Shukichi and the group confront the culprit, Tanimori, at the hotel Masumi is staying. Tanimori once obsessed in winning a Shogi match against Shukichi in order to make his wife, who was terminally ill, proud. However, in his zeal to win he made a mistake which cost him his victory, and Shukichi, knowing about his emotional distress, tried to persuade him to go visit his wife before she died. Misunderstanding the intention behind it, Tanimori became obsessed with beating Shukichi in a replay of that fateful match, kidnapping Yumi both to test his opponent's deductive skills and to face him alone. However, Shukichi proves that Tanimori would have lost even in a fair match, and Tanimori surrenders to the police.
Upon awakening from her drug-induced sleep in which Tanimori had kept her, and learning about her liberation by his hands, Yumi and Miike hurriedly escort Shukichi back to the conclusion of his match, and Yumi kisses Shukichi as a good luck charm, although she remains blissfully ignorant of both his true profession and the nature of the match. He returns to Yamanashi in time to win his 7th Shogi title. Strangely, this victory also garners the undivided attention of both the Unknown child and Subaru Okiya.
