"How could that be? We'll definitely find it." Guangyou was very confident.

"Good luck." Ai smiled as she looked at Kouyu's confident demeanor. "Then I'm going to find a place to hide."

"Go quickly, find a good place." Kōyū watched Ai's departing figure for a while, then lowered his head, took out his phone, and made a call to Hattori Heiji.

"beep..."

A few minutes later, the call was answered.

Heiji Hattori's voice came from the other end of the phone: "Kuyou, what's up?"

It might be a misperception, or it might not, but Guangyou always felt that there was a sense of weariness in his voice.

"Hattori, are you and Kazuha free this Saturday?"

Ignoring that for the moment, Kōyū got straight to the point and said the purpose of his call: "Conan wants to invite you two to Tokyo for a few days this Saturday. He said he'll take you to a newly opened theme park, and I heard there will be a big meal too."

"Saturday?" Heiji Hattori didn't respond immediately. "I'll go ask Kazuha first."

"It's okay, no rush." ​​Guangyou checked the time, and feeling that it was about time, he stood up from the bench and strolled slowly through the park, as if taking a leisurely walk.

His hearing was passable, and he vaguely heard Kazuha's voice:

"To Tokyo?"

"Theme park?"

"Okay, I'm fine with that, but Heiji, do you have time?"

Upon hearing this, Guangyou knew that the matter was settled.

So Guangyou didn't notice their conversation that followed.

Looking around, Guangyou began searching for the "criminals" hiding in the park.

He had only taken a few steps when he heard Hattori Heiji's voice again on the other end of the phone: "Kuangyou, Saturday, right? How many days are you going to spend?"

“Yes, Saturday.” Guangyou replied while searching for the “culprit.” “I can’t say exactly how many days, but it should be three or four days.”
