Gate

Gates (ゲート) are what humans with magical potential. Whenever a Gate gives in to despair, they create a monster called a Phantom. Thus, they are pursued by the Phantoms, who seek to create more of their kind. From there, the created Phantom proceeds to tear down the host's Underworld (精神世界<アンダーワールド>), the subconscious of the human, before destroying the host itself. Able to assume its host's form, the Phantom proceeds to seek out more Gates and place them deep in despair to repeat the cycle. If Kamen Rider Wizard stops the sacrifice, he can use an Engage Wizard Ring to remove the feelings of despair and prevent Phantoms from destroying the host's Underworld with the host made a normal human.
