Conan and Gin are both my brothers, what's wrong with meeting them once?

Was the bomber Teiji Moriya?

Kogoro Mouri's somewhat irresponsible guess attracted everyone's attention.

Shiratori frowned and said, "But Professor Moriya's house also exploded... He can't possibly blow up his own house too, can he?"

“Indeed…” Professor Agasa scratched his head, “A single symmetry cannot be considered evidence.”

Just as everyone was pondering this, Kudo Kazuma's phone rang.

Conan's eyes lit up: "Is it that person?"

Kazuma Kudo shook his head.

The phone number for Dr. Agasa's house.

Professor Agasa is here, so... it's Ai Haibara?

The call connected, and a girl's clear, cool, and childlike voice came through.

"I heard from the professor that Shinichi Kudo is in the hospital. You're in the hospital too, right? You impersonated Shinichi Kudo and answered the bomber's call, so you're investigating who he is, right? I have some clues here, listen carefully."

Kazuma Kudo raised an eyebrow. How could he forget that besides her medical talent, Ai Haibara's greatest strength was her information gathering and analysis skills?

Can it be played out loud?

Ai Haibara: "...Yes."

A moment later, everyone in the ward heard the girl's clear and logical analysis.

“I first looked into the series of arson cases from a few days ago. The only thing that those houses that caught fire had in common was that they were designed and built by the architect Teiji Moriya, and were his early works. The same is true for the Beika Municipal Building.”

"Based on this condition, I compared the explosion locations reported in the news. Four of the bombs on the circular line were symmetrical, and the only one that was not symmetrical was at the Sumida Canal Bridge—which also happened to be Professor Moriya's work."

Shiratori pondered, "So, the bomber must be someone who has a grudge against both Professor Moriya and Shinichi Kudo?"

Ai Haibara didn't respond to that, but continued, "Besides that, there were other discoveries."

“We also found a commonality between the Tsukawa Green Park and the Beika Station Plaza – they are built by the same contractor, which is also responsible for the Beika Municipal Building.”

"And three of the residential areas where the explosions occurred were homes of high-ranking employees of this company—that's how it is."

Seeing Conan quickly draw several circles on the map, Kudo Kazuma replied to Ai Haibara on the other end of the phone, "Thank you so much for your help."

"The rest is up to you."

Ai Haibara spoke, her tone carrying a hint of warning.

"And you two, you didn't eat lunch."

Kazuma Kudo: "No, it was an emergency..."

Did this girl hang up the phone?

Xiaolan immediately stood up: "I'll go check the hospital cafeteria; they should still have food."

Ayumi, whose eyes had been sparkling, looked up at Kudo Kazuma and asked excitedly, "Kazuma-nii, was that Ai-chan who just called?"

Seeing Kudo Kazuma nod, her eyes lit up even more: "Wow! She's so cool!"

Genta nodded emphatically, particularly proud: "As expected of a detective from our Junior Detective Club!"

Only Mitsuhiko seemed thoughtful: "Based on the clues provided by Haibara-san, is it possible to find where the other two bombs are hidden?"

“That’s right.” Conan turned to Shiratori and said, “Officer Shiratori, if you check the higher-ups at the company that Haibara mentioned, you’ll probably find out where the other two bombs are.”

After Shiratori left, Kogoro Mouri scratched his head and said, "So, it seems that the bomber must be Teiji Moriya, right?"

He counted on his fingers and said, "That morbid obsession with symmetry, he only puts symmetrical bombs on symmetrical works and blows up asymmetrical ones, which seems quite reasonable."

Mitsuhiko scratched his head and asked, "Then why did he blow up his own house?"

Kazuma Kudo shrugged: "Maybe his house isn't symmetrical enough?"

His words left everyone speechless.

He simply shrugged.

The designs by Teiji Moriya are indeed quite symmetrical.

However, the interior decoration and room layout are completely asymmetrical, which shows that the guy's obsessive-compulsive disorder is not enough.

Besides, the Moriya residence was blown up by Moriya Teiji himself. He saw it with his own eyes, so how could it be fake?

A short while later, Ran brought back two meals according to Conan's taste.

After the meal, Kudo Kazuma left, citing feeling unwell.

Most people present knew he was in poor health, and a few knew that he and Conan were not suited for prolonged close contact, so his departure was perfectly logical, and no one felt anything was wrong.

After leaving the hospital, he chose a direction opposite to that of the Yin clone and drove to the area of ​​the explosion.

Today's various big explosions really left him with a lot of spirit, which can be considered a rather generous birthday gift, right?

After Kudo Kazuma absorbed the spiritual energy from the various explosion points and recalled his Yin clone, it was already past six in the evening—another wave of spiritual energy was due to arrive at eight in the afternoon, so he decided to find a place to eat something first.

Then he received a call from Professor Agasa's house.

It can't be Ai Haibara again, can it?

Kazuma Kudo answered the phone, and Conan's voice came through.

"Mom and Dad sent birthday presents, do you want to come and open them together?"

Kazuma Kudo: "...Okay."

Anyway, the final explosion won't happen until 8 o'clock, so what's the harm in eating somewhere else now?

Upon arriving at Agasa's residence, Kudo Kazuma asked a few simple questions and learned that Mouri Kogoro had told Inspector Megure that Moriya Teiji was the bomber.

Conan also found evidence that the bomber was Teiji Moriya, and used Kazuma Kudo's identity to call Inspector Megure.

The two bombs that were planted in the residential area but did not explode have also been found.

Based on the extent of the explosions, the police deduced that the amount of explosives used in these explosions was roughly the same as the amount stolen from the Japanese gunpowder depot. In addition, since Teiji Moriya had already died in the explosion at the Moriya residence, the bombing case was closed as a suicide.

Although the case is closed, the Metropolitan Police Department still has a lot to do, but that's not something they can worry about.

Conan took out a small, already opened box and placed it on the coffee table. Inside the box were two gift boxes, each slightly larger than the palm of his hand. One box had "Shinichi" written on it, and the other had "Ichima" written on it, indicating that they had already been distributed to them.

The two brothers exchanged a glance, and just as they were about to each take their own gifts, the phone rang at Professor Agasa's house.

After Dr. Agasa answered the phone, he immediately put it on speakerphone.

"Shinichi, Kazuma, it's Yukiko on the phone."

Then, Yukiko Kudo's cheerful voice came through the phone: "Shin-chan~ Shin-chan~ Did you miss me? Your birthday presents should have arrived by now, right?"

"Hello, hello." Conan couldn't help but glare at her. "It should be the middle of the night in America right now, right? What made you think of calling now?"

"Who told you I was in America? Yusaku and I are traveling in Europe right now~" Yukiko Kudo's voice was eager. "Come on, open the gifts and tell me if you like them."

The two brothers exchanged a glance and, without prior arrangement, took out their gifts and began to unwrap them.

After opening them, both of them were stunned.

Kudo Kazuma asked in confusion, "What does this mean?"

Conan was speechless: "What does this mean?"

"It seems you quite like it." Yukiko Kudo on the other end of the phone expressed her satisfaction.

Kazuma Kudo nodded: "It's alright."

Conan: "...Damn it!"
