At first, the black shadow was seen by the roadside, seemingly waiting for something. However, the next day, it was confirmed to be following Natsume since it had arrived at the front gate of the Fujiwara's fammily. When Natsume took off to school, he tried his best to avoid the black shadow by the front gate.
