Kunitsu (国津神, Kunitsukami)?, also known as Nation Ruler, is a demon race that exclusively includes the deities from Japanese mythology. Its relationship with the Amatsu resembles the rivalries between Deity–Tyrant or Divine–Fallen races. Kunitsukami represent the deities of the earth, which were conquered by the Amatsu, gods from the heavens. They are Light-Chaos and belong to the Guardians species.
Devil Summoner: Raidou Kuzunoha vs. King Abaddon[]
The curse of the Kunitsu plays a role during several Case Files, with the Summoner Tsunatsugu requesting Raidou deal with it as his family had been inflicted with the curse for generations. The curse first summons a pack of Oni in the Case File The Curse Reborn, who plan on turning the capital into a new hell. Though defeated, the curse is not lifted. Tsunatsugu later gives a quest concerning a rumor about how a Prince of Darkness will enter the world through the Catholic Church in the Case File The Prince of Darkness, whose goal is to create a land of the dead.
The final quest given by Tsunatsugu is Return of the Dead, where it's revealed that Okuninushi had been possessed by the hatred of the Kunitsu and that the curse was behind Mot's attempt to enter the world. Seeking to get revenge on the Amatsu who allied with the Hebraic Gods to seal away and imprison them, the anger of the Kunitsu seeks to make a paradise of the undead. Though defeated and freed of the curse, Okuninushi warns that the grudge will never dissipate and asks Raidou to free other Kunitsu deities possessed by it. Tsunatsugu's curse by the Kunitsu is also sealed away by Okuninushi for 100 years as gratitude for his freedom.
