Fujimori, who majors in architectural history at university, visits the old Count Hachigaya's residence owned by the German noble Julian Ludendorff for academic research. The ancient mansion, surrounded by deep forests, is inhabited by the reserved Julian, two cats, and some surly servants. The area is so remote that there is no mobile reception, and there are no televisions or radio signals. The vast grounds make it impossible to go out and explore.
At first, Fujimori is disoriented by the closed-off environment. But as he discovers another side to Julian, whom he initially thought to be a rough man, he begins to find the situation unexpectedly enjoyable. To top it off, he spots a mysterious beast running through the forest in the early morning!?
