Neo Yokio is regarded as the greatest city in the world, in part because it is North America's most populous urban agglomeration. It is also a diverse labyrinth of innovation that is at the forefront of global fashion and finance. Among its residents is lovesick Kaz Kaan, the youngest member of a family of "magistocrats," pink-haired demon slayers who once liberated the city. He isn't that into the demon-slaying, though, and would prefer to go shopping, play field hockey and try to mend his broken heart. Kaz has friends Lexy and Gottlieb by his side as he navigates life in Neo Yokio while trying to stay a step ahead of archrival Arcangelo Corelli, the city's most eligible bachelor.
