The ad led me here, but boy oh boy do I want to stay here forever. Only looked into the first couple chapters, but I see this as "Hakumei to Mikochi" in a more adventurous setting, basically. Author's attention to detail in a manga focused on world-building is very appropriate, too. First impression is so satisfying. Will rate when I finished up to the current chapter, but I suspect this will get 9-10/10 from me.
