written by Yumi Hotta and illustrated by Takeshi Obata is a manga series based on the ancient board game Go. When Hikaru Shindo discovers an old, bloodstained Go board in his grandfather’s shed, the 6th grader knows things are about to get weird. His discovery unleashes the ghost of Fujiwara-no-Sai, an ancient Go master from thousands of years ago who has been trapped in the board for centuries. Because Hikaru is the only person who can perceive Sai, Sai joins his consciousness as a distinct entity and together, they become a formidable team. Can they achieve Sai’s long-held goal of achieving a “divine move?”  (Juvenile Graphic Novels and Manga
