Kaori Tanaka (田中 香, Tanaka Kaori, born April 18, 1969), also known by her pen name, Soraya Saga (嵯峨 空哉, Saga Soraya), is a freelance Japanese illustrator, designer, and video game story writer.
Saga joined Squaresoft as a graphic designer in the early 1990s through an advertisement in ASCII computer magazine.
[1] Saga and her husband Tetsuya Takahashi submitted a script for Final Fantasy VII which was called "too dark" and "complicated" for a fantasy game, but were allowed to start a new project based on the script, which was worked into a full treatment with cutscenes, eventually being released under the name Xenogears.
[3] The story was inspired by the writing pair's interest in Jung, Nietzsche, and Freud, addressing questions of "where do we come from, what are we, where are we going".
[3] KOS-MOS was designed by Takahashi, reflecting a reversed view of human construction, giving the character a powerful body and fragile soul.
