People in Detective Conan are going crazy over the comments section.

"Hey! We didn't bring a tent!" Inside the scenic area, the Junior Detective League exclaimed in disbelief as they looked at Professor Agasa, who was already drenched in sweat.

Indeed, after arriving at the scenic area, everyone prepared to set up tents, but after Professor Agasa had been groping around in the back of the car for a long time, everyone began to feel that something was wrong.

As expected, after some questioning from Conan, Professor Agasa finally admitted it.

Ultimately, because they hadn't brought a tent, the group had no choice but to drive back...

"Now my precious holiday is ruined," Asakawa Yu complained as she drove.

"Alright, alright, Doctor is just getting old and his memory isn't what it used to be. How about this, when we get back I'll make you all some desserts, okay?"

Seeing Asakawa Yu's resentful look, Miyano Akemi in the passenger seat helplessly tried to comfort him, making it seem like a mother was comforting a child who was upset because the trip was canceled!

"...Never mind, I'm not that petty. I'm just a little tired of driving all day during my rare holiday."

"Hmm? Look, it seems the professor and the others have changed direction and are heading that way," Miyano Akemi pointed out during the conversation, noticing that Professor Agasa had deviated from his original course.

"Hmm...maybe they know some shortcut. They shouldn't be lost...right?" Asakawa Yu said, but he himself didn't seem very confident in his own words...

Finally, as expected, Professor Agasa never disappointed them.

"So, Professor, you don't know where this is either, right?" Asakawa Yu said to Professor Agasa, who was still sitting in the car, as the car was parked on the side of the road.

"Uh... I don't want to spend the night here!"

“That’s right. If the doctor hadn’t forgotten to bring a tent, we wouldn’t be in this situation.”

"That's right, that's right!" The three kids in the car started their verbal attack!

"Isn't it all because of your constant nagging?!" Professor Agasa finally couldn't hold back any longer and retorted.

"Hey Yu, do you know if there are any hotels or anything like that around here..." Helpless, Professor Agasa turned to Asakawa Yu for help.

"Um... I don't know either." Asakawa Yu said that she had no idea how to answer this.

"I think there must be some hotel around here." Seeing that something was wrong, Mitsuhiko quickly reassured him.

“That’s right, that’s right, there might even be a castle with a view of the lake.” Ayumi chimed in immediately.

"How could that be?" Seeing the topic getting increasingly out of control, Conan couldn't help but speak up.

"Really? It's not impossible." Ai interrupted Conan with a laugh.

"Hmm?" Conan asked, puzzled.

Seeing this, Ai Haibara gestured forward, and everyone, including Yu Asakawa, turned their heads.

To our surprise, we actually found a Western-style castle ahead!

"You're amazing, Ai! Let's head over there now!" Miyano Akemi said excitedly upon seeing this.

"Well... I'm not that great..." After being praised by her sister, Haibara felt happy, but on the surface she still acted as if she didn't care.

"Heh, is Ai Haibara a siscon?" Conan thought to himself.

Soon, the group finally arrived at the castle gate.

This castle is obviously suspicious; who would build a castle in such a remote location?

I smell a case!

[It's been so long since we've seen Asakawa and Conan solving cases together! Aoyama, that old scoundrel, finally remembered my husband, waaaaah...]

"Huh? Genta, what are you doing?" Before Professor Agasa could finish speaking, Genta had already climbed onto the fence of the castle gate.

Just as Genta crawled over, a pair of large hands grabbed him from behind!

"Hey kid, where did you come from? How dare you barge in like that!"

Seeing that things were going badly, Dr. Agasa quickly spoke up, "Sir, we are not bad people at all."

"Hey? Who are you guys?" the person asked again when he saw there were other people at the door.

"Actually, we just happened to be passing by and saw such a magnificent castle. If possible, I wonder if we could go inside for a visit..."

"All of you, get back here! This isn't a place for idle people like you..."

Just as the gardener was about to shoo them away, a deep voice came from behind, "Oh dear! Who are these people? There shouldn't be any guests visiting today."

"Oh, sir, actually it was that stupid-looking old man who asked me to let them in," the gardener said, pointing to Professor Agasa and the others at the door.

"Hey hey hey!!! What do you mean by looking stupid?! I'm a scientist, for goodness' sake! And Yu, why are you laughing too?!"

Seeing Asakawa Yu, who could no longer hold back his laughter, Dr. Agasa felt as if the whole world was against him.

"Hahaha! Sorry, Doctor, I didn't mean to, hahaha!!!"

[Professor Agasa: That's right, a science researcher!]

What a brilliant scientist!

"Oh, so you're saying your mind is much smarter than ours?" the man the gardener addressed as "Master" suddenly said.

"Alright then, please come in. By the way, would you like to stay here for the night?"

Upon hearing that he could stay overnight, Professor Agasa instantly became excited, remembering the scolding he had just received. "Oh! I'd be extremely grateful!"

"But sir, is it really alright to do this without consulting the madam?" the gardener asked hastily, as if he had just realized something.

"It's alright, just say they're my friends, that's all." After saying that, the man didn't say anything more and walked away on his own.

Afterwards, Asakawa Yu and Professor Agasa were led by the gardener to tour the garden.

Although she called it a visit, Asakawa Yu's mind was already far away.

Upon arriving here, Asakawa Yu remembered what the case was. That's right, it was the Blue Castle, which was known as one of the childhood nightmares!

This episode left a deep impression on Asakawa Yu when she was young. Besides the legendary treasure, what frightened Asakawa Yu the most was the terrifying face of the First Madam.

Now that she was here, she naturally wanted to see the so-called treasure. However, Asakawa Yu was still skeptical that the treasure left behind by the owner of a castle would be something like scenery. So, Asakawa Yu decided to investigate on her own...

"What's wrong, boss? Have you discovered something amiss?" Seeing her boss lost in thought, Miyano Akemi assumed he had discovered something again.

"So... that's not entirely wrong. Let's put it this way: this castle might be hiding a secret that could shock everyone!"

"...Is that so? Then please, boss, let us all see it, let us see the secret you mentioned, how about it?" Miyano Akemi had no doubts. Since her boss had said so, she just needed to believe him unconditionally!

"...Seriously, you're just adding to my stress." Asakawa Yu chuckled, seeing how much Miyano Akemi trusted him.

Unbeknownst to them, neither of them had fallen behind, nor had Professor Agasa and the others. Only Ai Haibara watched them from afar, a barely perceptible smile playing on her lips…
