Tulpas are also called imaginary friends, and are fictitious beings created to protect their personalities.
In Anime and game worlds, they act as peripherals that allow the protagonist to experience reality-altering paranormal phenomena.
The prince may be cursed to become a tulpa.
In some cases, the main character girl likes him in the state of talpa.
However, there is no guarantee that she will like the reverted tulpa.
Tulpas lose their voice or become invisible when they or their master reach adulthood.
