Hikaru Shindo is like any sixth-grader in Japan: a pretty normal school boy with a two-tone head of hair and a penchant for antics. One day, he finds an old bloodstained Go board in his grandfather's attic-- and that's when things get really interesting. Trapped inside the Go board is Fujiwara-no-Sai, the ghost of an ancient Go master who taught the strategically complex board game to the Emperor of Japan many centuries ago.
