"It's probably the combination to a bank safe deposit box," Guangyou guessed. "Perhaps it contains incriminating evidence against that lawyer Ito?"

"Forget about the code for now." Kōyū pulled Ai back to their seats and began to think about the specific details of the rescue plan.

In fact, there are only a few ways to handle this situation:

The most reckless approach is to charge headlong into the enemy, but this is the riskiest method. It might guarantee your own safety, but there is no guarantee for the safety of the hostages.

Another approach is to take them down one by one, which is the method Guangyou chose.

However, what troubled him was how to disperse those people.

Do I have to go and borrow the restroom?

That would be highly suspicious.

Just as Kōyū was thinking about how to separate those people, Conan's voice rang in his ear.

"Kuangyou, are you thinking about how to get one of them to leave?"

Mitsuyu wasn't surprised that Conan had guessed his thoughts; it would have been truly astonishing if Conan hadn't.

Looking up at Conan's expression, Kōyū asked, "You have a plan?"

Since Conan asked this question, there must be a solution.

"Yes, I've already asked Hattori to find a way to lure them out." Conan nodded and added, "The rest is up to you."

“Leave it to me.” Kōyū looked at Ai, and after noticing the worry in her eyes, he smiled at her. “Don’t worry, how could I possibly fall into the hands of those few scoundrels? You eat here, I’ll be back soon.”

After saying that, Guangyou got up, made up an excuse, and left the restaurant.

Now that his problem has been solved, there's nothing more to consider.

“I’ll go too.” Ai stood up with Kousuke, looking directly into his eyes without backing down, and said calmly.

Looking into Ai's eyes and sensing her determined gaze, Kōyū thought for a few seconds before nodding in agreement.

"Then you must wait for me outside."
