Kugai Kudo

Kugai Kudo (狗道 供界) is a former researcher in Yggdrasill Corporation who transforms into Kamen Rider Savior (仮面ライダーセイヴァー). His only appearance was in Kamen Rider Gaim Gaiden: Kamen Rider Duke.

History
He was a former colleague of Ryoma Sengoku until his alleged death in a Lockseed-creation accident. He returns years later as part of the Black Linden organization that targeted Yggdrasill.

Arms
Like his fellow Lockseed-using Armored Riders, Kamen Rider Savior's forms are called Arms (アームズ). His Sengoku Driver plays Japanese horagai music and announces "Soiya" (ソイヤ) 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, Savior can activate one of three finishing moves based on his current Arms form: Squash (スカッシュ), Au Lait (オーレ), or Sparking (スパーキング).
