The Zipper ring
The Zipper is ring Dimensional ÄRM. While unactivated it is a ring with the image of a skull on the center of it. When the ÄRM becomes invoked it becomes a giant zipper that just hangs in space.
Its ability is that it allows the user to store his or her ÄRMs in an extra-dimensional space for storage. So when activated the user can unzip it and reach inside and grab whatever was previously stored. The main advantage of it is that it can be used in battle for a fast change of ÄRMs.
