Камен Райдер Хибики: Герои чистой силы звука

is a Japanese tokusatsu superhero television series, serving as the fifteenth installment in the popular Kamen Rider Series of tokusatsu programs. It is a joint collaboration between Ishimori Productions and Toei. Kamen Rider Hibiki first aired on January 30, 2005 and aired its final episode on January 22, 2006. It aired as a part of TV Asahi's Super Hero Time along with Mahō Sentai Magiranger. This series is noted for introducing new themes and styles yet unseen in other shows. The catchphrase for the series is: "To us, there are heroes." (ぼくたちには、ヒーローがいる). Kamen Rider Hibiki is the first Kamen Rider Series to be broadcast in a high definition format.

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 rise of Makamou numbers proves to be a prelude to an upcoming calamity.

The regular antagonists of the series; the Makamou (魔化魍) are an assortment of monstrous creatures that usually dwell in the rural areas and consume human beings as food. Chimerical in appearance with their size and shape depending on the environment they are born in, and serving as the basis of the yōkai myths, the Makamo are a naturally created phenomena though some have been modified by the Man and Woman to be stronger and unpredictable. But the Makamou can destabilize and explode when exposed to pure sound produced by the Oni's attacks. In the final arc, a chain of events called the Orochi Phenomenon (オロチ現象) occurs. Marked by the appearance of Kodama's Forest, every known Makamou appears at the same time, increasing in massive numbers to the point where not even the Man and Woman can control them. By the climax, the Makamou start to dissolve into a purple miasma and killing by the hundreds. Hibiki eventually stopped Orochi by performing the sealing ritual, dealing with a massive army of Makamou bent on stopping him from ending their era before it could begin. In the end, the Orochi was halted and Makamou numbers dwindled back to normal.

The Giant Type Makamou are most common type of Makamou, essentially daikaiju with heights that vary from 22 ft. to 75 ft. Makamou that fall under this listing include Tsuchigumo (ツチグモ) and Bakegani (バケガニ).

The Summer Type Makamou are human sized Makamou that normally appear during the summer, apparently starting the Japanese legend of ghosts and yōkai appearing on Earth during the summer. While the Summer Type Makamou lack in size, they make it up in their ability to replicate themselves in large numbers and when one is destroyed they can easily be replaced. The key to destroying them is to destroy the original so no more replicates can be created. The Ongekida finishers are the most efficient way of destroying them.

The Experimental Type Makamou are Makamou developed by the Man and Woman to suppress the other two types, modified to be resistant to Oni attacks after the Man and Woman analyzed the Armed Saber.

The Kodama (spirit) (Kodama) is a tree like Makamou whose appearance marks the beginning of an Orochi event, able to traps its victims within a forest it spawns. Todoroki was dispatched to investigate, only to be ambushed by a wooden puppet Kodama created. The puppet managed to overpower Armed Hibiki and drive the Oni out of its forest. The Kodama later reappeared, trapping Ibuki and Kasumi, whom the monster intended to eat. While Ibuki and Todoroki battle the medium, Asumu and Kyosuke find Kodama and manage to free Kasumi from it, the medium feeling its master's pain before being quickly destroyed by Ibuki while Kodama is destroyed by Armed Hibiki.
