The omni-directional mobility gear (立体機動装置 Rittai kidō sōchi?), is a set of equipment developed by humans that allows great mobility for cleaning the Titan Junior High School's Walls. The equipment allows the user to maneuver in a 3D space as opposed to a 2D one. The equipment itself takes the form of a body harness that encompasses much of the body below the neck.
Although the equipment can grant a skilled user tremendous mobility, it is a demanding art that requires both strength and skill, both of which must be honed through constant practice.
Some tools involved in the apparatus include:
- Hand grips
- Piston-shot grapple-hooks
- Gas-powered mechanism
The simplest move possible with the ODM gear is simply aiming and firing the grapple hooks at an object and then activating the gas mechanism to reel oneself toward the said object. They can then disconnect the hook and continue moving forward.
