|This article is about a/an Rider in Kamen Rider Ryuki.|
Shinichi Kido (城戸慎一 Kido Shin'ichi) is Shinji Kido's twin older brother. The two looked exactly the same but had different personalities. While Shinji is gentle, friendly, and naive, Shinichi was more aggressive. Nevertheless, they got along very well and were really close. However, one day, when a thug pointed his knife to Shinji, Shinichi died while protecting his younger brother. It was later revealed that the thug was a person whom Shinichi had fought before and was after him in the first place, and had gotten them mixed up due to their similarities.
After Shinji (as Ryuki) mistook the Trick Vent clone of Kamen Rider Knight supposedly dying in battle with Ouja, his overwhelming emotions led to his body being possessed by the spirit of his late older twin brother, Shinichi Kido. Looking at the dead bodies of Ouja and Zolda (who also died after caught in the explosion of his own attack), Yui Kanzaki stated he had done it, and when doing so he and Dragreder turned black, turning into Ryuga. Ren shows up revealing that he was never present; the Knight that Ouja had killed was a copy made with Trick Vent. With Knight and Shinji as the last two Riders remaining (in this version Kamen Rider Odin works as the one who only grants the wish rather than fighting for it) and have to fight. With Shinichi emerging as the victor, Odin was summoned while granting a wish which is to revive all of the victims of the Rider War.

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. Shinichi transforms into Ryuga after possessing Shinji's body. 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.
