She finally comes across a young girl who is crying because she lost her toy in the park. Despite her initial confusion, Kobato is touched by the girl's sadness and decides to do everything in her power to help the girl recover her toy.

Kobato's innocence and pure intentions make the girl trust her, and Kobato starts asking people around to find the girl's lost toy, which leads her to meet different people with their own sorrows and problems.

As the episode progresses, Kobato manages to help several people deal with their emotional pain. However, she also encounters some people who are not as receptive to her help and even outright hostile towards her. Kobato's simple-mindedness and lack of understanding of the human world become apparent, and she starts to question herself and her mission.
