Beika Stage: Starting Out as Shinichi Kudo

A decade-long Detective Conan fanfiction veteran finds himself transported to Beika Town, bound to a role-playing system. The system orders him to act as Shinichi Kudo and solve cases. He reluctantly agrees—mainly because the package comes with a free childhood sweetheart. But the system isn't done with him yet: next, he must also play the role of Sherry, climbing the ranks of the Black Organization step by step to the very top. And when he takes on the role of Kamen Rider, all evil forces will face the righteous beatdown—prompting Sherry to nervously ask, "Does that mean I get beaten up too?"
