Meitantei Conan OVA 05: Target wa Kogorou!! Shounen Tanteidan Maruhi Report

Conan and his classmates are assigned to investigate a local business for a school report. The Detective Boys choose Kogorou Mouri's agency, but a simple interview is far too dull for them. Determined to learn what a detective really does, they secretly follow Kogorou through an ordinary working day, dragging a reluctant Conan and Ai along with them.

The harmless class project changes when Kogorou's current job takes a dangerous turn. Suddenly the children are no longer merely observing a detective at work, and Conan must understand the case before their curiosity places the entire group in the middle of a real crime.
