@gathink yep, 9 in total from his fanbox, 1 one original with sadako 2 a bestiality of kimetsu no yaiba with insects 3 and 4 this ones 5 another from kimetsu with tentacles 6, 7, 8 and 9 are from Last origin, three with bestiality (lion, dogs and a bull) and the last one with a milf that supposedly is gonna have a second part but the artist is in a standby
@gathink There are only 2 parts of this story it does say 3 and 4 but when you translate the title on fanbox the numbers disappear. The numbers are there to show which month it was released 3 stands for march and 4 stands for April and there are other stories on his fanbox that feature characters from this manga, but those are not related to this story. The artist has said on his fanbox there might be more parts of this story someday.
