The Transformation Belt Garren Buckle (変身ベルト ギャレンバックル Henshin Beruto Gyaren Bakkuru) is the transformation device that Sakuya Tachibana uses to become Kamen Rider Garren. It was designed for specific compatibility with the ♦A: "Change Stag" Rouse Card and harnesses the DNA of the Stag Undead. This model utilizes the "Turn Up" mechanism (similar to the Blay Buckle) to produce a stationary transformation screen, which initiates the fusion of Undead DNA with a human to produce the Kamen Rider transformation. Coincidentally, the transformation screen itself can act as a deflective wall against assaults.
- During its usage in Super Hero Taisen GP: Kamen Rider 3, the transformation screen produced by the Garren Buckle moves towards the user much like the screen produced by the Leangle Buckle. The reason for this is unknown.
