Main: I liked it. Could do without the circus part but an otherwise interesting and solid story. Would definitely recommend as a first reading of Junji Ito works.
2nd: What the fuck? Am I supposed to feel sad or horrified? That death was dumb and unnecessary. There was no reason why he should've been in that crawl space to begin with!
3rd: This might be my second favorite Junji Ito story (first being Uzumaki). I wish we could actually see the deformed human leaving the hole instead of that cliffhanger but I also kind of like that cliffhanger. Leaves more to the imagination on what that thing is anymore and what it'll do once it leaves the hole.
