This bundled OVA follows Doppo Kunikida, the rigidly methodical member of the Armed Detective Agency who runs his life by an ideal schedule written in his notebook. Atsushi Nakajima peeks at the packed list and doubts Kunikida can keep to it. When a bomb-related case throws his plans into disarray, Kunikida is forced into a choice between a single life and many. The side story was released alongside the manga rather than as part of the main TV run.
