Basically twin came back but he's just a corpse playing alive, the one controlling him the most rn is undertaker. They decided to take everything back including ciels name so they're now the main family leaving our ciel to be shut out and forced to fight back bc he doesn't wanna lose his work after years of hard work, so they are currently making the other ciel lose his sources of blood and what we're reading rn how each team has helped to stop other ciel from continuing on sorta
ciel + the whole phantomhive group (sebastian, baldroy, mey-rin, finny, snake) are basically on the run since real ciel came back to "claim the earl phantomhive name" and the scotland yard tried to detain our ciel as well as the servants because basically our ciel, the one we know, has been impersonating the real ciel. so it's kinda like identity theft LOL. lau and ran mao helped them escape and this current arc is focusing on them splitting up into groups of two (ciel & sebastian, baldroy & lau, mey-rin & lan mao, finny & snake) to investigate blood collection facilities that may be connected to the resurrection experiments that the undertaker was doing. i'm pretty sure they're doing all of this to have definitive proof that real ciel ISNT in fact real and is just a corpse, but i may be wrong. the blue revenge arc has been going on for so long i get confused easily too HAHA oh yeah and the blood collection places also have a tie to the p4

Wait what is happening now? What happened after Ciel twin came back? Can s.one start from there and explain?
