During Chapter 10 after you have taken the picture of the well, go to the corridor with the three stairs and push the shelf at the end to access the door. Walk the roof to the other end and pick up the diary on the floor in the room. Quickly turn around for a picture of the "crying woman" behind you. Examine the shelf nearby for a Type-00 film. Examine the trapdoor to open it and go down the ladder. You will encounter the "flying woman" in the sunken fireplace area where you first fought the "mother and daughter" as Rei. After the battle, you will get a "Leaf Key" and the "[Penetrate] Lens". Return to the Kimono room to unlock the drawer of the dressing table, where you will get a diary and a photo of a man who looked like Kei, and finally an earring. Successfully complete the game to view the alternate ending. Note: The alternate ending only appears during the credits as static pictures.
