#infinity castle

- Akaza's entrance and Tanjiro sensing his presence before actually seeing him.

- Giyuu managing to catch Tanjiro just before he hit the floor and died.

- "you'll have to get through me first before you kill Tanjiro !"

- Shinobu showing how angry she actually was after so much time wearing the same smile on her face

- Muichiro and Gyomei cutting through entire buildings of the Infinity Castle together.

- the lower ranked demon slayers grouping around the Hashira to clear their path to Uppermoon demons and Muzan himself.

- Kiriya taking charge of the Corps, and Kagaya guiding him gently with his spirit

- Kiriya not allowing his sister not even one second of grieving when her eyes filled with tears. There was no time for it then.

- everyone having a role to play together - even the crows, the retired Hashira and the Kakushi.

- Giyuu dragging Akaza through multiple buildings of the Infinity Castle even before awakening his mark

- Giyuu immediately forcing himself up to his feet again, after being dragged to hell and back, when Akaza tried to turn to Tanjiro and kill him.

- Even while Tanjiro was passed out, Giyuu using the last of his strength to attack and take full on hits from Akaza so he didn't have the chance to step closer to him.

- "Don't die, Giyuu..." (his crow pleading with him at the end messed me up the worst)

- Tanjiro tearing up when he heard the news of Shinobu's death.

- Muichiro asking Gyomei about the Master first thing after falling into the castle.

- Obanai immediately telling Mitsuri to calm down and to hold hands so they don't separate when they fall.

- Hakuji's scream when he saw Keizo and Koyuki dead.

- His promise to protect Koyuki and then the next frame being him hugging her dead body to his chest while crying.

- Akaza saying "i have to kill that useless person" , then killing himself and refusing to let his body regenerate. He was begging for death by that point.

- Koyuki choosing to go to hell with him. Calling him "my dear" the way a wife calls her husband.

- Giyuu immediately trying to reach Tanjiro after the battle, but finally collapsing next to him perched on his sword.

- Tanjiro's father using the Hinokami Kagura (his version of it) to kill the bear before it got to their family.

- Tanjiro's eyes lighting up like Yoriichi's when he finally unlocked the See-through world.

- Obanai telling Mitsuri they were going to do the same after hearing Giyuu and Tanjiro defeated Uppermoon 3, both of them not knowing what was actually next.

- even if he hated him, Obanai thinking "congratulations, Tomioka," after hearing he survived and won the battle.

- Murata actually insisting that Yushiro take good care of Zenitsu, even while being spooked by him being a demon.

- seeing the difference between the rudimentary Water Breathing tehnique used by Murata and the actual mastered tehnique used by Giyuu (and Tanjiro).

- Giyuu taking the full hits for Tanjiro when not even "Dead Calm" could fully work anymore.

- Tanjiro saving Giyuu just as he almost died the same way Rengoku did - with Akaza's fist through his torso.

- Giyuu, who didn't think he was worthy before, being called the strongest Water Hashira he has ever encountered by Akaza. (He was fully locked in)

- even if Tanjiro was as strong as a Hashira by that point, the way they depicted how Giyuu was still more experienced and syncronized to Tanjiro's attacks perfectly, like guiding him.

- the way they also depicted the difference between lower ranked slayers, who needed groups of 4-5 to defeat regular demons, and Hashira-level slayers, who could oneshot higher ranked ones.

- Shinobu's sobs when Kanae finally died in her arms.

- "Why couldn't I be taller ?"

- Douma toying with Shinobu before her final attack (that took even him by surprise.)

- Giyuu refusing to talk to Akaza and refusing to give him his name - contrast from Rengoku who presented himself from the beginning and stated his position and name. Giyuu ain't playing with those demons (he's so shady)

- Genya searching for his brother the moment he fell into the castle.

- how small Muichiro looked next to Gyomei.

- how horrifying and dire the situation looks throughout the castle, and how all the Hashira put their life on the line to try and keep the other slayers from dying as much as they could.
