Mimori recalls the events following the loss of her memories, including her first meeting with Yuna and how they came to join the Hero Club. Having discovered her legs and memory were lost because of the Mankai form when she was hero before and that everything from her standard of living to moving near Yuna was arranged by Taisha, Mimori once again approaches Sonoko, who tells her the true nature of the world: One day the gods had decided to end and cleanse the world, sending the Vertexes, but some gods tried to save mankind and merged to form Shinju and raised a barrier around Shikoku to preserve it. Mimori flies to the barrier and crosses it to discover a hellish landscape outside filled with smaller Vertexes that are rebuilding the ones that were already defeated, dooming the heroes to continue battling until they become completely disabled. Not wanting the others to suffer like Sonoko did, Mimori believes the only solution is to destroy Shinju, and thereby what is left of the world, and blasts a hole in the barrier, unleashing countless smaller Vertexes into the forest.
