1x9 - Akagi

At the Kawada group's headquarters, the fake Akagi (Yukio Hirayama) and the genuine Akagi face off to demonstrate their skills. Akagi insults the impersonator, because of his reliance on his mathematical skills and excellent memory, and shows him just how frightful his talents are. Following this he then returns to his workplace to find his senpais swindling Osamu in a game of Mahjong.
