|“|| The story takes place on the Japanese island Shikoku in the God Era. 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 a 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.
