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 to each of these attacks. When two martial arts experts are fighting each other, there is a strong physical reaction called "Musha Furui". The appearance of this reaction indicates that a fighter’s body and spirit, perceiving and anticipating the comparable power of the opponent, will start trembling with excitement. In my performance, the trembling went beyond the limit. It seemed like a body, overloaded with experience, would destroy itself.
