left abruptly, taking only his future body, Suigetsu, Haruka, Zero, and Sango with him. Since that time, the castle had been inhabited by the Shinyuuchi Hunters, until the Sousui returned to reclaim control of it and all those within.
