Aoi Koga is attached to two October 2026 television premieres, playing Lasgul in Shuiro no Kamen and Bianca Miller in the second season of The Iceblade Sorcerer Shall Rule the World, and continues as Paimon in Genshin Impact, appearing on the Ver.7.1 preview program.
Aoi Koga's 2026 slate runs across television anime and a long-running game role. In June she was named among the additional cast for Dara-san of Reiwa, the adaptation of Haruomi Tomotsuka's manga, which premiered July 2 with an ending theme by REIRIE. The following month she joined the third season of The 100 Girlfriends Who Really, Really, Really, Really, Really Love You as Momiji Momi, a third-year middle school student, in a season that premiered July 5 on Tokyo MX.
September brought two more roles on the same day. She is in the six-name cast block for Shuiro no Kamen, playing Lasgul, ahead of an October 10 premiere on Yomiuri TV and Nippon TV's Saturday 5:30 p.m. slot, with MAN WITH A MISSION on the opening theme and yutori on the ending theme. She is also in the new cast for the second season of The Iceblade Sorcerer Shall Rule the World as Bianca Miller, with that season set for an October 8 debut on TBS, a BS11 airing the next day, and Crunchyroll streaming as it airs.
Her game work is the constant. She voices Paimon in Genshin Impact and was announced as one of the guests, alongside Kanae Ito and Sumire Uesaka, for the Ver.7.1 "Requiem of the Underworld" preview program on September 12, where the latest information was introduced. The game is available on PS5, Xbox Series X|S, iOS, and Android.
