In Episode Six, it is revealed Empress Katsumi set up Ryo for the murder of her husband so her son Hiro could become Emperor.
In Episode Nine, Empress Katsumi sent Akita to meet Ryo in her son's place. This lead to Hiro being upset at her for making him a liar as he had promised Ryo it would be him to go. Katsumi tried to soothe her son by telling him she had just made him Emperor.
In Episode Twenty-Five, Empress Katsumi is confronted by her son Hiro about the death of her husband. The revelation to Hiro and the blink drive that his brother has in his position prompts him to give his throne to Ryo. When Katsumi learns of this, she places Hiro under house arrest, claiming he was injured in an assassination attempt.
Later, Katsumi has Ryo captured with the aid of her Seer allies future sight, and has Ryo put on trial for her husbands death. During his execution, Hiro is freed and interrupts right before Ryo is killed. He gives over the throne to Ryo and Ryo has the whole court abruptly murdered, including Empress Katsumi herself.
Empress Ishida has dark hair and wears many elegant robes.
