Air date: Jan 17, 1988

After forming the Detective Group, Takashi and his friends are faced with the immediate problem of not having a secret hideout that only they can use. The five of them were at a loss, but they never gave up their search and finally found the perfect place. For some reason, they found a German U-Boat (submarine) buried in a landfill on a riverbank, which they thought had been used in World War II.
