Junichi Kaito

Junichi Kaito is Daiki's older brother within his home world, known as the Diend World. Like Daiki, Junichi is also a Kamen Rider, Kamen Rider Glaive, setting up the operation to overthrow Fourteen. However, Junichi was actually a double agent who worked to flush out the last two Kamen Riders of their world until Daiki unknowingly captured him, and as a result, played the role as Fourteen's puppet right hand in charge of the area management committee. However, once Fourteen is destroyed, freeing everyone else from the brainwashing, Junichi reveals the truth with intent to be the next Fourteen. In spite of not being able to kill Daiki, with Tsukasa affirming he still has his free will, Junichi considers his brother dead to him and leaves.
