Asumu (Decade)

is Hibiki's child apprentice, wanting to become a full-fledged Oni just like his master Hibiki in the Ongekido Taiko style, which is Hibiki's branch. He became the next after his master turned into Gyuki.
==History==
===Kamen Rider Decade===
====World of Hibiki====
Asumu is the only student of the Ongekido Taiko Drum Style. Before inheriting Hibiki's powers, Asumu was able to assume a form called .
As a result of his master losing the ability to control his Oni powers and fight the Makamou within himself, Asumu later inherits the power to become Kamen Rider Hibiki, and uses his new abilities to work together with Akira (Kamen Rider Amaki) and Todoroki (Kamen Rider Todoroki) to ally their schools. 
====World of the Rider War====
Asumu later appears in the World of the Rider War after his reality is absorbed into it, being the only survivor of the attack of the Fangires led by Kamen Rider Saga thanks to Daiki. After defeating Super Apollogeist, the convergence of worlds is not stopped and both the World of Hibiki and Asumu disappear. 
===MOVIE War 2010===
Following Tsukasa's death, Asumu, is revived and reunited with his friends, sharing the same fortunate fate as the other worlds' Riders. He later helps revive Decade and then appears along with Wataru to aid Decade in the final battle against Super Shocker to repay Decade for saving his world, turning into Kamen Rider Armed Hibiki thanks to Decade's K-Touch.
===Later appearances===
MOVIE War 2010 currently remains the last appearance of Asumu. The Hibiki that appears in OOO, Den-O, All Riders: Let's Go Kamen Riders, Kamen Rider × Super Sentai: Super Hero Taisen and most of further crossovers is the original Kamen Rider Hibiki, also known as simply Hibiki.
==Forms==
Just like the other Kamen Rider Hibiki, this alternate incarnation simply needs to tap his Onkaku against a solid surface, the vibrations from the fork causing his body to be engulfed in a fiery flaming purple aura and assume his Oni form. Using his Ongekiko Kaentsuzumi buckle in conjunction with his Ongekibou Rekka drumsticks, Hibiki can execute his Ongekida attacks.
==Equipment==
===Devices===
*Henshin Onsa Onkaku: A fork-like transformation device.
*Ongekiko Kaentsuzumi: A device that attaches on his belt for uses of finisher attacks.
**Ongekiko Bakuretsu Kaentsuzumi: An upgrade version of the buckle.
*Disk Animals: Hibiki's disk-like support robots.
===Weapons===
*Ongekibou Rekka: Personal weapons
*Ongekizofukuken Armed Saber: Armed Hibiki's primary weapon.
==Notes==
*Asumu is based from Hibiki character Asumu Adachi, and with Hibiki, is part of the characters from the World of Hibiki to not be reprised by their original counterparts' actors, Rakuto Tochihara for Asumu, and Shigeki Hosokawa for Hibiki.
*Asumu is with Wataru, part of the only A.R. World Riders whose civilian identity are children. This might be in reference to their Hyper Battle Videos, where children are implied to become Riders (Kamen Rider Hibiki Hyper Battle DVD: Asumu, Transform! You can be an Oni, too!! and Kamen Rider Kiva Adventure Battle DVD: You Can Also be Kiva).
**Also, both Asumu and Wataru grow to the size of adults when transformed, however their voice remain the same as their civilian one.
*Transformed Asumu's form appears physically similar to Transformed Kyosuke, albeit only lacking a proper Oni mask.
*He wears a deep violet kimono with crimson accents, the design of which is similar to the outfit of his namesake from the Sengoku Period in Kamen Rider Hibiki and The 7 Senki: The Movie, but with the color scheme of the robes of the Hibiki of that era.
*In his later appearance, Asumu yelled Henshin when changing into Hibiki, a practice never before used by any Rider related to Hibiki.
