Ken Naoko's role in Downtime is a supporting part built around physical transformation. She plays Yuriko Sakashita, a 75-year-old widow who has terminal cancer and seeks full-body plastic surgery. The casting was announced through the September scene photos, which listed her among the series' performers alongside Mayu Matsuoka, Riisa Naka, Shotaro Mamiya, Minami Tanaka, Reiji Nakagawa, Koki, Hana Amano, Yumi Adachi, and Shunsuke Kazama.

By October, director Yuki Saito described what the role required. Filming was grueling, and Ken sometimes arrived around 3 a.m. for three hours of special makeup before shooting began. She stayed playful on set, keeping the mood light with jokes. Because Sakashita has terminal cancer, Saito told Ken to lower her voice and speak hoarsely. The special makeup was trial-and-errored to show the surgery's before-and-after; before the operation, her character looks so wrinkled that another character says, "You're all skin and bones."

The special makeup for patients was handled by a team led by Amazing JIRO, with custom-made prosthetics applied to each actor to reproduce the process from immediately after surgery through recovery to the final result. Cast members including Hana Amano and Yumi Adachi underwent transformations without dubbing. Saito said a year of preparation made the special makeup possible, something he called difficult for terrestrial TV dramas.
