少女幻葬~Necrophilia

Synopsis

Georg and Riselotte are your typical brother and sister, except the former's a priest and the latter's "alive" by way of…darker methods. As a result, Rise is stuck in a child-like body. Georg immerses himself in research to free Rise from these chains. Note: This manga is about necrophage and not necrophilia. However, the correct title is still necrophile.
