Yuuki Yuuna wa Yuusha de Aru: Washio Sumi no Shou

In the 298th year of the god's era, three elementary schoolgirls—Sumi Washio, Sonoko Nogi, and Gin Minowa—are given a critical mission. They must take on the role of heroes to confront Vertex, an enigmatic force threatening Shinju-sama, the divine tree safeguarding Shikoku, the last livable region on Earth. The girls are unaware that their involvement in this battle will demand a greater sacrifice than they can foresee. This manga is the second adaptation following the discontinuation of the first.
