"Hikaru no Go" just means "Hikaru's Go". Hikaru first arrived on the scene in December 1998. He made his first appearance in the weekly Jump comic for Japanese children. Soon he had his first book. Here is the cover:
Within a year he had 3 books out. Soon there was more than a dozen. Now there are 23 (plus a character guide). Hikaru became really popular when his animated series started. It was shown on Japanese television during the evening. It was watched by many children. They then all wanted to play Go like Hikaru.
Hikaru finds an old Go game board in the attic. Only he can see stains of blood on it. He rubs the spots and the spirit of Sai appears to him. Sai was a Go Master many hundreds of years ago. He died in shame and his spirit stayed trapped on the Go board. He can only escape by leading Hikaru to become a Go master too. Hikaru's adventures start when he is shown by Sai how to place the stones to beat child star Akira.
