==History==
===Lost World===
A group of Riotroopers appear and start attacking people, but are defeated by Kusaka as Kamen Rider Kaixa, who does it on his own.
Mihara as Kamen Rider Delta meets up with Kusaka and Mari, and another Riotrooper appears. This Riotrooper, the Riotrooper ver. 2, has a different appearance from the others and is equipped with the Faiz Edge. Kaixa and Delta fight him, damaging his helmet and revealing his identity as the Rose Orphnoch.
With Kaixa and Delta being unable to stand up to the Riotrooper v2, they run away with Mari. However, thinking that it was Mihara who sent Mari the roses, Kusaka grabs and tosses him back at Murakami, remarking that he deserves it for daring to send flowers to his beloved woman. Mihara screams that it is a misunderstanding and for Kusaka to help him. Kusaka instead sneers as a blue petal lands on Mihara's outstretched hand, turning him to ash.
Back at their home, Takumi asks Keitaro what happened to Mami, a young girl the two had found and taken in, having left her with him before heading off to look for Mari and Kusaka. Keitaro points to a small human-shaped pile of ash, revealing that she was an Orphonoch as well. Kusaka reveals that he killed the girl himself before she could transform into an Orphnoch much to Takumi's anger. 
===Paradise Lost===
In the alternate reality movie Kamen Rider 555: Paradise Lost, Masato joined the Human Liberation Army to defeat as many Orphnoch as he could while aiding them by chances. Masato arrogantly claimed that he is the only humanity need, not Faiz and not even need to steal the Emperor Gear.
During the raid of the Orphnoch to Human Liberation Army base, Masato was overpowered and killed by Leo, an Orphnoch who is chosen to use the second strongest Emperor Gear, Psyga. Keitaro Kikuchi briefly wore the Kaixa Gear by drinking the experimental transformation elixir, and killed the Lion Orphnoch. Due to the elixir, Keitaro was unharmed. However, when the formula ran out, the Kaixa Gear disintegrated instead.

Once transformation is completed, the Kaixa Armor has several key features in its design to protect protection to the user. Like all gear, the Kaixa armor manifests when the Kaixa Driver generates Photon Blood, a glowing substance generates the soft Sol Foam suit, Sol Metal armor, and Fullmetal Lung chest armor via traveling through the two yellow Photon Streams lines that gives Kaixa "greater strength at the cost of speed". The steams end at the Photon Terminals at the gauntlets and Power Anklet greaves, the right Anklet having a Energy Holster that the Kaixa Pointer can be connected it. The helmet is unique due to its Global Feeler antenna to link up to Smart Brain's networks and the X Finder visor that gives Kaixa incredible vision to see in darkness, giving the illusion of a glowing eye, and a limited amount of x-ray vision.
