Is that also possible for a soul eaten by a demon ??
Well he is a former shinigami so maybe he could have done something about it. Or he just really wanted to bring Real Ciel back at any cost, even by putting another person’s soul (someone also said that below)
Well putting someone else's soul seems logic, but it feels like it's the real ciel when he appeared he was angry at our ciel for what he did to him maybe he meant summoning the demon and sacrifice him at that time ! It would sad to see those twins fighting each other TWT
I don’t know
remember when he fabricated "what comes after the end" on his experiments before? thus may have been the case.
As a comment below said, in chapter 109, it may be Real Ciel the Undertaker is talking to.
And if I remember correctly, the Undertaker is a former shinigami ..
what if he was the one in charge of recovering the souls of the phantomhive at that time and decided it was unfair or something for Real Ciel (and/or the whole family), took pity on him which made him quit being a shinigami and start searching for a way to bring back Real Ciel for whatever reason ?
Hmm ..
