Layer Weight - Sen is a weight built into the layer. It features six sides that enhance the stability and centrifugal force with the weight concentrated at the outer edges. Sen is similar to Goku in shape with Sen being significantly lighter than Goku. This is due to Sen being mostly holly in the center. Sen has very little use being outclassed by Zan in weight though it possesses superior stamina and Goku in terms of weight and stamina. Sen should only be used when Zan and Goku are not available.
