|This article is about a former rider in Kamen Rider Decade.|
Hibiki (ヒビキ) was Hitoshi Hidaka aka original Hibiki's incarnation from Kamen Rider Decade. He is the master of the taiko-based Ongekido Hibiki Style (ヒビキ流, Hibiki Ryū) and thus Asumu's teacher, referring to him as Shounen (少年, Shōnen).
Kamen Rider Decade
World of Hibiki
He lost his righteous heart through his desire to become stronger, Hibiki is consumed by his Oni power and starts his metamorphosis into the legendary half-Ox Makamou and half-Oni, Gyuki. As a result, Hibiki adopts a lazy and rude attitude to most people, wears modern clothing, and even attempts to drive Asumu away in an attempt to retire from being an Oni. It is only when Kuuga is about to get killed by a Tengu Makamou that Hibiki decides to assume his Oni form and transforms into Gyuki as a result, wounding Ibuki and Zanki before being driven away by their pupils. Knowing that he will no longer be able to assume his human or Oni form again should he transform into Gyuki, he gives up his Transformation Tuning Fork Onkaku to Daiki Kaito to give to Asumu, who becomes the new Hibiki and slays his former master as his final request. After he became Gyuki completely, he attack Decade and Hibiki mercilessly before Hibiki attack him with Mouka Dotou form. In an imaginary scene between Asumu and Hibiki, Hibiki entrusts Asumu with Hibiki Henshin Onsa (which means entrusting the soul and also the license) and dies.
Hibiki is seen assuming his default Oni form before becoming Gyuki. It is unknown if he ever accessed the Hibiki Kurenai (響鬼 紅, Hibiki Kurenai) or Armed Hibiki (装甲響鬼, Āmudo Hibiki) forms during his career as an Oni as did his original counterpart.
- Height: 7 shaku 3 sun (approx. 221.2 cm, one say 222 cm)
- Weight: 41 kan (approx. 153.8 kg., one say 156 kg)
- 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)
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.
Because his desire to kill all Makamou is too strong, when he assumes his Oni form, Hibiki involuntarily becomes the legendary Makamou Gyuki (牛鬼, lit. Ox Demon), attacking any and all who get in his way. Later in Episode 19, Hibiki became Gyuki completely without becoming an Oni first. He is later finished by Asumu after Asumu decided to became the new Hibiki and defeat him using Mouka Dotou form, thus killing Hibiki.
- Henshin Onsa - Onkaku
- Ongekiko - Kaentsuzumi
- Disk Animals: Hibiki's disc-like support monsters. It was used as shuriken while in human form. He abandoned it once Gyuki's power took over his body.
- Ongeki Da: Kaen Renda no Kata (音撃打・火炎連打の型 Sound Attack Stroke: the Flame Barrage Style) While his Kaentsuzumi is attached to a large Makamou, Hibiki beats it 30 times rapidly with his Rekka. The Sound of Purification resonates through its body, causing it to explode. This was used by Hibiki to destroy a Tengu which had attacked him and Asumu.
