Tomori Kusunoki will be stepping from her role as student council president and idol Setsuna Yuki/Nana Nakagawa in Love Live! Nijigasaki High School Idol Club due to medical circumstances.
An announcement from the Love Live! Twitter account revealed that the proposal came from Kusunoki following medical consultations. It states that her physical conditions make it difficult for the voice actor and artist to perform live.
With her proposal being accepted, Kusunoki will “completely leave ‘Love Live! Nijigasaki High School Idol Club’ project” on March 31, 2023. However, the “episodes” of the Love Live! School Idol Festival All Stars mobile game that were recorded with her voice will continue to be used.
“Although Tomori Kusunoki will leave her roles of Yuki Setsuna and Nana Nakagawa, her legacy will always be remembered,” said the announcement.
Auditions for a new Setsuna Yuki/Nana Nakagawa voice actor are currently ongoing.
A separate notice on the Sony Music Japan website stated that Kusunoki was diagnosed with Ehlers-Danlos syndrome this September. She is said to have started to experience pain and numbness in Spring 2021 and began having medical examinations that year. Her health issues were first revealed in April 2021.
Born in 1999, Kusunoki made her voice-acting debut in 2017 and was announced as the voice of Setsuna — the idol persona of Nana — in September of that year (the original Nijigasaki girls were first introduced as part of the Love Live! School Idol Festival game’s PERFECT Dream Project anniversary project).
Outside of Setsuna/Nana in the two seasons of Love Live! Nijigasaki High School Idol Club and the upcoming Nijiyon, Kusunoki’s other anime roles include Hisame in To Your Eternity Season 2, Futaba Igarashi in My Senpai is Annoying, Neiru Aonuma in Wonder Egg Priority, and Hazuki Kagimura in Märchen Mädchen.
