Ami Koshimizu voices Töregene in Jaadugar: A Witch in Mongolia, Riina Yamabuki in the 2027 second season of Tune in to the Midnight Heart, Eleanor Northbrook in Vertex Force, and Lefy in I Became a Legend After My 10 Year-Long Last Stand. Her earliest 2003 lead role, Nadja in Ashita no Nadja, is being streamed in full on the Toei Animation Museum Channel.
Ami Koshimizu's recent credits run across four 2026 television and streaming anime, all announced between late May and late August. In Jaadugar: A Witch in Mongolia, the adaptation of Tomato Soup's manga, she voices Töregene alongside Kenji Nojima, Hiro Shimono, and Daisuke Namikawa. In Vertex Force, she voices Eleanor Northbrook, an 18-year-old from the United States, in a cast led by Makoto Koichi and Kaede Hondo. In the second season of Tune in to the Midnight Heart, she voices Riina Yamabuki, one of Arisu's elder sisters. In I Became a Legend After My 10 Year-Long Last Stand, she voices Lefy, the healer of the former legendary hero's party.
The four roles are spread across different production pipelines. Vertex Force is an original anime directed by Kazuhiro Takamura at SMDE, with assistant director Gorō Kuji, engine design by Kanetake Ebikawa, and ENIA design by JNTHED. Jaadugar: A Witch in Mongolia is produced by Science SARU, with Naoko Yamada as chief director and Abel Gongora as director. Tune in to the Midnight Heart returns in 2027 from NBC Universal with director Masayuki Takahashi and key staff intact. I Became a Legend After My 10 Year-Long Last Stand premiered on Amazon Prime Video on July 3, then on other services and TV on July 6.
Two of the roles place Koshimizu in family or party ensembles built around a lead younger than her character. In Tune in to the Midnight Heart, Kaede Hondo also appears as Mito Yamabuki, the other sister, making the Yamabuki pair part of the second season announcement. In Vertex Force, the cast spans four countries of origin for its characters, with Megumi Han, Rie Takahashi, and Hondo joining Koshimizu as Eleanor, Lala Zudenstein, and Yoko Nishina. In I Became a Legend After My 10 Year-Long Last Stand, Lefy belongs to the former hero's group and appeared in the anime's eighth episode.
Koshimizu's earlier work is also back in circulation. The Toei Animation Museum Channel began streaming all 50 episodes of Ashita no Nadja on September 23, with episode 1 at 18:00 and one episode following each Wednesday, free for two weeks. The 2003 Toei Animation original series follows Nadja, a girl raised in an orphanage in early 20th-century Europe, searching for her mother. Coverage of that run notes the series aired between Ojamajo Doremi Dokkaan! and Futari wa Pretty Cure and drew less attention than either.
