Himeno's indecisiveness causes Fenrir to injure her knights, especially Sasame, and this guilt weighs heavily on her. Himeno encounters Mawata, and the two connect in a very endearing way, like true sisters. Both carry heavy burdens and have no one to share them with, or so Mawata thought. In this episode, Himeno manages to find the motivation to fight again, and although the journey was long, that's precisely why this episode is so good. You can't overcome fear overnight.
