Later, only at the end of the second episode of animation appeared a scene in which a person came out of a vending machine and asked that charming women to collect coins, and said that as long as he collected coins, he could realize any of her wishes. This also makes people wonder whether Kaga Gu Xiuyi can become a doll monster because of this woman.
So according to the plot of the cartoon, it is really because of this woman that the man can transform. This woman's name is Aoki Jiang, and she is the sister of Aoki Hiroyuki, the animation heroine. Aoki Hiroyuki once witnessed her sister Aoki Jiang turn into a monster in front of her and kill her parents. Later, Aoki Hiroyuki always wanted to find her sister Aoki Jiang Ailin and asked her why she wanted to kill her parents and turn Kaga Gu Xiuyi into a doll monster.
I'm going to use the plot of the cartoon to explain why, so there may be some spoilers. In the cartoon, Jiang Lai Aoki was originally prepared to enter the body of Guxiuyi in Kaga after turning Guxiuyi in Kaga into a doll monster, but it was the first time that Guxiuyi in Kaga met his sister Aoki Hiroyuki, and the right of Aoki Jiang Lai to drill into Dani in Kaga to repair a body was also taken away by Aoki Hiroyuki. So why did Aoki River enter the ancient body of Kaga? This is because she wants to take down a person. Later, after Aoki Jiang deleted her memory from Kaga Guxiu No.1 Middle School, she remembered that there was a shadow who loved him very much, but he didn't know who that shadow was. Therefore, it was very tearful to see this mime in the back.
