The Z Holder (ゼットホルダー Zetto Horudā) is a container which Haruki Natsukawa and Riku Asakura use to keep their collection of Ultra Medals. Despite its obvious appearance, the holder is made from an extraterrestrial mineral that is invisible to normal humans.
The container is usually placed on the right side of their users' belts. It opens like a normal container and has the capacity of housing 20 Ultra Medals altogether.
- Appropriately as the Z Riser replaces the Geed Riser as Riku's transformation item, the Z Holder replaces the Ultra Capsule Holder by taking the same place it was previously held on Riku's belt.
