Nioh has been very depressed recently. He often hears a voice after sleeping, saying something like: "Believe me, believe me, I'm awesome. With me, you are absolutely invincible."
Nioh originally thought that it was just the sequelae of reading too many novels, until the next day, he opened his eyes and saw an unfamiliar ceiling.
Just when Nioh was still trying to accept the reality, the mean voice in the dream sounded again.
