Tanjiro killed countless ghosts, but he couldn't kill himself in the mirror.
Three years after the war, the ghost marks on Tanjiro's palms continued to burn. In the mirror, the slaughtered family was having dinner - the mother handed over sweet potatoes, and Purgatory patted him on the shoulder. Breathtakingly perfect.
"Trade them with your memory." He changed. The next day, I forgot about water breathing and bit into a sweet potato, leaving my mouth full of maggots.
Nezuko pinched his throat and her pupils turned purple: "Brother, I really want to eat people."
Wubi laughed wildly: "The one you protect is a monster after all."
Tanjiro raised the knife and stabbed his heart - not because he wanted to die, but because he finally understood: some wounds can only be lived with.
