"Do you know anything else about Brother Mizutani and Sister Nanako, Brother Sawamura?" Qian Yu asked. "The more detailed, the better."

"Hmm......" Sawamura said after a moment's thought. Because Mizutani's family background is not good, it seems that the two of them are not supported by Miss Moto's parents for being together, so they eloped here to avoid the eyes and ears of their family - if I remember correctly, they should have come from Chiba's side. ”

Just two years ago, they went to Kyoto together for Tanabata and happened to stay at the hotel called Vega. On the day of the fire, he happened to be alone to see his friends who lived in Kyoto. Speaking of this, Sawamura sighed. After taking care of Miss Hongami's funeral, Mizutani once asked me to go for a drink together, and when he got drunk, he grabbed my clothes and cried there, saying that if he hadn't gone to see his friends, Miss Honjo wouldn't have died. ”

"......" Qian Yu raised his eyebrows when he heard this. That, let me ask, does Brother Mizutani belong to the sensual faction? ”

"Mizutani?" Sawamura thought for a moment before nodding. "He must be a sensual, and Miss Ben also liked his heart when she interacted with him."

"......" Qian Yu nodded, and then asked. That,Does Miss Benjo have any hobbies? In particular, Brother Mizutani also has aspects to dabble in. Or do you know where the two of them confessed? Is it here in Tokyo? ”

"I don't know," Sawamura shook his head. As a hobby, both of them are enthusiasts of astronomical observation, and they also met at a party held by a local association of astronomical observation enthusiasts in Chiba. Their confession seems to have been made at a comet observation event (Comet Clarke) organized by the association in '89, and it is said that Mizutani seems to have specially prepared a comet-shaped pendant for Miss Honjo. So they should have known each other in Chiba. ”

"I see," Qian Yu nodded. "Thank you very much for this information, I left you my phone number, please call me if you still remember anything."

…………

Chiba sat on the tram home, playing with the traceless umbrella in her hand.

He had basically figured out the general situation of the matter, from the cause of it all to the identity and place of the last deceased.

First of all, the murderer of all this should be Kosuke Mizutani - as an emotional person, he is easy to take risks when he is too emotional, and his act of hanging the door number with Nanako and his name on the door back a month ago should be equivalent to a switch for him to turn on his revenge action - he originally avoided the past and wanted to avenge Nanako Motojo, so he hoped to use this door card with traces of Nanako Motogami to clarify his own action intentions. As for how he found the addresses of these people - Kosuke Mizutani had left a year ago and only returned a month ago, so Chiba has every reason to believe that Kosuke Mizutani spent these 11 months conducting a sufficiently sufficient investigation to finally confirm the addresses of all of them, laying the most solid foundation for this series of killings.

Then, there is the identity and location of the next deceased - there is no doubt that the deceased is Kosuke Mizutani himself, and the place of death is supposed to be on Tokyo Tower near Shiba Park.

First of all, there are a total of eight circles on the seven pie tiles and one cake, and there were only eight people on the sixth floor at that time, and seven of the people who have been killed are all who survived, because the eighth person on the sixth floor is Nanako Motogami herself. Therefore, the last case must correspond to Nanako Motogami's position in the elevator at that time - after all, Shuhei Jinno, who pulled Nanako Motogami out of the elevator, already corresponds to a cake, so no matter who is going to kill in the last case, it must be to correspond to Nanako Motogami who has died.

So, the question is, who will Kosuke Mizutani think is most qualified to die on behalf of Nanako Motogami? If it is said that Nanako Motogami is going to die on behalf of him, it means that Kosuke Mizutani must think that this person is most related to Nanako Motogami's death - even Shuhei Jino, who pulled Nanako Motogami out of the elevator and directly caused Nanako Motogami's death, only got a piece of cake that represented him standing outside the elevator at the beginning, so whose priority of responsibility is qualified to be ranked before Shuhei Jino, and is defined in Nanako Motogami's position?

With a sensual personality like Kosuke Mizutani, there can only be one answer - himself.

It was he who didn't bring Nanako Honjo to hang out with, which caused her to be in the hotel at the time of the fire; It was he who left Nanako Honjo alone to meet his old friend, causing him to stay alone in the hotel when the fire broke out, and was eventually dragged off the elevator by Shuhei Jinno with brute force. As Nanako Motogami's boyfriend, referring to Kosuke Mizutani's performance after Nanako Motogami's death, it can be confirmed that Kosuke Mizutani must be very remorseful about Nanako Motogami's death.

In addition to the seven people who robbed Nanako of Motojo's life, he himself is equally to blame, which is why Kosuke Mizutani wants to kill himself at the end - he can't tolerate the crimes he committed, even if he just happens to be not in a certain place at a certain time.

As for the reason why the location is Tokyo Tower, there will be a Tanabata festival in Tokyo Tower tonight, and it will also be the place with the most Tanabata atmosphere near Shiba Park - for a person who is planning to commit suicide, there is no need to deliberately choose an unobtrusive place like throwing a corpse, take out a glass of poisoned wine and drink it all by yourself. Therefore, he will definitely choose a place that can symbolize the Tanabata night full of tears and regret two years ago.

On the other hand, there is an observatory at the top of Tokyo Tower, with telescopes for viewing astronomical scenery, making it a place where to call astronomical observation a place of home.

Meet because of the stars; Acquaintance because of the stars; know each other because of the stars; Stay together because of the stars; Because of Vega, she said goodbye to the yang world, and then reunited with the North Star and the Big Dipper on the side of the Sansheng Terrace. This is probably the most sacred result for Kosuke Mizutani, isn't it?

At the same time, another person was invited into the house by Sawamura Jun.

"Are you here to ask that question too?" Looking at the little boy in front of him, Sawamura said with a smile. "A kid just came and asked the same question."

"Do you mean a kid about my age with a backpack and long black sleeves?" Conan asked.

"You know him?" Sawamura Jun asked curiously. "You're his friend?"

"Know him," Conan replied with a smile. "Of course I know him."
