Rika Takamiya

The Silver Legionnaire: "Do you really believe in your cause, or is that what you were engineered to think?"

Tailsilver: "I honor my code. That's what I believe."

Subject Delta-40 "Rika Takamiya", also known as Tailsilver, is the main protagonist of the Clones Arc of Twintail Rebellion S. Originally a clone created approximately three years after the Imperial-Twin-Tail war to serve as an agent of the Solar Empire to hunt down the remaining Twin-Tail warriors that survived the purge, she eventually went renegade after an attempted execution on her was made. Rika successfully staves off execution with the aid of her genetic template and "sister", Kirin Takamiya, but during the escape, the squad sent to kill Rika mistaken Kirin for her, and so she was presumed dead. Rika escapes to Earth and transfers to Yōgetsu Private Academy, where she crosses paths with Soji and the other Twintails. Rika was previously entrusted with a newly advanced Tail Gear by Kirin, allowing her to transform into Tailsilver in combat.

It is later revealed that Kirin used fragments of Silver Aquila's Tail Gear to forge Rika's, therefore making Rika an indirect successor of Aquila.

Her arsenal is the most diverse out of all the other Twintails, consisting of a pair of Clone Army DC-15s blaster pistols, two wrist flamethrowers, thermal detonators, EMP grenades, and a light-blue lightsaber. Like Aika/Tailblue, Rika is superbly proficient in unarmed combat, specializing in martial arts.

Later in the series, Rika volunteered her DNA for the New Republic army to use in order to create an elite unit of cloned soldiers known as Silver troopers.

After the fall of the Solar Empire, Rika, along with Aurina, was unanimously elected as a consul of the New Republic.
