Yuki Yuna is a Hero Season 1 Episode 12

Smile At You

Yuna is forced to fight against Mimori, who can't bear to lose her memories of everyone like she did with Sonoko, or be forgotten about herself. However, Yuna states her determined feelings to never forget about Mimori and manages to stop her. With the Vertex's final attack headed for Shinju, all of the girls, despite the afflictions caused by their Mankai forms, band together to block the attack, with Yuna delivering the final blow just in time, after which their fairies disappear, ending their role as heroes. After the battle, each of the girls start to slowly recover what they have lost, including Mimori's use of her legs and Itsuki's voice, but Yuna has remained in a coma-like state as a result of her efforts. Visiting her every day, Mimori feels overcome with guilt over what happened, but her voice soon reaches Yuna, who awakens once again. Finally able to perform their long-awaited hero play, Yuna feels confident that she can accomplish anything with her fellow heroes by her side.
