Eight years after witnessing her parents' death, Shion qualifies herself as a professional shogi player. However, her precocious career starts to draw unwanted attention.
Shion is saved in the nick of time from a dangerous stalker. However, her drama continues as she receives a threatening letter before an important match.
A little relief comes to Shion when the man who attacked her six months before is finally arrested. She also recognizes Ayumi as the boy who saved her at that time.
Shion has another fiery match against Ayumi, while the police discovers that the man who killed her parents started to move again.
Shion is hospitalized after having a glimpse of the night when she lost her parents. Meanwhile, Nikaido and Ayumi have their first duel.
After Shion recovers, she goes on a trip with her family. Upon returning, she and Nikaido receive a sudden request from Hani-Meijin's younger brother, Satoru.
Shion and Nikaido have their first match as a demonstration of their abilities to Satoru, who wants to create an all new, unrestricted shogi tournament.
Shion visits Ayumi's mother at the hospital, and later, she and Ayumi start to make plans for the upcoming tournament.
Nikaido has a tough match in the tournament against Kamizono who also happens to be Ayumi's master. Kamizono however, is not at the best of his health.
Shion's next opponent is a young prodigy who polished his skills in online matches, and learned from an anonymous source a way to leave her mind unstable.
Shion received a threatening call from the murderer, and Hisatani gets himself in trouble when the police finds out that it was made from his cell phone.
Shion, Ayumi and Nikaido prepare themselves as each one has a strong enemy to face in order to gain a place in the finals.
During Shion's match with Satoru, she starts to get a glimpse of his hostility towards her.
Nikaido discovers Ayumi's secret, but decides to not expose him. Later the tournament's remaining contestants decide their opponents in the finals.
Shion's first opponent in the finals is none other than her foster father. During the long match, she eagerly looks for a way to defeat him, while he reminisces about the time when she became his apprentice.
Ayumi is devastated with the death of his mother, and looks for a reason to continue playing shogi before his match with Satoru.
Shion's got a chance to play against Satoru once more in the tournament's semi-finals, but during the match, he questions her about the night her parents were murdered, which brings up some memories she had long forgotten.
Shion and Satoru's match continues, while Hani-Meijin introduces Ayumi as his disciple.
Satoru and Ayumi meet up and from the evidence figure out who the murderer is but are unsure of motive. In the mean time, the police are looking up Satoru after what he said to Shion after their match.
Shion starts remembering more things about the murder incident. Hani-Meijin and Shion play where they had left off 8 years ago.
Purposely goaded by Hani-Meijin, Shion fully remembers the incident. Meanwhile new evidence is found.
The evidence is conclusive, Hani-Meijin is the killer of Shion's parent's and his younger brother's girlfriend. Despite this, the match goes on. Hani-Meijin confesses that he killed Shion's parents to raise up a competitor that would be strong enough to take him to new heights and claiming he "raised her", but to do so, he must win the match. However, Shion wins with a perfect defense. She regains her voice to tell Hani-Meijin that she is not a product of him, but her family and friends. Hani-Meijin is arrested and Shion is promoted to a 4-dan professional kishi. Ayumi is shown winning a match and also becoming a professional kishi. Nikaido announces her intentions to become one as well. The final scene shows Shion in a match as a 5-dan and having retained her voice.
