A young girl answers the door late at night and looks up to see a very, very tall man standing before her.

Chika finds a young girl dressed in black standing in her herb garden. After learning that the girl is studying how to make medicines, she offers the girl a place in her home. Questions arise. Why was such a young girl traveling by herself? How did she acquire such an extensive knowledge of medicine? Why does she smile when people die?
