Haruka Shiraishi has four anime roles announced across four series. She is set to voice Hisako Kotobuki in Even the Student Council Has Its Holes!, which premieres in October 2026, and appears in the cast of The Demons Are Planning Something Good, due for a 2027 television debut. Two further series, Yowaki MAX Reijo and Witch and the Mercenary, have announced her in their casts.
Haruka Shiraishi's recent announcements are spread across four separate productions. In July 2026, two casts confirmed her. She was revealed as Hisako Kotobuki in the anime of Muchimaro's four-panel manga Even the Student Council Has Its Holes!, alongside Miyu Tomita as Komaro Michinoku, with the series set to premiere in October 2026 and Shogo Sakata starring as protagonist Mizunoe Ume. Days earlier, she was named among the cast of The Demons Are Planning Something Good, the television anime of akuji Kato's comedy manga, set for a 2027 television debut. That production is directed by Takuya Asaoka at TNK, with Kazuyuki Fudeyasu on series composition and Hiraku Kaneko on character design.
In September 2026, two more series added her to their rosters. Kadokawa announced the anime of Hiro Oda's Yowaki MAX Reijo with a promotional video, key visual, theme song artists, and an October 4 debut; Shiraishi is among the cast members revealed, though the announcement named Konomi Suzuki on the opening theme Goki MAX Sengen and Miku Ito on the ending theme Yoake Made ni. Separately, the anime of Kaeru Chohokiteki's Witch and Mercenary light novel series confirmed an April 2027 premiere on NTV and 29 affiliated channels plus BS NTV, with Shiraishi voicing Elicia Armel, a rank 3 staff-wielding adventurer. That production is directed by Shinpei Ezaki at 8-Bit.
Across the four stories, her roles range from a student council member in a four-panel adaptation to a staff-wielding adventurer in a light novel adaptation. Two of the series premiere in 2026 and two in 2027. No story states which role came first in the production process, and no story names her character in Yowaki MAX Reijo.
