This techniques basic form is a giant sphere with 3 times the high density making it extremely heavy that is sent crashing down on opponent with its weight to flatten them. Its advanced form simply changes the sphere to a large rectangular block covering more ground. The Fall Down also has a trap version as 5 diamond pillars around the opponent to which user creates bolts to Seal his opponent inside.
