A ruthless demon who bends to the orders of those who, in exchange for the lives of others, promised to return her brother.
Naru and Mira.
Tainted, damaged souls… yet somehow able to fit perfectly against each other. A journey straight to hell and back, where they'll meet others who were crushed, forgotten, and trampled on by life.
A journey that will make them long for a place in this world, a place that could exist even for the invisibles like them.
