Megu uses her photographic memory to get out of trouble and Kyu figures out where the missing money is. As a form of gratitude, the old man treats them and tells them that he is in a hurry as he needs to go to Hokkaido, where his daughter is getting married. Later, Kyu and Megu see a man on the rook of a building being constructed, waving a torch, and jumping. As they run there, Kinta joins them and they see the dead man is the old man they met before. Even as the police are about to conclude this as a suicide, Kyu tells them it can't be, since the old man wanted to go to Hokkaido. He starts searching for the only clue left behind by the culprit in the grounds, and is even joined by Kinta and Megu who help him out. After he solves the case almost single handedly, Kinta and Megu tell him about the Dan's Detective School/DDS and Katagiri hands them the guide to the enrollment program.

As Kyu and Megu retrace their steps, they are halted by a cry of help, from a man who has fallen down the cliff and has broken his leg. Kyu deduces this to be a trap to stall examinees and they leave the man. But later, he hears a siren, signaling the release of water from the dam.
