くノ一ツバキの胸の内

In a hidden village where contact with men is strictly forbidden, Tsubaki, the top student of the Akane Class, leads a life dedicated to training and duty. But beneath her disciplined exterior lies a secret curiosity about the outside world—especially about boys, a topic she's never encountered firsthand. Alongside her lively and diverse group of fellow kunoichi, Tsubaki navigates the challenges of adolescence, friendship, and the clash between tradition and personal desires. (Summary by Grok 2)
