Which ones? I’m pretty sure everyone was introduced
Or do you mean the other three characters in the inside of the pit cause those are the other ghosts (the cicada, glasses doujin lady, and I believe the swimming guy but might be someone else)
the one w the scar right thru his face and that kid with x x hairpins. (is it the second female lead's sibling?)
The scar guy was introduced with the exorcist siblings in ch 17
The girl with the hair clips and bald guy showed up for the first time in ch8
who are those two character at chap 34?new ones? i dont remember them
