That was...a really weird way to put it. Conan frowned thoughtfully. "So...something about the 'enforced company' lets you have power over what your Shinichi said. And whatever this is applies to Hakuba, and possibly Nakamori-keibu and Heiji." Rivalries did say it was with more than one person and Hakuba had definitely been the main rival. The other two were the only other ones he could think of as possible candidates.

"And the way you said it...it sounds like it's more than just simple blackmail. Not just a 'you tell my secret, I tell yours,' especially since that wouldn't apply to anyone aside from me and maybe Heiji if only because he wants to keep my secret." Even with blackmail, he could still tell.

With the way it was said though, it sounded like he was incapable. "Did Koizumi cast a curse on you guys?" Well, it was a possibility.
