In this crossover anime, I fight against the supernatural in my everyday world.

“Boys and girls of this age are all foolish. In addition, given my status as the son of the head of the Metropolitan Police Department’s Criminal Investigation Bureau, with just a little guidance, I can obtain a lot of useful information.”

"I was just using them."

Yoru didn't comment on Light Yagami's actions at all, and went straight to the point.

"The reason I called you here is very simple."

He looked directly into Light Yagami's eyes and spoke softly.

Are you familiar with the "Sunny Doll Killer" incident?

Light Yagami nodded.

"Well, even though I don't have the ability to punish criminals outside of Tokyo at this stage, I do keep an eye on some of the more well-known ones."

Immediately afterwards, Light Yagami frowned slightly, and the smile on his face disappeared.

"Since you've also taken a liking to this case, it means this isn't just an ordinary serial murder case? Is there... a supernatural element involved?"

"Yes."

Yoru nods slightly and tells Light Yagami in detail about the strange traces left by the Teru Teru Bozu killer at the scene, as well as the appearance of a weather maiden in Kyoto City who can change the weather during this period.

He didn't directly say Amano Hina's name, but used the name "Haru-onna" as a substitute, nor did he mention that Hina was one of his assistants.

After introducing the basic situation, Ye Xing picked up his coffee cup, took a sip, and said calmly.

"It's still as bad as ever."

Then, he looked at Light Yagami sitting opposite him, who seemed to be deep in thought, and said with a light laugh.

"This target is rather special. Although he possesses powers that resemble those of an evil spirit, his behavior and thoughts are those of a completely human criminal."

"And compared to me, an exorcist, you are clearly more experienced in dealing with human criminals."

"How's it going? Do you have any ideas?"

Yagami Light pursed his lips, his slender hands overlapping their fingers, and he rested his chin on the back of his hand. After thinking for a long time, he slowly opened his mouth to reply.

"My father once said that to become an excellent criminal investigator, one must put oneself in the criminal's shoes and think from the criminal's perspective during the investigation process."

"Now that I've put myself in the criminal's shoes, I've discovered something very important."

At this point, Light Yagami paused, looked directly into Yosei's eyes, and said, word by word.

“From the perspective of the perpetrator, the human sacrifice he performed was effective.”

Ye Xing nodded slightly, looking as if nothing was amiss.

"Yes."

There's no need to spell it out too clearly; both of them could figure it out.

From the perspective of those in the know, such as Yoruhoshi, Yukino Yukinoshita, Rio Futaba, and Miko Yotsuya, they all know that the reason why the weather in Kyoto City has been clearing up so quickly lately is because of the prayers of the weather goddess, Hina Amano.

But what if we look at it from the perspective of a Teru Teru Bozu (a type of Japanese doll) killer?

Every time it rains, he would cruelly sacrifice a young girl.

Then again?

The weather will clear up.

This is the perspective of the Teru Teru Bozu killer.

In his eyes, the fact that the weather cleared up was proof that his human sacrifice had truly received a divine response.

"but..."

Light Yagami squinted slightly and muttered to himself.

“The coincidence of the weather is not the real reason for him to commit such a crime. Even if an ordinary person has heard of the legend of the Weather Maiden, it is impossible for him to kill someone just because of the unusual weather during this period.”

At this point, Light Yagami looked at Night Star and asked.

Do you have photos of the scene where the five victims were found?

"Have."

Ye Xing took out her phone, opened the photo album, and handed it over.

On the night he infiltrated the Metropolitan Police Department, he naturally collected the crime scene photos that the department possessed.

File transfers leave traces.

Therefore, Ye Xing chose the simplest and most basic method, which is also the most primitive screenshot method.

Take a picture of the screen with your phone.

Upon seeing the photo, Light Yagami did not find it funny or comical. Instead, he gave Yoshinori a deep look, his eyes revealing a hint of admiration.

If it's just photos of the scene taken by the Metropolitan Police Department, it's not actually that hard to get them.

After all, although the investigation process was confidential, even Yukinoshita Haruno was able to obtain a scene photo stored by the Metropolitan Police Department through her family connections.

