In short, Nagakon Eira did leave Kaneki on that day (you know). After Kaneki experienced the events of Hiyo, Sasaki, Wang Jin, and Ryukin (240), he fell into the Demon Slayer World on his way to pay homage to Mr. Arima and talk to Ying (his tombstone).
①Kaneki's appearance after entering Demon Slayer is melatonin, and his strength is the ceiling of Demon Slayer
②CP is Nagakon Hideyoshi
③I don't know how to write a sweet feeling. If you like it, that's fine. If you don't like it, you can quit.
④ I have never read the comics, only the anime. Please correct me if there are any mistakes. However, I am a senior in high school and will try my best to find time to correct them.
⑤ Everyone must survive (make a fist), including Sister Huazhu (make a fist)
Intention: Relaxed
