The upcoming spinoff series Kibou no Chikara: Otona Precure ’23 will premiere later this year.
This spinoff series is about life after being a magical girl and follows Yumehara Nozomi as an adult in the year 2023.
Nozomi was the star of Yes! Pretty Cure 5 which aired in 2007. If the series follows the same timeline that would mean she’d be approximately 30 years old in the new series.
Not much is known about the plot for the series at the time of writing but more details ought to be coming before the premiere.
Kibou no Chikara: Otona Precure ’23 will premiere this October as part of the Fall 2023 anime season.
