Like with the other Armored Riders, Kamen Rider Kurokage's forms are called Arms (アームズ Āmuzu). His Sengoku Driver plays Japanese horagai music and announces "Soiya" (ソイヤ "Soiya") before every transformation, while his personal Lockseeds are styled with a mix of Japanese words and English words. By pressing the Sengoku Driver's Cutting Blade down on the Lockseed after transforming from one to three times, Kurokage can activate one of three finishing moves based on his current Arms form: Squash (スカッシュ Sukasshu), Au Lait (オーレ Ōre), or Sparking (スパーキング Supākingu).
