Yes, I think so. The editor-in-chief back then didn't like Magic Kaito very much, and he said, "I'll treat you something if this gets sold as volumes and sells 100,000 copies." Then the number was passed in the blink of time - I thought, it's profitable to sell volumes, isn't it? After that, YAIBA started at the magazine, and since the magazine is weekly, volumes came out quickly, too. Things became much easier after that, not only in terms of livelihood but psychologically, too. I did become busy and lost time to have some fun, though. Conan was decided when I met up with the editor to discuss what to do next after YAIBA ended. At the time, Kindaichi (from Kindaichi Case Files) started at Shonen Magazine, and since I like mysteries and it seemed interesting, I wanted to have a go at it. At first, I/we thought about a hardboiled-esque comedy with a title like "Tale of a Detective" or something similar. But Conan is the royal road to shonen manga, isn't it? Becoming small, and then getting threatened by bad guys. The plot was finished in about two weeks, but it's not something I/we thought neurotically about. Conan turned back to a first grader, since Shinichi is 17, so I thought that turning back exactly ten years would be easy to understand. I get asked if why I chose first grade, but that's pretty much all the reason (laughs). Although, there also was a bit of an aspect that, since first graders are completely children, someone that age will be laughed at and then forgiven for doing anything.
