The tired, worn, eyes of the nigh-ethereal Tadatsuru Teori speak volumes. His existence is one plagued by difficult questions. How much of what we do is by our own design? In his own words, Tadatsuru felt “cast” before Koyomi as an actor, merely playing the role of a villain. Perhaps his origami, then, was not simply a method to pass the time, but instead a method to anchor himself to reality; a way to feel like there was at least one action that he could perform of his own volition. He is alive on the outside, dead on the inside.
The cold visage worn by Yotsugi Ononoki belies the breadth and depth of emotion that she is able to feel, despite her lack of humanity. If Tadatsuru is alive on the outside, but dead on the inside, Yotsgui serves as his foil: dead on the outside, but alive on the inside. It was Tadatsuru’s role, and perhaps even his wish, to be extinguished by Yotsugi. The living and the dead, contrasted side by side, but not so discernably different in the end. Both at the mercy of some higher power, acting as nothing more than mere puppets… or perhaps dolls.
