She finds an egg nearby the crow and brings it home. She notes that the egg grows incubated below her pillow and inside a teddy bear later but soon the egg hatches into a bizarre bird-like creature. Tinja raises and is connected to the creature that is her alter-ego for evil desires that Tinja hides in her apparent perfect world.
