Demon Slayer: Kimetsu no Yaiba

[Buffalobiian]

They never used it because it was supposed to be a hidden palace of refuge. Muzan's goal ultimately was to have immortality. Destroying the demon slayers would help, but ultimately it probably doesn't bother him all that much. Like he says, he's got time.

The Biwa demon also stays in the castle, so if they got a Hashira in there and killed her then that's a huge asset lost to Muzan without much gain. Killing a Hashira or two doesn't mean much to him.


Now. Now that Nezuko is sun-resistant, Muzan has something to play for. Demon Slayers are hiding her, so he's now out to wipe them out in order to get to her. When he had the other demons out and about to infect people + hopefully find/develop into a cure, the castle was mostly empty.

THat's why he's bringing ALL the demon slayers there now, makes sense /s.

He could just teleported important assets to outside Japan. Just get Biwa to Europe where there's no Hashira.

Because he's got all the demons there.

Once the cure was found, Muzan didn't bother letting demons roam free. They're all in the castle now ready to pounce the demon corps.

And Biwa stays IN the castle. She doesn't just go places.

If immortality is the only goal, he already has it if he just closes away in the pocket dimension. Obviously he misses the sun and wants to return to the daytime earth, perhaps ruling it too, otherwise his whole 'making subservient demons' thing doesn't make any sense, neither does searching for the 'cure'. Having time means he can wait for this unique group of Hashiras capable of killing uppers to wither/die out while Nezuko becomes alone in the world as she ceases to age. Being able to draw threats anywhere into this dimension means he can choose when and where to engage, effectively, putting his forces to the best use with the least risk. I don't buy that he didn't consider that with his time and his paranoia... even if he sees the Hashira as below him, he has experienced fear of death before from the earring swordsman, so simple ignorance won't cut it for an excuse, either.

Because of all of that, right now, that whole climactic scene is unprecedented and silly if there is no catch or drawback; I don't want to headcannon it because I think it is really lazy/rushed writing as is. I hope the power turns out to be another demon's who had to do prep work or meet a condition for this to happen. Just a pet peeve of mine.

Any yeah, not targeting Nezuko with it is absolutely bonkers.

I'm assuming it can only target people the eyeballs have located. And the eyeballs still haven't found Nezuko.
