Fatal Frame III: The Tormented

You just need to be in your 2nd play.
In Hour X, go to Stairs Hallway and move the dresser blocking the door. Walk across the roof to another door. Take the Purple Diary 4 and open the wooden panel where the Crying Woman was. Go down the ladder and defeat the Woman Brushing to get the Holly Key (and a Pierce lens). Now go back to Kimono Room and use the key on the mirror stands drawer. You'll get an earring and a photo, and you're ready for the ending. ^^
Good luck. ^^

Actually, You have to beat Kyoka (Woman Brushing) on every fight you encounter her in. Then, in Hour 10, you go to the Stairs Hallway and push the chest that's blocking the last door of the corridor, since you're in control of Kei and he's the only one that can push chests. Then you go through that door you just pushed the chest from, through the roof, and you arrive in the "Closed Room". There's an item right in front of you and as soon as you pick it, there'll be a chance for a shot at "Crying Woman" just near the trapdoor.
Now you go to the trapdoor the ghost appeared by, search it and it'll open into a ladder. Go down that ladder (midway along it, a Woman Brushing fight will star, but keep going down). Now you have to defeat her here (last one with her too, in order to get the ending you want). When you defeat her you'll get the lens Pierce and a cute little Holly key. Go to her Room (Kimono Room) and examine the desk with the smashed mirror and plucked hair, and you'll find everything you need to get the ending. After getting this stuff, just proceed on with the game and you'll have the "other" ending <3
