Godchild v01-v08 (2012) Complete

In London, England, during the late nineteenth century, a 17-year-old nobleman named Cain becomes the head of the Hargreaves family after the untimely death of his father. He is very quiet and seems to always be the odd one out, so he thinks of himself as a black sheep. As a hobby, Cain collects dangerous toxins, giving him the reputation as the "Earl of Poisons." His only loving company is his 10-year-old half-sister, Mary Weather, and his butler.
Each volume revolves around a different mystery, or dark horror that always seems to always seek out Cain in the "Capital of the Fog."
English translation of the Japanese manga Goddo Chairudo.
