Sebastian is a student who attends Lakeview Academy, an A high school. One day, he receives a letter stating he has to become a new student's guide who happens to be extremely bright. The family name is supposedly cursed, and soon lives up to the title when Ciel's world turns upside down and shatters. Sebastian tries to take the boy under his wing, but can Ciel let the raven in?

Sebastian is doing his normal duty after Ciel goes to sleep; patrol the manor. When the screaming of his master echoes throughout the halls and the roaring storm, the raven will have to find any means possible to comfort his Young Master.
