I Transmigrated into Detective Conan and Became a Lousy Side Character

No CP-breaking. The female lead is a character from another anime. This is a story about an ordinary person transmigrating into the world of Detective Conan and coasting along. The protagonist rarely solves cases and isn’t much of a fighter, so they mostly keep a low profile in the main plot, only occasionally relying on the Professor’s brand of high-tech gadgets to put up a fight. All characters in the story are adults.
