I dont remember that well but all of those mini acrs are the characters investigating the organization that draws blood from people. I dont really remember why they do that but it's related to the whole corpse thing. Right now our Ciel is framed by the real Ciel as the mastermind so they need to clear his name
*Spoilers Ahead*
All the blood collecting organisation's relate back to rCiel and Undertaker's master plan that we r yet to explore. Basically rCiel is after oCiel to dethrone him but this entire thing is actually undertaker's plan and execution, as oCiel's elder twin has been dead for a long time. So oCiel is investigating these institutions to cut of blood supply to rCiel as he is a high level puppet corpse as well.
( oCiel: the main protagonist that we know and love)
(rCiel: the main protagonists elder twin)
right, okay, Ty both SM!
dgmw I adore following finnian and snake boy, I just have no clue how this all relates back to the ciel storyline... lemme go find a video essay or sumn
