Overview
Almost all of the dialogue and narration is extracted from the original work, with only minor differences in the storyline as follows. Yashiro Ryusuke's own home is located on Y Koji. When he first accompanies Kanako on the road, Kagawa meets her in front of Yashiro's house, and Kamei also appears there. Dr Asano's wife did not show up. It is explained that Kagawa has two girls (in the original story, one is a student at a girls' school, but the gender of the other is unknown). The introduction of the 'one in 500 murderers' is told against the backdrop of Kindaichi excavating an air-raid shelter (which appears to have been made from a natural cave).
