Kaede Saionji is a character from the anime Ghost Concert: missing Songs. She is a teenage girl of high school age notable for her calm and collected demeanor. She comes from a distinguished family, which contributes to her poised and refined bearing. Physically, she is recognized for her long blue hair that reaches her hips or waist, styled with a hime cut, and she has matching blue eyes. Her typical attire is a school uniform.

In the story, which is set in the year 2045 where singing and the human creation of music have been outlawed, Kaede is a member of a psychic organization known as TERA. This group is engaged in a hidden conflict involving supernatural phenomena called the Possession Requiem and powerful otherworldly spirits known as Great Ghosts. Within this setting, her primary role is that of a fighter. Unlike the protagonist Seria Aiba, who battles by allowing a Great Ghost to possess her and sing, Kaede uses spiritual weapons to fight against the threats they face.

Her key relationships are primarily with her fellow members in the TERA organization. She works alongside other combatants such as Shuri Murayama, a straightforward fighter who wields a great sword. The group operates under the leadership of Setsutei, an unconventional monk, and his assistant Yotetsu. While her calm personality suggests she would be a stabilizing force within the team, specific details about her personal bonds with the other characters are not elaborated upon in available sources. Likewise, the search results do not provide information on her individual motivations, character development over the course of the series, or extensive details about the specific nature of her spiritual weapons and combat abilities beyond the fact that she uses them.
