Spy Classroom’s Grete received a character trailer and visual ahead of the January 2023 premiere date for the anime. Grete is voiced by Miku Ito.

Keiichiro Kawaguchi is directing the anime based on a light novel written by Takemachi and illustrated by Tomari, with Shinichi Inozume on the series composition. Sumie Kinoshita is in charge of the character designs.
Yen Press licensed the light novel in English and describes the plot as:
Following a devastating military conflict, countries fight their wars in the shadows. One unusual spy, Klaus, has never failed on the job despite his quirks, and he is building a team to take on an Impossible Mission—one with over a 90 percent chance of failure. However, his chosen members are all washouts with no practical experience. They’ll have to use every trick in the book (and some that aren’t) to prove they’re up to the task!
