Yuki Yuna is a Hero: The Washio Sumi Chapter

Chosen by the divine Shinju-sama, Sumi Washio, Sonoko Nogi, and Gin Minowa are appointed as heroes tasked with protecting the world from the destructive Vertexes. While they wait for the moment they’ll be needed, their days pass quietly—until a Vertex appears without warning.

Caught unprepared and lacking coordination as magical girls, the trio is pushed to the brink before scraping out a victory through sheer resolve. Shaken by how close they came to defeat, they commit to strengthening their teamwork and sharpening their fighting skills. Yet as the Vertexes continue to emerge and demand greater power to overcome, the toll of relying on that magic begins to surface—forcing the girls to confront what they may have to sacrifice to keep humanity safe.
