Iron Sand Gathering Assault: Hammer

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.


Two shapes have been shown:

  • The Giant Spear (巨大槍, Kyodaisō): by forming the Iron Sand into a triangular, spindle-shaped object (much like a pyramid) and tapering it into a sharp point at one end, the user creates a giant spear, which can extend rapidly to pierce an opponent or spin like a giant top.
  • The Giant Hammer (巨大鉄槌, Kyodai Tettsui): by forming the Iron Sand into a large rectangular shape, the area of contact is increased greatly, creating a giant, hard-to-evade hammer.
