Takashi was the original Blue Lion's second-in-command and wore a black uniform while piloting it. He was around Akira's age and died from injuries sustained during an attack by Honerva in episode 6. His heroic deeds earned him a burial befitting his status. Fala replaced Takashi as the Blue Lion's pilot, and he had a younger brother named Ryou who joined the heroes to fight against the Galra Empire. Like his brother, Ryou also perished in battle. "Shirogane" is Japanese for silver.
