These aren't heroes training for battle. They're regional guardian spirits learning to care for a single prefecture, and the show treats that ordinary responsibility like it matters. Each episode finds comedy and warmth in the smallest acts of stewardship: a junior Dochamon figuring out how to protect their assigned corner of Japan, often failing, always trying. The entire series is built around the idea that being a good guardian means showing up for people nobody's watching, in places nobody's famous for. It's the anti-spectacle: no world-ending stakes, no tournaments, just spirits learning that the job is just to be present. Watch this when you need proof that small work done with care is its own kind of heroism.
Japan's 47 prefectures each have a guardian spirit, known as a Dochamon, watching over them, but those spirits will one day need successors. The juniors are guardian spirits in training, preparing to eventually take over the duties of their elders. There is just one problem: these youngsters still have plenty of maturing to do before they are ready to graduate. The episodes are short and played for comedy.
