- "Sanat Kumara. His name means "eternal youth" in Sanskrit. He is one of the four sages created by the god Brahma. In one account, he descended to earth from Venus millions of years ago to speed the evolution of man. In recent years he has been viewed as being the same as Kurama Tengu and Lucifer."

In "The Eternal Youth" DLC, Flynn is transported to Infernal Tokyo by the White in order to drive him to despair. Flynn arrives in front of Akira, who is running for his life from Sanat's overwhelming power. He is eventually cornered and threatened with death by his demonoid "subjects" if he does not stop Sanat. Akira uses Flynn's presence to his advantage again and begs Flynn to fight in his stead at the Yamato Perpetual Reactor Room in Camp Ichigaya.
Flynn is at first unable to perceive the entity; even Burroughs is unable to correctly scan Sanat, saying she only gets error messages, and like the Ancient of Days, she comments it's possible he isn't made of materials native to Infernal Tokyo. Sanat is made visible by an energy pulse, and taunts Flynn about being a "little creature, of lower dimensions." He explains that he was the one who planted the seeds of chaos on the planet eons ago, and is overwhelmed with joy at how it resulted in creatures that are able to fight him and are no longer mere apes after ages of evolving. As the fight starts, he tells Flynn, who he calls a human, full of potential: "Show me how far this 5th humanity has grown! Show me your worth...!" and says that he will personally draw out the power within his opponent.
As the second part of the fight initiates, Sanat will mention he will take Flynn to the "true war", asking whether Flynn understands what he's talking about. Regardless of the answer, Sanat will clarify he meant the war against "the dispensation of the universe", a phrase the Ancient of Days often repeats at the start of the fight against him and what it calls its mission.
As Sanat falls, it joyfully commends Flynn for showing him such unrestrained power, and orders him, as the "seed of chaos", to further "ripen" and lead the world into further chaos, saying they will meet again when the time of the next harvest comes.
Sanat will only begin using Gaea Rage if his weakness to Gun is exploited.
