During the protracted war, Fei Niang, the seventh ancestor, and Crowley, the eighth ancestor, accidentally traveled to Demon Slayer: Kimetsu no Yaiba due to the impact of the war. Their bodies shrank and became babies waiting to be fed. Tanjiro's grandfather, who happened to be passing by and had just been married for two years and had a son, saw him. He couldn't bear to see the two big babies suffer, so he adopted Fei Niang and Crowley home.
So Fei Niang and Crowley accidentally became the uncles of the unborn protagonist Tanjiro. They learned the Breath of the Sun and the Dragon of the Sun together with Tanjiro's father since childhood.
When they were 12 years old, Fei Niang and Crowley recovered most of their strength. In order to continue to restore their strength, the two sneaked into the mountains to suck the blood of animals. Yes, for some unknown reason, even the blood of animals could be used by Crory and Fei Niang to restore their strength. In the deep mountains, Fei Niang and Crowley also encountered ghosts for the first time, and they also learned the truth behind the world for the first time. There are ghosts.
"Aha." Fei Niang patted the ghost's head and couldn't help but feel happy when she saw the ghost queen who kept making threats.
"Ghost? I just want to take a look. Is there any difference from what I know?" Fei Niang looked at the ghost that had been wiped out in ashes, curled her lips, and she and Crowley smiled at each other.
Intention: Struggle with each other and make progress with each other
