in order to adapt to the defense mechanisms of people’s thoughts in society, I imagined a body being able to predict the attacks from an unknown threat, and having a mode that can respond these attacks specifically. When two experts of martial art are fighting each other, there is an especially physical reaction called “Musha Furui.” The appearance of this reaction indicates that a fighter who, perceiving the comparable power of the opponent, the body and spirit of the fighter will start trembling with excitement. In my performance, the trembles went beyond the limit. It seemed like a body overloaded with experience, would end up ruining itself.
