Dove, Fly up to Heaven!

STORY

Abiru, the master of the Blood Pond on Mount Kurogatake, and the Tengu of Mount Kurohime are about to settle their long-standing feud in a duel at Ryūga Fuchi. Just then, Princess Tatsuta, the guardian spirit of Ryūga Fuchi, appears before them to stop the duel. But, despite her plea, the two mountain lords refuse to end their rivalry. As their battle continues year after year, violent storms ravage the surrounding region, crops fail, and the villagers are driven to the brink of starvation.
On the other hand, a villager named Matahachi, who is searching for his missing wife Okame and their two children, comes across a giant serpent trapped beneath a pile of rocks and rescues it. The serpent is, in fact, Tatsuta, who has been driven from Ryūga Fuchi. To repay Matahachi's kindness, she takes the place of the missing Okame and goes to live with his family, raising his two children as her own.
Under Tatsuta's care, the children, Takamaru and Hatomaru, grow into brave and powerful young boys. One day, however, they accidentally discover their foster mother's true identity. Unable to remain with them any longer, Tatsuta leaves the family. Before departing, she entrusts the brothers with a magical comb, telling them that if they snap off one of its teeth and cast it away, she will come to them.
Thus, the grand adventure of the two brothers with the mysterious comb that binds them to Tatsuta finally starts.
