|This article is about a/an rider in Kamen Rider Decade.|
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.
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.
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.

- DragKnuckle (ドラグナックル Doragunakkuru): A panel made of Armetal that covers the back of the hand. When this material hits the enemy, the power of the punch that Ryuki delivers is maximized.

Behind the scenes
- "Tatsu" is the Kun'yomi method of how to pronounce Dragon (竜 ryū).
- His Final Form Ride transformation bears a striking resemblance to RyuuRanger's personal mecha: Mythical Chi Beast RyuseiOh.
- 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.
