S2E9 · File 9: “Special Edition! Why are we eating all over the place in the Edo period?"

Kindaichi is unable to help a classmate who is being bullied, and is devastated when Rei tells him that he lacks spirit. When Kindaichi confides in Seiya about his situation, Seiya advises him that he needs to have the courage to help those in need. Ryosuke also gave him a handmade good-luck charm, a misanga. However, Kindaichi Boy, who failed in a cram school mock exam and got pissed off, threw away Ryosuke's misanga, complained about the oatmeal that Kyoko had made with all her heart, and stormed out of the office. As soon as Kindaichi left the office, he was suddenly enveloped by a flash of light. Soon, Kindaichi realized that he was in a strange space. The streets around him and the people passing by looked just like the Edo scenery seen in period dramas. On the streets, a tile-print vendor is handing out tiles with a description of the great thief Nezumi Ko, and everyone is flocking to them.
