Asumu

For the original or past version, see Asumu Adachi and Asumu (Sengoku Period).

**Asumu** (アスム, ***Asumu***) is Hibiki's child apprentice, wanting to become a full-fledged Oni just like his master Hibiki in the taiko drum-based Hibiki Style of Ongekido. He became the next **Kamen Rider Hibiki** (仮面ライダーヒビキ, *Kamen Raidā Hibiki*, "Masked Rider Hibiki") 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 similar to Transformed Kyosuke called Transformed Asumu.
As a result of his master losing the ability to control his Oni powers, Asumu later inherits the power to become Kamen Rider Hibiki, and uses his new abilities to work together with Akira and Todoroki to ally their schools. 「*Idle Hibiki*」 「*Ending Journey*」

#### 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 the World of Hibiki and Asumu disappears. Following Decade's death, he is revived and reunited with his friends. He later helps revive Decade and then appears along with Wataru to aid Decade in the final battle with Super Shocker to repay Decade for saving his world, turning into Armed Hibiki thanks to Decade's K-Touch. 「*Rider War: Prologue*」 「*Destroyer of Worlds*」

### 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* and *Kamen Rider × Super Sentai: Super Hero Taisen* is the original Hibiki, Hitoshi Hidaka.

## Forms

Just like the original Kamen Rider Hibiki, the current 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 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.

Notably, in one of his final appearances in the World of Rider War, he calls out 'Henshin' while transforming alongside Wataru, making him the only World of Hibiki rider to ever do so.

Before inheriting Hibiki's powers Asumu was able to assume a form similar to Transformed Kyosuke called **Transformed Asumu** (アスム変身態, *Asumu Henshintai*), only shorter, muscular, silver and has no "mask".

* Oni
* Armed
* Final Form Ride

**Hibiki**
 File:KRHi-Hibiki.png
* **Height:** 7 shaku 3 sun (approx. 221.2 cm, one say 222 cm)
* **Weight:** 41 kan (approx. 153.8 kg., one say 156 kg)

**Ability Parameters**:

* **Punching Power**: 5333 kan (approx. 20.0 t)
* **Lifting Power**: 600 man-power (6 t)
* **Kicking Power**: 10666 kan (approx. 40.0 t)
* **Maximum Jump Height**: 41 ken (approx. 74.5 m, one say 75 m)
* **Maximum Running Speed**: 1 chō per 3 sec (approx. 100 m per 2.8 sec, one say 3 sec)

In this form, Hibiki is a purple demon. This is his basic form and the easiest form for him to reach. To become this form, Hibiki simply needs to tap his tuning fork against a solid surface, the vibrations from the fork causing his body to be engulfed in a fiery purple aura. Hibiki also gains a second "oni face" which is a crest that forms on his forehead. Unlike most Kamen Riders, Hibiki does not wear a suit, rather his demon form is his true form.

**Armed Hibiki**

**Rider Statistics**

* **Rider Height**: 7 shaku 7 sun (approx. 233.3 cm, one say 233 cm)
* **Rider Weight**: 44.8 kan (168 kg)

**Ability Parameters**:

* **Punching Power**: 40 t
* **Lifting Power**: 800 man-power (8 t)
* **Kicking Power**: 80 t
* **Maximum Jump Height**: 100 m
* **Maximum Running Speed**: 100 m per 1 sec (one say 1 chō per 1 sec, approx. 100 m per 0.9 sec)

The final form Hibiki was able to reach is known as Hibiki Soukou or Armed Hibiki. To reach this form, Hibiki must use the Ongekizofukuken Armed Saber, the Ongekizofukuken Armed Saber also serves as a weapon in this form. When initiating the call Hibiki automatically assumes Kurenai Form. Hibiki calls upon the power of the Disc Animals to fuse with him, each becoming armored for his form. Finally, his oni face is covered with a samurai like shield, his horns expand, and the little oni face on his forhead is covered with the character for Armed, 甲. Though his transformation was unlocked through Tsukasa's K-Touch. Hibiki is able to destroy most lower level Makamou with little to no effort in this form.

Armed Hibiki is also able to execute a fiery Rider Punch; shown on Movie War 2010.

This form is exclusive to *W & Decade: Movie War 2010*.

*"Final Form Ride: H-H-Hibiki!"*
―Transformation announcement[src]
Decade's Final Form Ride allows Hibiki to change into **Hibiki Akanetaka** (ヒビキアカネタカ (茜鷹), ***Hibiki Akanetaka*** lit. "Hibiki Madder Hawk"), then when Decade activates the Hibiki Final Attack Ride Card, Hibiki Akanetaka transforms into the **Hibiki Ongekiko** (ヒビキオンゲキコ (音撃鼓), ***Hibiki Ongekiko***) to deliver the final blow.

## Notes

* Asumu is based from *Hibiki* character Asumu Adachi, and one of two A.R. World characters from the World of Hibiki to not be reprised by his original actor.
* Similar to Wataru, Asumu grows to the size of an adult when transformed into his Rider Form, however his voice remains the same.
* Transformed Asumu's form appears physically similar to Transformed Kyosuke's Oni form, albeit only lacking a mask.
* He wears a deep violet kimono with crimson accents, the design of which is similar to the outfit of his namesake from the Warring States era in Kamen Rider Hibiki & The Seven Senki, but with the color scheme of the robes of the Hibiki of that era.
* Asumu's last name hasn't been revealed by Toei.
* In his later appearance, Asumu yelled Henshin when changing into Hibiki, a practice never before used by any Rider related to *Hibiki*.
