The Iron Sand Gathering Assault is a technique which gathers a great volume of Iron Sand and compresses it into a high-density shape.


This technique greatly increases the hardness of the Iron Sand, creating a gigantic steel-like weapon in an instant. The weight and size of these shapes are so great, they can easily shatter bedrock and break through most defences with a single hit.

Because the weapon is made out of Iron Sand, the shape can be whatever the user wants, and can even be changed during the fight. This allows the user to create the best weapon for the fight, by taking into account the opponent's abilities and the surrounding environment. Since the Iron Sand generates a strong magnetic field, the opponent cannot use any metal weapons or tools.

Edge (, Ei)[5]
This large, triangular shaped weapon allows the user to penetrate through defences as strong as rock. It can be spun to pick it up even more power, giving it a drill-like appearance. It can also be shaped into a thinner, but longer version of it to increase its range.
Iron Sand Five Sun Nail.png Five Sun Nails (五寸釘, Gosunkugi)[6] Besides being capable of penetrating through someone's body, these long spikes can be used to attack multiple targets. The user can also hover them over their target to launch them down at any time with incredible speed.

Hammer (, Tsuchi)[6]
This giant block-like weapon can be used to crush its target with devastating power as a giant block that is used to crush the target.
