==History==
===Background===
Keiji Uraga was originally a scientist who became a test subject for Faust. He was forcibly transformed into the Zebra Lost Smash and then beaten to death to extract the Zebra Lost Bottle. Although he was given a second chance of life in the New World, Uraga regained his previous memories after Killbus unleashed the Pandora Box that affected those experimented with Nebula Gas. He took on a goal which he couldn't accomplish before, becoming the ruler of the world by creating a terrorist organization Down Fall, using Simon Marcus as a figurehead.
===Build NEW WORLD: Kamen Rider Grease===
Keiji Uraga arrived in Down Fall's raid in the Touto Government and turned the soldiers into Phantom Crushers. He ensured the Kamen Riders wouldn't get in his way as the Phantom Crushers extracted their Hazard Levels to prevent them from transforming. After acquiring a new model of the Build Driver and the Hazard Trigger, Uraga could transform into Kamen Rider Metal Build. He later learns that Kamen Rider Grease and the Hokuto Sanbagarasu were immune to Phantom Crusher's affects and can still transform. While Uraga was intrigued by this, but was focused in capturing Misora Isurugi, unaware that Vernage is no longer within her.
Uraga later kills Simon Marcus to assume his leadership of Down Fall. Eventually, the Kamen Riders manage to regain their ability to transform after drinking a concoction of Nebula Gas. Once Kazumi Sawatari arrived to rescue Misora as Grease Blizzard, Uraga uses the White Pandora Panel to evolve himself with a new form, which he dubs "Phantom Build". However, Kazumi transforms into Grease Perfect Kingdom to soundly vanquish Phantom Build. As he fades away, he questioned how Kazumi got stronger, which Kazumi replying that Uraga had nothing to fight for. His body dissolves and leaves behind the White Pandora Panel.
==Video Game Appearances==
===Kamen Rider Buttobasoul===
Phantom Build is a playable character in Kamen Rider Buttobasoul.
==Personality==
Keiji Uraga is a power hungry man and will use any method to achieve his goals, much like any higher ups of Faust during the previous world. For example, he coldheartedly shoots Simon Marcus to death when he reveals to betray him and take over as the leader of Down Fall.
He is very sensitive to be called either number two or being inferior to the one he faced as it would drive him mad, albeit he didn't show his anger brightly. Upon utilizing his plans, Keiji is calm and cautious, and whenever his plans worked splendidly, he would smirk in satisfaction before he reaches his final goals.
When his plans didn't work, however, he loses his cool to a degree, going as far to kill the Down Fall member who brought him the fake Last White Pandora Panel. Other negative traits include being extremely arrogant, openly doubting the ideals of his enemies. He told Misora that heroes are just mere fantasies, and even mocks Kazumi's bonds with his comrades. This worsens when he merges with the Last White Pandora Panel to become Phantom Build, along with increased aggression as well.
All of this proves to be Keiji's fatal flaw, with him being defeated by Grease Perfect in the end. Even when he was vanishing, he still doesn't understand why he lost against him.
