Mutsuki Kamijo/Missing Ace

In an alternate story, Mutsuki Kamijo (上城 睦月) was bestowed the power to become Kamen Rider Leangle (仮面ライダーレンゲル). Five years after the sealing of the Joker Undead, he currently lives a normal life until coming out of retirement once the Undead resurface.

Missing Ace
In an alternate continuity, after Joker/Hajime was sealed, four years have passed and Mutsuki has tried to forget about being a Kamen Rider, working to have a normal life again. His first day of work turns out to be a disaster as both of his employers fight much to Mutsuki's dismay. This was abruptly put aside when he witnesses the Category Ace of Clubs and was compelled to transform into Kamen Rider Leangle. Together with Kenzaki, Tachibana, Kotaro, and Shiori, they figure out that Kamen Rider Glaive is really the Albino Joker that everyone is looking for. But he still manages to take the ancient power and use it on the Riders. But thanks to Hajime's sacrifice, he, Blade, and Garren were able to defeat the Albino Joker and save the world once again. He is last seen at Amane's fourteenth birthday party.

Forms
The Leangle system was developed through tricks and manipulation by Isaka, the Peacock Undead, who needed the sealed Spider Undead to complete it. However, as later revealed, the Undead was not sealed properly and thus manipulated his users for his own agenda. For Mutsuki to change into Leangle, he has to insert the sealed ♣A: Change Spider card into his Leangle Buckle and position his buckle in front of his waist. The belt then expands automatically around his waist. Mutsuki makes a motion with his right hand across his face and says "Henshin!", then manually opens a portion of his buckle. The buckle announces "Open Up!" at this point. This would also cause a violet projection with a spider image to come out before him. Unlike Blade and Garren's method of transformation (running into their projections), Mutsuki's projection comes to him and completes his transformation into Leangle.

The same "Open Up" system would be used for the Rider Systems of the movie-only Riders Kamen Rider Glaive, Kamen Rider Lance and Kamen Rider Larc.

Kamen Rider Leangle can be assumed by using the Leangle Buckle and Change Spider Rouze Card. The transformation fuses the user with the DNA of the Spider Undead. Leangle's Ace form has higher ability parameters than Blade and Garren, allowing him to compensate for the fact that he cannot assume other forms like them.
