The Femushinmu are the native beings of this planet. After the Trial of Helheim, their Woman of the Beginning, the Femushinmu Queen chose her king Rosyuo as their kind's Man of the Beginning. Rosyuo began converting his people into the forms that can adapt to the forest, Inves. The Femushinmu later attempted to replicate the powers of the Golden Fruit, resulting in Kougane. However, Kougane tempted the Femushinmu to obtain the "Golden Fruit" and its power causing them to turn on each other. The Femushinmu eventually massacred each other, leaving the strongest behind. Shamubishe risked his life and sealed himself and Kougane. By this point, the Femushinmu were already close to extinction.
