Yuki Yuna is a Hero

Plot

The story takes place on the Japanese island Shikoku in the fictional city of Sanshu, based on the real-life city of Kan'onji in Kagawa Prefecture, in the 300th year of the Era of the Gods (神世紀, Shinseiki). Yūna, Mimori, Fū, and Itsuki are all members of the Sanshu Middle School Hero Club (讃州中学勇者部, Sanshū Chūgaku Yūsha-bu), dedicating themselves to helping those that request help. One day in their regular daily lives, the Hero Club members are suddenly caught in an explosion of light and transported to a strange forest, where they encounter mysterious monsters known as Vertex which seek to destroy the Shinju (神樹, "Divine Tree"), the guardian deity which protects and blesses humanity. Using a special phone application granted by Taisha, an organization dedicated to the Shinju, Yuna and her friends must transform into "heroes" with magical powers to protect their world from imminent destruction.
