Akuma wa Yurikago wo Utau
悪魔はゆりかごを唄う
A pair of brothers trained as exorcists work to help those infected by a mysterious virus called "Devil," which spreads by inducing fear in its victims. This virus transfers from one person to another and cannot be removed by standard exorcism methods. Alongside them is a rogue exorcist who operates outside the authority of the Vatican.
