Hikaru no Go (ヒカルの碁) is an anime and manga series about Hikaru Shindo, an (initially) eleven-year-old Japanese schoolboy, who accidentally releases the ghost of Fujiwara no Sai, a Heian-era Go master who killed himself, and whose spirit was trapped in a bloodstained Go board. Once released, Sai's spirit posesses Hikaru, because he is desperate to play Go again, seeking to achieve the Divine Hand, the perfect decisive move. Initially, Hikaru plays for Sai, instructed by their mental link, simply to get him to shut up.
