Saiki Kusuke/Inventions

Control Device (Limiters)

 * Limiter.jpges 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.

Kusuke No.1

 * A simple robot that Kusuke made sometime in his childhood. It is controlled by a remote, which he uses to impress Kuniharu. It was later destroyed by a young Kusuo using his own robot which he made out of Pocky box and a couple of sticks.

Telepath Canceller

 * Telepathy Canceler.jpg device has the capability to disable the telepathy of Kusuo, preventing the latter from reading his thoughts. It's appearance is similar to that of Kusuo's control device minus the other antennae which it holds only one. This device ended Kusuke's research on telepathy.

Time Machine
