Looking back at the struggle between Koharu and Shu Tianyao in The Home of Seven Stars in Jingbo Lake, we can see that Koharu's way of thinking is different from ordinary people. At that time, Matsuoka was stabbed by a knife dozens of miles away, and rescue troops were coming. Koharu and Matsuoka have self-defense weapons, so we have to delay to capture them alive.
However, Koharu understood that the purpose of Tian Yao's escape was to protect Jingbo, so he deliberately took Jingbo as a hostage and forced Tian Bo to appear. In the battle with Tian Bo, he deliberately missed him, just to get close to Tian Bo, and he could take his own life. They were so close, but Koharu missed it, and even a gun went through his head, which showed that she did it on purpose.
Koharu's purpose is very clear. She wants to collect prisoners' thought particles. She understands that particles in several fields are easy to get, as long as he shows his murder to himself, but the murder of Jingbo Qixing needs to borrow her feelings for several fields, so she will use the characteristics of murder and love confusion to let several fields die in front of her and have the opportunity to release love to herself. After seeing this, she will have murder.
After the formation of Jingxing Seven Stars Well, Sakai households entered the investigation. This time, Jia committed suicide, not to find out the murderer, but to expose the hidden story behind the grave digger incident. The world in the well is a circulating train. This car once killed Jingbo's mother, but Jingbo was subconsciously trapped in the car forever. At the same time, there are several other places in the car, which sit very close, but there is no intersection. In this world, John E. Walker also appeared. It was his guidance that distorted the thinking of Jingbo Qixing and became a prisoner.
When Jingbo Qixing was interrogated, a BGM song was put in the animation, and the lyrics corresponded to her heart. I'll translate it for you, and it should be clear. The lyrics are: this love has no final ending. I can only look at you and reflect your face in the window. We don't even know what went wrong. No one can stop the train. The world is so beautiful, but it tears my heart forever.
The seven-star story of Jingbo Lake and several other places just confirms a sentence: poor people must have something hateful. Jingbo was unlucky. As a result, John E. Walker found an opportunity and trained him as a serial criminal. Ji Tianyao also had an intersection with John E. Walker, and became a puppet of love after opening a hole. Therefore, John E. Walker is behind the scenes. He is likely to use the loopholes in the system to enter the subconscious. At the same time, he found a camera in the prisoner's house. Actually, it's John
Finally, talk about Koharu in this town. This role must be qualified as a detective. The condition for entering the well is murder and recidivism. Singing gourd ladle and opening holes all meet the requirements, so why does Koharu meet the requirements? On the bright side, Koharu only killed a few Tian Yao, but in fact, her behavior of drilling a drill before opening the hole can also be counted as homicide.
At the same time, Koharu's personality is very distorted, and she will be excited by murder. As Matsuoka said, Koharu acted alone for many times, looking for vicious criminals to fight one-on-one, not out of a sense of justice, but because she felt happy from it, which is actually the psychological state of most serial criminals.
