|This article is about a/an novel-exclusive Rider in Kamen Rider Hibiki.|
|"You kill me... But nothing ends...History repeats... Devil will attracted by the power like this, those who try to consume the world will certainly appear... Someone will succeed my will!"|
|―Shokuki's last words.[src]|
In the climax arc of the novel, he turned into a crow-like Makamou named Incarnation Ninja-Demon Hybrid (化身忍者と鬼のハイブリッド Keshin Ninja to Oni no Haiburiddo).
Also known as Yo o Mushibamu Oni (世を蝕む鬼, lit. "The Devil Who Undermines the World"), he is treated as a Dark Rider, and attached to the title as a Kamen Rider, but the notation in the novel is "Shokuki". A hybrid of incarnation ninja and Oni, his motif is a crow.
Like Arashi, it transforms with the vibration of the sword, but Shokuki uses a Japanese sword. Then, his body is wrapped in a flame of jet black, and the transformation is completed after making a strange sound.
Kamen Rider Shokuki's body is covered with feathers like a crow, and the body is the body of the Oni itself, and there is a second Oni's face in his forehead.
- Ninpou: Kuroha no Mai (忍法 黒羽の舞 Ninpō Kuroha no Mai, lit. "Ninja Method: Black Feather Dance"): This attack is similar as Arashi's Feather Shuriken.
- Ongeki Satsu-hō: Kamaitachi (音撃殺法 かまいたち, lit. "Sound Attack Killing Law: Whirlwind's Cut"): Shokuki's Ongeki Finisher. The enemy is smashed up with the sound wave emitted from his sword.
Because Shokuki is the hybrid of Oni (or Makamou) and incarnation ninjas, it is also possible to be defeated only by combining the Oni's Ongeki and the power of incarnation ninjas.
