As Black Zetsu siphons Naruto and Sasuke of their chakra, he reveals Kaguya's story to them. Many ages ago in what would become the Land of So, a tree grew from a meteorite that crashed onto the world. Years later, the people of So see a glowing object landing off in the distance. The young So emperor Tenji sends his soldiers and they return with a mysterious woman who, after wiping away the memories of those present, introduces herself as Kaguya and claims herself as protector of the God Tree while requesting an attendant. Soon after, falling in love with Kaguya as they both desire peace in the world, Tenji finds himself at odds with representatives from the Land of Ka who seek to expand their territory by any means from false documents to war. Even learning that Ka is starting to stir conflict, Tenji decrees to his subjects they are not to attack Ka on any reason. But when men from Ka attempt to abduct Kaguya, she effortlessly slaughters them and a Ka representative named Suzaku later exposes her actions during peace negotiation. This forces Tenji, unaware that she was pregnant with their twin sons, to order Kaguya's death to keep the peace. Betrayed, Kaguya makes her way to the God Tree while her attendant sacrificed herself to protect her from arrow fire. Kaguya eats the God Tree's fruit and uses her newly gained powers to invoke the Infinite Tsukuyomi, binding Tenji and those caught in its light within the God Tree's roots.
