"The unparalleled Echizen Ryoma, the perfect Tezuka Kunimitsu, the sacred Fuji Syusuke, and the black dragon Sanada Genichiro who awakened in their first year of junior high, aren't they all world-class players?" "The world shouldn't underestimate our junior high students!" "Professional players would just be watching from the sidelines in our junior high world!"
