Anime broadcast: what has been confirmed

The Crunchyroll News article alone does not constitute a rights announcement for France. Before choosing a service, viewers will need to wait for official communication about legal availability and French subtitles. The news section will track these confirmations.
Nao Iwamoto’s manga has been published in Shogakukan’s Monthly Flowers since 2016. The anime therefore has an established world built around eight kingdoms.
A family adventure driven by travel
The trailer contrasts the seven brothers through their temperaments and nicknames. This setup feels more like a chronicle of a family and several kingdoms than a series focused on a single hero. The footage also emphasizes travel and encounters. It is not yet enough to describe the season’s full structure.
For viewers, the concrete reference point is the Japanese date of October 3, 2026. In France, watching the series will still depend on a legal platform. The cast already makes it possible to identify the seven brothers, Baribara and the narrator in future videos.
