Ok, so at the end they go to that bench because Ceil dies, Right??
And then Sebastian eats his soul, WHAT HAPPENS NEXT?!
Isn't there a part two? how is he alive in that. Help please!!
There is a part two and Ciel apparently comes back to life (I'm watching the second series right now). They explain why he is still alive (*SPOILER* Ciel is turned into a demon so Sebastian never ate his soul and is stuck as his butler for eternity).
Haha, I was confused the first time I saw it too. XD
So, you know when Sebby got his arm cut off? That was the arm with the transmutation circle or seal or whatever you wanna call it on it. Without that he wouldn't be able to eat Ciel's soul.
Also, just watch episode 2 of Black Butler II at the end (after the end theme) and it explains a little bit..
