Stravaganza - Isai no Hime [Manga]

Humans live mostly behind safe walls, protected from the many non-human creatures outside. IN this kingdom’s walled capital city of Mitera live an unusual young warrior woman known as Claria. The story begins as she takes a potentially deadly walk alone in the woods, encountering various dangerous creatures – most notably a lizardman that treats her surprisingly kindly. But what no one knows about Claria is that she is secretly this kingdom’s ruler, Queen Vivian!
