Goro Yura

Goro Yura (由良 吾郎) is Kitaoka's loyal servant who is highly skilled with household work and hand-to-hand combat. He is also aware of Kitaoka's activities as a Rider and helps as much as he can.

After his master's death, Goro briefly inherited his mantle as Kamen Rider Zolda (仮面ライダーゾルダ) until his own death at the hands of Kamen Rider Ouja.

History
25 year-old Goro is Kitaoka Shuichi's devoted loyal servant, willing to do anything for him but not blindly. He is capable in hand-to-hand combat, so it was quite simple for Shinji to assume he was Kamen Rider Zolda. He handles household work such as cooking and cleaning, giving massages, and taking professional photographs. Goro was once Kitaoka's client and because of that, Kitaoka's condition was not diagnosed in time. Feeling indebted, Goro decided to be his loyal servant and bodyguard forever.

Kitaoka won't ask him to do things that are fundamentally wrong except for pretending he's dead and have Shinji stuff the body in the car. He has been known to disapprove of Kitaoka's actions and is able to coerce Kitaoka eventually. Later on, he comes to disapprove of him fighting as a Kamen Rider but he does not ask him to stop. He does intentionally tries running Asakura over with a car, but Kitaoka prevents this and scolds Goro, pointing out that it's his business to take care of.

Goro does like Shinji, knowing he meant no harm to Kitaoka and wouldn't hurt a fly under normal circumstances. When Kitaoka died, Goro took his boss's place as Zolda, only to be defeated by Asakura.

When Shiro Kanzaki altered the timeline so that the Rider War never happened, Goro was brought back to life alongside Kitaoka.

Rider Time Ryuki
For unknown reasons, Goro is devoted to Takeshi instead of Kitaoka. On the fourth day of the returning Rider War, he insists himself to be with Takeshi after he rescued him from a horde of Mirror Monsters when Takeshi faced off Ren. After Takeshi seemingly gives up on beating Goro because he wouldn't let him go, Goro served him food which satisfies Takeshi, making him choose on killing Goro for the last. On the fifth day of the Rider War, he works alongside Takeshi to wipe out the rest of the survivors of the Rider War.

Kamen Rider Zolda
Kamen Rider Zolda Rider Statistics Ability Perimeters Zolda is a far-range Kamen Rider, using different forms of heavy artillery to fight. His default weapon is his Magna Visor (マグナバイザー) which doubles as a submachine gun with a cyclic rate of 120 rounds per minute. Using his Card Deck, Zolda can conjure up additional weapons that form from his Contact Monster's body such as the Giga Launcher bazooka, the Giga Cannon backpack, and a huge Giga Armor shield. In his Final Vent End Of World (エンドオブワールド), Zolda summons Magnugiga in front of him, inserting his Magna Visor into the monster's back to have it fire all of its arsenal at once at the enemy and the surrounding area.
