Detective Conan: Miyano Anjian Doesn't Want to Solve Mysteries

Original male protagonist. Shiho Miyano's twin brother, Anjian Miyano, is captured by an organization member named Finette while trying to uncover the truth behind their parents' deaths. To cover up Anjian's betrayal, Finette decides to take him to Italy. While there, neither of them is trusted by the organization, so Finette uses her own death to help Anjian regain the organization's favor.

After returning to Tokyo, he discovers by chance that he isn't the only one inside the organization plotting a rebellion... He'd better make good use of that.

He tries to keep his wits about him and slack off, but never succeeds.
