Demon Slayer: I was taken home by Shinobu Kocho at the beginning.

Since he became conscious, Yangquan had been living in a dilapidated house. Having lost his memory, he didn't know where to go, so he stayed there.
one day
A girl as graceful as a butterfly suddenly appeared, following the soft moonlight. Yangquan learned from her that he had become a ghost.
The girl wore a gentle smile, but it didn't reach her eyes. She said she wanted to get along with ghosts, yet she used that nimble knife to stab Yangquan through the heart.
What Yangquan never expected was that in the near future, a girl named Shinobu Kocho would cup his face and stare straight at him.
"Mr. Yangquan, please stay with me forever!"
..........
It was a very long time before Yangquan heard his own answer.
"it is good"
