The labyrinth of Pan God ends with Ophelia's soul returning to the underground kingdom and becoming a princess.

Pan Shen told Ophelia that she was a princess in the underground kingdom, and the old king had been waiting for her soul to return. But Ophelia wants to return to the underground kingdom, and she has to undergo three tests, but she lost her life in the third test. No one thought that it was her unwillingness to hurt her brother that made her a princess again.

There are two worlds in this movie, one is the real society, and the other is the fantasy world. In the real world, Ophelia and her mother live in the military headquarters of her stepfather. But his stepfather doesn't like Ophelia. The reason why he is with Ophelia's mother is just to use the children she gave birth to help him continue to rule the country.

In the magical world, Pan told Ophelia that she was a princess in the underground kingdom. After her death, the old king had been waiting for her soul to return, but she had to undergo three tests to return to the underground kingdom.

The first test, Ophelia, passed safely without any effort, but when the second test came, her life began to face threats. When the third test came, Pan told her to open the door with her brother's blood, but Ophelia didn't want to hurt her brother because of herself, and finally died under the gun of her stepfather.

At the end of the movie, O 'filia's soul returns to the underground kingdom. It turns out that being unwilling to hurt his brother is the key to winning the third test. Maybe only kind people can return to the underground kingdom to be a princess.
