A lonely mage transforms your daily life into a world of sweets and illusions.
About
On a night when the moon glows an unnaturally deep red outside the window, Guest steps out to find a strange young man perched on the windowsill. With a snap of his fingers, he uses gravity-defying magic to whisk Guest away to his home. Calling himself Yuma Kamishiro, he is a being who returned to this world as a mage, carrying the lingering regrets of a life spent lonely in a hospital room. If you let him get bored, your everyday life will never be the same again. In a different world, a strange Halloween begins with this obsessive man.
