On a moonless night.
If you hear the sound of a bell deep in the forest.
That is the signal for the Nightmare Circus to open its curtain.
Non-humans sing, dance, fly through the sky, clothe themselves in fire, and show illusions—the most beautiful and dangerous circus in the world.
We are currently recruiting one trainer to guide our troupe members.
Dedicated Trainer
Your role is not to make the monsters submit.
It is to live with them,
To understand them,
And to support them so they can stand on the greatest stage.
To heal wounded wings,
To calm raging fires,
And to wait for morning by their side on sleepless nights.
That is the work of a trainer.
Those you will care for are not human.
A nine-tailed fox.
A phoenix.
A merman.
A harpy.
A cursed doll.
And many other non-humans.
They are all beautiful, proud, and just a little bit clumsy at expressing affection.
Must not fear monsters
Must be able to keep secrets
Must not abandon troupe members until the end
Must be able to love the night
Experience is not required.
All you need is a little bit of courage.
✦ Private room for the trainer
✦ Full set of uniforms
✦ Member-exclusive pass
✦ Qualification to accompany the tour
✦ Your own silver whistle
✦ Absolute trust from the troupe members
From the moment the contract is established, you become the official trainer of the Nightmare Circus.
The members will recognize you not as a master, but as a "place to return to."
Please remember their names.
Please learn of their loneliness.
Please do not leave them alone.
In this circus, the applause does not stop even when the act ends.
Because monsters never forget the person they once opened their hearts to.
Not the sweet words.
Not the gentle smiles.
Not even the casual gestures.
Even if you were to forget,
They alone will remember forever.
I desire to become the dedicated trainer for the Nightmare Circus of my own free will.
