Black Butler Shinigami & Thorns of Death speculation ramble
Major musical spoilers!!! Read at your own risk! I recommend watching Kuromyu 2, the most beautiful death in the world before reading uwu
Okay so we know that to become a shinigami, a human must take their own life and in return they shall return as a shinigami as punishment. They also do not remember their past life, so they probably do know that they commited suicide, but they don’t know why. They also “work” until the day they are forgiven, but isn’t specified when or how they reach that point.
Shinigami’s work by reaping and collecting human souls and that they cannot interfere once the name is on the list. A human can have their life spared if the human is someone “ who has potential to be beneficial for this world “, which is rare according to the official wiki.
It is said that the thorns of death is caused by a soul of a human that is destined to die, but fight’s back against the shinigami. If that was the case, shouldn’t there be more shinigami’s who have the thorns? I doubt there are very few humans that accept death that peacefully and lets the shinigami do their thing.
William should have the thorns as well seeing that Thomas fought back against him during his first reap. it was also the only time we ever saw emotion out of that man. If anything, I’d reckon that most of the shinigami’s have the thorns of death.
In the second Black Butler musical we follow Alan Humphries and Eric Slingby. For those who haven’t watched it yet I don’t want to spoil, but the gist of it is that Alan has the thorns of death, and Eric is stealing human souls to try and save Alan (cue crying noises). A thousand human souls to be exact.
Speculation #1 : The Thorns of Death isn’t from souls fighting back, but rather the Shinigami showing compassion/emotions and/or second thoughts about reaping the soul. The Thorn’s are also not lethal. It is also not a disease or illness.
This is kind of a well known speculation but I wanted to put my thoughts into writing. We know that suicide is what makes a human a shinigami. Wouldn’t it make sense that they would be punished if they showed compassion or kindness to someone who is destined to die?
They were not kind to themselves, for whatever reason they took their own life and they were reborn as Shinigami. So if we play by the idea that their punishment for committing suicide as humans is to take human life, it would be ironic that they now feel or have second thoughts about taking it.
Their last act as a human is take their own lives, and in death they shall do it infinitely.
This brings us to the emotions part. We know that William is all about work. He is robotic in a way, emotionless and numb to everything as long as it doesn’t interfere with his work. As mentioned above the only time we ever see William show emotion is during his first reap, where Thomas essentially fought back, not wanting to die. Since then the William we know and love was born.
“If only I could understand their pain a little better”
“Thinking you could understand another’s feelings as they face death is sheer arrogance”
“Though I’ll never fully understand other’s thoughts as they await death, I feel I’ve gotten a bit closer”
"I was born alone in this world and alone I will die. If this is my fate, why are tears coming out of my eyes?"
- Alan Humphries, Kuroshitsuji Musical, The Most Beautiful Death in the World
Alan in and of himself is filled with emotions. He is empathetic and wants to understand feelings and emotions of the very people he is taking lives from. To the souls he reaps, he is death. Just as he took his own life, he also faced death. I think he feels the need to understand what they are feeling, whether it’s because he wonders deep inside how he felt when he died, or because he is just a pure and kind soul. (We do not know how Alan died, his Death Scythe is a long handled garden slasher and no other distinct qualities or sign as to how he died)
Shinigami will spend eternities watching cinematic records, observing human life, and death. It would make sense that a shinigami wouldn’t care if they took human lives, it’s just their jobs.
Ronald Knox has emotions, he flirts, he is playful and occasionally seen with human women and interacting with them. But he does not care about their lives. As seen in the Book of Atlantic he bids the human woman he was with goodbye, ending it with “if you’re still alive”, which he probably already knows that she does not survive. So it’s entirely possible for a Shinigami to display emotions and a personality, as long as it does not interfere with their job of reaping.
For this speculation emotions is what causes the thorns. And it can be stopped if the Shinigami stopped having feelings or empathy for the human souls they reap.
William for example, it would make sense that he is entirely void of emotions. If this speculation is right, then he would have the thorns from Thomas, which if he continued to feel or think about, would eventually kill him. If he did the same thing with every soul he reaped, he will die even faster. Getting rid of emotions would essentially get rid of/ not have the thorns, hence surviving.
Either way, William may or may not have eradicated the thorns, but if he stopped it early enough I don’t think a small amount of thorns would be lethal. He may still feel the prick or pain of it, but it will not lead to his death.
Alan on the other hand is portrayed naturally empathetic, he is filled to the brim with emotions and thoughts about the souls he reaps, and as long as he continues it, the thorns will only sink deeper.
In my opinion it’s more of a consequence than an illness if we go by this speculation and it is entirely avoidable. After all, they took their own life selfishly, it is now their punishment to take others, but now they hesitate? Or feel for the humans? It’s a baffling concept considering it goes against their whole existence.
