World of Hibiki

The World of Hibiki (響鬼の世界) is the version of reality where Kamen Rider Hibiki takes place. In this world, humans train to become Oni within one of three rival schools of sound-based martial arts called Ongekidō (音撃道), all based on different interpretations of the writings of the Grand Master (大師匠), the creator of Ongekidō. The masters and students of the Ongekidō styles wear traditional Japanese clothing, Tsukasa donning such attire while in the A.R. World and given the ability to use the Ongekibou. Daiki's treasures in this world are the three scrolls containing the secrets of the three schools of Ongekidō. The backdrop used to enter this world depicts a forest with a taiko drum in the foreground. Nearly all of the original cast of Hibiki returns to reprise their roles, with only Shigeki Hosokawa (the original Hibiki) and Rakuto Tochihara (the original Asumu) absent. The episodes also show calligraphic representations of the Kamen Riders' names: "Tsukasa Kadoya" (門矢士), "Photo" (写), "passing through" (通), "Decade" (ディケイド), "Sea Cucumber" (海鼠), and Pink (桃色) for Decade; "Kuuga" (空我) for Kuuga; "Peach" (桃) for Den-O; and "Thief" (盗) and "Diend" (ディエンド) for Diend.
