Here’s the little long theory for the last Kuro chapter, resulting from a very nice discussion with @thedarkestcrow when spoilers came out for anyone interested 🙂 And I also thank @dorkshadows and @wondrouswatchdog for their help with some details. ❤
A warning though: I’m already aware that many people took the scene I’m going to talk about as a hint for the 2CT (understandably so), and while I respect all people’s opinion, since I chose to interpret it differently in this post I ask that you please refrain from commenting only about the 2CT (any version) in case you want to add your thoughts. 🙂
I don’t really want to start a dialogue of the death so thank you in advance ^^
((A TL;DR paragraph is at the very end in case you don’t want to read the long explanation.))
About Lord Sirius…


Considering how the Blue Sect arc was presented as supernatural with Bravat’s fortune-telling when in fact it’s about blood collect and probable blood transfusion experiments, I’m not ready to consider that the person is a vampire/Ciel’s twin/Ciel’s clone yet.
For me, Sirius is someone we don’t know and who’s very very old, judging by what looks like to be a typical case of varicose veins on his arms and hands. In case you don’t know what it is, just try to compare your arms with an elderly person’s (because google images can be a bit gruesome), you’ll see how it is a consequence and sign of advanced age. 🙂
Old age would also explain why it looks like his shadow and Ciel’s in ch113 are of the same height because most people shrivel after a certain age, but this is a detail really (because Yana could be 100% trolling us with the shadows).
Now before I propose an answer as to why Lord Sirius would need blood, let me go back in the timeline a little.
Remember the Campania arc? At some point after things got crazy, Ciel wonders just why the BDs are “supposedly” taken to America…

The Osiris company was barely ever talked about after this, and since Ciel guessed that it might be a phantom company, we readers never knew whether he investigated them or not.
But the thing is, it’s probable that this company really exists, because when UT is asked what was the point of the experiment on the Campania he answers:

and I’m thinking “that eccentric bunch” could refer to the Osiris company.
Now what’s the link with the Blue Sect Arc? Well, Ryan mentions a new drug (as in medicine) and the Blue Sect Arc definitely gives off a medical vibe with the blood collect and tranfusions, so maybe Yana-sensei intends to really introduce them in this arc.
Besides, it appears that they could be eccentric and if that’s not how to define Bravat, then I don’t know what adjective would suit him, haha! ^^
Back to “Lord Sirius”, I also consider for the sake of this theory that he is a part of the Osiris company, probably someone very important too, since both Bravat and Violet kneel in front of him, but he might not be the only “Lord” inside the Sphere music hall, as @thedarkestcrow explained here, which would make sense considering Lizzie’s behavior so far.
After all, Violet and Lizzie seem to be the only two really unhappy at the Sphere music hall and now that we have an idea as to why for Violet (they’re endangering him by taking his blood too often), it’s easy to think it might be the same reason for Lizzie.

It’s the Victorian era so, as Sieglinde and Wolfram explained, the blood transfusion technique is not mastered yet at all and I’m thinking discerning the 4 different blood types is all Bravat can do for now.
This is why they probably don’t know how AB types are universal recipients or O types are universal donors, so since the Sirius star represents the AB type, Violet has to give his blood when the mass collect during the week isn’t enough for Lord Sirius (because there are not a lot of people being AB, as we saw when Ciel went to the private event).
Same for Lizzie, if the Canopus private event doesn’t bring back enough blood during the week (second rarest type) then she probably has to give her blood (or radiance in Bravat’s words) to a Lord/Lady Canopus, like Violet does for Sirius. Why her and not Redmond though? Well, because…

The S4 are the poster boys for the Blue Sect, they’re very important to seduce the masses and bring even more people to the blood collect sessions, which is probably why Lizzie is giving her blood and not Redmond as long as Bravat can avoid it.
In Violet’s case though, he might be the only one staying at the Sphere music hall who is AB type, which is why he doesn’t have a choice even though he is a member of S4 (poor guy).
I hope these details make sense somehow, sorry this has to be so long (I’m not good at explaining with a few words :/). Now I’ll try to answer why Lord Sirius could need blood for, especially if the Osiris company is involved because it could be linked to the concept of immortality.
Considering the name of the company, it’s quite easy to think that it might have to do with the Osiris myth, which is about Osiris dying because of his brother’s jealousy and Isis his wife reviving him (nice summary here): it is associated with the idea of immortality (for the soul) and a regeneration beyond the grave.
I find that idea particularly interesting because it fits with UT’s bizarre doll project, since he is trying to bring people back from the dead through experimentation on cinematic records (souls are another step) and since it appears the Osiris company was involved with the BD incident during the Campania arc.
Besides, it’s nothing new that there is a high chance UT is involved in this arc…

