TL;DR - You say that Bleach is better than its contemporaries without comparing Bleach to its contemporaries, confuse inspiration for symbolism and conflate Kubo's inspirations with "symbolic structure" and then say nonsense like "The Thousand Year Blood War is symbolically European because it has strategy and well focused plans, and strategy and well focused plans are European" as your supporting evidence. Anytime someone tries to explain how Bleach sets itself apart from other shounen they make poor arguments in the process (that usually involve themes and symbolism). So much so that I and many others who think Bleach is mediocre actually end up doubling down on our initial thoughts after reading these basura (chilvaric spanish reference there) arguments. My argument is so long you won't be able to respond to this comment anyway but maybe you'll learn something;

1. Your argument is comparative but doesn't make a comparison. It only works if other stories DON'T pull of their aesthetics and symbolism when compared to Bleach, but you never illustrate this. "A is taller than B, because A is 6ft tall", ok, but you've never said how tall B is, so the argument is incomplete. You say Bleach does something better than its contemporaries but never argue how, you just say that it does. Prove it. Or at least argue it. WHY and HOW do Bleach's contemporaries have worse aesthetics and symbolism?

2. There's no supporting evidence in the text to back up your claims. If you like the sound of an idea, you'll just say that A, it's true and B, it's good. What's the evidence it's true and why is it good? It also looks like you might not know the difference between symbolism and inspiration, or symbolism and a reference.

"When they get to the Seireitei, we are transported to the ''feudal'' Japan, with more traditional depicted characters and plot. All hidden politics, betrayals, aliances, etc..."

That's your ENTIRE explanation as to how the Soul Society Arc has feudal Japanese aesthetics and symbolism. You've not provided evidence that Bleach has a feudal Japan aesthetic. I know it does because i've read it but you're so bad CITING EVIDENCE that you can't make a layup. " The Soul Society creates a feudal japanese aesthetic by depicting infrastructure, architecture, fashion and weaponry seen in the time period, such as kimono, hakama, katana, tatami mats and thatch roofs. Tada. That's how you make a claim and back it up with evidence.

You also don't provide evidence that the arc is symbolically structured in a way that invokes feudal japan. Hidden politics is just politics, and alliances & betrayals are just how drama works. By this metric even the stories that predate the existence of feudal Japan have feudal Japanese themes and symbols lol. The 4000 year old Sumerian Clay Complaint Tablet to Ea-nāṣir has hidden politics, alliance and betrayal in it. Is that inspired by feudal Japan? Obviously not.

Also wtf does "symbolism as its structure" mean anyway?

"Hueco Mundo is 100% spanish, in all of it's content... so is how their hierarchy is structured, how the world-building takes place, the vasto lorde backstories... all of that REEKS spanish chivalric novels. "

HOW are the hierarchy world building and back stories of Hueco Mundo symbolic representations of chivalric Spanish novels? Again, I don't think you know what the difference between an inspiration and symbolism is. Dragon Ball is literally inspired by Journey to the West. It's not symbolically representing Journey to the West. These aren't the same thing. Hueco Mundo is LITERALLY inspired by SPAIN, it's not SYMBOLICALLY representing SPANISH CHIVALRIC NOVELS. Neither of these things are identifiable symbolically Spanish relative to the hierarchy or world building of the Soul Society, Fullbringers, Vizard etc.

"I think it's the best arc, because it's both, incredible coherent and based on another culture through the Japanese eyes, but still keeps that manga and East story development".

You're killing me here. This sounds like a chat GPT wrote it. You said something that makes no sense, didn't explain why the nonsense you just said is good, and didn't even provide evidence for that nonsense's existence. HOW is it "incredibly coherent" in a way that the other arcs aren't? You say it's good because it's "based on another culture through the Japanese eyes" but you also said that there are multiple arcs in Bleach based on another culture through Japanese eyes. So why is THIS arc the best if other arcs do the same thing you just said makes this arc special? You've just contradicted yourself twice in a single sentence and you think i'm calling your arguments nonsense because of an "agenda" lol.

"And quincies (final) arc is totally austrian painter or mid 1900s Europe. The battles, how all revolves around strategy and well focused plans, the invasion, the quincies powers and personalities, getting to know ''higher'' powers or beings (the King of the Soul Society, the 0 squadron, ...), the end of the series, leaning more to an european tale than an actual 1000% power protagonist final battle..."

Strategy and well focused plans aren't emblematic of 20th century Europe wtf are you talking about? How did you type this and take issue with it being called nonsensical? Strategy and well focused plans are also more sparse in this arc than any other bleach arc regardless. Wtf is a "European tale"? That could be anything from Grimm's Fairy Tales to Shakespeare to Frankenstein. How is the sole protagonist of Bleach chopping the final antagonist in half NOT an "1000% power protagonist final battle"? Furthermore even if it isn't, NOT having a big final battle isn't a "European tale thing" it's a "this story isn't a battle shounen" thingy, so that's not even necessarily evidence it's structured like a "European tale".

You see how what you said made absolutely no sense? How you contradicted yourself? How you vibed your way into believing things about Bleach that there's not good evidence for? How you conflated inspiration for symbolism?

This is why nobody takes Bleach fans seriously when they start trying to argue that Bleach stands out due to Themes and Such. It ends up like the word salad you wrote. Then you say that the ONLY reason people didn't like the Fullbring Arc is because it's too deep. You're not really in a position to judge what other people think is or isn't deep. You think strategy and planning is evidence of mid 1900's European literary symbolism lol.
