Iori Saeki
Iori Saeki is an actor, born 1994.
Music came first, and under a different name. Saeki, born in Kanagawa in 1994, began in 2012 as a self-releasing singer working as NU-KO, and did not start voice acting until 2018, which is late enough that her earliest anime credit is a costumer with a couple of lines in Revue Starlight.
The climb afterwards is quick and easy to trace. King Halo in Umamusume: Pretty Derby is the part that stuck, and the franchise kept handing it back: the main series, the short-form spin-offs Umayon and Umayuru, and two films in 2024. By 2022 she was carrying a series outright as Menou in The Executioner and Her Way of Life, and the leads kept arriving after it, Yashiro Chikama in Adachi and Shimamura, Vanilla in Nekopara, Ashley in Lapis Re:LiGHTs, Kimie Kamata in ORESUKI, Maiko Kurashiki in Cinderella Nine.
What the list shows is range rather than a niche. She does the loud comic register and the quiet one with equal frequency, Tsubaki in The Quintessential Quintuplets and Mika in Akebi's Sailor Uniform on one side, Kano Minami in SSSS.DYNAZENON on the other, and she still takes unnamed background parts in features such as Weathering with You. The singing stayed in the job too, which is the sort of double skill that keeps a voice actress booked across a franchise rather than a single show.

Where to start with Iori Saeki
King Halo has followed her across half a dozen formats since 2018, so Umamusume: Pretty Derby - Beginning of a New Era is the natural way in. It is also the loudest version of her, which makes it a slightly misleading introduction.
So follow it with The Executioner and Her Way of Life, where she leads a much darker fantasy series and has to hold a controlled, cool performance for a full season. That pairing gives you both ends of what she can do.
Adachi and Shimamura and The Quintessential Quintuplets are the gentler side, quiet character work in shows built on small interactions. SSSS.DYNAZENON is the best-made production on the list by some distance and worth watching regardless of who is in it. ORESUKI Are you the only one who loves me? and Nekopara are for people who have already decided they like her.
