Major spoilers

Things that altered my brain chemistry in the Infinity Castle movie - "Akaza returns"

- Gyomei carrying the responsibility for the Master's plan alone because no other Hashira would have accepted it.

- Muichiro remembering Kagaya staying next to him when he was hurt and calling him his father with tears in his eyes (he s only a child)

- How clearly we could hear Shinobu's bones break and her lungs filling up with blood.

- Kanae's voice when she ordered her to get up.

- Zenitsu waiting just a bit before using his 7th form, hoping that Kaigaku would at least regret what he did. Hoping to catch a glimpse of the brother he respected in him before killing him.

- Zenitsu calling him "Aniki" (older brother) and apologizing before taking his head.

- "Zenitsu, you are my pride and joy"

- Kanao's bloodcurdling scream when she saw Shinobu dead, limp in Douma's arms.
