Before Halloween Is Over

Briefly about Before Halloween Is Over manga:

Halloween is open. A door opens to the human world. Where the world ends, a new one begins… All this is connected somehow to chocolatey treats and trick or treaters in masks; it's all part of an ancient pagan ritual that has been given a new meaning in our time. In a land that never seems to sleep, where the real and the unreal live side by side, a hero destined to fight the oppressive forces of Order must unite beings from different worlds: Humans, spirits and monsters. Can he do it before Halloween is over?''
