The Yorozuya are stunned to see Yamazaki's completely altered appearance and competence. The other Shinsengumi members celebrate his victory over the tank that not even Hijikata and Okita can beat and Gintoki wonders how Yamazaki transformed into a cornerstone of the group. He explains that realizing his weaknesses, he tried to become stronger by copying what Kondou was doing, training with weights. He couldn't handle it so abandoned the training. While thinking, he realized that his body was its own weight, its own fetter so he was able to throw off the fetter called Yamazaki Saguru and become a new person, the muscular hero named Zakiyama. In emphasis, the Yorozuya and the Shinsengumi sees the original Yamazaki soul coming out of Zakiyama as a tail.
