Kamen Rider Hibiki's main focus is the story of the teacher and apprentice-like relationship between Adachi Asumu and the title character. Adachi Asumu is a young boy who is unsure of his own skill and worth and is at a crossroads in his life as he transitions to high school. As the series progresses, he learns what it is to be a man, more confident in his own power. The secondary focus of the series is the age old battle of the Kamen Riders (referred to as Oni in this program) and the Makamou, demons that can only be defeated using "pure sound". The series follows the training and changes of the four main Oni, Hibiki, Ibuki, Todoroki and Zanki.
