- "Nice line, It's very touching. Now it's completely meaningless."
- ―Junichi Kaito[src]
- "Once I become the next Fourteen, I shall rule this world!"
- ―Junichi Kaito's true motive[src]
Junichi Kaito (海東 純一 Kaitō Jun'ichi) is Daiki's older brother within his home world and Junichi Shimura's incarnation from Kamen Rider Decade. He transforms into Kamen Rider Glaive (仮面ライダーグレイブ Kamen Raidā Gureibu, Masked Rider Glaive).
Like Daiki, Junichi is also a Kamen Rider, 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.
