Isumi, Waya and Hikaru decides to go to a recommeded Go Salon and Hikaru bumps into a rude young boy at the convenience store. Sai advises Hikaru not to pursue the incident as he senses that the young boy had some issues with himself. Upon entering the salon, the trio realised that it's a Korean Go salon (Koreans are known for their strength/domination in the Go world)and that the rude young boy is the owner's nephew called Su Young - a Korean insei-equivalent. Back at the institute, the editorial team was discussing Japan's poor performance in the world stage and Korea/China's domination. When Hikaru challenges Su-Young to a match, it turns into a Korean Vs Japan fight-out. The owner recounts Su-Young's history to Isumi. Su-young has been a very promising young talent who rose quickly through the ranks but a losing streak demoralises him to the extent of almost quitting Go and his parents sent him on a holiday to Japan. As the game starts, Hikaru vows to win and let Su-Young remember (thetvdb.com)
