2. The setting of the transformer
Decade's transformation belt. The ability to use the Dimensional Transformation Liberator will liberate the energy of the Knight Card sealed in the 2nd dimension (plane) into the 3rd dimension (stereoscopic). The interior contains a secret stone known as the "Trickster" that serves the function of creation. In addition, the belt has the mysterious symbols of the six elements of 'earth, water, fire, wind, light and darkness' from left to right, which are the root causes of the formation of the "Decade drive". The drive has a parallel world of Kamen Rider's Coat of Arms. It is The Testament that inherits the power of the knights in various parallel worlds.
Decade's new transformation belt. Evolved from the "Decade Drive". The main body of the belt has changed from white to magenta, the Kamen Rider's coat of arms on it has been updated to Build, the related deck has been updated to Zi-O, and the sound effects of KamenRide and FormRide's Transformation Sound Effects original version of the Knight are more complete than in the old version. The Divine Ore of the armor material has been coated with ultra-fine particles, which greatly improves durability compared to the old model.
