Don't even ask why ... The plot bunnies my brain comes up with confuse the hell outta me.

Jirokichi Suzuki/Kaito Kid. Yup, you read that right. Prepare for the crack!

...

It started with a heist note in the paper. One that Kaito had not sent.

He eyed the reprint of the note speculatively as Hakuba leaned over his shoulder. "And what is Kid up to this time?"

"Hell if I know," Kaito shrugged, hiding his irritation at the interruption. He refolded the paper, making it disappear in a tiny puff of smoke as he thought about the message hidden in the note.

...

"Hello again old man!" Kaitou Kid greeted cheerfully as he popped in to Jirokichi Suzuki's home office, "missed me so much that you had to announce it in the papers?"

"Kid," the elder Suzuki replied grimacing at the thief's mild taunt. On closer inspection Kid noticed that Suzuki was looking worried and tense.

"Did Lupin get himself locked into the vault again?" He asked as he threw himself into one of the comfortable chairs in front of the man's desk.

Suzuki's eyebrow twitched at the thief's familiar manner but did not burst into one of his usual tirades. The lack of outburst surprised Kid. He leaned forward as Suzuki replied, "No, it is much more serious than that." He paused before continuing uncomfortably, "I have a ... business proposition for you."

"Oh?" Kid's ears perked up as the Suzuki Company's advisor continued, "There has been a breach of security within the company. Someone has gotten a hold of some very sensitive information and has been selling secrets to our rivals. Internal efforts to catch the individual responsible have been unsuccessful. This company means a lot to me and my family. I am willing to do whatever is necessary to protect it, even if it means-"

"Calling in a thief to catch a thief?" Kid interrupted. He grinned toothily at the older man who gave a resigned sigh.

"Unfortunately, yes."

Kid's smile widened. "Now that sounds interesting!"
