When you wake up- Carnations, fountains, perfect peaches! ...Wait, what's with the ground? I believe Aika was a girl visually impaired. A few Jacob's Ladders at the back. Aika loved flowers, like your pretty princess type. In the house!
In the first house- Aika's celebrating her birthday! Hooray! A gift sits near the table. It was another dolly to add to her collection of toys. Upstairs, in Aika's room, you see pictures of her dog, mother, and family.
In the second house- You have to swivel through the chairs to get through, because it's blocked by black objects. Those exit signs means Aika escaping her trauma. In the right room, there is a group of these owl clocks staring across an angel and a demon. I have no idea what that means. Left, there is a bunch of wheels which mean the wheel of fate, made by the shark, which is the dolly. In the back room, there is some eyes on the wall and toys staring away. Meaning that she thought her toys were moving away. Upstairs, there is Adam, Eve, the forbidden fruit, and the snake. I'm guessing she was a catholic girl. Since Eve ate the fruit, every other woman would be punished. Downstairs is the last supper. It seems innocent before you realise that one dolly has an axe.
In the third house- Bookcases. Bookcases. In the right room, there is some eggs and a piano, showing that Aika's parents wanted to make her perfect. Upstairs, there is a room decorated with Aika's drawings as a child. Right now, she is in her late teen years. Downstairs, you see an outline on the bed. This means that the dolly killed her mother. Aika fell pregnant soon, and the father divorced years ago. Having only herself to take care of, she plunges into depression.
In the fourth house- Aika is now a young adult. Everything is now in disarray. The dolly, upstairs, tarnished the room. Now, you see Aika stuck inside a cell with her dolly. The dolly ended her hectic calamity; She now has Aika all to herself.
