Devices used to take control of Kusuo's psychic powers. The devices were first made by Kusuke when Kusuo was still a 5th grade student. It's original shape would be an antennae but it is referred as a "hairpin" due to Kusuo's hypnotic powers. When the device is removed, Kusuo's full psychic power goes out of control and multiplies by the amount of time his powers were limited. Removing his limiters where shown to depict the world's destruction. When the control devices were reinstalled, it would take time before his powers stabilizes. The control devices cannot stop the growth of Kusuo's power.
