He played with much enthusiasm and was content, until he one day when he was confronted by another of the emperor's tutors. During a match to determine who would remain as the only teacher in the palace, Sai's rival cheated, causing his defeat. Sai became so distraught by the removal from his position that he committed suicide. However, because his soul became restless, he was unable to leave the physical world and became bound to a go board, called a goban.

One day, he stumbles upon an antique goban in his grandfather's attic and unlocks the spirit living inside. He is forced to provide a space in his mind for Sai to live. They coexist together, and to appease his new comrade, Hikaru begins to participate in games of go...

This marks the beginning of Hikaru's rise to fame in the world of go.
