|This article is about a/an rider in Kamen Rider Decade.|
Kamen Rider Ryuga (仮面ライダーリュウガ Kamen Raidā Ryūga, Masked Rider Ryuga) was a Dark Rider who murdered and assumed the guise of the Negatives World counterpart of Hirohiko Sato (佐藤 博彦 Satō Hirohiko), Natsumi's TG Club high school classmate. He was destroyed by Decade Complete Form with the Ryuki Survive Final Kamen Ride.
Earlier, in the World of Faiz, Narutaki summoned a version of Ryuga to finish off Decade, who at the time was unable to transform. This one was defeated by Diend using the Kiva Arrow.

Kamen Rider Ryuga is a dark, Mirror World version of Ryuki. He is contracted to Dragblacker, a dark version of Ryuki's Dragreder. His Visor, the Black Drag Visor (ブラックドラグバイザー Burakku Doragu Baizā), is equipped on his left arm. Like Ryuki, Ryuga's parameters are balanced. However, they are heightened to the point where Ryuga is the strongest out of all of the 13 Riders, with the exception of those using a Survive Advent Card.
Through the use of his Sword Vent Advent Card, Ryuga can arm himself with the Drag Saber (ドラグセイバー Doragu Seibā), a sword derived from Dragblacker's tail. His Strike Vent arms him with the Drag Claw (ドラグクロー Doragu Kurō), a gauntlet capable of shooting fireballs that is derived from Dragblacker's head. With the Drag Claw, Ryuga can perform the Drag Claw Fire (ドラグクローファイヤー Doragu Kurō Faiyā) attack with Dragblacker, in which he and Dragblacker each launch a fireball at the opponent. His Guard Vent equips him with the Drag Shield (ドラグシールド Doragu Shīrudo), two shields derived from segments of Dragblacker's body that can be held by hand or mounted on Ryuga's shoulders.
By using his Final Vent, Ryuga can execute his finisher, the Dragon Rider Kick (ドラゴンライダーキック Doragon Raidā Kikku), in which he jumps into the air with Dragblacker flying behind him. Dragblacker then breathes dark blue fire at Ryuga, propelling him into a flying kick that strikes the enemy.
