In the distant past, there was a prophecy of a catastrophic event that would occur in the nine provinces of Kyushu. It was believed that falling comets would deplete the spiritual energy of the heavens and the lands, leading to a chaotic era. However, to everyone's surprise, the comets passed by without any incident. Meanwhile, in a secluded village in the Sokei region, a boy named Ouriku was born, seemingly affected by the cosmic phenomenon. Twelve years later, as the prophecy fades from memory, one of the most prominent sects, the Reikenzan clan, decides to hold an examination to identify the most deserving individuals to become sages. Ouriku and his loyal servant, Ouchou, venture towards the exam site in hopes of being selected. However, they are oblivious to the fact that the organizer of the trials, Oubu, has a notorious reputation for being reckless and unpredictable, despite her refined demeanor. The anime Reikenzan: Hoshikuzu-tachi no Utage chronicles Ouriku's journey as he endures the grueling trials in his quest to become a mighty sage.
