Saiki Kusuke/Inventions

Control Device (Limiters)

 * 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 and before the device was used by Kusuo, he was said to be very powerful when he was only 11 years old, having a telepathic range of the entire Japan, with Telekinesis that could easily lift up Roppongi Hills, and could effortlessly destroy the moon. He was also capable of exploding his entire house just by tossing and turning in his sleep.

Telepath Canceller

 * The device has the capability to disable the telepathy of Kusuo, unabling him to read Kusuke's 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

 * The device that is capable of going to and fro the past and the future. It was first introduced in one of the parallel world in the series, "The Modified 2014" where the future Kusuke explains how he created the time machine personally just to revive Kusuo who had died that year. It was revealed by Reita that Kusuke was the reason for the World War 3 but Kusuke explains he just indirectly did it when people fought for the time machine he invented.

K-Watch

 * Another device that was introduced in "The Modified 2014". It has the feature of displaying hologram image in the air.
