Kaseifu no Bukimi
家政婦のブキミ
A temporary housekeeper named Kotobuki-san comes to the home of fourth-grader Takuto and his second-grade sister while their parents are away for five days. Initially, the environment is pleasant, but odd occurrences begin to unfold. Kotobuki-san introduces unusual rules, a neighbor's dog disappears, and the younger sister has a fall down the stairs. Takuto grows wary and starts to look into Kotobuki-san's background to uncover her true nature.
