Reader's Guide

The supernatural side of this series turns on Faustian contracts between humans and demons. Bound by his contract, Sebastian must abide by Ciel's will; his contract mark is on his left hand, which lets him find Ciel wherever he is whenever Ciel's own mark is exposed, and in return Ciel can summon him and give him orders. As payment for helping Ciel achieve his revenge, the demon will consume Ciel's soul.
