This one's from an old anime series called "
Umi Monogatari".
A little girl named Urin, who is the younger sister of the
main heroine, gets possessed by a dark spirit in the midpoint of the story.
Later, she gets completely taken over by the dark spirit in body and is forced
to grow a bit. After the heroines make peace with the dark spirit, she is set
free from control, and her body returns to normal. Both

sequences were done through shilhouettes, but the process are somewhat
noticeable.
