Overview: After finishing the third station of the Ryuo War, Yaichi is impatient because he can't even reward his masters. I can't afford to think about the fact that I fell down with a fever. He refused even Ginko's best advice. Every day I'm lonely, staying in my room and immersing myself in my research. Hoping for Yaichi's revival, Katsura leaves a note asking him to watch his game. The next Mynavi main race is a big chance for Katsura to become a female shogi player. What does she want to tell Yaichi through the game?
