Everyone knows that France gave birth to the sport of tennis with Camus, the United States created a climax with Reinhardt, and Germany changed the world tennis landscape with Polk, but little did they know that Japan, a tennis desert, also has such a young boy... They challenged the throne; They achieve dynasty hegemony; They are - a dreamy era of miracles! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
