Recently, as part of a fifth-anniversary streaming event earlier this year, it was revealed that a third series is in the works for broadcast with Yuki Yuna Is a Hero: The Great Full Blossom Arc.
The first season was done by Studio Gokumi with direction by Seiji Kishi based on scripts and composition by Makoto Euze.
It’s been quite a few years since the debut of the first season of Yuki Yuna is a Hero but the show was definitely one of those properties that drove a lot of attention at the time.
Now, the official site has updated with a new promotional video below that has confirmed an October 1st, 2021 debut for it.
