A man jumps off a ledge of an apartment building at night, which causes much commotion from the coworkers. Yasuhiro and Saori Takashima are requested by the man's wife and father to take care of a cat with heterochromia. The two go on thinking that its two different colored eyes are to bring them good luck in life. Sooner than later, Saori becomes attached to the cat, even to the point of calling it her son, to which Yasuhiro becomes concerned for his relationship with her. Before Saori returns from the store, Yasuhiro realizes that the cat is able to speak. As he tries to pry the cat away from her, she stabs him in the chest with a kitchen knife, leading her to jump off the ledge due to trauma. Miyu comes to confront the cat, a shinma called Han-Ki, returning him into the darkness.
