Jun Shibaura

Kamen Rider Gai (仮面ライダーガイ, Kamen Raidā Gai?) is a fictional character in the tokusatsu production Kamen Rider Ryuki. He is one of the 13 Kamen Riders the story revolves around. His true identity is Jun Shibaura, age 21, and he is played by Satoshi Ichijou.

Fictional character biography
Jun is a 3rd year college student at Meirin University, extremely well-versed in computers and programming to be in the Matrix Netgame Club. Being the son of a company president, Jun is arrogant in personality, toying with other people's lives for nothing more than a good laugh. He joined the Rider war simply to be the winner of the Rider war, which to him was all a game. Jun even used his Matrix members to fight to the death in a game similar to the Rider war. Shinji began investigating the series of strange killings and found Jun, who reduced Ryuki to blank form by stealing his Dragreder card. He used both Shinji's card and the virus he uploaded to the ORE Journal mainframe to blackmail himself into their head of their company. Shimada eventually managed to wipe out his programming with her own virus, while Raja stole back the Dragreder card. Soon after, Jun was picked up by the police for his ties to the Matrix member murders, getting his father to bail him out with Kitaoka's aid.

Jun even went so far as to reveal the true identity of the other Riders among them, impressed with Kamen Rider Ohja's sadistic nature. To suit that end, Gai kidnapped Yui to start a "Rider party" between him, Kamen Rider Knight, Kamen Rider Raia, and Kamen Rider Ryuki. However, in the middle of the fight, their battle gets intertwined with the one between Kamen Rider Zolda and Ouja, who used Gai a shield to take the blunt of Zolda's Final Advent before killing him with his own. Gai's contract Monster, Metalgelas, was infuriated at his master's death and went after Ohja. He eventually fell victim to Ohja's contract card, becoming the second monster.

After the reset in the final episode, Jun lives again and bumps into Shinji, still the same rude person he's always been.

In the 13 Riders TV Special, Gai was consumed by the mirror monster, Death Spider.

Similar to Kamen Rider Scissors and Kamen Rider Tiger. Gai is a melee fighter who relies on brute strength and his intellect more often than anything else, Gai's attack methods usually involve his Confine Advent card to cancel any weapons from the other Riders while using the Metal Visor (メタルバイザー, Metaru Baizā?) on his left-shoulder to conjure his Metal Horn gauntlet as well as summoning his contract monster Metalgelas to fight alongside him and execute his Heavy Pressure (ヘビープレッシャー, Hebī Puresshā?) Final Vent, carried by his Contact Monster as a lance, with the Metal Horn extended in front of him to pierce through the opponent.

Contract Monster
Metalgelas (メタルゲラス, Metarugerasu?): Resembling a cross between a rhinoceros and a humanoid, Metalgelas was originally the contract Monster of Kamen Rider Gai. It later came into the possession of Kamen Rider Ohja and, together with Venosnaker and Evildiver, became one of the building blocks of the composite Monster Genocider. Metalgelas, derives it's name from the Greek river god Gelas. Although many depictions of Gelas are that of a bull-horned man, some contexts refer to is as "head of horns".
