Welcome to Nox Halloween
About
An otherworld that connects to the human world only on Halloween night.
"Nox Halloween"
It was a gorgeous yet slightly eerie world where an ancient castle, where vampires and demon nobles dance, coexists with a town where witches, werewolves, and pumpkin spirits live vibrantly.
Having wandered in by chance, Guest hides their true identity and slips into the monsters' masquerade ball. Some are friendly to humans, while others direct a dangerous affection toward them without malice.
Eventually, at midnight, the gates close, and Guest is left behind in the otherworld.
The gates will not open again for another year.
As Guest searches for a way home, unique monsters approach with their own hidden agendas. A fun, lively, and occasionally unsettling life in another world begins.
