ODM

Is short for omi direct manuever gear but it's also called 3D manuever gear. A gear mostly used by the eldian army on paradise. It is a really modern invention wich uses two grapling hooks and a kind of gas to boost you in the air. The fuel can only be made on a iland named paradise. To use it you have to go through training that tooks three whole years and you can only train there if you go to the military after the training but the most fail to learn it. It is attached to you with strips all over your body and it has controlers that you hold in both hands. With them you can control how much gas you want to let out and wich direction you want to fly. It's mostly used to kill other armys because it's really hard for them to shot you down while you are in the air. The most skilled person who uses ODM is Levi Ackerman.
