Did you take the correct path through the Torii gates after entering the shrine?I did and I get to the end where there's some kind of shrine with some fire urns (?) but the white haired girl is not there... What am I missing?
1. Go up through the single gate in the middle.
2. Then go left and go back to the bottom of the screen through the 2 gates in a row.
3. Go to the right side and go up through the 3 gates in a row there.
4. Now a blue flame will appear above the first gate. Go an examine it.
Each time you pass the gates in correct order the screen should shine / light up.
Only after taking that small course will the boss (the possessed white haired girl) show up at the end of the shrine between the torches in the room there.
