Concepts of religion inside Bleach — Aizen backstory headcanon character analysis Part 2
AGAIIIINN my favorite client in psychoanalysis
Or rather how you accidentally raise a future god-complex mastermind by teaching him how to pray wrong. I had two itches in my brain that lead me writing the fanfiction The Nameless Moon that would NOT leave me alone, which is basically:
1.understanding his god complex and overall personality development ( my ramblings here)
2.if you elaborate on his hatred for the soul king how did it start at the roots
Because the last scene before he was sealed just did not left me alone. The way he talks about the Soul King, the system, the fact that people like Kisuke just… accept it? That reads so personal. Like offended personal.
And I kept thinking:
this is not just “I discovered a truth and didn’t like it” — this could be “I have been surrounded by this my entire life and I am DONE.”
So my brain went: okay… what kind of environment creates that level of reaction?
And the answer that made way too much sense was:
Being raised inside a belief system that nobody ever questions. And being forced upon it for years and so THIS headcanon was born
— (and my fanfiction…)
And yes, I KNOW we will probably never get Aizen’s backstory, which is exactly why I will continue believing that THIS could be one key element in his personality development as if it would be canon with zero shame!!!!!!
Soul Society already has the framework for religion( Just look for 2 seconds)
Kubo never goes: “Here is the official religion of Soul Society.” But it doesn’t need to, because the pieces are literally just… sitting there. LOOOK
Jūshirō Ukitake being taken to a temple as a child while his parents pray for divine healing
The shrine aesthetics, purification rituals, spiritual hierarchy
nobles being treated like inherently “better beings” (which historically ALWAYS ties back to divine justification, let’s be real!)
cursed/sacred objects like Nanao’s Ise family artifact(which is VERY on brand for Shinto ideas of objects holding spiritual presence or becoming… not so friendly if mishandled)
So if you take all of that and just go one step further — im not inventing… I’m LITERALLY just connecting dots right now—
it is almost impossible that something similar like a religion would NOT exist. And realistically, it would resemble Shintō and Buddhism.
Not copy-paste versions, but universe logical adapted ones, because Soul Society is basically “afterlife edo Japan but make it structured and slightly concerning.”
But there is a Problem: It’s all built on a LIE (big oops)
Now here’s where it gets REALLY funny in a dark way. Because the god the Soul King? Is not a god in the way people would believe.
He is:
a linchpin
a system requirement
basically a cosmic infrastructure corpse
And the best part? It is said that most people don’t know that. Only higher authorities and nobles do. Which is… yeah, not suspicious, totally normal, love that.
So what happens?
They distort the truth to make it practical for their own agendas controlling the narrative ;D
Congratulations, you now have a concept of a religion and the means to weaponize it
I believe it would look like
temples built around partial truths
rituals that reinforce order
teachings that go: “this system is sacred, don’t worry about it everything is good, everything is like it supposed to be :)“
So is it fully fake?
No.
Is it fully true?
Also no.
I would say it’s a very functional misunderstanding ;D
The pros, this system gives:
keeps some people calm
keeps some people obedient
keeps some people from asking the wrong questions
Monasteries: or how professionally teach people not to ask questions
If temples like Jūshirō was taken to exist, monasteries probably do too. And what would they teach?
Not:
ultimate truth
deep enlightenment
But:
acceptance
detachment
obedience
and the art of NOT asking “why”
While they say they free you from illusion. In truth they are just making you comfortable living inside of it.
NOW SPEAKING OF ILLUSIONS: AIZEN — Put him in there :D
As a Child. (if you hear a clapping sound it's me clapping my own back for finding this smooth transition xD)
Young, observant, already-too-smart-for-his-own-good Aizen. And like he is put there forcefully like in a sense he was brought up there.
Which means:
no family attachment
emotional distance is normal maybe even wished upon
identity is shaped through expectation, not true self (important)
intimacy = forbidden
questioning = problem
But he doesn’t believe without explanations. So he studies it artificially.
This is where everything goes wrong. Aizen always did notices things. Always too many things. Instead believing in the divinity he sees unquestioned structure. And he noticesed if he rebels to openly it would be inefficient.
So he replicate it. Perfectly.
Faith is remarkably easy to imitate… once you understand the pattern.
(he would maybe think something like that)
Monk Training: more like psychological conditioning
For Aizen, being trained as a monk is not spiritual. It was imposed on him, but it turned out to be useful in the end.
Since he learns in that time:
how to control his expressions
how to appear harmless
how to say exactly what people expect to hear (very important)
how to suppress what should not be seen
One key thing some monasteries practice is mediation— for him it wa patience training. The kind you need when your plans take literal centuries.
So Aizen did not just learn how to lie well and how to be basically a trickster shout out to @kitsmits —but rather he understands why people want to believe the lies in the first place! Which is… worse, for his future victims!!!!
The Emotion during that all
Before his ambition.
Before his rebellion.
There was his boredom.
I agree with the general consensus that he doesn’t need a sad abuse backstory— boredom in his case already plants the seeds for later existential havoc.
Because it is not normal boredom, more like:
intellectual suffocation
repetition without depth
a world that never challenges him
Because even since a very young age Aizen doesn’t accept things “just because they are.” So at first, his goal is not domination in this headcanon.
It’s escape.
So becoming a shinigami = escape (?)
Power = maybe finally something real? (spoiler: KYOKA SUIGETSU. )
Then he becomes a shinigami.
Because power looks promising. Power feels real. Maybe THIS is where meaning is.
Except. The tragic of it all. He’s too good.
learns too fast
surpasses others immediately
And once again:
he hits the ceiling way too early. The boredom returns. Again. AND now he has a weapon that can literally shape the concepts of reality for other people, which does not help—at the end devaluing anything that seems to be real. Like in his pov does the concept of real even matter?!can he even have the same concept ?! MAYBEEEEE if he would care for other people.... But well u know :)
The Existential Crisis
And then at some point comes the moment in him which would be:
“This is it for me now?”
the monastery was shallow
And this system is the same
the world doesn’t expand further
the “god” isn’t even what they claim
When it stops being boring and starts being insulting
Because now it’s not just emptiness and boredom. Now it’s offensive. Since he surpassed all!
And yet he is:
still controlled like the monastery
still expected to obey like the monastery
still placed under authority he never chose like the monastery
I think he would think something like
I have surpassed everything they taught me… and they still expect my submission?
Inside a system pretending to be divine.
So What’s Left?
From his perspective:
He cannot just live in this world accepting the lie that are placed to control people-like for example, Kisuke does! Because this world is literally EMPTY for him! He has no bonds in this world that make it bearable. Like Kisuke has Yoruichi etc. (I believe Kubo said somewhere that Aizen is that what Kisuke would have become when he had no attachments and if he had been more ambitious)
And he cannot just destroy and cause havoc just for the sake of destroying like Tokinada does— not stimulating enough.
So there is only one option: the hogyoku. The last final step and while using it to transform something god like he will destroy the last string that is attached to him that tries to controll him. The system itself. And since he knows that this world works on the performance of duty and morals but at the end it is build on a lie. Then he thinks it is best to keep perform a lie but now a functional one that works for HIS agenda.
Final Thought (aka why I think this backtory headcanon could work)
Aizen is here THE logical outcome of a system that teaches
devotion without truth
obedience without understanding
belief without ever allowing the question why
+ being ridiculously powerful, fatally ambitious and very important a natural lack of emotinal empathy.
So his thought could have been when he set his goals:
Why should I submit to a false divinty whose purpose is to controll me? If its very design is a pathetic lie, then pathetic morals like honesty are merely another chain. I refuse to remain chained to patheticness.
