Just after the beginning in the second chapter.
Page 32: "I don't care about that thing"
Page 33 "that ring is the proof that the head of the Phantomhive family is "Ciel Phantomhive""
I knew Ciel wasn't Ciel since the "Who stole the candy from my tummy" part
But just before that there were some hints like when the main character remembered to the summoning of Sebastian
Damn I've never got anything like this right and yet I wasn't wrong this time.
My main point was that the main character never said his name was Ciel Phantomhive. He said that the head of the Phantomhive family was Ciel ╮( ̄▽ ̄)╭(๑•ㅂ•)و✧
