Right so lets do upper moon 1 first, the image above is purley his bda, hence completely unpredictable by transparent world, as u can see it is also an area wide attack in which NONE OF THEM could dodge, adding more marked hashira here would not change the effectiveness of this attack, in addition without genya here and if it were only 9 hashira we wouldn't have the panel where he says "i cant use techniques", also techniques refer to breathing techniques, for some reason he doesnt use his bda like above alot in the fight, only 2 times and both times the hashira almost die, so if all 9 marked hashira were fighting this dude, i dont see how u could kill him provided

He used the insane movement speed he has instead of standing still

The hashira dont magically find gaps to slip through in attacks that are completely unpredictable

He uses his BDA independent of his blade (by growing blades out of his sword or body)

They will eventually get tired and lose, u cant really get near the dude like look at the panel, also another thing he is faster than all the hashira, so whats stopping him for moving around spamming attacks from unseen angles, NOTHING, well plot armour was but like inba realistic fight, nothing

ONE massive supporting evidence i got is the fact that sanemi almost died or got deemed useless twice if not for other hashira helping him, but the attacks hit all the hashira so gyomei cant protect them all, and muichiro wont randomly spawn in if he is already in the fight this time, if sanemi himself is unable to avoid it then why would giyu or tengen be different

For upper moon 2, i dont think u guys understand how broken his bda is, he can make clones of himself that are just as strong as him (ish) so he can make it a 7 v 9, 7 domas vs 9 hashiras, and each clone can use ice bda too, twin how the fuck are the hashira winning?

Simply look at the image: nothing was stopping Gyutaro from driving his sickle straight up into Tanjiro's brain to instantly kill him. The attack initiated by Tanjiro was far too risky and foolish given that Gyutaro had a free arm holding a sickle, as clearly shown in this frame. Despite this being a scenario Tanjiro should not have survived, he managed to live anyway.

When looking at the mouth from underneath, the layer of bone separating the oral cavity from the brain is extremely thin and would be easily pierced by a weapon like Gyutaro's sickle. All he had to do was fully extend his arm, tilt his wrist slightly forward, and thrust upward—which would have ended the series right there. This detail is crucial to highlight because it cannot be justified even through in-universe plot logic; Gyutaro already knew his poison's effectiveness had dulled, making it senseless for him not to deliver a finishing slash after Tanjiro mistakenly believed he was invincible.

Hence this is bullshit 🙄
