Update January 29
The official website for the TV anime has announced a change to the cast member. Sara Garandou will be voiced by Hibiku Yamamura (Hina Logi: From Luck & Logic) instead of Rie Murakawa. The reason for cast member change is that the anime staff members are unable to answer the request done by Haikyo, the agency Murakawa is in, about changing the content. Haikyo is really sorry for troubling the production team, so they suggested Yamamura, who is also in Haikyo, for replacement.
