Tantei Gakuen Q EP3 - Final Exam! The Stretched-Around Trap

A few obstructions are met during the exam, which the group solves using the wits of Kauzuma. However due to the interference of Saburōmaru, the group is split up when a bridge breaks beneath them, with Kinta and Kazuma proceeding to the exam hall, and Kyu and Megu being swept away quite a distance by the river. 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. Kyu returns to help the man, who in turn, encourages him to not give up until the end. Kyu enters the exam hall with 10 minutes to spare and declares that he wants to take the exam. In the end, Kyu is able to solve only one question. Even so, he is admitted to DDS, since Dan tells that the question was one of the most difficult cases encountered by himself, and only one more person has been able to solve it so far.
