Aki lives alone in the sprawling Estate de' Sukari. She wakes from a nightmare in which she sees her own death, then hears a shriek from somewhere in the manor. The game she faces has no weapons: only evasion, observation, and the knowledge that the undead and other things now move through the halls alongside her. The estate contains five distinct areas — a second floor with her father's and her own rooms, a ballroom, an art gallery, a dining hall, a library — and a garden maze. The cats can offer useful advice.
