The production team for The Seven Knights of the Marronnier Kingdom has revealed three additional voice actors for the fantasy series. Natsuki Hanae will voice Justice, a knight of the Marronnier Kingdom who is also Hugo's nephew. Joining him are Mitsuki Saiga, who takes on the role of Justice's adjutant, Zoe, and Miyuri Shimabukuro, who plays Colette, the daughter of the kingdom's head chef.

These actors join a project currently in the midst of its broadcast run, which kicked off on NHK Educational on October 3. The anime is being produced by J.C. Staff under the direction of Kiyoko Sayama, with Shinzō Fujita overseeing the series scripts. The story follows seven brothers, each serving as an ambassador to a different kingdom in a quest to find their fated partners.

For international viewers, the series is available on Amazon Prime Video, which also offers an English dub. The underlying manga by Nao Iwamoto has been a staple in Shogakukan's Flowers magazine since 2016, and Viz Media recently expanded accessibility by launching a digital release of the source material earlier this month.
