Yuki’s journey of self-discovery is triggered by a fire festival that the adventurers witness one night in the forest. She is moved by the spirit of the dancing crowd, the magic of the firelight, and especially the Buddhist hymn to transience: “Life is just a dream.” Later in the film, bound to a pole, she chants these words to her captor, who is moved enough to let her and her companions go.
