Hotaru gets a letter from her friend in Tokyo while Hikage shows Renge her own pictures of Tokyo Tower before having to play dolls with her. Later, Hotaru ends up losing her bag on the bus, so she, Renge, and Hikage make their way over to the bus depot to look for it, coming across various sights along the way. Afterwards, Hotaru manages to work up the courage to dive into the river for a picture to send to her friends in Tokyo.
