“Massive debt, a shabby brothel, and a naughty succubus… This is all I get for defeating the Demon God?!” Hire monster girls to attract customers and pay off your debts! Don't forget to give your girls lots of hands-on job training!

A sleep simulation where you play tricks on a sleeping girl.
You can touch her with the mouse.
Be careful not to wake her up, fill her heart, and
use the vial to put her into a deeper sleep.

Once upon a time, in a topsy-turvy world…
In the beginning, you find yourself lost within a world of utter darkness. Your memories are gone; even your name is a mystery.
But just when the bitter loneliness threatens to break your spirit, you meet Alice—a blond-haired, blue-eyed young man who promptly christens you "Arisu."
Like you, Alice cannot remember anything beyond his own name. Ignoring his protests, you drag him along with you through the darkness… until you happen upon a massive mirror made of crystal.
You stumble through the glass and into the Looking-Glass World, an antiquated fairytale dreamscape that feels oddly familiar…
There, amid a colorful cast of gender-swapped fairytale characters, you take on the role of the heroine and join them in their twisted tales.
