For the original Kamen Rider Ryuki, see Shinji Kido.

Shinji Tatsumi (辰巳 シンジ Tatsumi Shinji) is the resident Kamen Rider of the World of Ryuki in Kamen Rider Decade.

Shinji Tatsumi

Shinji Tatsumi is a young man who worked for the Atashi Journal as its photographer alongside its top writer Ren Haguro until he left the Journal three years ago without explaining himself. Since then Shinji was distraught and felt betrayed as a result. However, when his editor Reiko Momoi is mysteriously murdered, Shinji finds Ren present at the scene. Soon after, Shinji is chosen to become Kamen Rider Ryuki, though is reluctant to join the Kamen Rider Trial that would judge the fate of the suspected murderer: Natsumi Hikari.


As the trial begins, Shinji crosses paths with Yusuke Onodera and Tsukasa Kadoya, who represents Natsumi as her defense attorney. After telling them what the official sources say behind Reiko's death and admitting he feels that Natsumi's innocent, Shinji accompanies Tsukasa and Yusuke to the crime scene to meet Kamata who confirms Ren's appearance at the Journal around Reiko's death. While Kamata and Tsukasa enter the Mirror World to fight, Shinji confronts Ren to demand what he was doing at the Atashi Journal. Once in the Mirror World, Shinji challenges Ren as he believes that Ren is the true murderer and has framed Natsumi. However, their fight is interrupted once Decade appears and challenges Knight with Ryuki watching their fight with contempt for Knight. Shinji later uses the Time Vent card Ren had acquired to reverse the flow of time, saving Reiko Momoi from murder, discovering the reason why Ren left the group 3 years ago, and exposing Kamata as the murderer. Along with Decade, Shinji fights Abyss, revealing that Kamata is actually the Paradoxa Undead.

He later appears in Kamen Rider × Kamen Rider W & Decade: Movie War 2010 alongside the other Riders of the Nine Worlds to help in reviving Tsukasa and helps him battle Super Shocker, assuming Ryuki Survive with the help of Decade's K-Touch and later into his Ryuki Dragredder form with the All Rider Final Form Ride Card to fight the Super Crisis Fortress.

Kamen Rider × Kamen Rider W & Decade: Movie War 2010


Ryuki harassed by Decade Violent Emotion

Tatsumi as Ryuki, alongside Blade attacked Tsukasa in a warehouse. They throw him out and continue attacking, forcing him to transform and face them. Tsukasa transforms into Decade Violent Emotion and destroys Ryuki using the Blade Final Form Ride Blade Blade, immediately afterwards destroying Blade and collecting the Kamen Ride cards that fell after their disappearance. This Ryuki isn't shown in the movie again, although he's presumably restored alongside the other Riders afterwards.

Later appearances

Movie War 2010 currently remains the last appearance of Shinji Tatsumi. The Ryuki that appears in OOO, Den-O, All Riders: Let's Go Kamen Riders and Kamen Rider × Super Sentai: Super Hero Taisen is the original Ryuki, Shinji Kido.

Through the use of his Sword Vent Advent Card, Ryuki can arm himself with the Drag Saber (ドラグセイバー Doragu Seibā), a sword derived from Dragreder'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 Dragreder's head. With the Drag Claw, Ryuki can perform the Drag Claw Fire (ドラグクローファイヤー Doragu Kurō Faiyā) attack with Dragreder, in which he and Dragreder each launch a fireball at the opponent.

Kamen Rider Ryuki Survive (仮面ライダー龍騎サバイブ Kamen Raidā Ryūki Sabaibu) is Ryuki's final form, assumed using the Survive Rekka Advent Card, though Tatsumi only achieved it with the aid of the K-Touch. The Survive Rekka card transforms the Drag Visor into the the Drag Visor-Zwei. Transforming into Survive form also causes Dragreder to transform into Dragranzer. Survive Form enhances all of Ryuki's stats, allowing him to surpass all other Riders, with the exception of those who are also using a Survive Advent Card, such as Knight Survive and Odin.

Using the Sword Vent Advent Card converts the Drag Visor-Zwei to a blade mode named the Drag Blade (ドラグブレード Doragu Burēdo).The Drag Visor-Zwei can also function as a ranged weapon by shooting fireballs. By using the Shoot Vent, Ryuki can perform the Meteor Bullet (メテオバレット Meteo Buretto) attack alongside Dragranzer, in which he and Dragranzer each launch a fireball at the opponent.

By using his Final Vent, Ryuki Survive can perform his final attack, the Dragon Fire Storm (ドラゴンファイヤーストーム Doragon Faiyā Sutōmu), which transforms Dragranzer into a bike for Ryuki to ride. Ryuki drives toward the enemy and performs a wheelie, followed by Dragranzer shooting several opponents at the opponent from its mouth. Finally, Ryuki slams into the opponent, destroying it.

This form is exclusive to W & Decade: Movie War 2010.

―Transformation announcement[src]

Kamen Rider Decade's Final Form Ride allows Ryuki to change into Ryuki Dragreder (リュウキドラグレッダー Ryūki Doragureddā). This automatically equips Ryuki with Guard Vent and Sword Vent. While the first transformation required Decade's assistance, Ryuki eventually was able to transform at will into this form. Ryuki can also shoot fireballs from his mouth in this form.

Behind the scenes


Shinji Tatsumi is portrayed by Momosuke Mizutani (水谷 百輔 Mizutani Momosuke). As Kamen Rider Ryuki, his suit actor is Jun Watanabe (渡辺 淳 Watanabe Jun).


  • "Tatsu" is the Kun'yomi method of how to pronounce Dragon ( ryū).


  • His Final Form Ride transformation bears a striking resemblance to RyuuRanger'sIcon-crosswiki personal mecha: Mythical Chi Beast RyuseiOhIcon-crosswiki.
  • The difference between Kido's view on Akiyama and Tatsumi's view on Haguro is that Kido is very kind towards Akiyama. While Tatsumi on the other hand, became extremely cold on Haguro, even supspecting him as the killer of Reiko.
