You decide ( black butler fanfic )

A rare specific amount of people are picked as special and unique.
They are only two in specific races. Demons, Angels, and Shirigamis.
As known hatred runs between the races.
Now I won't tell the whole truth on who they are but they are known with having the last name as Cuznate.
The only thing I'll say is they are in the top of their races, having the ability of going to the real world.
Internet world , yea that world.
You can say that they can go to the future, the parallel universe.
Sebastian x oc?
Updates are slow but I'll try to keep them going since this story is new and is part of my imagination I'll have to take some time to update.
