Similar to a machine, Ether Gear utilizes the Ether that flows from the user's body and rearranges it by turning it into power, making the user into a "mechanical wizard" of sorts. This gives its users the ability to manipulate certain elements such as gravity and wind, reconfigure machines, create swords made of Ether that can be used in combat, or change the material of objects. However, Ether Gear has the peculiar weakness of being completely unusable when its user cannot use their hands, such as if their wrists are tied, and if the user is hit by an Electromagnetic Pulse. However, it can be remedied by training to overcome the Ether deficit caused by physical restraints, and that being able to use Ether Gear even when bound takes practice.
Ether Gear typically takes multiple years to master, though some can use it after only one month. After their initial manifestation, an Ether Gear can awaken and reveal more abilities.
Ether Gear powers can be extracted by means of a special device and made into weapons such as the Petrification Ray or vehicle-mounted weapons.
Ether Gear is mentioned to have been a power from the Dark Ages.
