Hibiki Riders

This article is about a set of riders in Kamen Rider Hibiki.

Sound Attack Warrior (音撃戦士, Ongeki Senshi), also called "Oni" (鬼, "Oni" lit."Demon") most of the time, which is also including into each Oni's alias as a suffix of sorts. In-universe, they are mostly unknown outside their organization in the present day, but were oftentimes feared in the past for their power and shunned for "sacrificing of their humanity" by becoming Oni. Unlike other riders, they did not wear a mask or any kind of suit, but its true demon form.

Despite the title of "Oni", they are not to be confused with the "Oni Brothers" Mimihiko and Kuchihiko, the antagonists of Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship.

Overview

A warrior who has trained the mind and body by training and has acquired the ability to transform into a battle form called "Oni". It is divided into several groups depending on the type of their Ongeki Weapon used. In the TV series, there are 3 types: Drum Oni (鼓の鬼, Tsudzumi no Oni), Tube Oni (管の鬼, Kan no Oni), and String Oni (弦の鬼, Gen no Oni), and each has a different strengths, weaknesses and strategy.

They have a body with a glossy appearance and decorations based on the type of Ongeki Weapon were used (around the chest, wrist and ankle). Their face has no eyes and nose, and decorated with colored face lines, different on each Oni. The horns grow on the top of the head, and on the forehead, the same Oni's face emblem appears as on the transformation devices called Oni Face (鬼面, Kimen).

If an Oni fights relying on his or her anger, the Oni Face will grow over the face. When an Oni becomes evil, Takeshi headquarters will decide if they should be eliminated. If they decide to eliminate the Oni, they send someone from the head family to carry out the task.

Oni follow a one-master-one-apprentice tradition. Upon the retirement of their master, an apprentice will inherit the responsibilities as well as all equipment from his predecessor. He will often inherit the master's title too, but there are exceptions.

The Oni of today are working under the organization Takeshi who assist their activities. The Kanto branch, which appears in the series, has 11 Oni, who work in shifts. In addition, those who became independent as Oni are all given their Oni name as a codename, and will be known by that name instead of their real names regardless of whether they are inside or outside the society.

Transformation

An Oni makes a Oni Face appear on the forehead by bathing with a special sound wave emitted from the transformation device, and transforms into an Oni who controls the power of the attribute. At that time, the clothes worn were destroyed, and after transformation they would be naked if they were not trained enough or extreme fatigue due to lack of energy after a fight. In addition, because transformation consumes a great deal of mental power and energy, they cannot transform unless trained to a level that can withstand it. Inexperienced Oni's apprentice cannot restore clothes, happens to Akira Amami. The transformation devices identified in the TV series, they are 3 types: Onsa, Onibue, and Kigen.

However, when Todoroki was forced to cancel the transformation in Kamen Rider Zi-O, his clothes remained intact.
