Эпизод 21

Naoto tells Yu that she cannot find out anything about the sender of the "Stop helping people" letter, but she knows that it was personally delivered so the sender knows who they are. Later, Naoto worries that she is more focused on solving the case than she is worried about Yu's safety like the rest of his friends. Yu arrives at home just as a delivery truck leaves, and as he and Nanako have dinner, a news piece about a local politician's visit to Nanako's school airs, with a mention of a student who impressed him. When Nanako feels sick, Yu puts her to bed, and promises her that they will build snowmen together before he goes back home. A week later, Yu sees an unknown figure on the Midnight Channel, and asks everyone to watch it the next night. Nanako seems to want to give something to Yu, but her illness interrupts her plans to give it to him. Dojima comes home, holding another letter for Yu, which states "If you don't stop, the next one to go in and die will be someone dear to you".
