They would have succeeded if Ciel Phantomhive hadn't made a deal with a demon. The demon will help him track down and eliminate his parents' killers in exchange for Ciel's soul. Until they find out who murdered Ciel's parents, the demon must obey his every command.

The pentagram is the mark of the contract between the young Earl Ciel and the devil Sebastian. This 3.3 cm diameter metal amulet features an embossed pentagram design. The pendant comes with a chain approximately 52 cm long.
