Conan recalls what happened before the explosion:
"Strange, why can't I get it in?"
"Maybe there's no lock or anything like that."
"I think that must be talking about the toilet door!"
Megure Jusan was stunned, and looked at Nakajima Hideaki and the other two:
"The toilet in your company..."
"Is it still locked?"
Nakajima Hideaki and the other two looked at each other, shook their heads immediately, and said solemnly:

Conan suddenly had an idea and realized something was wrong.

"Um...excuse me."
"I'm Ishikawa, the president of Mantiantang Game Company."
President Ishikawa opened the box and took out a card:
"Actually, two days ago, I received a threatening letter..."
"What?!"
Megure Jusan glared:
"Why didn't you notify the police earlier about such an important matter?"
