Iku Sutou (CV: Rie Takahashi) is a character credit associated with Japanese voice actress Rie Takahashi (高橋李依), who was born on February 27, 1994, in Saitama Prefecture, Japan. Takahashi has built a steady profile in anime through roles that often extend into character songs, cast recordings, and other music-related releases, and her official website is taka8rie.com.
The credit is especially relevant for Re:Zero − Starting Life in Another World, where she voices Emilia. In 2026, coverage around the series’ fourth season again drew attention to her with the "Stay Alive ～Regain～" singing footage and new promotional visuals, and she also made her first solo appearance at Animelo Summer Live by performing "Stay Alive ～Regain～" on stage. For anime music listeners, the entry helps connect the character, the voice actress, and the ongoing Re:Zero soundtrack and promotional activity in a searchable format.
