cost of his life. Kagachi then defeats Kushi, learning as he dies that the Night Devil is a Daemon filled with hatred that wants to end the world. Lobelia further reveals that the true sovereign was key to preserving the world, and a terrible force has been preparing itself since she ended the bloodline. Kagachi finds the Night Devil: Kagachi then learns that the Night Devil is a fragment of Kagachi from a previous life when Kagachi was named Soju, the banished brother of the true sovereign. After defeating the Night Devil and absorbing him, Kagachi kills himself to quell his hatred. Linne, transforming into an adult form, prays for Kagachi to make a new future as a monster emerges from underground to destroy the world. Awakening as Soju in the past, Kagachi pieces together his history; raised by an assassin's guild, Soju acted as a precursor to the Watchers as he carried out the last wishes of lingering spirits. After one such mission, he was killed. Meeting Sara, he realises that "Linne" was her spirit. Sara explains that the sovereign must keep the Oni, a manifestation of the despair humans discard during reincarnation, from awakening; the monster seen awakening in Kagachi's last life was the Oni. They go to the First Pillar, an ancient magical landmark, and view murals of humans defeating the Oni and Sara's ancestress establishing Szaka, with the Oni sleeping under it. Journeying into the palace and entering the pool of despair at its heart, Kagachi experiences the hopes of those who fought the Oni in ancient times as he escapes; during this time he sees Szaka, called here the Wailing Land where the Oni sleeps. The Oni is revealed to have created the Cycle of Reincarnation to nourish itself with despair, heralded and nurtured by a human avatar called the Oni Priestess; with each awakening and defeat, the Oni destroyed a little more of the world, until only a portion of it remains. Its next awakening will destroy the world, also leading to the Oni's demise without humans to feed it. Kagachi confronts Sara, the current Oni Priestess, and she asks him to decide the world's fate. Kagachi can choose to accept the Oni's awakening and the world's end, or fight Sara. Defeating Sara, he then destroys the awakened Oni. Kagachi then chooses to either kill himself or watch over the world from the Beyond.
