Conan had come to Osaka with Ran due to Kogoro's detective work. Today, Kogoro was meeting with a client while Ran was out with Kazuha.
Conan had originally planned to tag along with Ran, but...
Hey, Conan! Since you're comin' to Osaka, why don'tcha hang out with me?
Hearing that, he changed his plans and decided to go with Heiji. Conan then arrived in front of a certain TV station.
Jeez, why'd you call me all the way out here?
Well, y'see, I found somethin' that don't belong at a TV station...
What's this?
Apparently it was being shown on the huge screen inside the building... Dunno who did it or why... Could just be a prank by an employee or whoever, so the police haven't been called in yet...
So they called you in to investigate instead?
That's right! I'm in touch with one of the employees here, and they requested me to investigate in secret... Who better to ask than the Great Detective of the West, right!?
S-Sure...
And since you happened to come down to Osaka, why not investigate together? Besides, we found someth'n else suspicious...
...A Code Book!? Like for puzzle-solving?
Yeah... Got ya excited, din't it?
You're one to talk, Hattori!
And so, the two decided to investigate based on the new information they found.
