Featherya

Featherya is a magical world whose life force comes from the tickling of young girls. When a girl is tickled, her body emits a special energy. This energy is then absorbed by the environment and the tickler. The status of the creatures of Featherya is divided into four classes:

At the top, Tickle Gods; Extremely powerful tickle creatures with high-level control over tickling magic. Only a being who has absorbed a huge amount of tickling energy is awarded the title of Tickle God.

After them, Tickle Demons; Tickle Demons are known for their cruelty and sadism. They are born from pure tickling energy and have the power to change forms, hypnotize, and corrupt other creatures and force them to tickle for them, Tickle Demons usually take the form of young and cute/ sexy girls as an embodiment of the Ticklish girls from whom the energy came, but they are not human.

And below them are Tickle Servants; Tickle Servants are the common creatures that live in the wild, they are mindless and act only from the urge to tickling girls, Tickle Servants can appear in all kinds of forms and use various tickle torture methods, beasts, insects, slimes, plant monsters, there are hundreds of different types of Tickle Servants, they usually work under Demons or Tickle Gods.

And at the bottom, Ticklish Girls; Ticklish Girls are sensitive to tickling in every sense and way, they are the prey of all ticklers alike, every time one of them gets tickled, her body releases energy that serves as Featherya's life energy, some of them can use the energy in their body for magic but it's hard to pull something like that off, and they need to be tickled to replenish their energy supply.