So maybe he’s helping/working with/using the people at the Sphere music hall, maybe even for the sake of his own experimentation (new Bizarre dolls for example).
As for the Blue Sect, if we consider they’re a part of the Osiris company, maybe they actually got the idea to experiment on blood transfusion because of UT’s bizarre doll project.
UT gave them an example of what he could do when it comes to “resurrection” with the BD project during the Campania arc, so maybe they got inspired by him and his ideas and are trying for their own experimentation (the thing is, only a shinigami can work on cinematic records, so that could be why they’re trying with blood, especially since Lord Sirius probably isn’t dead yet).
If we consider Bravat’s words…

It seems “the light” of Lord Sirius probably refers to life while “radiance” is Violet’s blood, so Lord Sirius is probably not doing so great and it would be interesting to see if Bravat and Co. are convinced that maybe blood transfusion can stop someone from dying of old age or simply reverse the effects of natural aging for a time.
I had this idea because IRL some scientists are trying to prove that blood transfusions could be one way to reverse aging (note that I think it’s never happening but that’s not the point) and besides Ciel said…

Meaning that important people are investing money in the Blue Sect for a reason, but honestly as @thedarkestcrow said it’s very surely not because the S4 sing well or because of free food, haha!
However if the Blue Sect is conducting an experiment trying to show that stopping death (or reversing aging for a time) through blood transfusion is a thing, I’m sure many people would be ready to invest money in order to get more results since we all get old before dying.
They feel concerned by the results of the experimentation so they pay, that’s what I mean 🙂
Last thing is: Othello who just got introduced is from the forensic department and he was sent probably because the superiors might need someone to explain why there are so many cases of death by blood loss in London.
If the reason is “medicine experiment gone wrong and unethical” then it makes sense that someone with the scientific knowledge is sent rather than just a regular Shinigami.
That or if the Blue Sect is actually keeping Lord Sirius (and others?) alive with blood transfusions, the Shinigamis’ list for the collect might be all messed up and the Superiors sent someone to find an explanation. 🙂
TL;DR for the theory of this month’s chapter:
- The Blue Sect might be affiliated with the Osiris company introduced during the Campania arc.
- Lord Sirius is a very very old guy (varicose veins on his arms as a sign of old age for me) probably important in the Osiris company, who has blood pumped into him either so he can stay alive because he’s very very old, or because they’re experimenting to see if (”young”) blood transfusion can reverse aging (might be both actually).
- Violet (blood type AB, rarest) and Lizzie (blood type B, second rarest) are probably personal blood donors, in case the quantity of blood collected for all types each week isn’t enough to keep Lord Sirius (and maybe Lord Canopus?) in good shape.
Therefore they’re likely to be more in danger than anyone else at the Sphere music hall (because of anemia).
- Important people are supporting the Sphere music hall according to Ciel’s investigation, probably because the experimentation concerns them (my point being that they wouldn’t invest money if that was just to see Lord Sirius being a vampire or dealing with his blood disorder).
- There is a big chance the Undertaker is involved (the Osiris myth has a big parallel to the BD project besides the fact he’s most probably acquainted with the Osiris company since before the Campania arc) though his reasons are as always hard to pinpoint. It could very probably be for new BDs though.
- Considering ch108/109 and how Ciel is already on the move to go get them, we are probably in for a plot twist (involving UT).
Maybe he’s after Ciel, and that’s why he warned Bravat about Sebastian and also why Lizzie is involved in this arc in particular (especially since Bravat used her feelings to trap her inside the Sphere music hall). Unless Bravat is supernatural of course.
- Othello who is a part of the “geekiest division of the Shinigami dispatch” might be a hint that something unusual but scientific is behind all those cases of death by blood loss.
Whew, I’m sorry it was so long guys T_T but I hope it was interesting and it made at least some sense.
As always, it’s just a theory and it might get disproved next month for all I know, but it’s always fun to try assembling hints! ^^
Thank you for reading and feel free to ask anything! 🙂
