結城友奈は勇者である その後の園子

Sonoko Nogi fought the Vertex as a Hero in year 298, next to Sumi Washio and Gin Minowa, and the power that made those battles winnable took its price from the girls who used it. This light novel chapter is an after-story to the television series, picking Sonoko up once the fighting is behind her and the Shinju still stands over Shikoku. Yuna Yuki's Hero Club stays offstage; the chapter belongs to Sonoko.
