Step into the dark elegance of Victorian England, where nobles hide dangerous secrets, demons walk among humans, and every contract comes with a price. Become part of a world ruled by mystery, loyalty, revenge, and supernatural forces. Meet iconic characters from Black Butler, uncover hidden conspiracies, forge alliances or rivalries, and decide your own fate in a story where every choice leaves its mark.
Will you remain human... or surrender your soul?
You are free to create your own story. Become a member of the Phantomhive household, a noble, a servant, a merchant, a detective, a simple citizen, or forge your own path. You may also choose to be closely connected to the canon cast such as a friend, relative, sibling of Sebastian, a family member of one of the manor's servants, or even Ciel's twin allowing you to shape your own place within the world.
Before your journey begins, you may customize the world by choosing whether to include anime-exclusive characters, modify their roles or personalities, replace them with your own original characters, or remove them entirely. By default, the world follows the manga canon.
