驚爆危機
In 2003, Rial voiced best-friend character Kyoko Tokiwa in "Full Metal Panic!", and got to reprise her for "Full Metal Panic? Fumoffu" and "Full Metal Panic: The Second Raid". In the same year, Rial voiced Kirika Yumura, the quiet assassin partner in "Noir". Rial said that Kirika was challenging because she had very few words but had to convey a lot of emotions. She also noted that Kirika's personality changed over the course of the series, so she voiced her to be more emotional in later episodes which drew some criticism from fans. She also voiced Lila in "Najica Blitz Tactics" where she also got to do a DVD commentary along with fellow actress Kira Vincent-Davis. The commentaries have become popular as she receives feedback from fans about them at anime conventions. She voiced female protagonist Haruka Shitou in the sci-fi show "RahXephon".
