Sai's Internet Go games have people around the world guessing who he is. Akira, Hikaru's rival, suspects it's Hikaru himself. He even skips the first day of his pro exam for a re-match with "Sai."

When Hikaru convinces go master Toya Meijin to play Sai online, the meijin raises the stakes: if he wins, "sai" must reveal his true identity; if he loses, he will quit the game forever! Then, Hikaru challenges himself by playing Kurata 6 dan. How do you win a game in which both players use the same color stones?!

"The main storyline takes a holiday, making way for six tales that offer fresh insight into the characters and lives of Akira Toya, Tetsuo Kaga, Asumi Nase, Yuki Mitani, Atsushi Kurata and Fujiwara-no-Sai. Hikaru Shindo figures in some of these and takes center stage in the final tale when he challenges a crooked antique shop owner to a game of go in an attempt to restore an heirloom vase to its rightful owner"--Publisher's web site.

Hiraku manages to pass his insei test, but his new opponents are much stronger than he expected and he loses almost all of his games. Will he ever rank high enough to play against Akira Toya?

Hiraku struggles to turn his losing streak at the insei school around in time for the Young Lions Tournament, where he could have a chance to play against his rival, Go prodigy Akira Toya. But that's only three months away!

Hikaru faces the preliminary rounds of the pro test in which he must eliminate all opponents, including one who seems to know how to exploit Hikaru's weaknesses.

"Go players under the age of 18 in Japan, Korea, and China are getting ready to qualify for the Hokuto Cup. Hikaru and Akira are both in contention for the Japanese team, but the preliminaries prove to be tough going. Stung by a reality check, Hikaru focuses like never before. But will it be enough to meet the challenge of the unconventional yet formidable go of Kiyoharu Yashiro of the Kansai Go Association?"--Page 4 of cover.

Hikaru ignores Sai's pleas to let him play Go, and then Sai vanishes! Where has he gone? Will he come back? Can Hiraku play with Sai's coaching?

Hikaru learns his rival, Akira, has landed a place on Japan's team for the Hokuto Cup and battles for one of the two remaining spots, while the Go world is shocked by Akira's father's retirement.
