Masked Rider Hibiki / 响鬼
The Kamen Riders, known as Oni, battle man eating beasts called Makamou with “pure sound”.
One of the Oni, a man named Hibiki ends up having a teacher and apprentice-like relationship with Asumu Adachi.
A young boy unsure of himself and is at a crossroads in his life as he transitions to high school,
Asumu learns to be an adult through watching Hibiki and the other Oni as they all train together to hone their skills in fighting the Makamou and the homunculi aiding them.
However, the sudden raise of Makamou numbers proves to be a prelude to an upcoming calamity.
自古以來，在日本有很多為了保護人類，
這樣做是為了對抗魔化魍。漸漸的，
馬上就要高中應考的少年安達明日夢，在往屋久島的船上，
到達屋久島的明日夢，在森林裏，被巨大的土蜘蛛襲擊。這時，
這正是「響鬼」與明日夢相遇的一刻。
