Ayako Kawasumi
When "Angel Sanctuary" was adapted into an audio drama series, Yuki participated in selecting voice actors; around two to three auditioned for each role. Ten, however, auditioned for the role of Setsuna, with Kenji Nojima ultimately chosen. Ayako Kawasumi provided the voice of Sara, while Takehito Koyasu and Yuuko Miyamura voiced Sakuya Kira and Kurai, respectively. For Arachne, Yuki envisioned a "transvestite" voice actor, which proved to be unfeasible. The antagonists Katan and Rosiel were voiced by Shin-ichiro Miki and Nozomu Sasaki, respectively. Yuki attended several sessions, during which she directed the voice actors and helped them with their interpretations of the characters.
