Foggy Foot is a story about a mysterious incident and a male (Adam) and female (Wako) pair who solve it in a Nordic country where humans and fairies are both present.

In the first episode, a boy, Yuta, an international student who came to Stockholm from Japan, met a beautiful woman in the forest, and talks about it to a Japanese girl, Wako, who is also a Japanese student. Yuta is depressed because he forgets the woman's name, but Wako notes that "if you know it, you will be obsessed with it," and "being aware" means that the "power" contained in it will be stronger.
