I had been playing the guitar and singing at teens in a rock band. Before that, my father wanted me to become a professional of GO (traditional board game in Japan) player with his enthusiasm. The rock music functioned as the self-formation to leave my parent but musical talent leaves behind me unfortunately, because every my friends said your body action is interesting than music... I thought it was possible to be dance if a rule such as the GO would be rearranged in time and space. It is totally like the music using the body.
