Yuuki Yuuna Is a Hero - Season 1 Episode 10 Bonds of Love

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 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. Investigating a hidden barrier facing opposite the Shinju, Mimori goes inside to discover a hellish landscape 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 blasts a hole in the barrier, unleashing several smaller Vertexes into the forest.
