Drafting:
In this season, the Kamen Riders, who are recognized as Oni, engage in combat against man-eating beasts known as Makamou. To combat these creatures, the Oni utilize pure sound. The narrative follows Hibiki, an Oni, who maintains a relationship with Asumu Adachi that resembles that of a teacher and an apprentice. Asumu Adachi is a young boy navigating a period of personal uncertainty and a life crossroads as he transitions into high school. Through observing Hibiki and the other Oni as they engage in collective training to improve their combat skills, Asumu learns the processes of becoming an adult. This training involves working alongside homunculi to prepare for battles against the Makamou. The stability of this training period is threatened when the population of Makamou begins to rise suddenly. This increase in the number of beasts serves as a prelude to an impending calamity that threatens the characters. The season focuses on the development of Asumu Adachi and the ongoing struggle of the Oni to defend against the growing threat posed by the Makamou.
