Guardian of the Dream (夢の守り人, Yume no Moribito) is the third novel in the Moribito series written by Nahoko Uehashi.
People start becoming trapped in their dreams. Tanda's niece, Chagum, and the First Queen all dream of a flower with ties to Torogai's past. Only a man with a supernatural singing voice can save them.
Balsa rescues a young-looking man (she guesses about 20) named Yuguno, who is on the run from slavers. Yuguno is actually 52, but he has been blessed with long-lasting youth by a flower spirit; when he sings, those who hear the song fall into a dream, and the flower spirit feeds on their dreams. Those who do not wish to wake up, however, can become trapped, and if the flower drops its seeds before they wake, they will die.
Tanda's niece, Kaya, has been betrothed to a man she does not love. She falls into a deep sleep and will not wake (much like the "Flower Wine for Tanda" episode of the anime, where the sleeper is Saya), so Tanda does a soul call to see if he can guide her back. Instead, he falls victim to the flower, which tricks him and posesses his body, turning him into a monkey-like monster while his soul remains in the dream world.
Meanwhile, both Chagum and the First Empress (Sagum's mother) have also become trapped in the dream world, where Chagum dreams of the time he spent in the Hunting Cave with Balsa and Tanda. Shuga, who has been meeting in secret with Torogai above Toya and Saya's shop, looks to her expertise to rescue the prince. Tanda, in the dream world, tells Chagum how to rescue him from the demon that has stolen his body.
Shuga borrows three of the Hunters (Jin, Zen, and Yun) and takes them to meet Torogai and Balsa to save Tanda from the demon. While Balsa and the Hunters fight the demon, Torogai ventures into the dream world to wake the dreamers and save Tanda. Torogai is able to convince Kaya to wake by explaining how she, too, was in a loveless marriage, and that she had three children who all died in infancy. After that, Torogai fled her marriage and became a reclusive shaman.
Ultimately Balsa manages to defeat the demon and Torogai succeeds in freeing those trapped in the dream world. Tanda returns to his body and must then recover from his many injuries, while Balsa sticks around to take care of him.