But the photos taken directly by the phone at the computer screen are completely different.

This means that Night Star once infiltrated the Metropolitan Police Department and escaped unscathed without alerting anyone.

Light Yagami asked himself honestly, and knew that if it were him, he would absolutely not be able to do such a thing.

"Also, the autopsy report."

Yoshiki also showed Yagami Light the autopsy reports on the five deceased that were recorded on his phone.

Looking at the dozens of photos taken from various angles of the deceased's body and the crime scene, as well as the five autopsy reports that were practically identical except for the deceased, Light Yagami fell into deep thought.

"Yexingjun."

Light Yagami pointed to the relevant photos and autopsy report of the first case and spoke with a serious expression.

“In cases like this serial murder, the most important thing to pay attention to is the first crime committed by the killer.”

"Criminal work is also a process that requires continuous practice and improvement."

"The first case will leave the most loopholes and expose a lot of information."

"Especially in serial murder cases with special significance, the specific manner in which the victims died, from a certain perspective, reveals the killer's true inner thoughts."

"What makes this serial murder case special is..."

Light Yagami spoke in a deep voice.

“From the first murder case to the recent fifth murder case, the killer’s modus operandi has remained completely unchanged, which is very abnormal.”

At this point, Light Yagami pondered again, muttering to himself.

"The modus operandi remains unchanged, and the frequency of crimes is fixed on rainy days..."

"There is no doubt that the murderer was mentally unstable."

"Unwavering in their belief in their goals... then what about their attitude towards the so-called 'weather maiden'..."

"A ritual to clear the weather...and not in private, but displayed outside, intended to attract everyone's attention and make their crimes widely known..."

Light Yagami's eyes flickered as his thoughts raced.

After several minutes, he put his hands together, looked directly into Ye Xing's eyes, and slowly began to speak.

"Ye Xingjun, I've pretty much finished the profile of the criminal."

Night Star replied casually.

"Then tell me."

Light Yagami nodded and offered his analysis.

“A mentally unstable person has antisocial tendencies, but not in the usual sense of antisocial personality disorder. Rather, it is an inferiority complex that craves attention and expectation.”

"This inferiority complex, coupled with the abnormal weather during this period and the legendary story of the sacrifice of the Weather Maiden, has given this criminal, who suddenly gained great power for some unknown reason, a sense of destiny."

He believed that as long as he sacrificed enough young girls, the weather in Cherry Blossom Prefecture would return to normal.

"The perpetrators weren't obsessed with the weather; rather, their actions stemmed from their own psychological issues, and they were seeking something significant that could bring meaning and change the world..."

Before Light Yagami could finish speaking, Yosei waved his hand, looking bored.

“I have no interest in knowing the criminal’s thoughts and motives; I just want to know what his next move will be.”

"it is good."

Light Yagami didn't care about Yosei's attitude. After all, his analysis of the criminal's motives and psychology was only to guess the other party's next move.

He had no desire or interest in understanding how a human could become a monster who cruelly murders his own kind.

There is only one end for evil.

They were ruthlessly punished.

Nothing else matters.

"In the eyes of those of us in the know, the act of human sacrifice by the Teru Teru Bozu Killer was completely meaningless; it was merely a coincidence that the True Sun Maiden was praying."

"But from his perspective, the credit for changing the weather through his own sacrifice was stolen by the person who impersonated the Weather Maiden."

At this point, Light Yagami paused for a moment, then changed the subject.

"Of course, there is another possibility."

Night Star understood what he meant and said softly.

"His goal in sacrificing himself was not to clear the weather, but to make the rain continue."

"Yes."

Light Yagami nodded and smiled.

"But as mentioned before, his real goal is not to change the weather, but to become the one who changes the weather, thereby satisfying his twisted desire for attention and expectation."

"Whether he wants the weather to clear up or he wants the rain to continue, that weather girl is his biggest obstacle."

"I can't predict his next move, but to attract the killer's attention and lure him in, all I need to do is this..."

.......

When Ye Xing got home, she had just opened the door and hadn't even had time to change her shoes when she felt something soft and fluffy jump into her arms.

"Big brother~"
