I'm japanese, but the first exposure was the English version of the comic.
Translation is excellent, and onomatopeias are seemly totally rewritten by Shiro himself.

Trouble was that one part doesn't quite make up the story right;
later I obtained the original japanese comic and knew the truth.

2 pages of Porn-ish part was totally ripped off in the english version.
That part itself wasn't the major part of the story, but omission was enough to make your brain full of question marks.
