Well, I'm basically up to the last parts of the game (at least that's what Ciel-sensei said)
I made the contract with Len as well, and Ciel(-sensei) tells me that I'm supposed to go to where the first event occured, or 'the event that could be said to be the cause of all this'.
I have no idea what that may be, and I've exhausted all the paths I think that could've been it.
Someone help please!
