This was a pretty unique manga, but I definitely see why it ended here. A lot of the time it felt like a vehicle for the author to set up a topic and blab about it later.
In a way, the complete lack of any serious plot kinda made it feel like a children’s history TV show. Like even this one was has the “uhhhh don’t you mean Santa?” bit to setup some history, and a whole moral about spending time with your family at the end lol.
Anyway I still enjoyed it, nice to have an isekai which is just played straight for once. So many authors do zero research on their “”medieval“” settings that it’s quite refreshing to see a counter example like this.