Shinigami’s are the neutral ones. They hold no opinion over the life or death, they just take. So for them to not be neutral, if would still make sense that they get the thorns as punishment/consequence.
Speculation #2: A thousand stolen human souls is needed to “cure” the thorns, but why?
Let’s say that there is no other way to get rid of the thorns. Once you have it, there’s no stopping it. (We’ll forget about William’s case and focus on Alan)
In the musical we see Eric taking the souls for himself to collect and eventually give to Alan. He goes out of his way to make a whole opera play to garner enough humans to take souls from.
But why would this work?
Selfishness. This ties back to why the thorns were there in the first place.
Feeling or trying to understand human pain or emotions is what gave them the thorns, so if a shinigami would take so much lives so selfishly, so greedily, to save themselves, it would negate the thorns that they acquired.
Having no regard for human life would most likely get rid of the thorns purely because it contradicts the thorns presence in a shinigami.
But isn’t taking human souls for themselves against the rules? Why, yes, yes it is.
Which is why Eric was sneaking around doing it. He only formulated the mass soul reaping when he realized that Alan does not have much time left, and he needed the souls immediately to save him.
Let’s talk about Eric Slingby for a moment.
“And yet somehow.. somehow I have finally found... one fragile ray of light.
“Forgive me Alan, I can’t give you up. I just can’t give you or your life up!”
-Eric Slingby, Kuroshitsuji Musical, The Most Beautiful Death in the World
We talked about how having emotions or feeling empathetic towards humans cause, thorns. But it doesn’t seem to apply to shinigami relationships.
Eric is literally intervening with Alan’s eventual death by collecting the souls, so do the rules of being neutral not apply to them? Are they free to save each other?
I don’t really see a problem with this, I can kind of see that it might not be included in the rules since well, they aren’t human, and it just makes the story even more heart-wrenching.
Eric also has emotions and a personality, and even though he doesn’t understand why Alan is feeling the way he does when it comes to human emotions towards death, he still sees him as a friend and wants to save him. It just goes to show that even shinigamis can have healthy relationships. (cri)
Okay we’re back. During the musical Alan learned that it was Eric who was taking the human souls to save him, and he immediately tries to stop Eric. They have a bittersweet moment and decide to run away together and Eric promising not to kill anymore to get souls, and they leave their glasses behind, signing their resignation.
But the thorns didn’t stop. And eventually Alan is on the verge of death, and Eric breaks his promise, he wanted to save Alan no matter the cost. Eventually Eric needed one more soul to complete the task, and the only human left that he could kill quickly was no other than Ciel Phanthomhive. But just as he was about to kill Ciel, Alan dived in between, Eric’s death scythe killing him.
Eric was devastated, and begs Sebastian to kill him which he does with Alan’s death scythe. Everything he had done was to not lose Alan, but in the end fate was cruel to them. As the very thing he wanted to protect disappeared by his own actions, he essentially killed himself once more by asking Sebastian to take his life.
He lied beside Alan, in his second time tasting death for himself, at least in death they were still together.
The souls he collected erupted from his body and rained down on the ground, Ciel and Sebastian musing that the souls were beautiful, white, and pure, it was innocent. It was the most beautiful death in the world.
So what would happen if Alan didn’t take the souls? Would Eric just have 1000 souls with him? Would he return the souls to the dispatch center? Would they be fired? I don’t know really, but all I can most likely assume is that everything Eric did to get the souls would be useless and for naught. Alan I think would have died either way, he would never have taken the souls.
I can see Alan and Eric still alive and happy together if they ran away earlier and the thorns weren’t as bad.
Another ending would be Eric letting Alan die per his wish, and Eric turning into an emotionless void like William from the sad event. I can see Eric getting the thorns for himself as he would probably remember Alan whenever he takes a human soul, and the guilt of not saving him would also probably eat him alive. A lose-lose situation.
Even another one would be Alan surviving if speculation #1 was true, but then he would also be emotionless and unfeeling, unless he figured out how to exclusively not feel for the humans and their souls, but that’s a far fetch, I just don’t see Alan doing that. And even if it did happen, I'm quite sure Alan and Eric's dynamic would change and it wont be the same. Also a lose-lose situation.
It’s a bitterweet ending for Alan and Eric, I can only cry and curse at the world so much for giving them such fates.
I guess that’s what fanart and fanfiction is for amiright?
If you read everything and got to this point, wow, don’t you have a life? Just kidding. I hope you enjoyed and let me know your thoughts if you like.
I might write more of these if I find more stuff I feel like is interesting, or people can give suggest stuff through dm’s or messaging.
Stay safe, healthy, and hydrated!
Much love, Ames
